Timothy Arceri [Wed, 19 Oct 2016 22:59:00 +0000 (09:59 +1100)]
i965: rewrite brw_setup_vue_interpolation()

Here brw_setup_vue_interpolation() is rewritten not to use the InterpQualifier
array in gl_fragment_program which will allow us to remove it.

This change also makes the code which is only used by gen4/5 more self contained
as it now has its own gen5_fragment_program struct rather than storing the map
in brw_context. This means the interpolation map will only get processed once
and will get stored in the in memory cache rather than being processed everytime
the fs changes.

Also by calling this from the fs compile code rather than from the upload code
and using the interpolation assigned there we can get rid of the
BRW_NEW_INTERPOLATION_MAP flag.

It might not seem ideal to add a gen5_fragment_program struct however by the end
of this series we will have gotten rid of all the brw_{shader_stage}_program
structs and replaced them with a generic brw_program struct so there will only
be two program structs which is better than what we have now.

V2: Don't remove BRW_NEW_INTERPOLATION_MAP from dirty_bit_map until the following
patch to fix build error.

V3 - Suggestions by Jason:
- name struct gen4_fragment_program rather than gen5_fragment_program
- don't use enum with memset()
- create interp mode set helper and simplify logic to call it
- add assert when calling function to show prog will never be NULL for

Eduardo Lima Mitev [Tue, 25 Oct 2016 08:20:12 +0000 (10:20 +0200)]
vulkan/wsi/x11: Fix behavior of vkGetPhysicalDeviceSurfaceFormatsKHR

x11_surface_get_formats() is currently asserting that the number of
elements in pSurfaceFormats must be greater than or equal to the number
of formats available. This is buggy because pSurfaceFormatsCount
elements are later copied from the internal formats' array, so if
pSurfaceFormatCount is greater, it will overflow it.

On top of that, this assertion violates the spec. From the Vulkan 1.0
(revision 32, with KHR extensions), page 579 of the PDF:

    "If pSurfaceFormats is NULL, then the number of format pairs supported
     for the given surface is returned in pSurfaceFormatCount. Otherwise,
     pSurfaceFormatCount must point to a variable set by the user to the
     number of elements in the pSurfaceFormats array, and on return the
     variable is overwritten with the number of structures actually written
     to pSurfaceFormats. If the value of pSurfaceFormatCount is less than
     the number of format pairs supported, at most pSurfaceFormatCount
     structures will be written. If pSurfaceFormatCount is smaller than
     the number of format pairs supported for the given surface,
     VK_INCOMPLETE will be returned instead of VK_SUCCESS to indicate that
     not all the available values were returned."

So, the correct behavior is: if pSurfaceFormatCount is greater than the
internal number of formats, it is clamped to that many formats. But
if it is lesser than that, then pSurfaceFormatCount elements are copied,
and the call returns VK_INCOMPLETE.

Post-splitting, VGRFs have a maximum size (MAX_VGRF_SIZE).  This is

each size of VGRF.

We can (and do) allocate virtual registers larger than MAX_VGRF_SIZE,
but we must ensure that they are splittable.  split_virtual_grfs()
asserts that the post-splitting register size is in range.

Unfortunately, these trip for completely dead registers which are too
large - we only set split points for live registers.  So dead ones are
never split, and if they happened to be too large, they'd trip asserts.

To fix this, call compact_virtual_grfs() to eliminate dead registers
before splitting.

st/mesa: cleanup and fix primitive restart for indirect draws

There are three intended functional changes here:

1. OpenGL 4.5 clarifies that primitive restart should only apply with index
   buffers, so make that change explicit in the indirect draw path.

2. Make PrimitiveRestartFixedIndex work with indirect draws.

3. The change where primitive_restart is only set when the restart index can
   actually have an effect (based on the size of indices) is also applied for
   indirect draws.

8 years agoglsl/mesa: remove unused namespace support from the symbol table

glsl/mesa: remove unused namespace support from the symbol table

Namespace support seems to have been unused for a very long time.

Previously the hash table entry was never removed and the symbol name
wasn't freed until the symbol table was destroyed.

In theory this could reduced the number of times we need to copy a string
as duplicate names are reused. However in practice there is likely only a
limited number of symbols that are the same and this is likely to cause
other less than optimal behaviour such as the hash_table continuously
growing.

Along with dropping namespace support this change removes entries from
the hash table as they become unused.

shared glapi was previously built without setting CFLAGS for

The x86 and sparc assembly versions of the dispatch table partially

"Interface Blocks":

"Matched block names within a shader interface (as defined above) must

 sequence of types and the same sequence of member names, as well as
