* i965: Add QWORD sizes to type_sz macroBen Widawsky2015-01-201-0/+3
| | | | | | | | | | | | | | | | | | | GEN8 added the QWORD as a valid type for certain operations on the EU. In order to calculate the number of registers used one must have the type size as part of the equation. Quoting the formula in the code: regs_written = (dst.width * dst.stride * type_sz(dst.type) + 31) / 32; Adding this separately for bisection since there is no simple way to add an assert in the type_sz function. NOTE: As a side note, I was confused for a while because it's impossible to calculate the region, ie. registers needed, without vstride. However, at this point these are all part of the IR, and so no vstride must exist.

* i965: Work around mysterious Gen4 GPU hangs with minimal state changes.Kenneth Graunke2015-01-191-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gen4 hardware appears to GPU hang frequently when using Chromium, and also when running 'glmark2 -b ideas'. Most of the error states contain 3DPRIMITIVE commands in quick succession, with very few state packets between them - usually VERTEX_BUFFERS/ELEMENTS and CONSTANT_BUFFER. I trimmed an apitrace of the glmark2 hang down to two draw calls with a glUniformMatrix4fv call between the two. Either draw by itself works fine, but together, they hang the GPU. Removing the glUniform call makes the hangs disappear. In the hardware state, this translates to removing the CONSTANT_BUFFER packet between the two 3DPRIMITIVE packets. Flushing before emitting CONSTANT_BUFFER packets also appears to make the hangs disappear. I observed a slowdown in glxgears by doing it all the time, so I've chosen to only do it when BRW_NEW_BATCH and BRW_NEW_PSP are unset (i.e. we haven't done a CS_URB_STATE change or already flushed the whole pipeline). I'd much rather understand the problem, but at this point, I don't see how we'd ever be able to track it down further. We have no real tools, and the hardware people moved on years ago. I've analyzed 20+ error states and read every scrap of documentation I could find.

* i965/nir: Replace fs_reg(GRF, virtual_grf_alloc(...)) with vgrf(...).Kenneth Graunke2015-01-193-13/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | brw_fs_nir.cpp creates almost all of its registers via: fs_reg reg = fs_reg(GRF, virtual_grf_alloc(num_components)); When we add SIMD16 support, we'll need to set reg->width = 16 and double the VGRF size...on pretty much every VGRF it allocates. This patch replaces that pattern with a new "vgrf" helper method: fs_reg reg = vgrf(num_components); The new function correctly takes reg_width into account. For now, reg_width is always 1, so this should have no functional change. v2: Just make vgrf() account for reg_width right away, rather than changing the behavior in the next patch. v3: Replace one last virtual_grf_alloc I missed. It's used in code that only runs for dispatch_width == 8, so it doesn't matter, but consistency is nice.

| | | | | | | | | | | | | | | | | | I dislike how fs_reg has a constructor that knows about fs_visitor. Apart from that, it stands alone, with no need to interact with the rest of the compiler. Which is sensible - a class that represents a register should do just that. Allocating virtual register numbers should be left up to the compiler (fs_visitor). This patch replaces the constructor with a new fs_visitor::vgrf method, eliminating fs_reg's dependency on fs_visitor. It ends up being no more code. v2: Rebase from May 2014 -> January 2015.

Trying to substitute real shaders with the dummy shader would crash when trying to upload non-existent uniforms. Say there are none. It also wouldn't generate any code because we didn't compute the CFG, and code generation now requires it. Compute it. Gen4-5 also require a message header to be present. On Gen6+, there were assertion failures in SF/SBE state because urb_setup was memset to 0 instad of -1, causing it to think there were attributes when nothing was set up right. Set to no attributes. Finally, you have to ensure "Setup URB Entry Read Length" is non-zero or you get GPU hangs, at least on Crestline. It now works on at least Crestline and Haswell.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't actually have the code for the shader cache just yet, but this configure machinery puts everything in place so that the shader cache can be optionally compiled in. Specifically, if the user passes no option (neither --disable-shader-cache, nor --enable-shader-cache), then this feature will be automatically detected based on the presence of a usable SHA-1 library. If no suitable library can be found, then the shader cache will be automatically disabled, (and reported in the final output from configure). The user can force the shader-cache feature to not be compiled, (even if a SHA-1 library is detected), by passing --disable-shader-cache. This will prevent the compiled Mesa libraries from depending on any library for SHA-1 implementation. Finally, the user can also force the shader cache on with --enable-shader-cache. This will cause configure to trigger a fatal error if no sutiable SHA-1 implementation can be found for the shader-cache feature.

The caller can first save the current offset, write a placeholder uint32, write out (and count) the items, then use blob_overwrite_uint32 with the saved offset to replace the placeholder value. Then, when deserializing, the reader will first read the count and know how many subsequent items to expect.

| | | | | | | | | | | | | | | This new interface allows for writing a series of objects to a chunk of memory (a "blob").. The allocated memory is maintained within the blob itself, (and re-allocated by doubling when necessary). There are also functions for reading objects from a blob as well. If code attempts to read beyond the available memory, the read functions return 0 values (or its moral equivalent) without reading past the allocated memory. Once the caller is done with the reads, it can check blob->overrun to ensure whether any invalid values were previously returned due to attempts to read too far.

* mesa: Add iterate method for string_to_uint_mapTapani Pälli2015-01-161-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | The upcoming shader cache needs this to be able to cache hash data from the gl_shader_program structure. Edited-by: Carl Worth <[email protected]>: There is an internal implementation detail that the hash table underlying the struct string_to_uint_map stores each value internally as (value+1). The user needn't be very concerned with this (other than knowing that a value of UINT_MAX cannot be stored) since put() adds 1 and get() subtracts 1. So in this commit, rather than call the user's function directly with hash_table_call_foreach, we call through a wrapper that fixes up the off-by-one values before the caller's callback sees them. And with this wrapper in place, we also give a better signature to the callback function being passed to iterate(), so that this callback function can actually expect a char* and an unsigned argument, (rather than a couple of void* ).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When converting to a format that has fewer bits the previous code was just shifting off the bits. This doesn't provide very accurate results. For example when converting from 8 bits to 5 bits it is equivalent to doing this: x * 32 / 256 This works as if it's taking a value from a range where 256 represents 1.0 and scaling it down to a range where 32 represents 1.0. However this is not correct because it is actually 255 and 31 that represent 1.0. We can do better with a formula like this: (x * 31 + 127) / 255 The +127 is to make it round correctly. The new code has a special case to use uint64_t when the result of the multiplication would overflow an unsigned int. This function is inline and only ever called with constant values so hopefully the if statements will be folded. The main incentive to do this is to make the CPU conversion path pick the same values as the hardware would if it did the conversion.

| | | | | | | | | | | | | | | | | | Rendering with a GS and then using transform feedback with a program that does not have a GS can crash in gen6. The reason for this is that brw_begin_transform_feedback checks brw->geometry_program to decide if there is a GS program, but this is not correct: brw->geometry_program is updated when issuing drawing commands, so after rendering with a GS it will be non-NULL until we draw again with a program that does not have a GS. If the next program uses TF, we will call glBegintransformFeedback before issuing the drawing command and hence brw->geometry_program will be non-NULL if the previous rendering used a GS. The right thing to do here is to check ctx->_Shader->CurrentProgram[MESA_SHADER_GEOMETRY] instead. This is what the gen7 code path does too.
