   38     if you have a function that takes const arguments and then
   39     e.g. tries to copy StrCmp, gcc will give you warnings about those
   40     calls, and the warnings are right.  These clutter up other things
   41     you might miss that you should be more concered about.
   42 
   43     You could work around it through vigorous typecasting
   44     to non-const types, but why should you have to? All of these
   45     functions are regorously defined as not changing their input
   46     - it is const, and should be marked as such.

   85     Disable MMX and SSE
   86     
   87     GCC 4.8.0 adds some optimizations that will use movups/movaps (and use
   88     %xmm* registers) when they're faster, and of course that won't work at
   89     all since UEFI firmwares aren't guaranteed to initialize the mmx/sse
   90     instructions.
   91     
   92     This will be even more annoying, since most UEFI firmwares don't
   93     initialize the #DE or #UD trap handlers, and your backtrace will be a
   94     random path through uninitialized memory, occasionally including
   95     whatever address the IDT has for #UD, but also addresses like "0x4" and
   96     "0x507" that you don't normally expect to see in your call path.

  103     bug in make 3.82 expand to odd values
  104     
  105     Some Makefiles tickle a bug in make 3.82 that cause libefi.a
  106     and libgnuefi.a dependencies to expand to the odd values:
  107     
  108     libefi.a: boxdraw.o) smbios.o) ...
  109     libgnuefi.a(reloc_x86_64.o:
  110     
  111     The patch replaces libgnuefi.a($(OBJS)) & libefi.a($(OBJS))
  112     with an equivalent expansion that should work with any make
  113     that supports $(patsubst).

  141     Instead of asking developers to explicitly pass the number of

  155 
  156     fix parameter-passing corruption on x86_64 for >= 5 args
  157     
  158     On x86_64 without HAVE_USE_MS_ABI support, uefi_call_wrapper() is a
  159     variadic function. Parameters >=5 are copied to the stack and, when
  160     passed small immediate values (and possibly other parameters), gcc
  161     would emit a movl instruction before calling uefi_call_wrapper(). As a
  162     result, only the lower 32b of these stack values are significant, the
  163     upper 32b potentially contain garbage. Considering that
  164     uefi_call_wrapper() assumes these arguments are clean 64b values
  165     before calling the efi_callX() trampolines, the latter may be passed
  166     garbage. This makes calling functions like
  167     EFI_PCI_IO_PROTOCOL.Mem.Read()/Write() or BS->OpenProtocol() quite
  168     unreliable.
  169     
  170     This patch fixes this by turning uefi_call_wrapper() into a macro that
  171     allows to expose the efi_callX() trampoline signatures to the callers,
  172     so that gcc can know upfront that it has to pass all arguments to
  173     efi_callX() as clean 64b values (eg. movq for immediates). The
  174     _cast64_efi_callX macros are just here to avoid a gcc warning, they do
  175     nothing otherwise.

