| * | | drm/nouveau/mc: expose device enable/disable separately, as well as resetBen Skeggs2016-07-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are cases where subdevs need to perform additonal actions around the master reset, so we want to expost the operations separately. This commit also adds a flag to the NV_PMC_ENABLE bitfield definitions which allow skipping the automatic reset() called from core/subdev.c. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

There is apparently something amiss with the way the TTM code handles DMA buffers, which the above commit was attempting to work around for arm64 systems with non-coherent PCI. Unfortunately, this completely breaks systems *with* coherent PCI (which appear to be the majority). Booting a plain arm64 defconfig + CONFIG_DRM + CONFIG_DRM_NOUVEAU on a machine with a PCI GPU having coherent dma_map_ops (in this case a 7600GT card plugged into an ARM Juno board) results in a fatal crash: [ 2.803438] nouveau 0000:06:00.0: DRM: allocated 1024x768 fb: 0x9000, bo ffffffc976141c00 [ 2.897662] Unable to handle kernel NULL pointer dereference at virtual address 000001ac [ 2.897666] pgd = ffffff8008e00000 [ 2.897675] [000001ac] *pgd=00000009ffffe003, *pud=00000009ffffe003, *pmd=0000000000000000 [ 2.897680] Internal error: Oops: 96000045 [#1] PREEMPT SMP [ 2.897685] Modules linked in: [ 2.897692] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.6.0-rc5+ #543 [ 2.897694] Hardware name: ARM Juno development board (r1) (DT) [ 2.897699] task: ffffffc9768a0000 ti: ffffffc9768a8000 task.ti: ffffffc9768a8000 [ 2.897711] PC is at __memcpy+0x7c/0x180 [ 2.897719] LR is at OUT_RINGp+0x34/0x70 [ 2.897724] pc : [<ffffff80083465fc>] lr : [<ffffff800854248c>] pstate: 80000045 [ 2.897726] sp : ffffffc9768ab360 [ 2.897732] x29: ffffffc9768ab360 x28: 0000000000000001 [ 2.897738] x27: ffffffc97624c000 x26: 0000000000000000 [ 2.897744] x25: 0000000000000080 x24: 0000000000006c00 [ 2.897749] x23: 0000000000000005 x22: ffffffc97624c010 [ 2.897755] x21: 0000000000000004 x20: 0000000000000004 [ 2.897761] x19: ffffffc9763da000 x18: ffffffc976b2491c [ 2.897766] x17: 0000000000000007 x16: 0000000000000006 [ 2.897771] x15: 0000000000000001 x14: 0000000000000001 [ 2.897777] x13: 0000000000e31b70 x12: ffffffc9768a0080 [ 2.897783] x11: 0000000000000000 x10: fffffffffffffb00 [ 2.897788] x9 : 0000000000000000 x8 : 0000000000000000 [ 2.897793] x7 : 0000000000000000 x6 : 00000000000001ac [ 2.897799] x5 : 00000000ffffffff x4 : 0000000000000000 [ 2.897804] x3 : 0000000000000010 x2 : 0000000000000010 [ 2.897810] x1 : ffffffc97624c010 x0 : 00000000000001ac ...

Which means we only need to have a special set_busid for pci devices, to be able to care the backwards compat code for drm 1.1 around, which libdrm still needs. While developing and testing this patch things blew up in really interesting ways, and the code is rather confusing in naming things between the kernel code, ioctl #defines and libdrm. For the next brave dragon slayer, document all this madness properly in the userspace interface section of gpu.tmpl. v2: Make drm_dev_set_unique static and update kerneldoc. v3: Entire rewrite, plus document what's going on for posterity in the gpu docbook uapi section. v4: Drop accidental amdgpu hunk (Emil). v5: Drop accidental omapdrm vblank counter change (Emil). v6: Rebase on top of the sphinx conversion.

| * | drm/fence: add fence to drm_pending_eventGustavo Padovan2016-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now a drm_pending_event can either send a real drm_event or signal a fence, or both. It allow us to signal via fences when the buffer is displayed on the screen. Which in turn means that the previous buffer is not in use anymore and can be freed or sent back to another driver for processing. v2: Comments from Daniel Vetter - call fence_signal in drm_send_event_locked() - remove unneeded !e->event check v3: Remove drm_pending_event->destroy to fix a leak when e->file_priv is not set.

| * | dma-buf/fence: make fence context 64 bit v2Christian König2016-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fence contexts are created on the fly (for example) by the GPU scheduler used in the amdgpu driver as a result of an userspace request. Because of this userspace could in theory force a wrap around of the 32bit context number if it doesn't behave well. Avoid this by increasing the context number to 64bits. This way even when userspace manages to allocate a billion contexts per second it takes more than 500 years for the context number to wrap around. v2: fix printf formats as well.

* / vga_switcheroo: Add helper for deferred probingLukas Wunner2016-05-31
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far we've got one condition when DRM drivers need to defer probing on a dual GPU system and it's coded separately into each of the relevant drivers. As suggested by Daniel Vetter, deduplicate that code in the drivers and move it to a new vga_switcheroo helper. This yields better encapsulation of concepts and lets us add further checks in a central place. (The existing check pertains to pre-retina MacBook Pros and an additional check is expected to be needed for retinas.) One might be tempted to check deferred probing conditions in vga_switcheroo_register_client(), but this is usually called fairly late during driver load. The GPU is fully brought up and ready for switching at that point. On boot the ->probe hook is potentially called dozens of times until it finally succeeds, and each time we'd repeat bringup and teardown of the GPU, lengthening boot time considerably and cluttering logfiles. A separate helper is therefore needed which can be called right at the beginning of the ->probe hook. Note that amdgpu currently does not call this helper as the AMD GPUs built into MacBook Pros are only supported by radeon so far. v2: This helper could eventually be used by audio clients as well, so rephrase kerneldoc to refer to "client" instead of "GPU" and move the single existing check in an if block specific to PCI_CLASS_DISPLAY_VGA devices. Move documentation on that check from kerneldoc to a comment. (Daniel Vetter) v3: Mandate in kerneldoc that registration of client shall only happen after calling this helper. (Daniel Vetter) v4: Rebase on 412c8f7de011 ("drm/radeon: Return -EPROBE_DEFER when amdkfd not loaded") v5: Some Optimus GPUs use PCI_CLASS_DISPLAY_3D, make sure those are matched as well. (Emil Velikov) v6: The if-condition referring to PCI_BASE_CLASS_DISPLAY may be considered a functional change. Move to a separate commit to keep this a pure refactoring change.
