DragonStub/gnu-efi-3.0/ChangeLog

2013-05-02 Nigel Croxon <nigel.croxon@hp.com>
	* Chnage from Matt Fleming <matt.fleming@intel.com>
	  - Preparation for adding the networking protocol definitions.
	    Add the service binding protocol.

2013-02-21 Nigel Croxon <nigel.croxon@hp.com>
	* Change from Peter Jones <pjones@redhat.com>
	  - Previously we were incorrectly passing 3 functions with
            the System V ABI to UEFI functions as EFI ABI functions.
            Mark them as EFIAPI so the compiler will (in our new
            GNU_EFI_USE_MS_ABI world) use the correct ABI.
          - These need to be EFIAPI functions because in some cases
            they call ST->ConOut->OutputString(), which is an EFIAPI
            function. (Which means that previously in cases that 
            needed "cdecl", these didn't work right.)
          - If the compiler version is new enough, and GNU_EFI_USE_MS_ABI
            is defined, use the function attribute ms_abi on everything
            defined with "EFIAPI".  Such calls will no longer go through
            efi_call*, and as such will be properly type-checked.
          - Honor PREFIX and LIBDIR correctly when passed in during the build.
          - Add machine type defines for i386, arm/thumb, ia64, ebc, x86_64.
          - __STDC_VERSION__ never actually gets defined unless there's a
            --std=... line.  So we were accidentally defining lots of c99
            types ourself. Since it's 2012, use --std=c11 where appropriate,
            and if it's defined and we're using gcc, actually include gcc's
            stdint definitions.
          - New test application added: route80h. This is a test program
            for PciIo.  It routes ioport 80h on ICH10 to PCI. This is also
            useful on a very limited set of hardware to enable use of
            a port 80h debug card.
          - New test applcation added: modelist. This lists video modes
            the GOP driver is showing us.
	* Change from Finnbarr Murphy
          - https://sourceforge.net/p/gnu-efi/feature-requests/2/
            Please add the following status codes to <efierr.h>
            EFI_INCOMPATIBLE_VERSION 25
            EFI_SECURITY_VIOLATION 26 
            EFI_CRC_ERROR 27 
            EFI_END_OF_MEDIA 28 
            EFI_END_OF_FILE 31 
            EFI_INVALID_LANGUAGE 32 
            EFI_COMPROMISED_DATA 33
	* Change from SourceForge.net Bug report
          - https://sourceforge.net/p/gnu-efi/bugs/5/
            BufferSize is a UINT64 *. The file shipped with GNU EFI is from
            1998 whereas the latest one is from 2004. I suspect Intel changed
            the API in order handle 64-bit systems.
        * Change from Felipe Contreras <felipe.contreras@gmail.com>
          - The current code seems to screw the stack at certain points.
            Multiple people have complained that gummiboot hangs right away,
            which is in part the fault of gummiboot, but happens only
            because the stack gets screwed. x86_64 EFI already aligns the
            stack, so there's no need for so much code to find a proper
            alignment, we always need to shift by 8 anyway.
        * Change from A. Steinmetz
          - https://sourceforge.net/p/gnu-efi/patches/1/
            The patch prepares for elilo to support uefi pxe over ipv6
            See uefi spec 2.3.1 errata c page 963 as reference.
            Verfied on an ASUS Sabertooth X79 BIOS Rev. 2104 system which
            is able to do an IPv6 UEFI PXE boot.
	* Release 3.0t

2012-09-21 Nigel Croxon <nigel.croxon@hp.com>
	* Change from Peter Jones <pjones@redhat.com>
	  - EFI Block I/O protocol versions 2 and 3 provide more information
	    regarding physical disk layout, including alingment offset at the
	    beginning of the disk ("LowestAlignedLba"), logical block size
	    ("LogicalBlocksPerPhysicalBlock"), and optimal block transfer size
	    ("OptimalTransferLengthGranularity").
	* Release 3.0r

2012-04-30 Nigel Croxon <nigel.croxon@hp.com>
	* Change from Matt Fleming <matt.fleming@intel.com>
	  -  The .reloc section is now 4096-byte boundary for x86_64.
	     Without this patch the .reloc section will not adhere to
	     the alignment value in the FileAlignment field (512 bytes by
	     default) of the PE/COFF header. This results in a signed
	     executable failing to boot in a secure boot environment.
	* Release 3.0q

