2011-12-29intel: Fix a ton of signed vs unsigned and const char *warningsEric Anholt
We've got a different (better) set of warning flags in place in this tree. Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Eugeni Dodonov <eugeni@dodonov.net>
2011-12-29intel: Fix Wsigned-compare warnings (soon to be enabled).Eric Anholt

2011-12-29intel: Get intel_decode.c minimally building.Eric Anholt
My plan is to use this drm_intel_dump_batchbuffer() interface for the current GPU tools, and the current Mesa batch dumping usage, while eventually building more interesting interfaces for other uses. Warnings are currently suppressed by using a helper lib with CFLAGS set manually, because the code is totally not ready for libdrm's warnings setup.

2011-12-29intel: Minor style tweaks after Lindent.Eric Anholt
Some comments weren't wrapped, and for some reason uint32_t *data got an extra space (while other instances of "type *identifier" didn't), and the indentation of the opcode-list structs got trashed. Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Eugeni Dodonov <eugeni@dodonov.net>
2011-12-29intel: Reformat intel_decode.c from intel-gpu-tools using Lindent.Eric Anholt
We generally go for kernel style in this tree, and this 4-space indent stuff was bothering me. The new results have some ugly bits, but they're in places where we desperately want to be using helper functions anyway.

2011-12-29intel: intel: Add IS_GEN[567] macros.Eric Anholt
These will be used by intel_decode.c, and were taken from intel-gpu-tools. Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Eugeni Dodonov <eugeni@dodonov.net>
2011-12-29intel: Make intel_chipset handle devid directly.Eric Anholt
This will make these macros reusable from intel_decode.c, which doesn't have a bufmgr_gem context, without faking the struct. We should generally only be using these macros from bufmgr_gem context setup anyway. Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Eugeni Dodonov <eugeni@dodonov.net>
2011-12-29intel: Import intel_decode.c from intel-gpu-tools.Eric Anholt
This is from commit dd9a5b4f7fb07c78db4e7481bedca1b981030e3f. We've been sharing this file between that repo and Mesa, and it's time to build a real interface using it. I'm also hoping to apply some of its packet-walking logic for AUB dumping and batch validation purposes. Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Eugeni Dodonov <eugeni@dodonov.net>
2011-12-14intel: Reset vma list upon purgeChris Wilson
During free we unconditionally delete the bo from the vma cache. This relies on the its list member being kept in a sane state. This fails after the object is purged, as the purge operation performs a pure deletion and doesn't reset the list member, leaving a pair of dangling pointers.

2011-12-13intel: Remove the fresh assertions used to debug the vma cacheingChris Wilson

2011-12-06intel: Evict cached VMA in order to make room for new mappingsChris Wilson
As the max number of VMA mappings is a hard per-process limit, we need to include the number of currently active mappings when evicting in order to make room for a new mmap. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-12-05intel: Add an interface to limit vma cachingChris Wilson
There is a per-process limit on the number of vma that the process can keep open, so we cannot keep an unlimited cache of unused vma's (besides keeping track of all those vma in the kernel adds considerable overhead). However, in order to work around inefficiencies in the kernel it is beneficial to reuse the vma, so keep a MRU cache of vma. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-12-05intel: Clean up mmaps on freeing the bufferChris Wilson
As a precautionary measure munmap on buffer free so that we never leak the vma. Also include a warning during debugging. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-12-05intel: Unmap buffers during drm_intel_gem_bo_unmapChris Wilson
We cannot afford to cache the vma per open bo as this may exhaust the per-process limits. References: https://bugs.freedesktop.org/show_bug.cgi?id=43075 References: https://bugs.freedesktop.org/show_bug.cgi?id=40066 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2011-10-29intel: Share the implementation of BO unmap between CPU and GTT mappings.Eric Anholt
Before this, consumers of the libdrm API that might map a buffer either way had to track which way was chosen at map time to call the appropriate unmap. This relaxes that requirement by making drm_intel_bo_unmap() always appropriate. Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>

2011-10-28intel: Add an interface for removing relocs after they're added.Eric Anholt
This lets us replace the current inner drawing loop of mesa: for each prim { compute bo list if (check_aperture_space(bo list)) { batch_flush() compute bo list if (check_aperture_space(bo list)) { whine_about_batch_size() fall back; } } upload state to BOs } with this inner loop: for each prim { retry: upload state to BOs if (check_aperture_space(batch)) { if (!retried) { reset_to_last_prim() batch_flush() } else { if (batch_flush()) whine_about_batch_size() goto retry; } } } This avoids having to implement code to walk over certain sets of GL state twice (the "compute bo list" step). While it's not a performance improvement, it's a significant win in code complexity: about -200 lines, and one place to make mistakes related to aperture space instead of N places to forget some BO we should have included. Note how if we do a reset in the new loop , we immediately flush. We don't need to check aperture space -- the kernel will tell us if we actually ran out of aperture or not. And if we did run out of aperture, it's because either the single prim was too big, or because check_aperture was wrong at the point of setting up the last primitive.

2011-10-28intel: Use stdbool.h for dealing with boolean values.Eric Anholt
A few of the bitfield-based booleans are left in place. Changing them to "bool" results in the same code size, so I'm erring on the side of not changing things. Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2010-11-22intel: Compute in-aperture size for relaxed fenced objectsChris Wilson
For relaxed fencing the object may only consume the small set of active pages, but still requires a fence region once bound into the aperture. This is the size we need to use when computing the maximum possible aperture space that could be used by a single batchbuffer and so avoid hitting ENOSPC.

2010-11-09intel: Fix drm_intel_gem_bo_wait_rendering to wait for read-only usage too.Eric Anholt
Both the consumers of this API (sync objects and client throttling) were expecting this behavior. The kernel used to actually behave the desired (but incorrect) way for us anyway, but that got fixed a while back.

2010-11-02intel: Drop silly asserts on mappings present at unmap time.Eric Anholt
The intent of these was to catch mismatched map/unmap. What it actually did was check whether there was ever a mapping of that type (including in a previous life of the buffer through the userland BO cache), not whether they were mismatched. We don't even actually want to catch mismatched map/unmap, unless we also do refcounting, since at one point Mesa would do map/map/use/unmap/unmap. Just remove this code instead.
2010-11-02intel: Remove gratuitous assert on bo_reference.Eric Anholt
This couldn't be triggered except by overflow, since there's an assert in unreference to catch the usual failure of over-unreferencing.

2010-10-29intel: enable relaxed fence allocation for i915Chris Wilson
The kernel has always allowed userspace to underallocate objects supplied for fencing. However, the kernel only allocated the object size for the fence in the GTT and so caused tiling corruption. More recently the kernel does allocate the full fence region in the GTT for an under-sized object and so advertises that clients may finally make use of this feature. The biggest benefit is for texture-heavy GL games on i945 such as World of Padman which go from needing over 1GiB of RAM to play to fitting in the GTT!
