Anyway, moving on to living drivers...

Therefore, this patch adds four new fields to intel_screen which indicate

  max_gl_core_version
  max_gl_compat_version
  max_gl_es1_version
  max_gl_es2_version

The api mask is now correctly set as:

        api_mask |= GLES1;
    if (max_gl_es2_version > 0)

11 years agomesa: Fix default value of BUFFER_ACCESS_FLAGS.
Kenneth Graunke [Sun, 18 Nov 2012 05:23:28 +0000 (21:23 -0800)]
mesa: Fix default value of BUFFER_ACCESS_FLAGS.

According to both the GL 3.0 and ES 3.0 specifications (table 2.7 for GL
and table 2.8 for ES), the default value of BUFFER_ACCESS_FLAGS is
supposed to be zero.

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

egl/wayland: Pull color buffers from dri2_surf->color_buffers pool

We used to keep the color buffers in the dri_buffers array and
swap __DRI_BUFFER_BACK_LEFT and __DRI_BUFFER_FRONT_LEFT around there
and swap third_buffer in in case we needed to triple buffer.  That
gets a little fidgety with all the swaps, so lets use the
color_buffers pool like the gbm platform does.  We track the color buffers,
their corresponding wl_buffer and locked status here and just plug
a free one into dri2_surf->buffers when we need to.

This is a nice clean-up in itself, but it also sets us up to track
buffer age in the color_buffers structs.

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.
