Iago Toral Quiroga 88b539c4a0 anv: do not try to ref/unref NULL shaders
This situation can happen if we failed to allocate memory for the shader.

v2:
 - We shouldn't see NULL shaders in anv_shader_bin_ref so we should not check
   for that (Jason). Make sure that callers don't attempt to call this
   function with a NULL shader and assert that this never happens (Iago).

v3:
 - All callers to anv_shader_bin_unref seem to check for NULL before calling,
   so just assert that it is not NULL (Topi)

Gregory Hainaut 93bdad3253 mesa/glthread: restore the dispatch table when incompatible gl calls are detected
While a context only has a single glthread, the context itself can be
attached to several threads. Therefore the dispatch table must be
updated in all threads before the destruction of glthread. In others
words, glthread can only be destroyed safely when the context is deleted.

Fixes remaining crashes in the glx-multithread-makecurrent* tests.

V2: (Timothy Arceri) updated gl_API.dtd marshal_fail description.

We want to support glthread on GLES contexts with reasonable apps, and on

The threading for GL core is in place, but there are so few applications
actually using a core GL context that it would be nice to extend support
back.  However, some of the features of compat GL (particularly user

able to disable threading when we discover that the app is using them.

This patch splits the context's CurrentDispatch pointer into two

when doing multithread marshalling, we can distinguish between the
dispatch table that's being used by the client (to serialize GL calls
into the marshal buffer) and the dispatch table that's being used by
the server (to execute the GL calls).

will be immediate user data, or will be loaded from a PBO.  The normal
teximage functions will be sync by default because they don't know up

Paul Berry f5052f45a2 glapi: Annotate functions with "marshal" attribute.
Several API functions require special treatment in order to be marshalled
to a background thread.  Others can't be safely executed in a background
thread and need to be executed synchronously (e.g. since they return data
through a pointer argument).

This annotation will be used when code generating thread marshalling code,
to ensure that each function is marshalled in the correct way.

Note that PixelMap functions are marked as synchronous for now since
their pointer may be relative to buffer on the GPU, so we'll need
special logic to marshal them properly.

v2: Move description of attribute types to a comment in the dtd file.

Francisco Jerez e6469ec43b gallium/tgsi: Treat UCMP sources as floats to match the GLSL-to-TGSI pass expectations.
Currently the GLSL-to-TGSI translation pass assumes it can use
floating point source modifiers on the UCMP instruction.  See the bug
report linked below for an example where an unrelated change in the
GLSL built-in lowering code for atan2 (e9ffd12827)
caused the generation of floating-point ir_unop_neg instructions
followed by ir_triop_csel, which is translated into UCMP with a negate
modifier on back-ends with native integer support.

Allowing floating-point source modifiers on an integer instruction
seems like rather dubious design for a transport IR, since the same
semantics could be represented as a sequence of MOV+UCMP instructions
instead, but supposedly this matches the expectations of TGSI
back-ends other than tgsi_exec, and the expectations of the DX10 API.
I take no responsibility for future headaches caused by this
inconsistency.

Fixes a regression of piglit glsl-fs-tan-1 on softpipe introduced by
the above-mentioned glsl front-end commit.  Even though the commit
that triggered the regression doesn't seem to have made it to any
stable branches yet, this might be worth back-porting since I don't
see any reason why the bug couldn't have been reproduced before that
point.

Grazvydas Ignotas eb5a61f77a util/disk_cache: do eviction before creating .tmp
cache_put() first creates a .tmp file and then tries to do eviction.
The recently added LRU eviction code selects non-empty directory with
the oldest access time, but that may easily be the one with just the
new .tmp file, especially on Linux where atime is updated lazily
(with "relatime" mount option, which is the default). So when cache is
small, if random doesn't hit another dir LRU keeps selecting the same
dir with just the .tmp and not deleting anything. To fix this (and the
tests), do eviction earlier.

Ben Widawsky 63bd2ae745 gbm: Introduce modifiers into surface/bo creation
The idea behind modifiers like this is that the user of GBM will have
some mechanism to query what properties the hardware supports for its BO
or surface. This information is directly passed in (and stored) so that
the DRI implementation can create an image with the appropriate
attributes.

A getter() will be added later so that the user GBM will be able to
query what modifier should be used.

Only in surface creation, the modifiers are stored until the BO is
actually allocated. In regular buffer allocation, the correct modifier
can (will be, in future patches be chosen at creation time.

v2: Make sure to check if count is non-zero in addition to testing if
calloc fails. (Daniel)

v3: Remove "usage" and "flags" from modifier creation. Requested by
Kristian.

v4: Take advantage of the "INVALID" modifier added by the GET_PLANE2
series.

v5: Don't bother with storing modifiers for gbm_bo_create because that's
a synchronous operation and we can actually select the correct modifier
at create time (done in a later patch) (Jason)

v6: Make modifier condition outside the check so that dri_use will work
properly (Jason)
