* iris/bufmgr: Factor out GEM_MMAP ioctl from mmap_cpu and mmap_wc.Rafael Antognolli2020-04-201-30/+31
| | | | | | | | | | | | | | | We want to add a new ioctl for mmap'ing buffers, so let's avoid duplicating that code on both functions by extracting it from them first.

| | | | | | | | | | | | | | | tc_transfer_map maps buffers directly, but the unmap operation is executed in the driver thread. When an application does a lot of map/unmap operations, without flushing, this increase the RAM used (and eventually get the app killed by the oom-killer). This commit allows tc to keep track of how many bytes were mapped during the current batch. When this estimation becomes higher than a threshold, we flush the batch.

| | | | | | | | | | | | | Iris allocates gem buffers using buckets of allocation sizes that are page aligned. We always ask for batch buffers of size BATCH_SZ + BATCH_RESERVED, which is not page aligned: we ask for 65552 bytes, which ends up in the bucket of size 81920, resulting in 20% unused space.

For a full Aztec run on BDW we allocate this struct 3273 times, and we can have up to 3259 of them live at the same time. So we end up saving just a little over 6 pages for this benchmark.

* freedreno/turnip: Update GRAS_LAYER_CNTL to GRAS_MAX_LAYER_INDEXBrian Ho2020-04-151-15/+3
| | | | | | | | | | | | | | | | | | | | | | | | After some experimentation, I believe that GRAS_LAYER_CNTL is actually just a count register storing the number of layers in the render target. While debugging cube_array geometry tests, I noticed that the blob was setting an unknown 0x8 to LAYER_CNTL, so I checked the value of LAYER_CNTL for various layer sizes: 1: LAYER_CNTL=0 2: LAYER_CNTL=1 3: LAYER_CNTL=2 4: LAYER_CNTL=3 9: LAYER_CNTL=8 256: LAYER_CNTL=255 2000: LAYER_CNTL=1999 Seems like this register just stores a count of the largest layer that can be written to via gl_Layer.
