* i965: Move BRW_NEW_*_PROG_DATA flags to .brw (not .cache).Kenneth Graunke2014-12-021-4/+4
| | | | | | | | | | | | | | | | | | | | | | I put the BRW_NEW_*_PROG_DATA flags at the beginning so that brw_state_cache.c can still continue using 1 << brw_cache_id. I also added a comment explaining the difference between BRW_NEW_*_PROG_DATA and BRW_NEW_*_PROGRAM, as it took me a long time to remember it. Non-mechanical changes: - brw_state_cache.c and brw_ff_gs.c now signal .brw, not .cache. - brw_state_upload.c - INTEL_DEBUG=state changes. - brw_context.h - bit definition merging. v2: Correct the explanation of BRW_NEW_*_PROG_DATA to mention state-based recompiles, and nix the "proper subset" claim, as it's false.

* i965: Rename CACHE_NEW_*_PROG to BRW_NEW_*_PROG_DATA.Kenneth Graunke2014-12-021-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we've moved a bunch of CACHE_NEW_* bits to BRW_NEW_*, the only ones that are left are legitimately related to the program cache. Yet, it seems a bit wasteful to have an entire bitfield for only 7 bits. State upload is one of the hottest paths in the driver. For each atom in the list, we call check_state() to see if it needs to be emitted. Currently, this involves comparing three separate bitfields (mesa, brw, and cache). Consolidating the brw and cache bitfields would save a small amount of CPU overhead per atom. Broadwell, for example, has 57 state atoms, so this small savings can add up. CACHE_NEW_*_PROG covers the brw_*_prog_data structures, as well as the offset into the program cache BO (prog_offset). Since most uses refer to brw_*_prog_data, I decided to use BRW_NEW_*_PROG_DATA as the name. Removing "cache" completely is a bit painful, so I decided to do it in several patches for easier review, and to separate mechanical changes from manual ones. This one simply renames things, and was made via: $ for file in *.[ch]; do sed -i -e 's/CACHE_NEW_\([A-Z_\*]*\)_PROG/BRW_NEW_\1_PROG_DATA/g' \ -e 's/BRW_NEW_WM_PROG_DATA/BRW_NEW_FS_PROG_DATA/g' $file done Note that BRW_NEW_*_PROG_DATA is still in .cache, not .brw! The next patch will remedy this flaw. It will also fix the alphabetization issues.

* i965: Alphabetize brw_tracked_state flags and use a consistent style.Kenneth Graunke2014-11-291-2/+5
| | | | | | | | | | | | | | | | Most of the dirty flags were listed in some arbitrary order. Some used bonus parenthesis. Some put multiple flags on one line, others put one per line. Some used tabs instead of spaces...but only on some lines. This patch settles on one flag per line, in alphabetical order, using spaces instead of tabs, and sheds the unnecessary parentheses. Sorting was mostly done with vim's visual block feature and !sort, although I alphabetized short lists by hand; it was pretty manual.

| | | | | | | | | The "{VS,GS} URB Entry Allocation Size" fields of 3DSTATE_URB allow values in the range 0-4, but they are U8-1 fields, so the range of possible allocation sizes is 1-5. We were erroneously prohibiting a size of 5. Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
* i965/gen7.5: Fix lower bound on number of VS URB entries.Paul Berry2013-09-051-1/+1
| | | | | | | | | | | | Haswell GT2 and GT3 require the number of vertex shader URB entries to be at least 64, not 32. At the moment, we always meet this requirement automatically, because in the absence of a geometry shader, we assign all available URB space to the vertex shader. But when we turn on support for geometry shaders, this lower limit will become important. Reviewed-by: Chad Versace <chad.versace@linux.intel.com>

Surprisingly, this actually removes some code, as functions that use OUT_BATCH don't need to declare "intel"; they just use "brw."

* i965 gen6: Allocate URB space for GSPaul Berry2011-12-071-12/+57
| | | | | | | | | | | | | | When the GS is not in use, the entire URB space is available for the VS. When the GS is in use, we split the URB space 50/50. The 50/50 split is probably not optimal--we'll probably want tune this for performance in a future patch. For example, in most situations, it's probably worth allocating more than 50% of the space to the VS, since VS space is used for vertex caching. But for now this is good enough.

| | | | | | | | | | There will be a little bit of thrashing of the program cache BO as the cache warms up, but once the application is in steady state, this reduces relocations on gen5 and later.

* i965: Allocate the whole URB to the VS and fix calculations for Gen6.Kenneth Graunke2011-04-181-17/+17
| | | | | | | | | | | | | | | | | Since we never enable the GS on Sandybridge, there's no need to allocate it any URB space. Furthermore, the previous calculation was incorrect: it neglected to multiply by nr_vs_entries, instead comparing whether twice the size of a single VS URB entry was bigger than the entire URB space. It also neglected to take into account that vs_size is in units of 128 byte blocks, while urb_size is in bytes. Despite the above problems, the calculations resulted in an acceptable programming of the URB in most cases, at least on GT2.
