2020-08-31drm/nouveau/kms: Only use hpd_work for reprobing in HPD pathsLyude Paul
Currently we perform both short IRQ handling for DP, and connector reprobing in the HPD IRQ handler. However since we need to grab connection_mutex in order to reprobe a connector, in theory we could accidentally block ourselves from handling any short IRQs until after a modeset completes if a connector hotplug happens to occur in parallel with a modeset. I haven't seen this actually happen yet, but since we're cleaning up nouveau's hotplug handling code anyway and we already have a hpd worker, we can simply fix this by only relying on the HPD worker to actually reprobe connectors when we receive a HPD IRQ. We also add a mask to nouveau_drm to keep track of which connectors are waiting to be reprobed in response to an HPD IRQ.

2020-04-07drm/nouveau: workaround runpm fail by disabling PCI power management on ↵Karol Herbst
certain intel bridges Fixes the infamous 'runtime PM' bug many users are facing on Laptops with Nvidia Pascal GPUs by skipping said PCI power state changes on the GPU. Depending on the used kernel there might be messages like those in demsg: "nouveau 0000:01:00.0: Refused to change power state, currently in D3" "nouveau 0000:01:00.0: can't change power state from D3cold to D0 (config space inaccessible)" followed by backtraces of kernel crashes or timeouts within nouveau. It's still unkown why this issue exists, but this is a reliable workaround and solves a very annoying issue for user having to choose between a crashing kernel or higher power consumption of their Laptops.

2019-08-20hmm: use mmu_notifier_get/put for 'struct hmm'Jason Gunthorpe
This is a significant simplification, it eliminates all the remaining 'hmm' stuff in mm_struct, eliminates krefing along the critical notifier paths, and takes away all the ugly locking and abuse of page_table_lock. mmu_notifier_get() provides the single struct hmm per struct mm which eliminates mm->hmm. It also directly guarantees that no mmu_notifier op callback is callable while concurrent free is possible, this eliminates all the krefs inside the mmu_notifier callbacks. The remaining krefs in the range code were overly cautious, drivers are already not permitted to free the mirror while a range exists.

2019-07-31drm/nouveau: Fill out gem_object->resvDaniel Vetter
That way we can ditch our gem_prime_res_obj implementation. Since ttm absolutely needs the right reservation object all the boilerplate is already there and we just have to wire it up correctly. Note that gem/prime doesn't care when we do this, as long as we do it before the bo is registered and someone can call the handle2fd ioctl on it. Aside: ttm_buffer_object.ttm_resv could probably be ditched in favour of always passing a non-NULL resv to ttm_bo_init(). At least for gem drivers that would avoid having two of these, on in ttm_buffer_object and the other in drm_gem_object, one just there for confusion.

2019-02-20drm/nouveau/svm: initial support for shared virtual memoryBen Skeggs
This uses HMM to mirror a process' CPU page tables into a channel's page tables, and keep them synchronised so that both the CPU and GPU are able to access the same memory at the same virtual address. While this code also supports Volta/Turing, it's only enabled for Pascal GPUs currently due to channel recovery being unreliable right now on the later GPUs.

2019-02-20drm/nouveau: prepare for enabling svm with existing userspace interfacesBen Skeggs
For a channel to make use of SVM features, it requires a different GPU MMU configuration than we would normally use, which is not desirable to switch to unless a client is actively going to use SVM. In order to supporting SVM without more extensive changes to the userspace interfaces, the SVM_INIT ioctl needs to replace the previous configuration safely. The only way we can currently do this safely, accounting for some unlikely failure conditions, is to allocate the new VMM without destroying the last one, and prioritising the SVM-enabled configuration in the code that cares. This will get cleaned up again further down the track. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2018-12-11drm/nouveau/drm/nouveau: tegra: Call nouveau_drm_device_init()Thierry Reding
As part of commit cfea88a4d866 ("drm/nouveau: Start using new drm_dev initialization helpers"), the initialization of the Nouveau DRM device was reworked and along the way the platform driver initialization was left incomplete. Add a call to nouveau_drm_device_init() to make sure all of the structures are properly initialized.

2018-10-11drm/nouveau: Start using new drm_dev initialization helpersLyude Paul
Per the documentation in drm_get_pci_dev(), this function is deprecated and shouldn't be used anymore. As it turns out, we're going to need to stop using drm_get_pci_dev() anyway in order to allow us to turn off the card before full system shutdowns, otherwise we'll hit race conditions with userspace while trying to tear down the card on shutdown. So, start using drm_dev_get() and drm_dev_put(), and just turn our load/unload callbacks into open coded init/fini() functions.

2018-10-11drm/nouveau: Fix potential memory leak in nouveau_drm_load()Lyude Paul
We forget to free drm in all instances of failure, and additionally also forget to destroy the master client if the other client fails initialization. Signed-off-by: Lyude Paul <lyude@redhat.com> Cc: Karol Herbst <kherbst@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-09-07drm/nouveau: fix oops in client init failure pathBen Skeggs
The NV_ERROR macro requires drm->client to be initialised, which it may not be at this stage of the init process. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-09-07drm/nouveau/drm/nouveau: Don't forget to cancel hpd_work on suspend/unloadLyude Paul
Currently, there's nothing in nouveau that actually cancels this work struct. So, cancel it on suspend/unload. Otherwise, if we're unlucky enough hpd_work might try to keep running up until the system is suspended.

2018-09-07drm/nouveau: Remove useless poll_enable() call in drm_load()Lyude Paul
Again, this doesn't do anything. drm_kms_helper_poll_enable() will have already been called in nouveau_display_init() Signed-off-by: Lyude Paul <lyude@redhat.com> Reviewed-by: Karol Herbst <kherbst@redhat.com> Acked-by: Daniel Vetter <daniel@ffwll.ch> Cc: Lukas Wunner <lukas@wunner.de> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-09-07drm/nouveau: Remove duplicate poll_enable() in pmops_runtime_suspend()Lyude Paul
Since actual hotplug notifications don't get disabled until nouveau_display_fini() is called, all this will do is cause any hotplugs that happen between this drm_kms_helper_poll_disable() call and the actual hotplug disablement to potentially be dropped if ACPI isn't around to help us.
