* i965: Reduce passing 2x32b of reloc_domains to 2 bitsChris Wilson2017-08-0423-291/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel only cares about whether the object is to be written to or not, only reduces (reloc.read_domains, reloc.write_domain) down to just !!reloc.write_domain. When we use NO_RELOC, the kernel doesn't even read those relocs and instead userspace has to pass that information in the execobject.flags. We can simplify our reloc api by also removing the unused read/write domains and only pass the resultant flags. The caveat to the above are when we need to make the kernel aware that certain objects need to take into account different work arounds. Previously, this was done using the magic (INSTRUCTION, INSTRUCTION) reloc domains. NO_RELOC requires this to be passed in the execobject flags as well, and now we push that up the callstack. The API is more compact, more expressive of what happens underneath, but unfortunately requires more knowledge of the system at the point of use. Conversely it also means that knowledge is specific and not generally applied and so not overused. text data bss dec hex filename 8502991 356912 424944 9284847 8dacef lib/i965_dri.so (before) 8500455 356912 424944 9282311 8da307 lib/i965_dri.so (after) v2: (by Ken) Rebase.

* i965: Convert reloc.target_handle into an index for I915_EXEC_HANDLE_LUTKenneth Graunke2017-08-041-2/+2
| | | | | | | | | | | | | | | | | | | Based on a patch by Chris Wilson (who also wrote this commit message). Passing the index of the target buffer via the reloc.target_handle is marginally more efficient for the kernel (it can avoid some allocations, and can use a direct lookup rather than a hash or search). It is also useful for ourselves as we can use the index into our exec_bos for other tasks. v2: Only enable HANDLE_LUT if we can use BATCH_FIRST and thereby avoid a post-processing loop to fixup the relocations. v3: Move kernel probing from context creation to screen init. Use batch->use_exec_lut as it more descriptive of what's going on (Daniel) v4: Kernel features already exists, use it for BATCH_FIRST Rename locals to preserve current flavouring v5: Squash in "always insert batch bo first" v6: (by Ken) Split out BATCH_FIRST from HANDLE_LUT.

* i965: Ignore reloc read/write domainsChris Wilson2017-08-041-11/+7
| | | | | | | | | | | | | | | | | | | | | | | | Since before the kernel supported I915_EXEC_NO_RELOC, long before our minimum kernel requirement, the kernel unconditionally invalidated all GPU TLBs before a batch and flushed all GPU caches after a batch. At that moment, the only use for read/write domain was for activity tracking, ensuring that future reads waited for the last writer and future writes waited for all reads. This only requires a single bit in the execbuf interface which can be supplied via the NO_RELOC interface, making the use of relocation domains entirely redundant. Trimming the excess writes into the array allows the compiler to be much more frugal: text data bss dec hex filename 8493790 357184 424944 9275918 8d8a0e i965_dri.baseline 8493758 357184 424944 9275886 8d89ee i965_dri.so (This text improvement really does come from dropping domains, not from the new use of C99 initializers.)

| | | | | | | | | | | | | | Borrow a trick from anv, and use the last known index for the bo to skip a search of the batch->exec_bo when adding a new relocation. In defence against the bo being used in multiple batches simultaneously, we check that this slot exists and points back to us. v2: Also update brw_batch_references() v3: Reset bo->index on creation (Daniel) v4: Improved explanation of bo->index (Kenneth) Signed-off-by: Chris Wilson <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
* i965: Always use the pre-computed offset for the relocation entryChris Wilson2017-08-042-42/+36
| | | | | | | | | | | | | | | | We must be careful to only compute the address once based on the per-context information (rather than accessing the unlocked global bo->offset64) so that the value in the batch does match the reloc.presumed_offset we declare to the kernel. Otherwise, highly unlikely, but we may see GPU hangs in multithreaded users. The only real complication here is isl_surf_fill_state() which needs to adjust the reloc.delta to both general a tile offset and to encode state into the lower 12 bits. (Rebased on ISL changes by Ken.) Reviewed-by: Kenneth Graunke <[email protected]>

* st/mesa: fix handling of NumSamples=1 (v2)Brian Paul2017-08-033-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Mesa we use the convention that if gl_renderbuffer::NumSamples or gl_texture_image::NumSamples is zero, it's a non-MSAA surface. Otherwise, it's an MSAA surface. But in gallium nr_samples=1 is a non-MSAA surface. Before, if the user called glRenderbufferStorageMultisample() or glTexImage2DMultisample() with samples=1 we skipped the search for the next higher number of supported samples and asked the gallium driver to create a surface with nr_samples=1. So we got a non-MSAA surface. This failed to meet the expection of the user making those calls. This patch changes the sample count checks in st_AllocTextureStorage() and st_renderbuffer_alloc_storage() to test for samples > 0 instead of > 1. And we now start querying for MSAA support at samples=2 since gallium has no concept of a 1x MSAA surface. A specific example of this problem is the Piglit arb_framebuffer_srgb-blit test. It calls glRenderbufferStorageMultisample() with samples=1 to request an MSAA renderbuffer with the minimum supported number of MSAA samples. Instead of creating a 4x or 8x, etc. MSAA surface, we wound up creating a non-MSAA surface. Finally, add a comment on the gl_renderbuffer::NumSamples field. There is one piglit regression with the VMware driver: ext_framebuffer_multisample-blit-mismatched-formats fails because now we're actually creating 4x MSAA surfaces (the requested sample count is 1) and we're hitting some sort of bug in the blitter code. That will have to be fixed separately. Other drivers may find regressions too now that MSAA surfaces are really being created. v2: start quering for MSAA support with samples=2 instead of 1.

* i965: Set "Subslice Hashing Mode" to 16x16 on Apollolake.Kenneth Graunke2017-08-022-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of 4.11, the kernel isn't bothering to set the subslice hashing mode on Apollolake, leaving it at the default of 8x8. (It initializes it to 16x4 on most platforms.) Performance data for GPUTest Triangle on Apollolake at 1024x640: X-tiled RT: ----------- 8x8 -> 16x4: 2.4325% +/- 0.383683% (n=107) 8x8 -> 8x4: -3.75105% +/- 0.592491% (n=40) 8x8 -> 16x16: 6.17238% +/- 0.67157% (n=30) Y-tiled RT: ----------- 8x8 -> 16x4: 1.30307% +/- 0.297292% (n=205) 8x8 -> 8x4: -0.769282% +/- 0.729557% (n=35) 8x8 -> 16x16: 3.00254% +/- 0.715503% (n=40) 8x MSAA RT (INTEL_FORCE_MSAA=8): -------------------------------- 8x8 -> 16x4: 1.38889% +/- 0.93729% (n=7) 8x8 -> 8x4: -2.10643% +/- 1.15153% (n=3) 8x8 -> 16x16: 3.87183% +/- 1.08851% (n=5) Based on this, we choose 16x16 for Apollolake. Skylake GT2 with X-tiled buffers appears to be a toss-up between 16x4 and 16x16, and with Y-tiled buffers it doesn't seem to really matter. So we'll leave Skylake alone for now. The hashing mode doesn't seem to make a measurable impact on more complex benchmarks. Acked-by: Matt Turner <[email protected]>
