Each driver (i830, i915, i965) used independent but similar code to
validate the requested context version. With the rececnt arrival of GLES3,
that logic has needed an update. Rather than apply identical updates to
each drivers validation code, let's just move the validation into the
shared routine intelInitContext.
This refactor required some incidental changes to functions
i830CreateContext and intelInitContext. For each function, this patch:
- Adds context version parameters to the signature.
- Adds a DRI_CTX_ERROR out param to the signature.
- Sets the DRI_CTX_ERROR at each early return.
Tested against gen6 with piglit egl-create-context-verify-gl-flavor.
Verified that this patch does not change the set of exposed EGL context
flavors.

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;
Tested against gen6 with piglit egl-create-context-verify-gl-flavor.
Verified that this patch does not change the set of exposed EGL context
flavors.

- Replace the if-tree on gen with a switch, for Ian.

- Drop ES2 version back to 2.0 due to rebase (Ian).

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.

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

The specification requires that query results are processed in order, (when

This allows for avoiding the occlusion query erroneously accumulating results
during the meta operation. This functionality is made conditional on a new

since glClear is specified to not generate fragments.

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.
If it's enabled, the driver prints to stdout:
radeon: Acquired access to AA optimizations.

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.
Specifically, when blending, and when the blend factors would read the
destination alpha values, this commit coerces the blend factors to instead be
either 0 or 1 as appropriate.

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.
