46 *maintainer note, this probably introduces a bug, in light of this
47 note from the patch submitter --> "On some x86_64 systems with
48 EFI1.10 firmware I tested, early boot messages did not appear on console.
49 However, I didn't encounter this behavior on x86_64 systems with UEFI2.0

69 * x86_64/sysdeps.c -- new file, system stuff for x86_64
70 * elilo.txt -- documentation update, add Intel to copyright
71 * README.gnu-efi -- documentation update for x86_64
72 2006-01-27 Alex Williamson <alex.williamson@hp.com>
73 * Found a couple more places where vmcode isn't zeroed, causing the
74 option to get carried over to labels it shouldn't.
75 2006-01-09 Brett Johnson <brett@hp.com>
77 2005-12-22 Alex Williamson <alex.williamson@hp.com>
78 * Fixed vmcode_name initialization in textmenu chooser
79 2005-12-01 Alex Williamson <alex.williamson@hp.com>
80 * Applied patch from Fred Yang <fred.yang@intel.com> to support the
81 vmm= boot option. This option specifies the kernel image for a
82 virtual machine monitor (aka hypervisor). The vmm= and image=
83 options are used together to load both the hypervisor kernel and
84 the guest domain kernel into memory. If a vmm= option is not
85 specified, elilo defaults to the old behavior of loading and booting
87 * Added support for compressed image= files when used with the vmm=
88 option. If the image= file is detected to be gzip compressed, the
89 image will be uncompressed into memory before it is provided to the
90 hypervisor. Any combination of compressed and uncompressed images
91 can be used for the image and vmm options.
92 2005-09-15 Brett Johnson <brett@hp.com>
93 * Applied patch from Tristan Gingold to add dcache flush and sync with
94 icache to gzip and plain loaders. This ommision was just noticed now
95 due to the much larger caches in Montecito, and the smaller size of
96 Xen (as compared to the linux kernel).
97 2004-09-27 Brett Johnson <brett@hp.com>
98 * Increase the hardcoded size of the texmenu chooser menu from 16 to 64
99 2004-09-23 Brett Johnson <brett@hp.com>
100 * Fix for 924147. Thanks to Stephanie Schaaf <sas@sgi.com> for a patch
101 that the fix is based on.
102 2004-02-19 Brett Johnson <brett@hp.com>
103 * Fixed bug where default image initrd would carry over to another
104 image that was selected interactively (iff the newly selected image
105 did not have an initrd).
106 * Added support for subnet-specific config files in netfs.
107 2004-02-17 Brett Johnson <brett@hp.com>
108 * integrated ia32 compressed kernel support from Matt Tolentino
109 <matthew.e.tolentino@intel.com>

114 Tolentino <matthew.e.tolentino@intel.com>
115 2003-08-13 Stephane Eranian <eranian@hpl.hp.com>
116 * updated elilo.txt and netbooting.txt
117 * fix a bug in choosers/simple.c:print_infos().
118 it needs to check if config file path is absolute
119 when printing filename.
120 * move definitions of CHAR_SLASH CHAR_BACKSLASH to elilo.h
121 * fix a bug in read_config() where it would try other
122 filename even when the user explicitely specified one
123 via -C, now it fails it that file cannot be opened.
124 * updated simple chooser set of builtin command keys
125 * command keys are only valid if first on the line
126 * increase default buffer size and increment when netbooting
127 2003-06-04 Stephane Eranian <eranian@hpl.hp.com>
128 * fix fs/netfs.c to work with recent version
129 of EFI (14.61 or higher) which do not have the
130 TFTP problem anymore. fix submitted by Guy Laborde
131 2003-04-21 Stephane Eranian <eranian@hpl.hp.com>
132 * ext2fs support is turned off by default to avoid
133 problems with ext3-formatted partitions.
134 * added gcc version check. MUST use 3.0 or higher
135 2003-03-03 Stephane Eranian <eranian@hpl.hp.com>
136 * added check on dev_tab in fs/*fs.c:*_uninstall()
137 2003-02-07 Stephane Eranian <eranian@hpl.hp.com>
138 * clean up in glue_localfs.c w.r.t. CHAR16 in set_default_path()
139 * added support for extracting basename of bootloader path
140 when using BOOTP (DHCP) only. The prefix is then used for all files
141 open via netfs. Suggestion and initial patch by Guy Laborde from HP.
142 2003-01-28 Stephane Eranian <eranian@hpl.hp.com>
143 * fix the set_default_path() routine in glue_localfs.c. It would not
144 correctly get the basename of the devpath. This caused the
145 elilo.conf not to be found sometimes.
146 2003-01-21 Stephane Eranian <eranian@hpl.hp.com>
147 * fix bug in glue_netfs.c convert_ip2decstr() which caused some IP
148 addresses to be incorrectly converted to strings.
149 2002-11-01 Stephane Eranian <eranian@hpl.hp.com>
150 * fix bug in -r option for IA64. There is no argument to this option.
151 2002-10-15 Stephane Eranian <eranian@hpl.hp.com>
152 * fixed a double free bug for the kernel memory in case of abort.
153 (bug spotted by Levent Akyl from Intel)
155 2002-09-14 Stephane Eranian <eranian@hpl.hp.com>
156 * applied patch from Andreas Schwab <schwab@suse.de> to eliloalt.c.

