  max_gl_core_version
  max_gl_compat_version

Note that there are two related quantities: the obsolete BUFFER_ACCESS
enum and the new BUFFER_ACCESS_FLAGS bitfield.

BUFFER_ACCESS can only be GL_READ_ONLY, GL_WRITE_ONLY, or GL_READ_WRITE;
BUFFER_ACCESS_FLAGS can easily represent all three via GL_MAP_WRITE_BIT,
GL_MAP_READ_BIT, and their logical or.  It also supports more flags.

Thus, Mesa only stores the bitfield, and simply computes the old enum
when queried, via simplified_access_mode(bufObj->AccessFlags).

The tricky part is that, while BUFFER_ACCESS_FLAGS defaults to 0,
BUFFER_ACCESS defaults to GL_READ_WRITE for desktop [GL 3.0, table 2.8]
and GL_WRITE_ONLY_OES for ES [the GL_EXT_map_buffer_range extension].

Mesa tried to implement this by setting the default AccessFlags to
GL_MAP_READ_BIT | GL_MAP_WRITE_BIT on desktop, and GL_MAP_WRITE_BIT on
ES.  But in all specifications, it needs to be 0.

This patch moves that logic into simplified_access_mode(): when
AccessFlags == 0, it now returns GL_READ_WRITE for desktop and
GL_WRITE_ONLY for ES 1/2.  (BUFFER_ACCESS doesn't exist on ES 3.0,
so it's irrelevant there.)

With that in place, it changes the AccessFlags default to 0.

Fixes three es3conform tsets:
- copy_buffer_defaults
- map_buffer_range_modify_indices
- pixel_buffer_object_default_parameters

mesa: Rework crazy error code rules in glDrawBuffers().

Perhaps most importantly, this patch adds comments quoting the relevant
spec paragraphs above each error condition.

It also makes three changes:
- For FBOs, GL_COLOR_ATTACHMENTm where m >= MaxDrawBuffers is supposed
  to generate INVALID_OPERATION (not INVALID_ENUM).
- Constants that refer to multiple buffers (such as FRONT, BACK, LEFT,
  RIGHT, and FRONT_AND_BACK) are supposed to generate INVALID_OPERATION,
  not INVALID_ENUM.
- In ES 3.0, for FBOs, buffers[i] must be NONE or GL_COLOR_ATTACHMENTi
  or else INVALID_OPERATION occurs.  (This is a new restriction.)

Fixes es3conform's draw-buffers-api test.

v2: The error path was missing a "return" like all the other error
paths.  Also, we may as well call it glDrawBuffers in the error message
since the ARB suffix doesn't exist in ES 3.

The limit is:

i965: Avoid blending with destination alpha when RB format has no alpha bits

The hardware does not support a render target without an alpha channel.
So when the user creates a render buffer with no alpha channel, there actually
is storage available for alpha internally. It requires special care to
avoid these unwanted alpha bits from causing any problems.

11 years agoi965: Move program_id to intel_screen instead of brw_context.
Kenneth Graunke [Wed, 9 Jan 2013 01:00:13 +0000 (17:00 -0800)]
i965: Move program_id to intel_screen instead of brw_context.

According to bug #54524, I regressed oglconform's multicontext test
when I reenabled the fragment shader precompile.

However, these test cases only passed by miraculous coincedence.  We
assign each fragment program a unique ID (brw_fragment_program::id which
becomes brw_wm_prog_key::program_string_id) which we obtain by storing a
per-context counter.

The test case uses GLX context sharing to access the same fragment
program from two different contexts.  This means that we share a program
cache.  Before the precompile, if both contexts happened to use the same
shaders in the same order, we'd obtain the same program_string_ids (by
virtue of doing the same computation twice).  However, the more likely
scenario is that they completely disagree on program_string_id.

This meant that we'd have two completely different fragment shaders in
the cache with the same ID, tricking us to think they were the same
(aside from NOS), so we'd render using the wrong program.

This patch implements a simple fix suggested by Eric: it moves the
global counter out of brw_context and into intel_screen, which is shared
across all contexts.  A mutex protects it from concurrent access.

This is also the first direct usage of pthreads in the i965 driver.

Fixes 10 subcases of oglconform's multicontext test.

i965: Fix build error with clang.

Technically, variable sized arrays are a required feature of C99,

Gcc allows using them in C++ unless you specify -pedantic, and Clang
