2011-02-15r300g: offload the CS ioctl to another threadMarek Olšák
This is a multi-threading optimization which hides the kernel overhead behind a thread. It improves performance in CPU-limited apps by 2-15%. Of course you must have at least 2 cores for it to make any difference. It can be disabled with: export RADEON_THREAD=0
2011-02-15r300g: actually implement the is_buffer_busy hook the right wayMarek Olšák
Ooops.
2011-02-15r300g: handle interaction between UNSYNCHRONIZED and DONTBLOCK flags in bo_mapMarek Olšák
The VBO module uses both, but they are somewhat opposite to each other. In this case, we pick UNSYNCHRONIZED and ignore DONTBLOCK.
2011-02-15r300g: fix a possible race condition when mapping a bufferMarek Olšák
This is the last one I think.
2011-02-14r300g: flush CS in bo_map even if we get USAGE_DONTBLOCKMarek Olšák
Because an app may do something like this: while (!(ptr = bo_map(..., DONT_BLOCK))) { /* Do some other work. */ } And it would be looping endlessly if we didn't flush.

2011-02-13r300g: fixup the handle_compare functionMarek Olšák

2011-02-12r300g: typecast void* to unsigned correctlyMarek Olšák
2011-02-12r300g: improve function radeon_bo_is_referenced_by_csMarek Olšák
This should prevent calling into radeon_get_reloc when there's only one context.
2011-02-11r300g: remove unused function prototypes, update copyrightMarek Olšák
2011-02-11r300g: plug a memory leak in winsysMarek Olšák
2011-02-11r300g: remove unneeded code in winsysMarek Olšák
We don't need the read/write flags.
2011-02-11r300g: import the last bits of libdrm and cleanup the whole thingMarek Olšák
Based on Dave's branch. The majority of this commit is a cleanup, mainly renaming things. There wasn't much code to import, just ioctl calls. Also done: - implemented unsynchronized bo_map (important optimization!) - radeon_bo_is_referenced_by_cs is no longer a refcount hack - dropped the libdrm_radeon dependency I'm surprised that this has resulted in less code in the end.

2011-01-27r300g: print driver info if RADEON_DEBUG=infoMarek Olšák
2011-01-27r300g: add winsys flag CAN_AACOMPRESSMarek Olšák

2011-01-08r300g: rework command submission and resource space checkingMarek Olšák
The motivation behind this rework is to get some speed by reducing CPU overhead. The performance increase depends on many factors, but it's measurable (I think it's about 10% increase in Torcs). This commit replaces libdrm's radeon_cs_gem with our own implemention. It's optimized specifically for r300g, but r600g could use it as well. Reloc writes and space checking are faster and simpler than their counterparts in libdrm (the time complexity of all the functions is O(1) in nearly all scenarios, thanks to hashing). (libdrm's radeon_bo_gem is still being used in the driver.) It works like this: cs_add_reloc(cs, buf, read_domain, write_domain) adds a new relocation and also adds the size of 'buf' to the used_gart and used_vram winsys variables based on the domains, which are simply or'd for the accounting purposes. The adding is skipped if the reloc is already present in the list, but it accounts any newly-referenced domains. cs_validate is then called, which just checks: used_vram/gart < vram/gart_size * 0.8 The 0.8 number allows for some memory fragmentation. If the validation fails, the pipe driver flushes CS and tries do the validation again, i.e. it validates only that one operation. If it fails again, it drops the operation on the floor and prints some nasty message to stderr. cs_write_reloc(cs, buf) just writes a reloc that has been added using cs_add_reloc. The read_domain and write_domain parameters have been removed, because we already specify them in cs_add_reloc. The space checking has been tested by putting small values in vram/gart_size variables.

2010-12-22r300g: support B10G10R10A2 render targets only with DRM 2.8.0 or later versionsMarek Olšák
2010-12-05r300g: cleanup winsysMarek Olšák
2010-12-03r300g: use internal BO handle for add_buffer and write_relocMarek Olšák
Small perf improvement in ipers. radeon_drm_get_cs_handle is exactly what this commit tries to avoid in every write_reloc.
2010-11-25r300g/r600g: bump cache manager timeouts to 1sDave Airlie
On lightsmark on my r500 this drop the bufmgr allocations of the sysprof.

