* tgsi: fix out of bounds access in exec_atomop()Samuel Pitoiset2016-04-011-1/+1
| | | | | | | | | The number of channels must be 4 for all RGBA components. Fixes: 22d129601 ("tgsi: add support for image operations to tgsi_exec. (v2.1)") Signed-off-by: Samuel Pitoiset <[email protected]> Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Dave Airlie <[email protected]>
* tgsi: split tgsi_util_get_texture_coord_dim() function into twoBrian Paul2016-03-316-47/+46
| | | | | | | | | | | | | | | It was kind of overloaded, returning two different things. Now get the index of the shadow reference src register with a new tgsi_util_get_shadow_ref_src_index() function. To verify the new code, I added some temp/debug code which looped over all TGSI_TEXTURE_x values, calling the old function and new and checking that the returned indexes matched. Also tested piglit "shadow" tests with softpipe/llvmpipe. No testing of ilo and radeonsi changes. Reviewed-by: Dave Airlie <[email protected]>

* nv50/ir: Check for valid insn instead of def sizePierre Moreau2016-03-311-2/+2
| | | | | | | | | | | | | This fixes a null pointer dereference during the register allocation pass, if a function had arguments. Functions arguments get a definition from the function itself, a definition which is therefore not linked to any instruction. If a value ends up having a definition but no linked instruction, the register allocation pass doesn't need to consider whether that value is generated by an instruction that can only handle "short" registers (on nv50).

| | | | | | | | | | | Instead of removing every instruction in add_insts_from_block(), just move the instruction to its scheduled location. This is a step towards doing both bottom-up and top-down scheduling without conflicts.

| | | | | | | | | | | | | | | | | | | | | | I think when this code was written, basic blocks were always ended by a control flow instruction or an end-of-thread message. That's no longer the case, and removing this restriction actually helps things: instructions in affected programs: 7267 -> 7244 (-0.32%) helped: 4 total cycles in shared programs: 66559580 -> 66431900 (-0.19%) cycles in affected programs: 28310152 -> 28182472 (-0.45%) helped: 9577 HURT: 879 GAINED: 2 The addition of the is_control_flow() checks is not a functional change, since the add_insts_from_block() does not put them in the list of instructions to schedule.

* Revert "i965: Don't add barrier deps for FB write messages."Matt Turner2016-03-301-4/+3
| | | | | | | | | | | | | | This reverts commit d0e1d6b7e27bf5f05436e47080d326d7daa63af2. The change in the vec4 code is a mistake -- there's never an FS_OPCODE_FB_WRITE in vec4 code. The change in the fs code had the (harmless) effect of not recognizing an FB_WRITE as a scheduling barrier even if it was marked EOT -- harmless because the scheduler marked the last instruction of a block as a barrier, something I'm changing in the following patches. This will be reimplemented later in the series.

| | | | | | | | | | | | | | | | | | This enables in shader defined transform feedback mode even if the only place xfb_stride is defined is on the global out. We don't worry about xfb_buffer since Issue 22 c) in the spec says: "If the shader has an "xfb_buffer" qualifier identifying a buffer, but doesn't declare "xfb_offset" on anything associated with it, what happens? ... variables not qualified with "xfb_offset" are not captured, which makes the associated "xfb_buffer" qualifier irrelevant."

| | | | | | | | | | | | | | | | From the ARB_enhanced_layous spec: "It is a compile-time or link-time error to have any *xfb_offset* that overflows *xfb_stride*, whether stated on declarations before or after the *xfb_stride*, or in different compilation units. ... When no *xfb_stride* is specified for a buffer, the stride of a buffer will be the smallest needed to hold the variable placed at the highest offset, including any required padding."

* glsl: validate global out xfb_stride qualifiers and set stride on empty buffersTimothy Arceri2016-03-314-0/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here we use the built-in validation in ast_layout_expression::process_qualifier_constant() to check for mismatching global out strides on buffers in a single shader. From the ARB_enhanced_layouts spec: "While *xfb_stride* can be declared multiple times for the same buffer, it is a compile-time or link-time error to have different values specified for the stride for the same buffer." For intrastage validation a new helper link_xfb_stride_layout_qualifiers() is created. We also take this opportunity to make sure stride is at least a multiple of 4, we will validate doubles at a later stage. From the ARB_enhanced_layouts spec: "If the buffer is capturing any double-typed outputs, the stride must be a multiple of 8, otherwise it must be a multiple of 4, or a compile-time or link-time error results." Finally we update store_tfeedback_info() to apply the strides to LinkedTransformFeedback and update the buffers bitmask to mark any global buffers with a stride as active. For example a shader with: layout (xfb_buffer = 0, xfb_offset = 0) out vec4 gs_fs; layout (xfb_buffer = 1, xfb_stride = 64) out; Is expected to have a buffer bound to both 0 and 1. From the ARB_enhanced_layouts spec: "A binding point requires a bound buffer object if and only if its associated stride in the program object used for transform feedback primitive capture is non-zero."
