2017-11-02drm/nouveau/core/memory: add reference countingBen Skeggs1-1/+3
We need to be able to prevent memory from being freed while it's still mapped in a GPU's address-space. Will be used by upcoming MMU changes. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/memory: add mechanism to retrieve allocation granularityBen Skeggs1-0/+2
Needed by VMM code to determine whether an allocation is compatible with a given page size (ie. you can't map 4KiB system memory pages into 64KiB GPU pages). Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/memory: change map interface to support upcoming mmu changesBen Skeggs2-9/+8
Map flags (access, kind, etc) are currently defined in either the VMA, or the memory object, which turns out to not be ideal for things like suballocated buffers, etc. These will become per-map flags instead, so we need to support passing these arguments in nvkm_memory_map(). Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/memory: comptag allocationBen Skeggs1-0/+12
nvkm_memory is going to be used by the upcoming mmu rework for the basic representation of a memory allocation, as such, this commit adds support for comptag allocation to nvkm_memory. This is very simple for now, in that it requires comptags for the entire memory allocation even if only certain ranges are compressed. Support for tracking ranges will be added at a later date. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/ltc: init comptag mm in fb subdevBen Skeggs1-1/+0
A single location for the MM allows us to share allocation logic. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/fb/gf100: clear comptags at allocation time rather than mmu mapBen Skeggs1-1/+1
We probably don't want to destroy compression data when doing multiple mappings of a memory object. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/fb: move comptags mm into nvkm_fbBen Skeggs1-1/+1
We're moving towards having a central place to handle comptag allocation, and as some GPUs don't have a ram submodule (ie. Tegra), we need to move the mm somewhere else. It probably never belonged in ram anyways. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/mm: introduce functions to access info about a given allocationBen Skeggs1-0/+30
These will be used in upcoming patches. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/mm: have users explicitly define heap identifiersBen Skeggs2-1/+5
Different sections of VRAM may have different properties (ie. can't be used for compression/display, can't be mapped, etc). We currently already support this, but it's a bit magic. This change makes it more obvious where we're allocating from. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau: separate constant-va tracking from nvkm vma structureBen Skeggs1-2/+0
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau: separate buffer object backing memory from nvkm structuresBen Skeggs2-7/+4
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/mmu/nv04-nv4x: move global vmm to nvkm_mmuBen Skeggs1-0/+2
In a future commit, this will be constructed by common code. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/imem: separate pre-BAR2-bootstrap objects from the restBen Skeggs1-0/+1
These will require slow-path access during suspend/resume. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/memory: split info pointers from accessor pointersBen Skeggs2-4/+11
The accessor functions can change as a result of acquire()/release() calls, and are protected by any refcounting done there. Other functions must remain constant, as they can be called any time. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/bar/gm107-: wait for instance block binding to completeBen Skeggs1-0/+2
Discovered by accident while working to use BAR2 access to instmem objects on more paths. We've apparently been relying on luck up until now! Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/bar: modify interface to bar2 vmm mappingBen Skeggs1-1/+1
Match API with the BAR1 version. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/bar: modify interface to bar1 vmm mappingBen Skeggs2-1/+2
Upcoming changes will remove the nvkm_vmm pointer from nvkm_vma, instead requiring it to be explicitly specified on each operation. It's not currently possible to get this information for BAR1 mappings, so let's fix that ahead of time. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/bar: expose interface to bar2 teardownBen Skeggs1-0/+1
Will prevent spurious MMU fault interrupts if something decides to touch BAR1 after we've unloaded the driver. Exposed external to BAR so that INSTMEM can use it to better control the suspend/resume fast-path access. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/bar: expose interface to bar2 initialisationBen Skeggs1-0/+2
If we want to be able to hit the instmem fast-path in a few trickier cases, we need to be more flexible with when we can initialise BAR2 access. There's probably a decent case to be made for merging BAR/INSTMEM into BUS, but that's something to ponder another day. Flushes have been added after the write to bind the instance block, as later commits will reveal the need for them. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/fifo: perform reset from preinitBen Skeggs1-0/+1
RM appears to do this really early in its initialisation, before DEVINIT. We currently do this before BAR2 initialisation for some reason. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/device: remove object include to prevent unnecessary rebuildsBen Skeggs5-2/+5
nvkm_device hasn't subclassed nvkm_object in a long time. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/subdev: compile out messages for unwanted debug levelsBen Skeggs1-1/+1
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/gpuobj: remove embedded struct nvkm_objectBen Skeggs2-2/+1
nvkm_gpuobj hasn't subclassed nvkm_object in a long time. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/object: plumb the unmap ioctl throughBen Skeggs1-0/+2
MMU will be using this for BAR mappings. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/object: allow arguments to be passed to map functionBen Skeggs3-7/+21
MMU will be needing this to specify kind info on BAR mappings. We have no userspace currently using these interfaces, so break the ABI instead of supporting both. NVIF version bump so any future use can be guarded. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/core/object: separate oclass data out into its own headerBen Skeggs2-27/+32
Want to be able to include this from core/device.h without pulling in core/object.h. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-11-02drm/nouveau/therm/gp100: initial implementation of new gp1xx temperature sensorRhys Kidd1-0/+1
