15 years agoCELL: fix several stencil problems
Robert Ellison [Fri, 7 Nov 2008 18:29:07 +0000 (11:29 -0700)]
CELL: fix several stencil problems

This small set of changes repairs several different stenciling problems;
now redbook/stencil also runs correctly (and maybe others - I haven't
checked everything yet).

- The number of instructions that had been allocated for fragment ops
  used to be 64 (in cell/common.h).  With complicated stencil use, we
  managed to get up to 93, which caused a segfault before we noticed
  we'd overran our memory buffer.  It's now been bumped to 128,
  which should be enough for even complicated stencil and fragment op
  usage.

- The status of cell surfaces never changed beyond the initial
  PIPE_SURFACE_STATUS_UNDEFINED.  When a user called glClear()
  to clear just the Z buffer (but not the stencil buffer), this caused
  the check_clear_depth_with_quad() function to return false (because
  the surface status was believed to be undefined), and so the device
  was instructed to clear the whole buffer (including the stencil buffer),
  instead of correctly using a quad to clear just the depth, leaving the
  stencil alone.

  This has been fixed similarly to the way the i915 driver handles
  the surface status: during cell_clear_surface(), the status is
  set to PIPE_SURFACE_STATUS_DEFINED.  Then a partial buffer clear is
  handled with a quad, as expected.  Note that we are *not* using
  PIPE_SURFACE_STATUS_CLEAR (also similar to the i915); technically,
  we should be setting the surface status to CLEAR on a clear, and
  to DEFINED when we actually draw something (say on cell_vbuf_draw()),
  but it's difficult to figure out exactly which surfaces are affected
  by a cell_vbuf_draw(), so for now we're doing the easy thing.

- The fragment ops handling was very clever about only pulling out the
  parts of the Z/stencil buffer that it needed for calculations;
  but this failed when only part of the buffer was written, because
  the part that was never pulled out was inadvertently cleared.

  Now all the data from the combined Z/stencil buffer is pulled out,
  just so the proper values can be recombined later and written back
  to the buffer correctly.  As a bonus, the fragment op code generation
  is simplified.

16 years agoFix for 58dc8b7: dest regions must not use HorzStride 0 in ExecSize 1
Keith Packard [Sat, 1 Nov 2008 21:38:19 +0000 (14:38 -0700)]
Fix for 58dc8b7: dest regions must not use HorzStride 0 in ExecSize 1

Quoting section 11.3.10, paragraph 10.2 of the 965PRM:

10.2.  If ExecSize is 1, dst.HorzStride must not be 0. Note that this is
relaxed from rule 10.1.2. Also note that this rule for destination
horizontal stride is different from that for source as stated in
rule #7.

GM45 gets very angry when rule 10.2 is violated.

Patch 58dc8b7 (i965: support destination horiz strides in align1 access mode)
added support for additional horizontal strides in the ExecSize 1 case, but
failed to notice that mesa occasionally re-purposes a register as a
temporary destination, even though it was constructed as a repeating source
with HorzStride = 0.

While, ideally, we should probably fix the code using these register
specifications, this patch simply rewrites them to use HorzStride 1 as the
pre-58dc8b7 code did.
