7 years agoi965: Switch to absolute addressing for constant buffer 0.

i965: Switch to absolute addressing for constant buffer 0.

By default, 3DSTATE_CONSTANT_* Constant Buffer 0 is relative to dynamic
state base address.  This makes it unusable for pushing UBOs.  I'd like
to be able to use all four push buffers.

There is a bit in the INSTPM register (or CS_DEBUG_MODE2 on Skylake)
which controls whether buffer 0 is relative to dynamic state base
address, or simply a normal pointer.  Setting that gives us full
flexibility.

We can't currently write this on Haswell and earlier, and will need
to update the kernel command parser, and then do the whole version
checking song and dance.

framebuffer object by unreferencing the window system draw/read buffers

the context, making sure the reference counts of these buffers will not

i965: Use VALGRIND_MAKE_MEM_x in place of MALLOCLIKE/FREELIKE

Valgrind doesn't actually implement VALGRIND_FREELIKE_BLOCK as the
exact inverse of VALGRIND_MALLOCLIKE_BLOCK. It makes the block
inaccessible, but still leaves it defined in its allocation tracker i.e.
it will report the mmap as lost despite the call to FREELIKE!

Instead of treating the mmap as an allocation, treat it as changing the
access bits upon the memory, i.e. that it becomes defined (because of
the buffer objects always contain valid content from the user's
perspective) upon mmap and inaccessible upon munmap. This makes memcheck
happy without leaving it thinking there is a very large leak.

Finally for consistency, we treat all the mmap/munmap paths the same
even though valgrind can intercept the regular mmap used for GTT. We
could move this in the drm_mmap/drm_munmap macros, but that quickly
looks ugly given the desire for those to support different OSes, but I
didn't try that hard!

i965: Fix asynchronous mappings on !LLC platforms.

When using a read-only CPU mapping, we may encounter stale buffer
contents.  For example, the Piglit primitive-restart test offers the
following scenario:

   1. Read data via a CPU map.
   2. Destroy that buffer.
   3. Create a new buffer - obtaining the same one via the BO cache.
   4. Call BufferSubData, which does a GTT map with MAP_WRITE | MAP_ASYNC.
      (We avoid set_domain for async mappings, so no flushing occurs.)
   5. Read data via a CPU map.
      (Without explicit clflushing, this will contain data from step 1!)

Otherwise, everything ought to work, keeping in mind that we never use
CPU maps for writing - just read-only CPU maps.

This restores the performance gains after Matt's revert in commit
71651b3139c501f50e6547c21a1cdb816b0a9dde.

GL45-CTS.shader_atomic_counters.basic-buffer-operations.  Because async
maps start skipping set-domain, the pread thought everything was nicely
still in the CPU domain, and returned stale data.
