* [build] Update build system for Syslinux 6.xChristian Hesse2013-11-151-0/+8
| | | | | | | | | Syslinux 6.x places its files into a bios subdirectory, and requires that a ldlinux.c32 module be included within the ISO image. Add the relevant search paths for isolinux.bin, and include the file ldlinux.c32 within the ISO image if it exists. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [libc] Redefine low 8 bits of error code as "platform error code"Michael Brown2013-04-191-0/+5
| | | | | | | | | | The low 8 bits of an iPXE error code are currently defined as the closest equivalent PXE error code. Generalise this scheme to platforms other than PC-BIOS by extending this definition to "closest equivalent platform error code". This allows for the possibility of returning meaningful errors via EFI APIs. Signed-off-by: Michael Brown <mcb30@ipxe.org>

| | | | | | | | | | | The UNDI ROM header does contain a checksum byte. Apparently no-one cares about this, since iPXE has left it as zero for years without anyone noticing.

* [romprefix] Report a pessimistic runtime size estimateMichael Brown2012-07-233-1/+88
| | | | | | | | | | | | | | | | PCI3.0 allows us to report a "runtime size" which can be smaller than the actual ROM size. On systems that support PMM our runtime size will be small (~2.5kB), which helps to conserve the limited option ROM space. However, there is no guarantee that the PMM allocation will succeed, and so we need to report the worst-case runtime size in the PCI header. Move the "shrunk ROM size" field from the PCI header to a new "iPXE ROM header", allowing it to be accessed by ROM-manipulation utilities such as disrom.pl. Reported-by: Anton D.

* [util] Avoid compiler warning on gcc 4.6Michael Brown2012-07-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 196751c ("[build] Enable warnings when building utilities") revealed a previously hidden compiler warning in util/nrv2b.c regarding an out-of-bounds array subscript in the code #if defined(SWD_BEST_OFF) if (s->best_pos[2] == 0) s->best_pos[2] = key + 1; #endif where best_pos[] is defined by #define SWD_BEST_OFF 1 #if defined(SWD_BEST_OFF) unsigned int best_off[ SWD_BEST_OFF ]; unsigned int best_pos[ SWD_BEST_OFF ]; #endif With SWD_BEST_OFF set to 1, it can be proven that all code paths referring to s->best_off[] and s->best_pos[] will never be executed, with the exception of the two lines above. Since these two lines alone can have no effect on execution, we can safely undefine SWD_BEST_OFF. Verified by comparing md5sums of bin/undionly.kpxe before and after the change.

| | | | | | | | | | | | | The header of a .mrom image declares its length to be only a few kilobytes; the remainder is accessed via a sideband mechanism.

* [console] Try to avoid problems caused by keycode 86Michael Brown2011-03-161-4/+15
| | | | | | | | | | | | | | | | | The "us" keyboard layout contains a mapping for keycode 86 (which seems not to correspond to any physical key on many US keyboards) to the ASCII character '<'. This mapping causes conflicts with the mapping for keycode 51, which also maps (with shift) to '<'. Change the keyboard mapping generator to choose the lowest keycode for each ASCII character as indicating the relevant mapping to use, on the basis that a lower keycode roughly indicates a "more normal" key. On a German keyboard, which has keys for both keycode 51 and keycode 86 present, this causes '<' to be remapped to ';', which is a closer match to typical user expectations.

| | | | | | | | | | | | | | | | | | | | | | | | | Enhance the information collected by the function recorder to include the call site and entry/exit counts. This allows fnrec.pl to produce a call tree such as: step (from core/getkey.c:46 = 0x17e90) { ref_increment (from core/process.c:93 = 0x73ec) { } net_step (from core/process.c:96 = 0x73f1) { net_poll (from net/netdevice.c:741 = 0xbce6) { netdev_poll (from net/netdevice.c:700 = 0xbc58) { } netdev_rx_dequeue (from net/netdevice.c:709 = 0xbc65) { } } } ref_decrement (from core/process.c:96 = 0x73f9) { } } Note that inlined functions are reported, confusingly, as extra calls to the *containing* function. Minimise this confusion by adding the attribute "no_instrument_function" to all functions declared as inline. (Static functions that have been inlined autonomously by gcc will still be problematic, but these are far fewer in number.) Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [efi] Fix the 32-bit version of elf2efi64Geoff Lywood2010-07-211-10/+10
| | | | | | | | | | | | | | | | | | | Currently, if elf2efi.c is compiled using a 32-bit HOST_CC, then the resulting elf2efi64 binary will generate 32-bit EFI binaries instead of 64-bit EFI binaries. The problem is that elf2efi.c uses the MDE_CPU_* definitions to decide whether to output a 32-bit or 64-bit PE binary. However, MDE_CPU_* gets defined in ProcessorBind.h, depending on the compiler's target architecture. Overriding them on the command line doesn't work in the expected way, and you can end up in cases where both MDE_CPU_IA32 and MDE_CPU_X64 are defined. Fix by using a separate definition, EFI_TARGET_IA32/EFI_TARGET_X64, which is specified only on the command line.

