2016-03-14drm/nouveau/clk/gk20a: emit parent rate as debug messageAlexandre Courbot
Most users are probably not interested in this information. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/clk/gk20a: only restore divider to 1:1 if neededAlexandre Courbot
Only restore the 1:1 divider if it is not set already. Also use the proper masks for this operation and add a second write as done in the Android code. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/clk/gk20a: only compute n_lo if neededAlexandre Courbot
n_lo is used if we are going to slide. Compute it only if that condition succeeds to avoid confusion about future usage of this computation. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/clk/gk20a: fix VCO bit maskAlexandre Courbot
Fix the mask specified to switch to VCO mode was given as an (incorrect) immediate value. Although the side-effect happens to be the same, this is clearly incorrect. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/clk/gk20a: rename enable/disable functionsAlexandre Courbot
gk20a_pllg_disable() is only used in the context of gk20a_clk_fini(). Move its body there and rename _gk20a_pllg_enable() and _gk20a_pllg_disable() to non-underscored versions. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/clk/gk20a: reorganize variables in gk20a_pllg_calc_mnp()Alexandre Courbot
Move some variables declarations to the scope where they are actually used to make the code easier to follow. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/clk/gk20a: convert parameters to KhzAlexandre Courbot

2016-03-14drm/nouveau/volt/gk20a: split constructorAlexandre Courbot
Split the constructor function so we can reuse the same logic in other chips. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/volt/gk20a: share reusable members & functionsVince Hsu
The CVB calculation and voltage setting functions can be reused for the future chips. So move the declaration to gk20a.h. Signed-off-by: Vince Hsu <vinceh@nvidia.com> Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/ce/gm107: expose MaxwellDmaCopyABen Skeggs

2016-03-14drm/nouveau/fifo/gm107: KeplerChannelGpfifoB, and 2048 channelsBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/fifo/gk110: expose KeplerChannelGpfifoBBen Skeggs
This class supports a WFI method (0x0078) that's not present on the KeplerChannelGpfifoA class. The binary driver exposes both classes on these GPUs for some reason, though there doesn't appear to be any difference in the setup that's done for each (ie. even if you allocate GpfifoA, the WFI method will still work). We shall just expose GpfifoB, as I don't see a good reason to report the presence of both. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-03-14drm/nouveau/gr/fuc: Store $r0 in interrupt handlerRoy Spliet
It's supposed to always be 0, but at least nv_iowr() temporarily violates this. Since the ih touches $r0, it should be stored. Signed-off-by: Roy Spliet <rs855@cam.ac.uk> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-03-14drm/nouveau/core: use vzalloc for allocating ramhtIlia Mirkin
Most calls to nvkm_ramht_new use 0x8000 as the size. This results in a fairly sizeable chunk of memory to be allocated, which may not be available with kzalloc. Since this is done fairly rarely (once per channel), use vzalloc instead. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/fifo/gk104: kick channel upon removalAlexandre Courbot
A channel may still be processed by the PBDMA even after removal, unless it is properly kicked. Some chips are more sensible to this than others, with GM20B triggering the issue very easily (the PBDMA will try to fetch methods from the previously-removed channel after a new one is added). Make sure this cannot happen by kicking the channel right after it is disabled, and before the new runlist is submitted.

2016-03-14drm/nouveau/instmem/gk20a: add write barrier when releasing DMA objectAlexandre Courbot
When using the DMA-API for instmem, we may obtain a write-combined mapping. For such cases, add a write barrier in gk20a_instobj_release_dma() to make sure that all writes have reached memory at this time.

2016-03-14drm/nouveau/device/pci: set as non-CPU-coherent on ARM64Alexandre Courbot
Without this buffer inconsistencies may appear between the CPU and GPU when using a PCI GPU on an ARM64 board. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/hwmon: fix crash on non-PCI platformsAlexandre Courbot
Registration of the hwmon device will fail on non-PCI systems since dev->pdev is NULL in that case. Use the more generic drm_device::dev member that points to the same and is always set no matter the platform.

2016-03-14drm/nouveau/bo: consider DMA buffers on x86 onlyAlexandre Courbot
The DMA API has different semantics on different architectures. Currently on arm64, it can only provide memory from a small pool which dries up quickly if we attempt to allocate big buffers from it. Do not consider that option when running on non-x86, since regular TTM buffers are the (current) best-fit for ARM platforms.

2016-03-14drm/nouveau/ltc/gf100: use more reasonable timeout valueAlexandre Courbot
LTC operations timeout was set to 2ms, which may be too low for devices that run at very low clocks (e.g. GM20B) and trigger timeout messages. Set the timeout to the default 2s. Also remove the redundant error messages since nvkm_wait_msec() will already display a warning. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-03-14drm/nouveau/fifo/gk104: take runlist target into accountAlexandre Courbot
Bits 28:29 of RUNLIST_BASE specify the memory target of the runlist. Set it to 0x3 (SYS_MEM_NONCOHERENT) if the runlist object resides in system memory. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
