Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

# Makefile for making ELF bootable images for booting on CHRP
# using Open Firmware.
#
# Geert Uytterhoeven September 1997
#
# Based on coffboot by Paul Mackerras
# Simplified for ppc64 by Todd Inglett
#
# NOTE: this code is built for 32 bit in ELF32 format even though
# it packages a 64 bit kernel. We do this to simplify the
# bootloader and increase compatibility with OpenFirmware.
#
# To this end we need to define BOOTCC, etc, as the tools
# needed to build the 32 bit image. These are normally HOSTCC,
# but may be a third compiler if, for example, you are cross
# compiling from an intel box. Once the 64bit ppc gcc is
# stable it will probably simply be a compiler switch to
# compile for 32bit mode.
# To make it easier to setup a cross compiler,
# CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
# in the toplevel makefile.
[POWERPC] Create a "wrapper" script and use it in arch/powerpc/boot This puts the knowledge of how to create various sorts of zImage wrappers into a script called "wrapper" that could be used outside of the kernel tree. This changes arch/powerpc/boot so it first builds the files that the wrapper script needs, then runs it to create whatever flavours of zImage are required. This version does uImages as well. The zImage names are changed slightly; zImage.pseries is the one with the PT_NOTE program header entry added, and zImage.pmac is the one without. If the zImage.pseries gets made, it will also get hardlinked to zImage; otherwise, if zImage.pmac is made, it gets hardlinked to zImage. Signed-off-by: Paul Mackerras <paulus@samba.org>

[PATCH] zlib_inflate: Upgrade library code to a recent version Upgrade the zlib_inflate implementation in the kernel from a patched version 1.1.3/4 to a patched 1.2.3. The code in the kernel is about seven years old and I noticed that the external zlib library's inflate performance was significantly faster (~50%) than the code in the kernel on ARM (and faster again on x86_32). For comparison the newer deflate code is 20% slower on ARM and 50% slower on x86_32 but gives an approx 1% compression ratio improvement. I don't consider this to be an improvement for kernel use so have no plans to change the zlib_deflate code. Various changes have been made to the zlib code in the kernel, the most significant being the extra functions/flush option used by ppp_deflate. This update reimplements the features PPP needs to ensure it continues to work. This code has been tested on ARM under both JFFS2 (with zlib compression enabled) and ppp_deflate and on x86_32. JFFS2 sees an approx. 10% real world file read speed improvement. This patch also removes ZLIB_VERSION as it no longer has a correct value. We don't need version checks anyway as the kernel's module handling will take care of that for us. This removal is also more in keeping with the zlib author's wishes (http://www.zlib.net/zlib_faq.html#faq24) and I've added something to the zlib.h header to note its a modified version.

[POWERPC] zImage: Cleanup and improve zImage entry point This patch re-organises the way the zImage wrapper code is entered, to allow more flexibility on platforms with unusual entry conditions. After this patch, a platform .o file has two options: 1) It can define a _zimage_start, in which case the platform code gets control from the very beginning of execution. In this case the platform code is responsible for relocating the zImage if necessary, clearing the BSS, performing any platform specific initialization, and finally calling start() to load and enter the kernel. 2) It can define platform_init(). In this case the generic crt0.S handles initial entry, and calls platform_init() before calling start(). The signature of platform_init() is changed, however, to take up to 5 parameters (in r3..r7) as they come from the platform's initial loader, instead of a fixed set of parameters based on OF's usage. When using the generic crt0.S, the platform .o can optionally supply a custom stack to use, using the BSS_STACK() macro. If this is not supplied, the crt0.S will assume that the loader has supplied a usable stack. In either case, the platform code communicates information to the generic code (specifically, a PROM pointer for OF systems, and/or an initrd image address supplied by the bootloader) via a global structure "loader_info". In addition the wrapper script is rearranged to ensure that the platform .o is always linked first. This means that platforms where the zImage entry point is at a fixed address or offset, rather than being encoded in the binary header can be supported using option (1).

[POWERPC] zImage: Add more flexible gunzip convenience functions At present, arch/powerpc/boot/main.c includes a gunzip() function which is a convenient wrapper around zlib. However, it doesn't conveniently allow decompressing part of an image to one location, then the remainder to a different address. This patch adds a new set of more flexible convenience wrappers around zlib, moving them to their own file, gunzip_util.c, in the process. These wrappers allow decompressing sections of the compressed image to different locations. In addition, they transparently handle uncompressed data, avoiding special case code to handle uncompressed vmlinux images. The patch also converts main.c to use the new wrappers, using the new flexibility to avoid decompressing the vmlinux's ELF header twice as we did previously. That in turn means we avoid extending our allocations for the vmlinux to allow space for the extra copy of the ELF header.

[POWERPC] zImage: Cleanup and improve zImage entry point This patch re-organises the way the zImage wrapper code is entered, to allow more flexibility on platforms with unusual entry conditions. After this patch, a platform .o file has two options: 1) It can define a _zimage_start, in which case the platform code gets control from the very beginning of execution. In this case the platform code is responsible for relocating the zImage if necessary, clearing the BSS, performing any platform specific initialization, and finally calling start() to load and enter the kernel. 2) It can define platform_init(). In this case the generic crt0.S handles initial entry, and calls platform_init() before calling start(). The signature of platform_init() is changed, however, to take up to 5 parameters (in r3..r7) as they come from the platform's initial loader, instead of a fixed set of parameters based on OF's usage. When using the generic crt0.S, the platform .o can optionally supply a custom stack to use, using the BSS_STACK() macro. If this is not supplied, the crt0.S will assume that the loader has supplied a usable stack. In either case, the platform code communicates information to the generic code (specifically, a PROM pointer for OF systems, and/or an initrd image address supplied by the bootloader) via a global structure "loader_info". In addition the wrapper script is rearranged to ensure that the platform .o is always linked first. This means that platforms where the zImage entry point is at a fixed address or offset, rather than being encoded in the binary header can be supported using option (1).

[POWERPC] Create a "wrapper" script and use it in arch/powerpc/boot This puts the knowledge of how to create various sorts of zImage wrappers into a script called "wrapper" that could be used outside of the kernel tree. This changes arch/powerpc/boot so it first builds the files that the wrapper script needs, then runs it to create whatever flavours of zImage are required. This version does uImages as well. The zImage names are changed slightly; zImage.pseries is the one with the PT_NOTE program header entry added, and zImage.pmac is the one without. If the zImage.pseries gets made, it will also get hardlinked to zImage; otherwise, if zImage.pmac is made, it gets hardlinked to zImage. Signed-off-by: Paul Mackerras <paulus@samba.org>

[POWERPC] Create a "wrapper" script and use it in arch/powerpc/boot This puts the knowledge of how to create various sorts of zImage wrappers into a script called "wrapper" that could be used outside of the kernel tree. This changes arch/powerpc/boot so it first builds the files that the wrapper script needs, then runs it to create whatever flavours of zImage are required. This version does uImages as well. The zImage names are changed slightly; zImage.pseries is the one with the PT_NOTE program header entry added, and zImage.pmac is the one without. If the zImage.pseries gets made, it will also get hardlinked to zImage; otherwise, if zImage.pmac is made, it gets hardlinked to zImage. Signed-off-by: Paul Mackerras <paulus@samba.org>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[POWERPC] Fix build of cell zImage.initrd The patch adding support for zImage.ps3 didn't add a zImage.initrd.ps3 target causing builds of zImage.initrd to fail when ps3 is included in the .config. The current method of generating ps3 images doesn't support initrd's yet, so we create a dummy target that only displays a warning message instead.
