2009-05-01libdrm/intel: assert that clients are using bo refcounting correctlyKeith Packard
Add assertions to drm_intel_gem_bo_reference, drm_intel_gem_bo_reference_locked and drm_intel_gem_bo_unreference_locked that the object has not been freed (refcount > 0). Mistakes in refcounting lead to attempts to insert a bo into a free list more than once which causes application failure as empty free lists are dereferenced as buffer objects.

Fixes assertion failures on later use of the object.

2009-04-10Revert "libdrm: speed up connector & mode fetching"Jesse Barnes
This reverts commit cd5c66c659168cbe2e3229ebf8be79f764ed0ee1. It broke too many kernel assumptions about the double ioctl (connector status, mode fetching, etc.)
2009-03-30libdrm: speed up connector & mode fetchingJesse Barnes
This patch speeds up drmModeGetConnector by pre-allocating mode & property info space before calling into the kernel.  In many cases this pre-allocation will be sufficient to hold the returned values (it's easy enough to tweak if the common case becomes larger), which means we don't have to make the second call, which saves a lot of time.

2009-03-26libdrm/intel: support GTT maps correctlyJesse Barnes
libdrm has some support for GTT mapping already, but there are bugs with it (no surprise since it hasn't been used much). In fixing 20803, I found that sharing bo_gem->virtual was a bad idea, since a previously mapped object might not end up getting GTT mapped, leading to corruption. So this patch splits the fields according to use, taking care to unmap both at free time (but preserving the map caching). There's still a risk we might run out of mappings (there's a sysctl tunable for max number of mappings per process, defaulted to 64k or so it looks like) but at least GTT maps will work with these changes (and some others for fixing PAT breakage in the kernel).

2009-03-18libdrm/nouveau: implement bo_handle_get for !mm_enabledBen Skeggs
bo_handle_ref on !mm_enabled treats handle as an offset, make bo_handle_get do the same rather than failing.
2009-03-16libdrm_nouveau: The handle that is passed to mmap needs to be drm_handle_tRobert Noland
drm_handle_t is defined to be a u32 on linux and a u64 on everything else. This addresses an issue on FreeBSD amd64 where the map offsets may be greater than 32bits. When the handle is cast to 32bit, mmap cannot match the requested map and causes X to crash. This should be a NOOP on linux since drm_handle_t is always 32bit.

2009-02-27intel: Update reloc_tree_size of the first buffer when we count the tree size.Eric Anholt
This helps avoid the n^2 performance cost of counting tree size when we get a lot of relocations into our batch buffer. rgb10text on keithp's laptop went from 136k glyphs/sec to 234k glyphs/sec.

This avoids using the oldest BO in the BO cache and waiting for it to be idle before we turn around and render to it with the GPU. Thanks to Chris Wilson for pointing out how silly we were being.

2009-01-07libdrm: only check for vblank timeout if we caught EINTRJesse Barnes
Michel caught a case where we might overwrite a success or other return value with EBUSY, so check the return value before checking for the timeout condition.
2009-01-07libdrm: add timeout handling to drmWaitVBlankJesse Barnes
In some cases, vblank interrupts may be disabled or otherwise broken. The kernel has a 3s timeout builtin to handle these cases, but the X server's SIGALM for cursor handling may interrupt vblank wait ioctls, causing libdrm to restart the ioctl, making the kernel's timeout useless. This change tracks time across ioctl restarts and returns EBUSY to the caller if the expected vblank sequence doesn't occur within 1s of the first call. Fixes fdo bz #18041, which is caused by a drmWaitVBlank hanging due to the corresponding pipe getting disabled (thus preventing further events from coming in).
2008-12-17intel: Cache tiling/swizzle state in user mode. Reset tiling on reuse.Keith Packard

2008-12-17intel: return error status from drm_intel_gem_bo_mapKeith Packard

2008-12-17intel: Dump out memory usage information when the kernel fails to pinKeith Packard
The execbuffer ioctl returns ENOMEM when it fails to pin all of the buffers in the GTT. This is usually caused by the DRM client attempting to use too much memory in a single request. Dumping out the requested and available memory values should help point out failures in the DRM code to catch over commitments of this form. Signed-off-by: Keith Packard <keithp@keithp.com>