158 2002-09-12 Stephane Eranian <eranian@hpl.hp.com>
159 * removed extra free() from fs/ext2fs.c:ext2fs_init_state().
160 Bug report and fix by NOMURA Jun'ichi <j-nomura@ce.jp.nec.com>
161 * rewrote fs/ext2fs.c:read_bytes() to large memory stack buffer which
162 was bigger than the 128KB limit of EFI causing some weird fimrware
163 errors. bug reported by OMURA Jun'ichi <j-nomura@ce.jp.nec.com>

167 when aborting at the elilo prompt when netbooted.
168 2002-08-26 Stephane Eranian <eranian@hpl.hp.com>
169 * fixed devschemes/simple.c to use SPrint() instead of its own buggy
170 conversion code (spotted by Richard Hirst).

188 initialization bug in choosers/textmenu.c
189 * applied patch from Richard Hirst <rhirst@linuxcare.com> to make elilo
190 compliant with EFI spec with regards to where it looks for files.
191 With this patch, elilo will look in the directory it was loaded
192 from, not on the root of the partition anymore.

244 and ignore the prompt directive.
246 2001-08-15 Brent Casavant <bcasavan@sgi.com>
247 * fix a bug in config.c:find_option() where it would do
248 a strXcmp() on a NULL string.
250 2001-08-01 Stephane Eranian <eranian@hpl.hp.com>
251 * fixed bug in fs/netfs.c where it would not handle the small buffer
252 error correctly. The retry path was not allocating a bigger buffer.
253 * Global config options are now used if the user specifies a non-label
254 load target, i.e. a kernel image file.

268 * fixed to wait_timeout() to correct the problem with the interactive prompt when
269 return is hit directly when no text
270 * fixed command line argument destruction problem, now we make a copy of them. This
271 was affecting elilo when called directly from bootmanager with NVRAM options.
273 2001-06-28 Stephane Eranian <eranian@hpl.hp.com>
274 * removed W2U() hack to get from wide-char to unicode. Use -fshort-wchar option instead.
275 * split gnu-efi package in two different packages: the libary+include+crt and the bootloader.
276 * restructured the fileops module. Now use direct function calls.
277 * added support for accessing files on different devices.