  180     Date:   Wed May 15 15:26:16 2013 -0400
  181 
  182     - Removes the ElfW() macro usage from reloc_ia32.c and reloc_x86_64.c. These
  183     macros only exist in link.h on Linux. On FreeBSD, the equivalent macro is
  184     __ElfN(). But the macro usage is redundant. You're only going to compile the
  185     ia32 file for IA32 binaries and the x86_64 file for X64 binaries. If you had
  186     just one file built for both cases, then using the macro might make more
  187     sense.
  188     
  189     - Removes the "#define foo_t efi_foo_t" macros from reloc_ia32.c and
  190     reloc_x86_64.c.
  191     
  192     - Modifies inc/x86_64/efibind.h and inc/ia32/efibind.h to use the new
  193     definitions for uint64_t, int64_t and int8_t. The 64-bit types are now defined
  194     as:
  195     
  196             typedef int __attribute__((__mode__(__DI__)))           int64_t;
  197             typedef unsigned int __attribute__((__mode__(__DI__)))  uint64_t;
  198     
  199     This removes the conflict between the host types dragged in by elf.h and the
  200     type definitions in efibind.h that made the #define foo_t efi_foo_t" hack
  201     necessary. Also, int8_t is now defined as signed char instead of just char
  202     (assuming char == signed char is apparently not good enough).
  203     
  204     - Also modifies these files to use stdint.h instead of stdint-gcc.h. It's
  205     unclear if this is completely correct, but stdint-gcc.h is not present with
  206     all GCC installs, and if you use -std=c99 or later you will force this case to
  207     be hit. This also can break clang, which doesn't have a stdint-gcc.h at all.
  208     
  209     - Removes the #include of <link.h> from reloc_ia32.c and reloc_x86_64.c (since
  210     with the previous changes it's not needed anymore).
  211     
  212     - Places the #include of <elf.h> after #include <efi>/#include <efilib.h> so
  213     that we know the types will always be defined properly, in case you build on a
  214     system where <elf.h> doesn't automatically pull in the right header files to
  215     define all the needed types. (This actually happens on VxWorks. It's harmless
  216     elsewhere. If you don't care about VxWorks, you can leave this out.)
  217     
  218     - Modifies setjmp_ia32.S and setjmp_x86_64.S so to change "function" to
  219     @function. The clang compiler doesn't like the former. Clang and GCC both like
  220     the latter.
  221     
  222     - Modifles Make.defaults so that if ARCH is detected as "amd64," it's changed
  223     to "x86_64." It happens that uname -m on 64-bit FreeBSD reports the former
  224     rather than the latter, which breaks the build. This may also be the case on
  225     some other OSes. There's a way to force uname(1) to return x86_64 as the
  226     machine type, but this way is a little friendlier.
  227     
  228     - Creates gnuefi/elf_ia32_fbsd_efi.lds which specifies the object file type as
  229     elf-ia32-freebsd. This is required for building on FreeBSD/i386, not just
  230     FreeBSD/amd64.
  231     
  232     - Modifies apps/Makefile to always use
  233     $(TOPDIR)/gnuefi/elf_$(ARCH)_fbsd_efi.lds when building on either 32-bit or
  234     64-bit FreeBSD instead of just for the x86_64 case.
  235     
  236     - Changed LDFLAGS in Make.defaults to include --no-undefined. This will cause
  237     linking to fail if there are any unsatisfied symbols when creating foo.so
  238     during any of the app builds, as opposed to just silently succeeding and
  239     producing an unusable binary.
  240     
  241     - Changed CFLAGS to include -ffreestanding -fno-stack-protector -fno-stack-
  242     check. This prevents clang from inserting a call to memset() when compiling
  243     the RtZeroMem() and RtSetMem() routines in lib/runtime/efirtlib.c and guards
  244     against the native compiler in some Linux distros from adding in stack
  245     checking code which relies on libc help that isn't present in the EFI runtime
  246     environment.
  247     
  248     This does the following:
  249     
  250     - Cleans up the ia32 and x86-64 relocation code a bit (tries to break the
  251     dependency between the host ELF headers and the EFI runtime environment)
  252     - Avoids the dependency on stdint-gcc.h which may not always be available
  253     - Allows GNU EFI to build out of the box on both FreeBSD/i386 and
  254     FreeBSD/amd64
  255     - Allows GNU EFI to build out of the box with either GCC or clang on
  256     FreeBSD/i386 and FreeBSD/amd64 9.0 and later.
  257     - Makes things a little easier to port to VxWorks
  258     - Avoids creating un-runable binaries with unresolved symbol definitions
  259     (which can be very confusing to debug)

  273 	* Change from Peter Jones <pjones@redhat.com>
  274 	  - Previously we were incorrectly passing 3 functions with
  275             the System V ABI to UEFI functions as EFI ABI functions.
  276             Mark them as EFIAPI so the compiler will (in our new
  277             GNU_EFI_USE_MS_ABI world) use the correct ABI.
  278           - These need to be EFIAPI functions because in some cases
  279             they call ST->ConOut->OutputString(), which is an EFIAPI
  280             function. (Which means that previously in cases that 
  281             needed "cdecl", these didn't work right.)
  282           - If the compiler version is new enough, and GNU_EFI_USE_MS_ABI
  283             is defined, use the function attribute ms_abi on everything
  284             defined with "EFIAPI".  Such calls will no longer go through
  285             efi_call*, and as such will be properly type-checked.
  286           - Honor PREFIX and LIBDIR correctly when passed in during the build.
  287           - Add machine type defines for i386, arm/thumb, ia64, ebc, x86_64.
  288           - __STDC_VERSION__ never actually gets defined unless there's a
  289             --std=... line.  So we were accidentally defining lots of c99
  290             types ourself. Since it's 2012, use --std=c11 where appropriate,
  291             and if it's defined and we're using gcc, actually include gcc's
  292             stdint definitions.
  293           - New test application added: route80h. This is a test program
  294             for PciIo.  It routes ioport 80h on ICH10 to PCI. This is also
  295             useful on a very limited set of hardware to enable use of
  296             a port 80h debug card.
  297           - New test applcation added: modelist. This lists video modes

  317             which is in part the fault of gummiboot, but happens only
  318             because the stack gets screwed. x86_64 EFI already aligns the
  319             stack, so there's no need for so much code to find a proper
  320             alignment, we always need to shift by 8 anyway.

