Before this patch, intelInitScreen2 set DRIScreen::api_mask with the hacky
heuristic below:
if (gen >= 3)
api_mask = GL | GLES1 | GLES2;
else
api_mask = 0;
This hack was likely broken on gen2 (i830), but I don't care enough to
properly investigate. It appears that every EGLConfig on i830 has
EGL_RENDERABLE_TYPE=0, and thus eglCreateContext will never succeed.
Anyway, moving on to living drivers...
With the arrival of EGL_OPENGL_ES3_BIT_KHR, this heuristic is now
insufficient. We must enable the GLES3 bit if and only if the driver is
capable of creating a GLES3 context. This requires us to determine the
maximum supported context version supported by the hardware/driver for
each api *during initialization of intel_screen*.
Therefore, this patch adds four new fields to intel_screen which indicate
the maximum supported context version for each api:
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 = GL;
if (max_gl_es1_version > 0)
api_mask |= GLES1;
if (max_gl_es2_version > 0)
api_mask |= GLES2;

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.

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.

These are optimizations which make MSAA a lot faster.
The MSAA work is complete with this commit. (except for enablement of AA
optimizations for RGBA16F, for which a patch is ready and waiting until
the kernel CS checker fix lands)
MSAA can't be made any faster as far as hw programming is concerned.
The catch is only one process and one colorbuffer can use the optimizations
at a time. There usually is only one MSAA colorbuffer, so it shouldn't be
an issue.
Also, there is a limit on the size of MSAA colorbuffer resolution in terms
of megapixels. If the limit is surpassed, the AA optimizations are disabled.
The limit is:
- 1 Mpix on low-end and some mid-level chipsets (1024x768 and 1280x720)
- 2 Mpix on some mid-level chipsets (1600x1200 and 1920x1080)
- 3 or 4 Mpix on high-end chipsets (2048x1536 or 2560x1600, respectively)
It corresponds to the number of raster pipes (= GB pipes) available, each pipe
can hold 1 Mpix of AA compression data.

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.

i965/fs: Don't mix integer/float immediates in i2b handling.
The simulator gets very angry about our i2b code:
cmp.ne(16) g3<1>D g2<0,1,0>D 0F
We can't mix integer DWord and float types. The only reason to use 0F
here was to share code with f2b. Split it and use 0D instead.
While we don't believe anything bad will actually happen because of
this, it's nice to fix the warnings and easy enough to do.

i965: Add an INTEL_DEBUG=no16 option.
Often when debugging, I don't want to see SIMD16 shaders. It makes
INTEL_DEBUG=vs/fs output much easier to read, especially when a program
dumps many shaders. Plus, I also want to verify that SIMD8 works before
even considering SIMD16.
