* r300g: only set clip_halfz for chips with HW TCLMarek Olšák2014-10-281-1/+1
| | | | | I forgot that we cannot emit vertex shader state on a chip without VS. In such a case, clip_halfz is handled by the Draw module.

* gallium/util: use ui[4] instead of ui in union util_colorRoland Scheidegger2014-04-251-1/+1
| | | | | | | | util_color often merely represents a collection of bytes, however it is inconvenient if those bytes can only be accessed as floats/doubles for int formats exceeding 32bits. (Note that since rgba8 formats use one uint, not 4 bytes, hence the byte and short member were left as is.)

* winsys/radeon: set/get the scanout flag with the tiling ioctlsMarek Olšák2013-12-121-1/+1
| | | | | | | | | | | | | | | If we assume that all buffers allocated by the DDX are scanout, a new flag that says "this is not scanout" has to be added to support the non-scanout buffers and maintain backward compatibility. This fixes bad rendering on Wayland. The flag is defined as: #define RADEON_TILING_R600_NO_SCANOUT RADEON_TILING_SWAP_16BIT AFAIK, RADEON_TILING_SWAP_16BIT is not used on SI.

* gallium: new, unified pipe_context::set_sampler_views() functionBrian Paul2013-10-231-4/+9
| | | | | | | | | | | | The new function replaces four old functions: set_fragment/vertex/ geometry/compute_sampler_views(). Note: at this time, it's expected that the 'start' parameter will always be zero.

* draw: try to prevent overflows on index buffersZack Rusin2013-05-141-1/+1
| | | | | | | | | | | | Pass in the size of the index buffer, when available, and use it to handle out of bounds conditions. The behavior in the case of an overflow needs to be the same as with other overflows in the vertex processing pipeline meaning that a vertex should still be generated but all attributes in it set to zero.

* draw: don't crash on vertex buffer overflowZack Rusin2013-05-141-2/+2
| | | | | | | | | | | | | | We would crash when stride was bigger than the size of the buffer. The correct behavior is to just fetch zero's in this case. Unfortunatly with user_buffer's there's no way to validate the size because currently we're just not getting it. Adjust the draw interface to pass the size along the mapped buffer, which works perfectly for buffer backed vertex_buffers and, in future, it will allow us to plumb user_buffer sizes through the same interface.

* r300g: implement MSAA compression and fast MSAA color clearMarek Olšák2013-01-151-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | These are optimizations which make MSAA a lot faster. The MSAA work is complete with this commit. (except for enablement of AA optimizations for RGBA16F, for which a patch is ready and waiting until the kernel CS checker fix lands) MSAA can't be made any faster as far as hw programming is concerned. The catch is only one process and one colorbuffer can use the optimizations at a time. There usually is only one MSAA colorbuffer, so it shouldn't be an issue. Also, there is a limit on the size of MSAA colorbuffer resolution in terms of megapixels. If the limit is surpassed, the AA optimizations are disabled. The limit is: - 1 Mpix on low-end and some mid-level chipsets (1024x768 and 1280x720) - 2 Mpix on some mid-level chipsets (1600x1200 and 1920x1080) - 3 or 4 Mpix on high-end chipsets (2048x1536 or 2560x1600, respectively) It corresponds to the number of raster pipes (= GB pipes) available, each pipe can hold 1 Mpix of AA compression data. If it's enabled, the driver prints to stdout: radeon: Acquired access to AA optimizations.
* r300g: don't set sample positions to the pixel center if MSAA is disabledMarek Olšák2013-01-101-2/+0
| | | | | | | | | | | but an MSAA resource is bound. This effectively makes the MSAA disable switch not affect rasterization, but it still affects the alpha-to-one and alpha-to-coverage states. This hardware just lacks a proper MSAA disable switch. This fixes graphics corruption in sauerbraten. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=59194
* r300g: implement MSAAMarek Olšák2013-01-061-17/+74
| | | | | | | | | | | | | | | | | | | | | | This is not as optimized as r600g - the MSAA compression is missing, so r300g needs a lot of bandwidth (more than r600g to do the same thing). However, if the bandwidth is not an issue for you, you can enjoy this unoptimized MSAA support. The only other missing optimization for MSAA is the fast color clear. MSAA is enabled on r500 only, because that's the only GPU family I tested. That said, MSAA should work on r300 and r400 as well (but you must set RADEON_MSAA=1 to allow it, then turn MSAA on in your app or set GALLIUM_MSAA=n, n >= 2, n <= 6) I will enable the support by default on r300-r400 once someone (other than me) tests those chipsets with piglit. The supported modes are 2x, 4x, 6x. The supported MSAA formats are RGBA8, BGRA8, and RGBA16F (r500 only). Those 3 formats are used for all GL internal formats. Tested with piglit. (I have ported all MSAA tests to GL2.1)

* gallium: add start_slot parameter to set_vertex_buffersMarek Olšák2012-10-311-11/+12
| | | | | | | | | | | | | | | | | | | | | This allows updating only a subrange of buffer bindings. set_vertex_buffers(pipe, start_slot, count, NULL) unbinds buffers in that range. Binding NULL resources unbinds buffers too (both buffer and user_buffer must be NULL). The meta ops are adapted to only save, change, and restore the single slot they use. The cso_context can save and restore only one vertex buffer slot. The clients can query which one it is using cso_get_aux_vertex_buffer_slot. It's currently set to 0. (the Draw module breaks if it's set to non-zero) It should decrease the CPU overhead when using a lot of meta ops, but the drivers must be able to treat each vertex buffer slot as a separate state (only r600g does so at the moment). I can imagine this also being useful for optimizing some OpenGL use cases. Reviewed-by: Brian Paul <[email protected]>