  332 	    regarding physical disk layout, including alingment offset at the
  333 	    beginning of the disk ("LowestAlignedLba"), logical block size
  334 	    ("LogicalBlocksPerPhysicalBlock"), and optimal block transfer size
  335 	    ("OptimalTransferLengthGranularity").

  339 	* Change from Matt Fleming <matt.fleming@intel.com>
  340 	  -  The .reloc section is now 4096-byte boundary for x86_64.
  341 	     Without this patch the .reloc section will not adhere to
  342 	     the alignment value in the FileAlignment field (512 bytes by
  343 	     default) of the PE/COFF header. This results in a signed
  344 	     executable failing to boot in a secure boot environment.
  345 	* Release 3.0q

  367 	* Changes from Peter Jones <pjones@redhat.com>
  368 	  - Add ifdefs for ia64 to mirror ia32 and x86-64 so that
  369 	    one can build with GCC.
  370 	  - Add headers for PciIo.
  371 	  - Add the UEFI 2.x bits for EFI_BOOT_SERVICES

  442 	* release 3.0a
  443 	* modified both IA-64 and IA-32 loader scripts to add support for the
  444 	  new .rodata sections names (such as rodata.str2.8). Required
  445 	  for new versions of gcc3.x.
  446 
  447 2001-06-20  Stephane Eranian <eranian@hpl.hp.com>
  448 	* release 3.0
  449 	* split gnu-efi package in two different packages: the libary+include+crt and the bootloader.
  450 	* removed W2U() hack and related files to get from wide-char to unicode. 
  451 	* Use -fshort-wchar option for unicode.
  452 	* restructured Makefiles now install under INSTALLROOT.
  453 
  454 2001-04-06  Stephane Eranian <eranian@hpl.hp.com>
  455 
  456 	* incorporated patches from David and Michael Johnston at Intel
  457 	  to get the package to compile for IA-32 linux target.
  458 
  459 	* Fixed ELILO to compile for Ia-32 (does not execute yet, though):
  460 	  Makefile and start_kernel() function.
  461 
  462 2001-04-06  Andreas Schwab <schwab@suse.de>
  463 
  464 	* Fixed config.c  to
  465 	  get the timeout directive to do something. implemented the global
  466 	  root= directive.
  467 
  468 	* Fix the efi_main() to deal with the -C option properly
  469 
  470 2001-04-05  Stephane Eranian <eranian@hpl.hp.com>
  471 
  472 	* update efi library to latest EFI toolkit 1.02 as distributed
  473 	  by Intel. Fixed header + library files to compile with GCC
  474 
  475 	* merged ELI and LILO (as of gnu-efi-1.1) together, mostly
  476 	  taking the config file feature of ELI.
  477 
  478 	* renamed LILO to ELILO to make the distinction
  479 
  480 	* restructured code to make it easier to understand and maintain
  481 
  482 	* fixed FPSWA driver checking and loading: we try all possible
  483 	  files and let the driver itself figure out if it is the most
  484 	  recent.
  485 	* added support for compression (gzip) but keep support for plain
  486 	  ELF image. ELILO autodetects the format
  487 
  488 	* change the way the kernel is invoked. Now we call it in 
  489 	  physical memory mode. This breaks the dependency between the
  490 	  kernel code and the loader. No more lilo_start.c madness.
  491 
  492 	* changed the way the boot_params are passed. We don't use the 
  493 	  ZERO_PAGE_ADDR trick anymore. Instead we use EFI runtime memory.
  494 	  The address of the structure is passed to the kernel in r28
  495 	  by our convention.
  496 
  497 	* released as gnu-efi-2.0
  498 
  499 2001-04-03  David Mosberger  <davidm@hpl.hp.com>
  500 
  501 	* gnuefi/reloc_ia32.c (_relocate): Change return type from "void"
  502 	to "int".  Return error status if relocation fails for some
  503 	reason.
  504 
  505 	* gnuefi/elf_ia32_efi.lds: Drop unneeded ".rel.reloc" section.
  506 
  507 	* gnuefi/crt0-efi-ia32.S (_start): Exit if _relocate() returns with
  508 	non-zero exit status.
  509 
  510 	* inc/ia32/efibind.h [__GNUC__]: Force 8-byte alignment for 64-bit
  511 	types as that is what EFI appears to be expecting, despite the
  512 	"#pragma pack()" at the beginning of the file!
  513 
  514 2001-03-29  David Mosberger  <davidm@hpl.hp.com>
  515 
  516 	* gnuefi/reloc_ia32.c: Add a couple of defines to work around
  517 	libc/efilib collision on uint64_t et al.
  518 	(_relocate): Use ELF32_R_TYPE() instead of ELFW(R_TYPE)().
  519 
  520 	* gnuefi/crt0-efi-ia32.S (dummy): Add a dummy relocation entry.
  521 
  522 2001-03-29  David Mosberger  <davidm@hpl.hp.com>

