By changing the value of -* the literal in the instruction before the code is loaded, the -* driver can change algorithm. -* -* CPUSAVER_DWORD - This is the location of the instruction that loads -* the dead-man timer with its inital value. By writing a 16-bit -* value to the low word of this instruction, the driver can change -* the timer value. The current default is either x600 or x800; -* experiments show that the value probably should stay within the -* range of x200 - x1000. -* -* CPUSAVER_BUNDLE_MAX_DWORD - This is the location of the instruction -* that sets the maximum number of frames that will be bundled. In -* some situations, such as the TCP windowing algorithm, it may be -* better to limit the growth of the bundle size than let it go as -* high as it can, because that could cause too much added latency. -* The default is six, because this is the number of packets in the -* default TCP window size. A value of 1 would make CPUSaver indicate -* an interrupt for every frame received. If you do not want to put -* a limit on the bundle size, set this value to xFFFF. -* -* CPUSAVER_MIN_SIZE_DWORD - This is the location of the instruction -* that contains a bit-mask describing the minimum size frame that -* will be bundled. The default masks the lower 7 bits, which means -* that any frame less than 128 bytes in length will not be bundled, -* but will instead immediately generate an interrupt. This does -* not affect the current bundle in any way. Any frame that is 128 -* bytes or large will be bundled normally. This feature is meant -* to provide immediate indication of ACK frames in a TCP environment. -* Customers were seeing poor performance when a machine with CPUSaver -* enabled was sending but not receiving. The delay introduced when -* the ACKs were received was enough to reduce total throughput, because -* the sender would sit idle until the ACK was finally seen. -* -* The current default is 0xFF80, which masks out the lower 7 bits. -* This means that any frame which is x7F (127) bytes or smaller -* will cause an immediate interrupt. Because this value must be a -* bit mask, there are only a few valid values that can be used. To -* turn this feature off, the driver can write the value xFFFF to the -* lower word of this instruction (in the same way that the other -* parameters are used). Likewise, a value of 0xF800 (2047) would -* cause an interrupt to be generated for every frame, because all -* standard Ethernet frames are <= 2047 bytes in length. -*************************************************************************/ -

By contrast, the GNU General Public License is intended -to guarantee your freedom to share and change free software--to make sure -the software is free for all its users. This General Public License applies -to most of the Free Software Foundation's software and to any other program -whose authors commit to using it. (Some other Free Software Foundation -software is covered by the GNU Library General Public License instead.) You -can apply it to your programs, too. - -When we speak of free software, we are referring to freedom, not price. Our -General Public Licenses are designed to make sure that you have the freedom -to distribute copies of free software (and charge for this service if you -wish), that you receive source code or can get it if you want it, that you -can change the software or use pieces of it in new free programs; and that -you know you can do these things. - -To protect your rights, we need to make restrictions that forbid anyone to -deny you these rights or to ask you to surrender the rights. These -restrictions translate to certain responsibilities for you if you distribute -copies of the software, or if you modify it. - -For example, if you distribute copies of such a program, whether gratis or -for a fee, you must give the recipients all the rights that you have. You -must make sure that they, too, receive or can get the source code. And you -must show them these terms so they know their rights. - -We protect your rights with two steps: (1) copyright the software, and (2) -offer you this license which gives you legal permission to copy, distribute -and/or modify the software. - -Also, for each author's protection and ours, we want to make certain that -everyone understands that there is no warranty for this free software. If -the software is modified by someone else and passed on, we want its -recipients to know that what they have is not the original, so that any -problems introduced by others will not reflect on the original authors' -reputations. - -Finally, any free program is threatened constantly by software patents. We -wish to avoid the danger that redistributors of a free program will -individually obtain patent licenses, in effect making the program -proprietary. To prevent this, we have made it clear that any patent must be -licensed for everyone's free use or not licensed at all. - -The precise terms and conditions for copying, distribution and modification -follow. - -TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - -0. This License applies to any program or other work which contains a notice - placed by the copyright holder saying it may be distributed under the - terms of this General Public License. The "Program", below, refers to any - such program or work, and a "work based on the Program" means either the - Program or any derivative work under copyright law: that is to say, a - work containing the Program or a portion of it, either verbatim or with - modifications and/or translated into another language. (Hereinafter, - translation is included without limitation in the term "modification".) - Each licensee is addressed as "you". - - Activities other than copying, distribution and modification are not - covered by this License; they are outside its scope. The act of running - the Program is not restricted, and the output from the Program is covered - only if its contents constitute a work based on the Program (independent - of having been made by running the Program). Whether that is true depends - on what the Program does. - -1. You may copy and distribute verbatim copies of the Program's source code - as you receive it, in any medium, provided that you conspicuously and - appropriately publish on each copy an appropriate copyright notice and - disclaimer of warranty; keep intact all the notices that refer to this - License and to the absence of any warranty; and give any other recipients - of the Program a copy of this License along with the Program. - - You may charge a fee for the physical act of transferring a copy, and you - may at your option offer warranty protection in exchange for a fee. - -2. You may modify your copy or copies of the Program or any portion of it, - thus forming a work based on the Program, and copy and distribute such - modifications or work under the terms of Section 1 above, provided that - you also meet all of these conditions: - - * a) You must cause the modified files to carry prominent notices stating - that you changed the files and the date of any change. - - * b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any part - thereof, to be licensed as a whole at no charge to all third parties - under the terms of this License. - - * c) If the modified program normally reads commands interactively when - run, you must cause it, when started running for such interactive - use in the most ordinary way, to print or display an announcement - including an appropriate copyright notice and a notice that there is - no warranty (or else, saying that you provide a warranty) and that - users may redistribute the program under these conditions, and - telling the user how to view a copy of this License. (Exception: if - the Program itself is interactive but does not normally print such - an announcement, your work based on the Program is not required to - print an announcement.) - - These requirements apply to the modified work as a whole. If identifiable - sections of that work are not derived from the Program, and can be - reasonably considered independent and separate works in themselves, then - this License, and its terms, do not apply to those sections when you - distribute them as separate works. But when you distribute the same - sections as part of a whole which is a work based on the Program, the - distribution of the whole must be on the terms of this License, whose - permissions for other licensees extend to the entire whole, and thus to - each and every part regardless of who wrote it. - - Thus, it is not the intent of this section to claim rights or contest - your rights to work written entirely by you; rather, the intent is to - exercise the right to control the distribution of derivative or - collective works based on the Program. - - In addition, mere aggregation of another work not based on the Program - with the Program (or with a work based on the Program) on a volume of a - storage or distribution medium does not bring the other work under the - scope of this License. - -3. You may copy and distribute the Program (or a work based on it, under - Section 2) in object code or executable form under the terms of Sections - 1 and 2 above provided that you also do one of the following: - - * a) Accompany it with the complete corresponding machine-readable source - code, which must be distributed under the terms of Sections 1 and 2 - above on a medium customarily used for software interchange; or, - - * b) Accompany it with a written offer, valid for at least three years, - to give any third party, for a charge no more than your cost of - physically performing source distribution, a complete machine- - readable copy of the corresponding source code, to be distributed - under the terms of Sections 1 and 2 above on a medium customarily - used for software interchange; or, - - * c) Accompany it with the information you received as to the offer to - distribute corresponding source code. (This alternative is allowed - only for noncommercial distribution and only if you received the - program in object code or executable form with such an offer, in - accord with Subsection b above.) - - The source code for a work means the preferred form of the work for - making modifications to it. For an executable work, complete source code - means all the source code for all modules it contains, plus any - associated interface definition files, plus the scripts used to control - compilation and installation of the executable. However, as a special - exception, the source code distributed need not include anything that is - normally distributed (in either source or binary form) with the major - components (compiler, kernel, and so on) of the operating system on which - the executable runs, unless that component itself accompanies the - executable. - - If distribution of executable or object code is made by offering access - to copy from a designated place, then offering equivalent access to copy - the source code from the same place counts as distribution of the source - code, even though third parties are not compelled to copy the source - along with the object code. - -4. You may not copy, modify, sublicense, or distribute the Program except as - expressly provided under this License. Any attempt otherwise to copy, - modify, sublicense or distribute the Program is void, and will - automatically terminate your rights under this License. However, parties - who have received copies, or rights, from you under this License will not - have their licenses terminated so long as such parties remain in full - compliance. - -5. You are not required to accept this License, since you have not signed - it. However, nothing else grants you permission to modify or distribute - the Program or its derivative works. These actions are prohibited by law - if you do not accept this License. Therefore, by modifying or - distributing the Program (or any work based on the Program), you - indicate your acceptance of this License to do so, and all its terms and - conditions for copying, distributing or modifying the Program or works - based on it. - -6. Each time you redistribute the Program (or any work based on the - Program), the recipient automatically receives a license from the - original licensor to copy, distribute or modify the Program subject to - these terms and conditions. You may not impose any further restrictions - on the recipients' exercise of the rights granted herein. You are not - responsible for enforcing compliance by third parties to this License. - -7. If, as a consequence of a court judgment or allegation of patent - infringement or for any other reason (not limited to patent issues), - conditions are imposed on you (whether by court order, agreement or - otherwise) that contradict the conditions of this License, they do not - excuse you from the conditions of this License. If you cannot distribute - so as to satisfy simultaneously your obligations under this License and - any other pertinent obligations, then as a consequence you may not - distribute the Program at all. For example, if a patent license would - not permit royalty-free redistribution of the Program by all those who - receive copies directly or indirectly through you, then the only way you - could satisfy both it and this License would be to refrain entirely from - distribution of the Program. - - If any portion of this section is held invalid or unenforceable under any - particular circumstance, the balance of the section is intended to apply - and the section as a whole is intended to apply in other circumstances. - - It is not the purpose of this section to induce you to infringe any - patents or other property right claims or to contest validity of any - such claims; this section has the sole purpose of protecting the - integrity of the free software distribution system, which is implemented - by public license practices. Many people have made generous contributions - to the wide range of software distributed through that system in - reliance on consistent application of that system; it is up to the - author/donor to decide if he or she is willing to distribute software - through any other system and a licensee cannot impose that choice. - - This section is intended to make thoroughly clear what is believed to be - a consequence of the rest of this License. - -8. If the distribution and/or use of the Program is restricted in certain - countries either by patents or by copyrighted interfaces, the original - copyright holder who places the Program under this License may add an - explicit geographical distribution limitation excluding those countries, - so that distribution is permitted only in or among countries not thus - excluded. In such case, this License incorporates the limitation as if - written in the body of this License. - -9. The Free Software Foundation may publish revised and/or new versions of - the General Public License from time to time. Such new versions will be - similar in spirit to the present version, but may differ in detail to - address new problems or concerns. - - Each version is given a distinguishing version number. If the Program - specifies a version number of this License which applies to it and "any - later version", you have the option of following the terms and - conditions either of that version or of any later version published by - the Free Software Foundation. If the Program does not specify a version - number of this License, you may choose any version ever published by the - Free Software Foundation. - -10. If you wish to incorporate parts of the Program into other free programs - whose distribution conditions are different, write to the author to ask - for permission. For software which is copyrighted by the Free Software - Foundation, write to the Free Software Foundation; we sometimes make - exceptions for this. Our decision will be guided by the two goals of - preserving the free status of all derivatives of our free software and - of promoting the sharing and reuse of software generally. - - NO WARRANTY - -11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY - FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN - OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES - PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER - EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED - WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE - ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH - YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL - NECESSARY SERVICING, REPAIR OR CORRECTION. - -12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING - WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR - REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR - DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL - DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM - (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED - INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF - THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR - OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. - -END OF TERMS AND CONDITIONS - -How to Apply These Terms to Your New Programs - -If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it free -software which everyone can redistribute and change under these terms. - -To do so, attach the following notices to the program. It is safest to -attach them to the start of each source file to most effectively convey the -exclusion of warranty; and each file should have at least the "copyright" -line and a pointer to where the full notice is found. - -one line to give the program's name and an idea of what it does. -Copyright (C) yyyy name of author - -This program is free software; you can redistribute it and/or modify it -under the terms of the GNU General Public License as published by the Free -Software Foundation; either version 2 of the License, or (at your option) -any later version. - -This program is distributed in the hope that it will be useful, but WITHOUT -ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or -FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for -more details. - -You should have received a copy of the GNU General Public License along with -this program; if not, write to the Free Software Foundation, Inc., 59 -Temple Place - Suite 330, Boston, MA 02111-1307, USA. - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this when -it starts in an interactive mode: - -Gnomovision version 69, Copyright (C) year name of author Gnomovision comes -with ABSOLUTELY NO WARRANTY; for details type 'show w'. This is free -software, and you are welcome to redistribute it under certain conditions; -type 'show c' for details. - -The hypothetical commands 'show w' and 'show c' should show the appropriate -parts of the General Public License. Of course, the commands you use may be -called something other than 'show w' and 'show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary.

