[PATCH] zlib_inflate: Upgrade library code to a recent version

2006-06-22T22:05:58Z

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/32: Generate miboot images with ARCH=powerpc

2006-01-15T02:00:08Z

Miboot images are apparently still used on some old 32-bit powermacs, so build them with ARCH=powerpc if we're 32-bit and powermac support is enabled. Signed-off-by: Paul Mackerras

powerpc: Make COFF zImages for old 32-bit powermacs

2006-01-14T04:04:06Z

This adds code to build zImage.coff and/or zImage.initrd.coff when CONFIG_PPC32 and CONFIG_PPC_PMAC are defined. It also restructures the OF client code and adds some workarounds for OF quirks on the older machines. Signed-off-by: Paul Mackerras

[PATCH] powerpc: Fix clean_files in arch/powerpc/boot Makefile

2006-01-11T05:28:13Z

clean-files was being set twice rather than being appended to. Signed-off-by: Kumar Gala Signed-off-by: Paul Mackerras

[PATCH] powerpc: Fix suboptimal uImage target

2006-01-09T03:50:25Z

Sam Ravnborg pointed out that calling if_changed was redundant in the rule since a prerequisite had to have changed for us to get there. Signed-off-by: Kumar Gala Signed-off-by: Paul Mackerras

[PATCH] powerpc: Add support for building uImages

2006-01-09T03:50:21Z

powerpc: Add support for building uImages Add support to build a kernel image bootable by u-boot. Most of the makefile foo is taken from arch/ppc/boot/images/Makefile Signed-off-by: Kumar Gala Signed-off-by: Paul Mackerras

powerpc: Move ppc64 boot wrapper code over to arch/powerpc

2005-11-16T02:52:21Z

This also extends the code to handle 32-bit ELF vmlinux files as well as 64-bit ones. This is sufficient for booting on new-world 32-bit powermacs (i.e. all recent machines). Signed-off-by: Paul Mackerras
