* i965: Delete tile resource mode codeAnuj Phogat2017-03-275-267/+35
| | | | | | | | | | | Yf/Ys tiling never got used in i965 due to not delivering the expected performance benefits. So, this patch is deleting this dead code in favor of adding it later in ISL when we actually find it useful. ISL can then share this code between vulkan and GL.

* i965: Delete fast copy blit codeAnuj Phogat2017-03-272-185/+48
| | | | | | | | | | | | | | | Fast copy blit was primarily added to support Yf/Ys detiling. But, Yf/Ys tiling never got used in i965 due to not delivering the expected performance benefits. Also, replacing legacy blits with fast copy blit didn't help the benchmarking numbers. This is probably due to a h/w restriction that says "start pixel for Fast Copy blit should be on an OWord boundary". This restriction causes many blit operations to skip fast copy blit and use legacy blits. So, this patch is deleting this dead code in favor of adding it later when we actually find it useful.

* i965: Require Kernel 3.6 for Gen4-5 platforms.Kenneth Graunke2017-03-272-3/+3
| | | | | | | | | | | | | | We've already required Kernel 3.6 on Gen6+ since Mesa 9.2 (May 2013, commit 92d2f5acfadea672417b6785710c9e8b7f605e41). It seems reasonable to require it for Gen4-5 as well, bumping the requirement from 2.6.39. This is necessary for glClientWaitSync with a timeout to work, which is a feature we expose on Gen4-5. Without it, we would fall back to an infinite wait, which is pretty bad. See kernel commit 172cf15d18889313bf2c3bfb81fcea08369274ef in 3.6+. Reviewed-by: Matt Turner <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to Skylake the Gen HW timestamps were driven by a 12.5MHz clock with the convenient property of being able to scale by an integer (80) to nanosecond units. For Skylake the frequency is 12MHz or a scale factor of 83.333333 This updates gen_device_info to track a floating point timebase_scale factor and makes corresponding _queryobj.c changes to no longer assume a scale factor of 80 works across all gens. Although the gen6_ code could have been been left alone, the changes keep the code more comparable, and it now shares a few utility functions for scaling raw timestamps and calculating deltas. The utility for calculating deltas takes into account 32 or 36bit overflow depending on the current kernel version. Note: this leaves the timestamp handling of ARB_query_buffer_object untouched, which continues to use an incorrect scale of 80 on Skylake for now. This is more awkward to solve since the scaling is currently done using a very limited uint64 ALU available to the command parser that doesn't support multiply or divide where it's already taking a large number of instructions just to effectively multiple by 80. This fixes piglit arb_timer_query-timestamp-get on Skylake v2: (Ken) Update timebase_scale for platforms past Skylake/Broxton too.