v2: - add nv138 and drop nv13b chipsets (Ilia Mirkin) - refactor out status variable and instead mask tsensor (Ilia Mirkin) - switch SHADOWed state message away from nvkm_error() (Ilia Mirkin) - rename internal temperature variable (Karol Herbst) v3: - use nvkm_trace() for SHADOWed state message (Ben Skeggs) Signed-off-by: Rhys Kidd <rhyskidd@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-08-22drm/nouveau/disp: Silence DCB warnings.Rosen Penev2-0/+2
Most of these errors seem to be WFD related. Official documentation says dcb type 8 is reserved. It's probably used for WFD. Silence the warning in either case. Connector type 70 is stated to be a virtual connector for WiFi display. Since we know this, don't warn that we don't. Signed-off by: Rosen Penev <rosenp@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-08-22drm/nouveau/therm/gm200: AddedKarol Herbst1-0/+1
This allows temperature readouts on maxwell2 GPUs. Signed-off-by: Karol Herbst <karolherbst@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp/nv50-: implement a common supervisor 3.0Ben Skeggs1-5/+1
This makes use of all the additional routing and state added in previous commits, making it possible to deal with GM20x macro link routing, while also sharing code between the NV50 and GF119 implementations. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp: introduce acquire/release display path methodsBen Skeggs1-0/+9
These exist to give NVKM information on the set of display paths that the DD needs to be active at any given time. Previously, the supervisor attempted to determine this solely from OR state, but there's a few configurations where this information on its own isn't enough to determine the specific display paths in question: - ANX9805, where the PIOR protocol for both DP and TMDS is TMDS. - On a device using DCB Switched Outputs. - On GM20x and newer, with a crossbar between the SOR and macro links. After this commit, the DD tells NVKM *exactly* which display path it's attempting a modeset on. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp/nv50-: port OR power state control to nvkm_iorBen Skeggs1-25/+0
Also removes the user-facing methods to these controls, as they're not currently utilised by the DD anyway. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp/dp: remove DP_PWR methodBen Skeggs1-7/+0
This hasn't been used since atomic. We may want to re-implement "fast" DPMS at some point, but for now, this just gets in the way. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp: fork off some new hw-specific implementationsBen Skeggs1-0/+2
Upcoming commits make supervisor handling share code between the NV50 and GF119 implementations. Because of this, and a few other cleanups, we need to allow some additional customisation. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp: introduce input/output resource abstractionBen Skeggs1-0/+1
In order to properly support the SOR -> SOR + pad macro separation that occurred with GM20x GPUs, we need to separate OR handling out of the output path code. This will be used as the base to support ORs (DAC, SOR, PIOR). Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp: introduce object to track per-head functions/stateBen Skeggs1-4/+1
Primarily intended as a way to pass per-head state around during supervisor handling, and share logic between NV50/GF119. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp: delay output path / connector construction until oneinit()Ben Skeggs1-4/+4
This is to allow hw-specific code to instantiate output resources first, so we can cull unsupported output paths based on them. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/bios/init: add a new devinit script interpreter entry-pointBen Skeggs1-0/+13
This will ensure unspecified args are easily identified. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/bios/init: add or/link args separate from output pathBen Skeggs1-0/+2
As of DCB 4.1, these are not the same thing. Compatibility temporarily in place until callers have been updated. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/bios/init: bump script offset to 32-bitsBen Skeggs1-3/+3
No (known) case yet, but other tables have been moving beyond 16-bits, so we may as well be prepared. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/bios/init: rename 'crtc' to 'head'Ben Skeggs1-1/+5
Compatibility temporarily in place until all callers have been updated. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/bios/init: rename nvbios_init() to nvbios_devinit()Ben Skeggs1-1/+1
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/tmr: remove nvkm_timer_alarm_cancel()Ben Skeggs1-1/+0
nvkm_timer_alarm() already handles this as part of protecting against callers passing in no timeout value. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp/g84-: Extend NVKM HDMI power control method to set InfoFramesAlastair Bridgewater1-1/+3
The nouveau driver, in the Linux 3.7 days, used to try and set the AVI InfoFrame based on the selected display mode. These days, it uses a fixed set of InfoFrames. Start to correct that, by providing a mechanism whereby InfoFrame data may be passed to the NVKM functions that do the actual configuration. At this point, only establish the new parameters and their parsing, don't actually use the data anywhere yet (since it's not supplied anywhere). Signed-off-by: Alastair Bridgewater <alastair.bridgewater@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-06drm/nouveau/tmr: fully separate alarm execution/pending listsBen Skeggs1-0/+1
Reusing the list_head for both is a bad idea. Callback execution is done with the lock dropped so that alarms can be rescheduled from the callback, which means that with some unfortunate timing, lists can get corrupted. The execution list should not require its own locking, the single function that uses it can only be called from a single context.

2017-04-06drm/nouveau/gr/gp107: initial supportBen Skeggs1-0/+1
Forked from GP106 implementation. Differences: - 1 PPC/GPC - Slightly different grctx magics Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-04-06drm/nouveau/platform: make VDD regulator optionalAlexandre Courbot1-0/+4
GP10B's power is managed by generic PM domains, so it does not require a VDD regulator. Add this option into the chip function structure. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-04-06drm/nouveau/gr: support for GP10BAlexandre Courbot1-0/+1
GR is similar to GP100, with a few unavailable registers. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-04-06drm/nouveau/ibus: add GP10B supportAlexandre Courbot1-0/+1
GP10B requires a specific initialization sequence due to the absence of devinit. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-04-06drm/nouveau/mc: add GP10B supportAlexandre Courbot1-0/+1
GP10B's MC is compatible with GP100's, but engines need to be explicitly put out of ELPG during init. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
