* | gpu: nvgpu: improve channel interleave supportAingara Paramakuru2016-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, only "high" priority bare channels were interleaved between all other bare channels and TSGs. This patch decouples priority from interleaving and introduces 3 levels for interleaving a bare channel or TSG: high, medium, and low. The levels define the number of times a channel or TSG will appear on a runlist (see nvgpu.h for details). By default, all bare channels and TSGs are set to interleave level low. Userspace can then request the interleave level to be increased via the CHANNEL_SET_RUNLIST_INTERLEAVE ioctl (TSG-specific ioctl will be added later). As timeslice settings will soon be coming from userspace, the default timeslice for "high" priority channels has been restored.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Restore comptags to be bitmap-allocated, like they were before we had the buddy allocator. The new buddy allocator introduced by e99aa2485f8992eabe3556f3ebcb57bdc8ad91ff (originally 6ab2e0c49cb79ca68d2f83f1d4610783d2eaa79b) is fine for the big VAs, but unsuitable for the small compbit store. This commit reverts partially the combination of the above commit and also one after it, 86fc7ec9a05999bea8de320840b962db3ee11410, that fixed a bug which is not present when using a bitmap. With a bitmap allocator, pruning the extra allocation necessary for user-mapped mode is possible, so that is also restored. The original generic bitmap allocator is not restored; instead, a comptag-only allocator is introduced.

* gpu: nvgpu: add high priority channel interleavePeter Pipkorn2016-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Interleave all high priority channels between all other channels. This reduces the latency for high priority work when there are a lot of lower priority work present, imposing an upper bound on the latency. Change the default high priority timeslice from 5.2ms to 3.0 in the process, to prevent long running high priority apps from hogging the GPU too much. Introduce a new debugfs node to enable/disable high priority channel interleaving. It is currently enabled by default. Adds new runlist length max register, used for allocating suitable sized runlist. Limit the number of interleaved channels to 32. This change reduces the maximum time a lower priority job is running (one timeslice) before we check that high priority jobs are running. Tested with gles2_context_priority (still passes) Basic sanity testing is done with graphics_submit (one app is high priority) Also more functional testing using lots of parallel runs with: NVRM_GPU_CHANNEL_PRIORITY=3 ./gles2_expensive_draw –drawsperframe 20000 –triangles 50 –runtime 30 –finish plus multiple: NVRM_GPU_CHANNEL_PRIORITY=2 ./gles2_expensive_draw –drawsperframe 20000 –triangles 50 –runtime 30 -finish Previous to this change, the relative performance between high priority work and normal priority work comes down to timeslice value. This means that when there are many low priority channels, the high priority work will still drop quite a lot. But with this change, the high priority work will roughly get about half the entire GPU time, meaning that after the initial lower performance, it is less likely to get lower in performance due to more apps running on the system. This change makes a large step towards real priority levels. It is not perfect and there are no guarantees on anything, but it is a step forwards without any additional CPU overhead or other complications. It will also serve as a baseline to judge other algorithms against. Support for priorities with TSG is future work. Support for interleave mid + high priority channels, instead of just high, is also future work.

Bit 16 of GPU VA is used for determining which half of comptagline is used. This creates problems if user space wants to map a page multiple times and to arbitrary GPU VA. In one mapping the page might be mapped to lower half of 128k comptagline, and in another mapping the page might be mapped to upper half. Turn on mode where MSB of comptagline in PTE is used instead of bit 16 for determining the comptagline lower/upper half selection.
