Ben Widawsky [Wed, 3 Dec 2014 02:33:12 +0000 (18:33 -0800)]
i965: implement ARB_pipeline_statistics_query

NOTE: The implementation was initially one patch, this. All the history is kept
here, even though all the core mesa changes were moved to the parent of this
patch.

This patch implements ARB_pipeline_statistics_query. This addition to GL does
not add a new API. Instead, it adds new tokens to the existing query APIs. The
work to hook up the new tokens is trivial due to it's similarity to the previous
work done for the query APIs. I've implemented all the new tokens to some
degree, but have stubbed out the untested ones at the entry point for Begin().
Doing this should allow the remainder of the code to be left in.

The new tokens give GL clients a way to obtain stats about the GL pipeline.
Generally, you get the number of things going in, invocations, and number of
things coming out, primitives, of the various stages. There are two immediate
uses for this, performance information, and debugging various types of
misrendering. I doubt one can use these for debugging very complex applications,
but for piglit tests, it should be quite useful.

Tessellation shaders, and compute shaders are not addressed in this patch
because there is no upstream implementation. I've implemented how I believe
tessellation shader stats will work for Intel hardware (though there is a bit of
ambiguity). Compute shaders are a bit more interesting though, and I don't yet
know what we'll do there.

For the lazy, here is a link to the relevant part of the spec:

9 years agoi965: Allow exec_list sentinels as arguments to insert functions.
Matt Turner [Wed, 18 Feb 2015 02:01:41 +0000 (18:01 -0800)]
i965: Allow exec_list sentinels as arguments to insert functions.

To insert an instruction at the end of a basic block, we typically do
something like

   inst = block->last_non_control_flow_inst();
   inst->insert_after(block, new_inst);

But blocks can consist of a single control flow instruction, so inst
will actually be the exec_list's head sentinel. We shouldn't use it as
if it were a regular instruction, but it is safe to insert something after
it.

This patch avoids assert-failing because an exec_list sentinel wasn't in
the basic block's instruction list.

and Kill sets each time they enter a new control flow block.  For if
blocks, they also copy the entire existing ACP set contents into the
new set.

When we exit the control flow block, we discard the new sets.  However,
we weren't freeing them - so they lived on until the pass finished.
This can waste a lot of memory (57MB on one pessimal shader).

This patch makes the pass allocate ACP entries using this->acp as the
memory context, and Kill entries out of this->kill.  It also steals
kill entries when moving them from the inner kill list to the parent.

i965: Do Sandybridge workaround flushes before each primitive.

Sandybridge requires the post-sync non-zero workaround in a ton of
places, and if you ever miss one, the GPU usually hangs.

Currently, we try to track exactly when a workaround flush is
necessary (via the brw->batch.need_workaround_flush flag).  This is
tricky to get right, and we've botched it several times in the past.

This patch unconditionally performs the post-sync non-zero flush at the
start of each primitive's state upload (including BLORP).  We drop the
needs_workaround_flush flag, and drop all the other callers, as the
flush has already been performed.

We have no data to indicate that simply flushing all the time will
hurt performance, and it has the potential to help stability.

mesa: implement GL_AMD_pinned_memory

It's not possible to query the current buffer binding, because the extension
doesn't define GL_..._BUFFER__BINDING_AMD.

Drivers should check the target parameter of Drivers.BufferData. If it's

Ben Widawsky [Mon, 16 Feb 2015 04:06:59 +0000 (20:06 -0800)]
i965/simd8vs: Fix SIMD8 atomics

The short version: we need to set bits in R0.7 which provide a mask to be used
for PS kill samples/pixels. Since the VS has no such concept, we just need to
set all 1.

The longer version...
Execution for SIMD8 atomics is defined as follows:
SIMD8: The low 8 bits of the execution mask are ANDed with 8 bits of the
Pixel/Sample Mask from the message header. For the typed messages, the Slot
Group in the message descriptor selects either the low or high 8 bits. For the
untyped messages, the low 8 bits are always selected. The resulting mask is used
to determine which slots are read into the destination GRF register (for read),
or which slots are written to the surface (for write). If the header is not
present, only the low 8 bits of the execution mask are used.

The message header for untyped messages is defined in R0.7 "This field contains
the 16-bit pixel/sample mask to be used for SIMD16 and SIMD8 messages. All 16
bits are used for SIMD16 messages.  For typed SIMD8 messages, Slot Group selects
which 8 bits of this field are used. For untyped SIMD8 messages, the low 8 bits
of this field are used." Furthermore, "The message header for the untyped
messages only needs to be delivered for pixel shader threads, where the
execution mask may indicate pixels/samples that are enabled only due to
derivative (LOD) calculations, but the corresponding slot on the surface must
not be accessed." We're not using a pixel shader here, but AFAICT, this mask is
used for all stages.

This leaves two options, Remove the header, or make the VS code emit the correct
thing for the header. I believe one of the goals of using SIMD8 VS was to get as
much code reuse as possible, and so I chose the latter. Since the VS has no such
thing as kill instructions, the mask is derived simple as all 1's.

meta: Fix saving the results of the current occlusion query

When restoring the current state in _mesa_meta_end it was previously trying to
copy the on-going sample count of the current occlusion query into the new
query after restarting it so that the driver will continue adding to the
previous value. This wouldn't work for two reasons. Firstly, the query might
not be ready yet so the Result member will usually be zero. Secondly the saved
query is stored as a pointer to the query object, not a copy of the struct, so
it is actually restarting the exact same object. Copying the result value is
just copying between identical addresses with no effect. The call to
_mesa_BeginQuery will have always reset it back to zero.

This patch fixes it by making it actually wait for the query object to be
ready before grabbing the previous result. The downside of doing this is that
it could introduce a stall but I think this situation is unlikely so it might
not matter too much. A better solution might be to introduce a real
suspend/resume mechanism to the driver interface. This could be implemented in
the i965 driver by saving the depth count multiple times like it does in the
i945 driver.

Iago Toral Quiroga [Fri, 13 Feb 2015 11:56:26 +0000 (12:56 +0100)]
mesa: Fix element count for byte-swaps in texstore, readpix and texgetimage

Some old format conversion code in pack.c implemented byte-swapping like this:

GLint comps = _mesa_components_in_format(dstFormat);
GLint swapSize = _mesa_sizeof_packed_type(dstType);
if (swapSize == 2)
   _mesa_swap2((GLushort *) dstAddr, n * comps);
else if (swapSize == 4)
   _mesa_swap4((GLuint *) dstAddr, n * comps);

where n is the pixel count. But this is incorrect for packed formats,
where _mesa_sizeof_packed_type is already returning the size of a pixel
instead of the size of a single component, so multiplying this by the
number of components in the format results in a larger element count
for _mesa_swap than we want.

Unfortunately, we followed the same implementation for byte-swapping
in the rewrite of the format conversion code for texstore, readpixels
and texgetimage.

This patch computes the correct element counts for _mesa_swap calls
by computing the bytes per pixel in the image and dividing that by the
swap size to obtain the number of swaps required per pixel. Then multiplies
that by the number of pixels in the image to obtain the swap count that
we need to use.

Also, when handling byte-swapping in texstore_rgba, we were ignoring
the image's depth. This patch fixes this too.