* [romprefix] Add .mrom format, allowing loading of large ROMsMichael Brown2010-04-251-1/+2
| | | | | | | | | | | | | | | | | | | | | Add an infrastructure allowing the prefix to provide an open_payload() method for obtaining out-of-band access to the whole iPXE image. Add a mechanism within this infrastructure that allows raw access to the expansion ROM BAR by temporarily borrowing an address from a suitable memory BAR on the same PCI card. For cards that have a memory BAR that is at least as large as their expansion ROM BAR, this allows large iPXE ROMs to be supported even on systems where PMM fails, or where option ROM space pressure makes it impossible to use PMM shrinking. The BIOS sees only a stub ROM of approximately 3kB in size; the remainder (which can be well over 64kB) is loaded only at the time iPXE is invoked. As a nice side-effect, an iPXE .mrom image will continue to work even if its PMM-allocated areas are overwritten between initialisation and invocation. Signed-off-by: Michael Brown <mcb30@ipxe.org>

| | | | | | | | | | | The only remaining useful function of makerom.pl is to correct the ROM and PnP checksums; the PCI IDs are set at link time, and padding is performed using padimg.pl. Option::ROM already provides a facility for correcting the checksums, so we may as well just use this instead. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [prefix] Add .text16.early sectionMichael Brown2010-04-201-5/+56
| | | | | | | | | | | | | Add a section .text16.early which is always kept inline with the prefix. This will allow for some code sharing between the .prefix and .text16 sections. Note that the simple solution of just prepending the .prefix section to the .text16 section will not work, because a bug in Wyse Streaming Manager server (WLDRM13.BIN) requires us to place a dummy PXENV+ entry point at the start of .text16.

* [romprefix] Remove .xrom prefixMichael Brown2010-04-201-18/+12Star
| | | | | | | | | | | | | | | The .xrom prefix provides an experimental mechanism for loading ROM images greater than 64kB in size by mapping the expansion ROM BAR in at a hopefully-unused address. This is unreliable, and potentially dangerous. In particular, there is no guarantee that any PCI bridges between the CPU and the device will respond to accesses for the "unused" memory region that is chosen, and it is possible that the process of scanning for the "unused" memory region may end up issuing reads to other PCI devices. If this ends up trampling on a register with read side-effects belonging to an unrelated PCI device, this may cause undefined behaviour. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [prefix] Add .xrom prefix for a ROM that loads itself by PCI accessesJoshua Oreman2010-01-201-12/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The standard option ROM format provides a header indicating the size of the entire ROM, which the BIOS will reserve space for, load, and call as necessary. However, this space is strictly limited to 128k for all ROMs. gPXE ameliorates this somewhat by reserving space for itself in high memory and relocating the majority of its code there, but on systems prior to PCI3 enough space must still be present to load the ROM in the first place. Even on PCI3 systems, the BIOS often limits the size of ROM it will load to a bit over 64kB. These space problems can be solved by providing an artificially small size in the ROM header: just enough to let the prefix code (at the beginning of the ROM image) be loaded by the BIOS. To the BIOS, the gPXE ROM will appear to be only a few kilobytes; it can then load the rest of itself by accessing the ROM directly using the PCI interface reserved for that task. There are a few problems with this approach. First, gPXE needs to find an unmapped region in memory to map the ROM so it can read from it; this is done using the crude but effective approach of scanning high memory (over 0xF0000000) for a sufficiently large region of all-ones (0xFF) reads. (In x86 architecture, all-ones is returned for accesses to memory regions that no mapped device can satisfy.) This is not provably valid in all situations, but has worked well in practice. More importantly, this type of ROM access can only work if the PCI ROM BAR exists at all. NICs on physical add-in PCI cards generally must have the BAR in order for the BIOS to be able to load their ROM, but ISA cards and LAN-on-Motherboard cards will both fail to load gPXE using this scheme. Due to these uncertainties, it is recommended that .xrom only be used when a regular .rom image is infeasible due to crowded option ROM space. However, when it works it could allow loading gPXE images as large as a flash chip one could find - 128kB or even higher. Signed-off-by: Marty Connor <mdc@etherboot.org>