279 * created a strops.c file to incorporate all string operations functions.
280 * added support for ext2fs filesystem.
281 * restructured code to allow additional filesystems to be added easily.
282 * cleaned up add-on chooser interface.
283 * restructured code to use the EFI protocol interface to install filesystems.
284 * added compile-time options to turn on and off specific filesystems.
285 * added support for architecture specific configuration options (elilo.conf).
286 * added fpswa option to IA-64 to designate a fpswa driver file.
287 * incoporated IA-32 support from Mike Johnston <michael.johnston@intel.com>
288 * incorporated rewritten gzip.c:flush_window() from Tony Luck <tony.luck@intel.com>
289 * added interface for custom device naming schemes (devnames directory).
290 * added support for 2 possible config file (now just on netboot). The first
291 (primary) choice uses a host specific filename based on the IP address. Suggestion
292 from Egan Ford <egan@sense.net>.
294 2001-04-06 Stephane Eranian <eranian@hpl.hp.com>
296 * incorporated patches from David and Michael Johnston at Intel
297 to get the package to compile for IA-32 linux target.
299 * Fixed ELILO to compile for Ia-32 (does not execute yet, though):
300 Makefile and start_kernel() function.
302 2001-04-06 Andreas Schwab <schwab@suse.de>
305 get the timeout directive to do something. implemented the global
308 * Fix the efi_main() to deal with the -C option properly
310 2001-04-05 Stephane Eranian <eranian@hpl.hp.com>
312 * update efi library to latest EFI toolkit 1.02 as distributed
313 by Intel. Fixed header + library files to compile with GCC
315 * merged ELI and LILO (as of gnu-efi-1.1) together, mostly
316 taking the config file feature of ELI.
318 * renamed LILO to ELILO to make the distinction
320 * restructured code to make it easier to understand and maintain
322 * fixed FPSWA driver checking and loading: we try all possible
323 files and let the driver itself figure out if it is the most
325 * added support for compression (gzip) but keep support for plain
326 ELF image. ELILO autodetects the format
328 * change the way the kernel is invoked. Now we call it in
329 physical memory mode. This breaks the dependency between the
330 kernel code and the loader. No more lilo_start.c madness.
332 * changed the way the boot_params are passed. We don't use the
333 ZERO_PAGE_ADDR trick anymore. Instead we use EFI runtime memory.
334 The address of the structure is passed to the kernel in r28
337 * released as gnu-efi-2.0
339 2001-04-03 David Mosberger <davidm@hpl.hp.com>
341 * gnuefi/reloc_ia32.c (_relocate): Change return type from "void"

348 non-zero exit status.
350 * inc/ia32/efibind.h [__GNUC__]: Force 8-byte alignment for 64-bit
351 types as that is what EFI appears to be expecting, despite the
352 "#pragma pack()" at the beginning of the file!
354 2001-03-29 David Mosberger <davidm@hpl.hp.com>
356 * gnuefi/reloc_ia32.c: Add a couple of defines to work around
357 libc/efilib collision on uint64_t et al.
358 (_relocate): Use ELF32_R_TYPE() instead of ELFW(R_TYPE)().
360 * gnuefi/crt0-efi-ia32.S (dummy): Add a dummy relocation entry.
362 2001-03-29 David Mosberger <davidm@hpl.hp.com>
364 * gnuefi/reloc_ia32.c: Add a couple of defines to work around
365 libc/efilib collision on uint64_t et al.
366 (_relocate): Use ELF32_R_TYPE() instead of ELFW(R_TYPE)().
368 * gnuefi/crt0-efi-ia32.S (dummy): Add a dummy relocation entry.
370 2000-10-26 David Mosberger <davidm@hpl.hp.com>
372 * gnuefi/elf_ia64_efi.lds: Mention .rela.sdata.
374 * Make.defaults (CFLAGS): Remove -nostdinc flags so we can pick
375 up the C compiler's stdarg.h.
377 * inc/stdarg.h: Remove this file. It's not correct for gcc (nor
378 most other optimizing compilers).
380 2000-10-10 Stephane Eranian <eranian@hpl.hp.com>
382 * cleaned up the error message and printing of those.
383 * added support to load the FPSWA from a file in case support is not
384 present in the firmware already
385 * fixed split_args() to do the right thing when you have leading spaces
387 * changed the argify() function to rely on \0 instead of LoadOptionSize
388 as the field seems to be broken with current firmware
389 * bumped version to 1.0
391 2000-10-04 David Mosberger <davidm@hpl.hp.com>
393 * gnuefi/reloc_ia64.S: Reserve space for up to 750 function descriptors.
395 * gnuefi/elf_ia64_efi.lds: Add .sdata section for small data and
396 put __gp in the "middle" of it.
398 * gnuefi/crt0-efi-ia64.S (_start): Use movl/add to load
399 gp-relative addresses that could be out of the range of the addl
401 * gnuefi/reloc_ia64.S (_relocate): Ditto.
403 * apps/Makefile: Remove standard rules and include Make.rules instead.
404 * lilo/Makefile: Ditto.
406 * Make.rules: New file.

413 * got rid of #ifdef LILO_DEBUG and uses macro instead
414 * fix a few extra memory leaks in create_boot_params()
415 * added exit capability just before starting the kernel
417 2000-06-22 David Mosberger <davidm@hpl.hp.com>
