2011-01-13drm/i915/execbuffer: Clear domains before beginning reloc processingChris Wilson
After reordering the sequence of relocating objects, commit 6fe4f1404, we can no longer rely on seeing all reloc targets prior to performing the relocation. As a result we were ignoring the need to flush objects from the render cache and invalidate the sampler caches, resulting in rendering glitches. So we need to clear the relocation domains earlier.

2011-01-13drm/i915/execbuffer: Reorder relocations to match new object orderChris Wilson
On the fault path, commit 6fe4f140 introduction a regression whereby it changed the sequence of the objects but continued to use the original ordering of relocation entries. The result was that incorrect GTT offsets were being fed into the execbuffer causing lots of misrendering and potential hangs.

2011-01-13drm/i915: Fix error handler to capture the first batch after the seqnoChris Wilson
Whilst we had no older batches on the active list, everything was fine. However, if the GPU is free running and the requests are only being reaped by the periodic retirer, than the current seqno may not be at the start of the list. In this case we need to select the first batch after the last seqno written by the gpu and not inclusive of the seqno. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2011-01-13netfilter: ctnetlink: fix loop in ctnetlink_get_conntrack()Pablo Neira Ayuso
This patch fixes a loop in ctnetlink_get_conntrack() that can be triggered if you use the same socket to receive events and to perform a GET operation. Under heavy load, netlink_unicast() may return -EAGAIN, this error code is reserved in nfnetlink for the module load-on-demand. Instead, we return -ENOBUFS which is the appropriate error code that has to be propagated to user-space.

2011-01-13x86: support XZ-compressed kernelLasse Collin
This integrates the XZ decompression code to the x86 pre-boot code. mkpiggy.c is updated to reserve about 32 KiB more buffer safety margin for kernel decompression. It is done unconditionally for all decompressors to keep the code simpler. The XZ decompressor needs around 30 KiB of heap, so the heap size is increased to 32 KiB on both x86-32 and x86-64. Documentation/x86/boot.txt is updated to list the XZ magic number. With the x86 BCJ filter in XZ, XZ-compressed x86 kernel tends to be a few percent smaller than the equivalent LZMA-compressed kernel. Signed-off-by: Lasse Collin <lasse.collin@tukaani.org> Cc: "H.

2011-01-13decompressors: add boot-time XZ supportLasse Collin
This implements the API defined in <linux/decompress/generic.h> which is used for kernel, initramfs, and initrd decompression. This patch together with the first patch is enough for XZ-compressed initramfs and initrd; XZ-compressed kernel will need arch-specific changes. The buffering requirements described in decompress_unxz.c are stricter than with gzip, so the relevant changes should be done to the arch-specific code when adding support for XZ-compressed kernel. Similarly, the heap size in arch-specific pre-boot code may need to be increased (30 KiB is enough). The XZ decompressor needs memmove(), memeq() (memcmp() == 0), and memzero() (memset(ptr, 0, size)), which aren't available in all arch-specific pre-boot environments. I'm including simple versions in decompress_unxz.c, but a cleaner solution would naturally be nicer. Signed-off-by: Lasse Collin <lasse.collin@tukaani.org> Cc: "H.

2011-01-13decompressors: add XZ decompressor moduleLasse Collin
In userspace, the .lzma format has become mostly a legacy file format that got superseded by the .xz format. Similarly, LZMA Utils was superseded by XZ Utils. These patches add support for XZ decompression into the kernel. Most of the code is as is from XZ Embedded <http://tukaani.org/xz/embedded.html>. It was written for the Linux kernel but is usable in other projects too. Advantages of XZ over the current LZMA code in the kernel: - Nice API that can be used by other kernel modules; it's not limited to kernel, initramfs, and initrd decompression. - Integrity check support (CRC32) - BCJ filters improve compression of executable code on certain architectures. These together with LZMA2 can produce a few percent smaller kernel or Squashfs images than plain LZMA without making the decompression slower. This patch: Add the main decompression code (xz_dec), testing module (xz_dec_test), wrapper script (xz_wrap.sh) for the xz command line tool, and documentation. The xz_dec module is enough to have a usable XZ decompressor e.g. for Squashfs. Signed-off-by: Lasse Collin <lasse.collin@tukaani.org> Cc: "H.

2011-01-13Decompressors: fix callback-to-callback mode in decompress_unlzo.cLasse Collin
Callback-to-callback decompression mode is used for initrd (not initramfs). The LZO wrapper is broken for this use case for two reasons: - The argument validation is needlessly too strict by requiring that "posp" is non-NULL when "fill" is non-NULL. - The buffer handling code didn't work at all for this use case. I tested with LZO-compressed kernel, initramfs, initrd, and corrupt (truncated) initramfs and initrd images. Signed-off-by: Lasse Collin <lasse.collin@tukaani.org> Cc: "H.