2011-12-12 Nigel Croxon <nigel.croxon@hp.com>
        * Changes from Fenghua Yu <fenghua.yu@intel.com>

        * Release 3.0p

2011-11-15 Nigel Croxon <nigel.croxon@hp.com>
        * Changes from Darren Hart <dvhart@linux.intel.com>
          - Conditionally assign toolchain binaries to allow overriding them.
          - Force a dependency on lib for gnuefi.
        * Release 3.0n

2011-08-23 Nigel Croxon <nigel.croxon@hp.com>
        * Changes from Peter Jones <pjones@redhat.com>
          - Add guarantee 16-byte stack alignment on x86_64.
          - Add routine to make callbacks work.
          - Add apps/tcc.efi to test calling convention.
        * Release 3.0m

2011-07-22 Nigel Croxon <nigel.croxon@hp.com>
	* Changed Makefiles from GPL to BSD.
	* Changes from Peter Jones <pjones@redhat.com>
	  - Add ifdefs for ia64 to mirror ia32 and x86-64 so that
	    one can build with GCC.
	  - Add headers for PciIo.
	  - Add the UEFI 2.x bits for EFI_BOOT_SERVICES
	  - Add an ignore for .note.GNU-stack section in X86-64 linker maps.

	  created by gcc-3.3. Patch provided by Andreas Schwab from Suse.

2003-06-20  Stephane Eranian <eranian@hpl.hp.com>
	* updated elf_ia64_efi.lds and elf_ia32_efi.lds to include
	  new types data sections produced by recent version of gcc-3.x

2002-02-22  Stephane Eranian <eranian@hpl.hp.com>
	* release 3.0a
	* modified both IA-64 and IA-32 loader scripts to add support for the
	  new .rodata sections names (such as rodata.str2.8). Required
	  for new versions of gcc3.x.

2001-06-20  Stephane Eranian <eranian@hpl.hp.com>
	* release 3.0
	* split gnu-efi package in two different packages: the libary+include+crt and the bootloader.
	* removed W2U() hack and related files to get from wide-char to unicode. 
	* Use -fshort-wchar option for unicode.
	* restructured Makefiles now install under INSTALLROOT.

2001-04-06  Stephane Eranian <eranian@hpl.hp.com>

	* incorporated patches from David and Michael Johnston at Intel
	  to get the package to compile for IA-32 linux target.

	* Fixed ELILO to compile for Ia-32 (does not execute yet, though):
	  Makefile and start_kernel() function.

2001-04-06  Andreas Schwab <schwab@suse.de>

	* Fixed config.c  to
	  get the timeout directive to do something. implemented the global
	  root= directive.

	* Fix the efi_main() to deal with the -C option properly

2001-04-05  Stephane Eranian <eranian@hpl.hp.com>

	* update efi library to latest EFI toolkit 1.02 as distributed
	  by Intel. Fixed header + library files to compile with GCC

	* merged ELI and LILO (as of gnu-efi-1.1) together, mostly
	  taking the config file feature of ELI.

	* renamed LILO to ELILO to make the distinction

	* restructured code to make it easier to understand and maintain

	* fixed FPSWA driver checking and loading: we try all possible
	  files and let the driver itself figure out if it is the most
	  recent.
	* added support for compression (gzip) but keep support for plain
	  ELF image. ELILO autodetects the format

	* change the way the kernel is invoked. Now we call it in 
	  physical memory mode. This breaks the dependency between the
	  kernel code and the loader. No more lilo_start.c madness.

	* changed the way the boot_params are passed. We don't use the 
	  ZERO_PAGE_ADDR trick anymore. Instead we use EFI runtime memory.
	  The address of the structure is passed to the kernel in r28
	  by our convention.

	* released as gnu-efi-2.0

2001-04-03  David Mosberger  <davidm@hpl.hp.com>

	* gnuefi/reloc_ia32.c (_relocate): Change return type from "void"
	to "int".  Return error status if relocation fails for some
	reason.

	* gnuefi/elf_ia32_efi.lds: Drop unneeded ".rel.reloc" section.

	* gnuefi/crt0-efi-ia32.S (_start): Exit if _relocate() returns with
	non-zero exit status.