Based loosely on + * original e100 driver, but better described as a munging of + * e100, e1000, eepro100, tg3, 8139cp, and other drivers. + * + * References: + * Intel 8255x 10/100 Mbps Ethernet Controller Family, + * Open Source Software Developers Manual, + * http://sourceforge.net/projects/e1000 + * + * + * Theory of Operation + * + * I. General + * + * The driver supports Intel(R) 10/100 Mbps PCI Fast Ethernet + * controller family, which includes the 82557, 82558, 82559, 82550, + * 82551, and 82562 devices. 82558 and greater controllers + * integrate the Intel 82555 PHY. The controllers are used in + * server and client network interface cards, as well as in + * LAN-On-Motherboard (LOM), CardBus, MiniPCI, and ICHx + * configurations. 8255x supports a 32-bit linear addressing + * mode and operates at 33Mhz PCI clock rate. + * + * II. Driver Operation + * + * Memory-mapped mode is used exclusively to access the device's + * shared-memory structure, the Control/Status Registers (CSR). All + * setup, configuration, and control of the device, including queuing + * of Tx, Rx, and configuration commands is through the CSR. + * cmd_lock serializes accesses to the CSR command register. cb_lock + * protects the shared Command Block List (CBL). + * + * 8255x is highly MII-compliant and all access to the PHY go + * through the Management Data Interface (MDI). Consequently, the + * driver leverages the mii.c library shared with other MII-compliant + * devices. + * + * Big- and Little-Endian byte order as well as 32- and 64-bit + * archs are supported. Weak-ordered memory and non-cache-coherent + * archs are supported. + * + * III. Transmit + * + * A Tx skb is mapped and hangs off of a TCB. TCBs are linked + * together in a fixed-size ring (CBL) thus forming the flexible mode + * memory structure. A TCB marked with the suspend-bit indicates + * the end of the ring. The last TCB processed suspends the + * controller, and the controller can be restarted by issue a CU + * resume command to continue from the suspend point, or a CU start + * command to start at a given position in the ring. + * + * Non-Tx commands (config, multicast setup, etc) are linked + * into the CBL ring along with Tx commands. The common structure + * used for both Tx and non-Tx commands is the Command Block (CB). + * + * cb_to_use is the next CB to use for queuing a command; cb_to_clean + * is the next CB to check for completion; cb_to_send is the first + * CB to start on in case of a previous failure to resume. CB clean + * up happens in interrupt context in response to a CU interrupt, or + * in dev->poll in the case where NAPI is enabled. cbs_avail keeps + * track of number of free CB resources available. + * + * Hardware padding of short packets to minimum packet size is + * enabled. 82557 pads with 7Eh, while the later controllers pad + * with 00h. + * + * IV. Recieve + * + * The Receive Frame Area (RFA) comprises a ring of Receive Frame + * Descriptors (RFD) + data buffer, thus forming the simplified mode + * memory structure. Rx skbs are allocated to contain both the RFD + * and the data buffer, but the RFD is pulled off before the skb is + * indicated. The data buffer is aligned such that encapsulated + * protocol headers are u32-aligned. Since the RFD is part of the + * mapped shared memory, and completion status is contained within + * the RFD, the RFD must be dma_sync'ed to maintain a consistent + * view from software and hardware. + * + * Under typical operation, the receive unit (RU) is start once, + * and the controller happily fills RFDs as frames arrive. If + * replacement RFDs cannot be allocated, or the RU goes non-active, + * the RU must be restarted. Frame arrival generates an interrupt, + * and Rx indication and re-allocation happen in the same context, + * therefore no locking is required. If NAPI is enabled, this work + * happens in dev->poll. A software-generated interrupt is gen- + * erated from the watchdog to recover from a failed allocation + * senario where all Rx resources have been indicated and none re- + * placed. + * + * V. Miscellaneous + * + * VLAN offload support of tagging, stripping and filtering is not + * supported, but driver will accommodate the extra 4-byte VLAN tag + * for processing by upper layers. Tx/Rx Checksum offloading is not + * supported. Tx Scatter/Gather is not supported. Jumbo Frames is + * not supported. + * + * NAPI support is enabled with CONFIG_E100_NAPI. + * + * MagicPacket(tm) WoL support is enabled/disabled via ethtool. + */ + +// TODO list +// - deep power down on link down enable - GEN_CONTROL_REG +// - ICH 10Mb/half Tx s/w workaround +// - Need to cleanup kcompat.h + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include + + +#define DRV_NAME "e100" +#define DRV_VERSION "3.0.0_dev8" +#define DRV_DESCRIPTION "Intel(R) PRO/100 Network Driver" +#define DRV_COPYRIGHT "Copyright(c) 1999-2003 Intel Corporation" +#define PFX DRV_NAME ": " + +#define E100_WATCHDOG_PERIOD 2 * HZ +#define E100_NAPI_WEIGHT 16 + +MODULE_DESCRIPTION(DRV_DESCRIPTION);
