* [libc] Add inline assembly implementation of flsl() using BSR instructionMichael Brown2014-04-241-0/+31
| | | | Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [vesafb] Add VESA frame buffer consoleMichael Brown2013-11-281-0/+1
| | | | | | | | | | | The VESA frame buffer console uses the VESA BIOS extensions (VBE) to enumerate video modes, selects an appropriate mode, and then hands off to the generic frame buffer code. The font is extracted from the VGA BIOS, avoiding the need to provide an external font file. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [settings] Expose CPUID instruction via settings mechanismMichael Brown2013-08-072-0/+26
| | | | | | | | | | | | | | | | | | | | | | | Allow CPUID values to be read using the syntax ${cpuid/<register>.<function>} For example, ${cpuid/2.0x80000001} will give the value of %ecx after calling CPUID with %eax=0x80000001. Values for <register> are encoded as %eax=0, %ebx=1, %ecx=2, %edx=3. The numeric encoding is more sophisticated than described above, allowing for settings such as the CPU model (obtained by calling CPUID with %eax=0x80000002-0x80000004 inclusive and concatenating the values returned in %eax:%ebx:%ecx:%edx). See the source code for details. The "cpuvendor" and "cpumodel" settings provide easy access to these more complex CPUID settings. This functionality is intended to complement the "cpuid" command, which allows for testing individual CPUID feature bits. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [tcpip] Add faster algorithm for calculating the TCP/IP checksumMichael Brown2012-06-281-0/+5
| | | | | | | | | The generic TCP/IP checksum implementation requires approximately 10 CPU clocks per byte (as measured using the TSC). Improve this to approximately 0.5 CPU clocks per byte by using "lodsl ; adcl" in an unrolled loop. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [tcpip] Allow for architecture-specific TCP/IP checksum routinesMichael Brown2012-06-271-0/+12
| | | | | | | Calculating the TCP/IP checksum on received packets accounts for a substantial fraction of the response latency. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [crypto] Add big-integer library for RSA calculationsMichael Brown2012-03-141-0/+318
| | | | | | | | | | | | | | RSA requires modular exponentiation using arbitrarily large integers. Given the sizes of the modulus and exponent, all required calculations can be done without any further dynamic storage allocation. The x86 architecture allows for efficient large integer support via inline assembly using the instructions that take advantage of the carry flag (e.g. "adcl", "rcrl"). This implemention is approximately 80% smaller than the (more generic) AXTLS implementation. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [linux] Avoid unused-but-set variable warning in gcc 4.6Thomas Miletich2011-03-281-2/+2
| | | | | | | | | Temporary modification to prevent valgrind.h from breaking compilation with gcc 4.6. When this problem is fixed upstream, a new and unmodified copy of valgrind.h should be imported.

* [string] Use 64-bit registers in assembly memswap() on x86_64Joshua Oreman2010-08-011-4/+4
| | | | | | | | | An assembly version of memswap() is in an x86 word-length-agnostic header file, but it used 32-bit registers to store pointers, leading to memory errors responding to ARP queries on 64-bit systems.

* [build] Rename gPXE to iPXEMichael Brown2010-04-204-9/+9
| | | | | | | | | | | Access to the gpxe.org and etherboot.org domains and associated resources has been revoked by the registrant of the domain. Work around this problem by renaming project from gPXE to iPXE, and updating URLs to match. Also update README, LOG and COPYRIGHTS to remove obsolete information. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [legal] Add a selection of FILE_LICENCE declarationsMichael Brown2009-05-185-0/+10
| | | | | Add FILE_LICENCE declarations to almost all files that make up the various standard builds of gPXE.
* [x86_64] Add support for compilation as an x86_64 binaryMichael Brown2008-12-055-0/+551
Currently the only supported platform for x86_64 is EFI. Building an EFI64 gPXE requires a version of gcc that supports __attribute__((ms_abi)). This currently means a development build of gcc; the feature should be present when gcc 4.4 is released. In the meantime; you can grab a suitable gcc tree from git://git.etherboot.org/scm/people/mcb30/gcc/.git