	* inc/ia32/efibind.h [__GNUC__]: Force 8-byte alignment for 64-bit
	types as that is what EFI appears to be expecting, despite the
	"#pragma pack()" at the beginning of the file!

2001-03-29  David Mosberger  <davidm@hpl.hp.com>

	* gnuefi/reloc_ia32.c: Add a couple of defines to work around
	libc/efilib collision on uint64_t et al.
	(_relocate): Use ELF32_R_TYPE() instead of ELFW(R_TYPE)().

	* gnuefi/crt0-efi-ia32.S (dummy): Add a dummy relocation entry.

2001-03-29  David Mosberger  <davidm@hpl.hp.com>

        * gnuefi/reloc_ia32.c: Add a couple of defines to work around
        libc/efilib collision on uint64_t et al.
        (_relocate): Use ELF32_R_TYPE() instead of ELFW(R_TYPE)().

        * gnuefi/crt0-efi-ia32.S (dummy): Add a dummy relocation entry.

2000-10-26  David Mosberger  <davidm@hpl.hp.com>
 
 	* gnuefi/elf_ia64_efi.lds: Mention .rela.sdata.
 
 	* Make.defaults (CFLAGS): Remove -nostdinc flags so we can pick
 	up the C compiler's stdarg.h.
 
 	* inc/stdarg.h: Remove this file.  It's not correct for gcc (nor
 	most other optimizing compilers).

2000-10-10  Stephane Eranian <eranian@hpl.hp.com>

	* cleaned up the error message and printing of those.
	* added support to load the FPSWA from a file in case support is not
	  present in the firmware already
	* fixed split_args() to do the right thing when you have leading spaces
	  before kernel name
	* changed the argify() function to rely on \0 instead of LoadOptionSize
	  as the field seems to be broken with current firmware
	* bumped version to 1.0

2000-10-04  David Mosberger  <davidm@hpl.hp.com>
 
	* gnuefi/reloc_ia64.S: Reserve space for up to 750 function descriptors.

	* gnuefi/elf_ia64_efi.lds: Add .sdata section for small data and
	put __gp in the "middle" of it.

	* gnuefi/crt0-efi-ia64.S (_start): Use movl/add to load
	gp-relative addresses that could be out of the range of the addl
	offset.
	* gnuefi/reloc_ia64.S (_relocate): Ditto.

	* apps/Makefile: Remove standard rules and include Make.rules instead.
	* lilo/Makefile: Ditto.

	* Make.rules: New file.

2000-08-04  Stephane Eranian <eranian@hpl.hp.com>
	* released version 0.9
	* incorporated ACPI changes for Asuza by NEC < kouchi@hpc.bs1.fc.nec.co.jp>
	* added support for initrd (-i option) original ELI code from Bill Nottingham <notting@redhat.com>)
	* lots of cleanups 
	* got rid of #ifdef LILO_DEBUG and uses macro instead
	* fix a few extra memory leaks in create_boot_params()
	* added exit capability just before starting the kernel

2000-06-22  David Mosberger  <davidm@hpl.hp.com>

	* gnuefi/elf_ia64_efi.lds: Add .srodata, .ctors, .IA64.unwind,
	.IA64.unwind_info to .data section and .rela.ctors to .rela
	section.

2000-04-03  David Mosberger  <davidm@hpl.hp.com>

	* lilo/lilo.c (LILO_VERSION): Up version number to 0.9.

	* gnuefi/elf_ia64_efi.lds: Include .IA_64.unwind and
	.IA_64.unwind_info in .data segment to avoid EFI load error
	"ImageAddress: pointer outside of image" error due to the .dynsym
	relocations against these sections.

	* ChangeLog: Moved from lilo/ChangeLogs.

	* gnuefi/reloc_ia64.S: fixed typo: .space directive had constant
	100 hardcoded instead of using MAX_FUNCTION_DESCRIPTORS
	macro. Duh.

Fri Mar 17 15:19:18 PST 2000 Stephane Eranian <eranian@hpl.hp.com>

	* Released 0.8
	* replace the  getopt.c with new version free with better license
	* created a documentation file
	* fix a couple of memory leaks
	* code cleanups
	* created a separate directory for lilo in the gnu-efi package.
	* added support for the BOOT_IMAGE argument to kernel
	* default is to build natively now