2010-09-24r300g: make accessing map_list and buffer_handles thread-safeMarek Olšák
NOTE: This is a candidate for the 7.9 branch.
2010-09-24r300g: fixup long-lived BO maps being incorrectly unmapped when flushingMarek Olšák
Based on commit 3ddc714b20ac4e28b80c6f88d1993445fff2262c by Dave Airlie. NOTE: This is a candidate for the 7.9 branch.
2010-09-15r300g: fix buffer reuse issue caused by previous commitDave Airlie
caused by 0b9eb5c9bb03e5134d9a41786178100109e80c5a test run glxgears, resize.
2010-09-15r300g: prevent creating multiple winsys BOs for the same handleMarek Olšák
This fixes a DRM deadlock in the cubestorm xscreensaver, because somehow there must not be 2 different BOs relocated in one CS if both BOs back the same handle. I was told it is impossible to happen, but apparently it is not, or there is something else wrong.
2010-09-13r300g: fix map_bufferMarek Olšák
https://bugs.freedesktop.org/show_bug.cgi?id=30145
2010-09-12pb: add void * for flush ctx to mapping functionsDave Airlie
If the buffer we are attempting to map is referenced by the unsubmitted command stream for this context, we need to flush the command stream, however to do that we need to be able to access the context at the lowest level map function, currently we set the buffer in the toplevel map, but this racy between context. (we probably have a lot more issues than that.) I'll look into a proper solution as suggested by jrfonseca when I get some time.

2010-08-08r300g: generalize the way we ask for hyperzMarek Olšák
This makes it compatible with the modified DRM interface in drm-radeon-testing. Also, now you need to set RADEON_HYPERZ=1 to be able to use hyperz. It's not bug-free yet.
2010-08-06r300g: do not emit GB_Z_PEQ_CONFIG on non-r500 if DRM < 2.6.0Marek Olšák
2010-08-05r300g: debug_print on startup whether we can use hyper-zMarek Olšák
2010-08-05r300g: implement hyper-z support. (v4)Dave Airlie
This implements fast Z clear, Z compression, and HiZ support for r300->r500 GPUs. It also allows cbzb clears when fast Z clears are being used for the ZB. It requires a kernel with hyper-z support. Thanks to Marek Olšák <maraeo@gmail.com>, who started this off, and Alex Deucher at AMD for providing lots of hints. v2: squashed zmask ram size fix] squashed r300g/blitter: fix Z readback when compressed] v3: rebase around texture changes in master - .1 fix more bits v4: migrated to using u_mm in r300_texture to manage hiz/zmask rams consistently disabled HiZ when using OQ flush z-cache before turning hyper-z off update hyper-z state on dsa state change store depthclearvalue across cbzb clears and replace it afterwards. Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-07-25r300g: reject resources from handles which are not large enoughMarek Olšák
The driver gets a buffer and its size in resource_from_handle. It computes the required minimum buffer size from given texture properties, and compares the two sizes. This is to early detect DDX bugs.
2010-07-16r300g: do not make copies of constant buffers, emit them directlyMarek Olšák
2010-07-16r300g: rebuild winsys and command submission to support multiple contextsMarek Olšák
2010-07-10r300g: do not print a rejected CS if RADEON_DUMP_CS is not setMarek Olšák
Also print relocation failures on non-debug builds too.
2010-07-08r300g: store/return the stride for winsys_handle in winsysMarek Olšák
2010-06-30r300g: move one flush from winsys to the contextMarek Olšák
This flush happens when changing the tiling flags, and it should really be done in the context. I hope this fixes FDO bug #28630.

2010-06-20r300g: cleanup buffer_{from, get}_handleMarek Olšák
2010-06-14r300g: drop begin_cs/end_csMarek Olšák
I have had a look at the libdrm sources and they just contain more or less the same checking we do in macros, and begin_cs may realloc the CS buffer if we overflow it, which never happens with r300g. So these are pretty much useless. There is a small but measurable performance increase by dropping the two functions.
