lib/decompressors: use real out buf size for gunzip with kernel

2015-09-10T20:29:01+00:00

When loading x86 64bit kernel above 4GiB with patched grub2, got kernel gunzip error. | early console in decompress_kernel | decompress_kernel: | input: [0x807f2143b4-0x807ff61aee] | output: [0x807cc00000-0x807f3ea29b] 0x027ea29c: output_len | boot via startup_64 | KASLR using RDTSC... | new output: [0x46fe000000-0x470138cfff] 0x0338d000: output_run_size | decompress: [0x46fe000000-0x47007ea29b] <=== [0x807f2143b4-0x807ff61aee] | | Decompressing Linux... gz... | | uncompression error | | -- System halted the new buffer is at 0x46fe000000ULL, decompressor_gzip is using 0xffffffb901ffffff as out_len. gunzip in lib/zlib_inflate/inflate.c cap that len to 0x01ffffff and decompress fails later. We could hit this problem with crashkernel booting that uses kexec loading kernel above 4GiB. We have decompress_* support: 1. inbuf[]/outbuf[] for kernel preboot. 2. inbuf[]/flush() for initramfs 3. fill()/flush() for initrd. This bug only affect kernel preboot path that use outbuf[]. Add __decompress and take real out_buf_len for gunzip instead of guessing wrong buf size.

Kbuild: centralize MKIMAGE and cmd_uimage definitions

2012-03-26T13:49:20+00:00

All ARCHs have the same definition of MKIMAGE. Move it to Makefile.lib to avoid duplication. All ARCHs have similar definitions of cmd_uimage. Place a sufficiently parameterized version in Makefile.lib to avoid duplication.

sh: kexec: Add PHYSICAL_START

2011-10-28T06:03:43+00:00

Add PHYSICAL_START kernel configuration parameter to set the address at which the kernel should be loaded. It has been observed on an sh7757lcr that simply modifying MEMORY_START does not achieve this goal for 32bit sh. This is due to MEMORY_OFFSET in arch/sh/kernel/vmlinux.lds.S bot being based on MEMORY_START on such systems. Signed-off-by: Simon Horman Signed-off-by: Paul Mundt

sh: Remove compressed kernel libgcc dependency.

2011-06-06T08:57:58+00:00

SH-2A is unable to combine the kernel and libgcc objects due to fundamental disagreements over FDPIC settings. As the kernel already contains all of the libgcc bits broken out, there's not much need to bother with the linking anymore, as everything can already be derived from the lib dir. This simply plugs in the necessary bits to ensure that everything is built uniformly, enabling us to wean the compressed build off of explicit libgcc linking.

mmc: Add MMC_PROGRESS_*

2011-03-24T16:24:57+00:00

This is my second attempt to make this enum generally available. The first attempt added MMCIF_PROGRESS_* to include/linux/mmc/sh_mmcif.h. However this is not sufficiently generic as the enum will be used by SDHI boot code. Signed-off-by: Simon Horman Signed-off-by: Paul Mundt

sh: Enable CONFIG_GCOV_PROFILE_ALL for sh

2011-02-15T07:47:17+00:00

This patch enables gcov kernel profiling over the whole kernel for sh. Profiling of specific files individually already worked. A handful of files have to be explicitly excluded from the profiling to avoid breaking things, notably pmb.c. Signed-off-by: Chris Smith Signed-off-by: Stuart Menefy Signed-off-by: Paul Mundt

mmc, sh: Remove sh_mmcif_boot_slurp()

2010-12-08T07:24:28+00:00

As the only caller of sh_mmcif_boot_do_read() is sh_mmcif_boot_slurp() the configuration portion of sh_mmcif_boot_slurp() can be merged into sh_mmcif_boot_do_read(). Once this is done sh_mmcif_boot_slurp() is only a call to sh_mmcif_boot_do_read() with platform specific information - the offset that images are stored on MMC. So make the sh_mmcif_boot_do_read() call directly from platform code and remove sh_mmcif_boot_slurp() altogether. Cc: Magnus Damm Signed-off-by: Simon Horman Signed-off-by: Paul Mundt