  525         libc/efilib collision on uint64_t et al.
  526         (_relocate): Use ELF32_R_TYPE() instead of ELFW(R_TYPE)().
  527 
  528         * gnuefi/crt0-efi-ia32.S (dummy): Add a dummy relocation entry.
  529 
  530 2000-10-26  David Mosberger  <davidm@hpl.hp.com>
  531  
  532  	* gnuefi/elf_ia64_efi.lds: Mention .rela.sdata.
  533  
  534  	* Make.defaults (CFLAGS): Remove -nostdinc flags so we can pick
  535  	up the C compiler's stdarg.h.
  536  
  537  	* inc/stdarg.h: Remove this file.  It's not correct for gcc (nor
  538  	most other optimizing compilers).
  539 
  540 2000-10-10  Stephane Eranian <eranian@hpl.hp.com>
  541 
  542 	* cleaned up the error message and printing of those.
  543 	* added support to load the FPSWA from a file in case support is not
  544 	  present in the firmware already
  545 	* fixed split_args() to do the right thing when you have leading spaces
  546 	  before kernel name
  547 	* changed the argify() function to rely on \0 instead of LoadOptionSize
  548 	  as the field seems to be broken with current firmware
  549 	* bumped version to 1.0
  550 
  551 2000-10-04  David Mosberger  <davidm@hpl.hp.com>
  552  
  553 	* gnuefi/reloc_ia64.S: Reserve space for up to 750 function descriptors.
  554 
  555 	* gnuefi/elf_ia64_efi.lds: Add .sdata section for small data and
  556 	put __gp in the "middle" of it.
  557 
  558 	* gnuefi/crt0-efi-ia64.S (_start): Use movl/add to load
  559 	gp-relative addresses that could be out of the range of the addl
  560 	offset.
  561 	* gnuefi/reloc_ia64.S (_relocate): Ditto.
  562 
  563 	* apps/Makefile: Remove standard rules and include Make.rules instead.
  564 	* lilo/Makefile: Ditto.
  565 
  566 	* Make.rules: New file.
  567

  573 	* got rid of #ifdef LILO_DEBUG and uses macro instead
  574 	* fix a few extra memory leaks in create_boot_params()
  575 	* added exit capability just before starting the kernel
  576 
  577 2000-06-22  David Mosberger  <davidm@hpl.hp.com>
  578 
  579 	* gnuefi/elf_ia64_efi.lds: Add .srodata, .ctors, .IA64.unwind,
  580 	.IA64.unwind_info to .data section and .rela.ctors to .rela
  581 	section.
  582 
  583 2000-04-03  David Mosberger  <davidm@hpl.hp.com>
  584 
  585 	* lilo/lilo.c (LILO_VERSION): Up version number to 0.9.
  586 
  587 	* gnuefi/elf_ia64_efi.lds: Include .IA_64.unwind and
  588 	.IA_64.unwind_info in .data segment to avoid EFI load error
  589 	"ImageAddress: pointer outside of image" error due to the .dynsym
  590 	relocations against these sections.
  591 
  592 	* ChangeLog: Moved from lilo/ChangeLogs.
  593 
  594 	* gnuefi/reloc_ia64.S: fixed typo: .space directive had constant
  595 	100 hardcoded instead of using MAX_FUNCTION_DESCRIPTORS
  596 	macro. Duh.
  597
