2021-08-18drm/nouveau: block a bunch of classes from userspaceBen Skeggs1-0/+1
Long ago, there had been plans for making use of a bunch of these APIs from userspace and there's various checks in place to stop misbehaving. Countless other projects have occurred in the meantime, and the pieces didn't finish falling into place for that to happen. They will (hopefully) in the not-too-distant future, but it won't look quite as insane. The super checks are causing problems right now, and are going to be removed.

Moving the driver-specific mmap code into a GEM object function allows for using DRM helpers for various mmap callbacks. The GEM object function is provided by GEM TTM helpers. Nouveau's implementation of verify_access is unused and has been removed. Access permissions are validated by the DRM helpers.

2020-08-31drm/nouveau/kms: Only use hpd_work for reprobing in HPD pathsLyude Paul1-2/+2
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 Herbst1-0/+63
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 Gunthorpe1-0/+3
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 Vetter1-1/+0
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.

2019-05-01drm/nouveau/nouveau: forward error generated while resuming objects treeTobias Klausmann1-1/+11
On a failed resume we may experience unrecoverable errors. Plumb the error code through to actually let the driver fail. On a reverse-prime setup this helps the drm subsystem to at least recover the integrated gpu. This can especially happen with secboot timing out, leaving the hardware in a non-functioning state.

2019-04-24drm/nouveau: add kconfig option to turn off nouveau legacy contexts. (v3)Dave Airlie1-2/+5
There was a nouveau DDX that relied on legacy context ioctls to work, but we fixed it years ago, give distros that have a modern DDX the option to break the uAPI and close the mess of holes that legacy context support is. Full context of the story: commit 0e975980d435d58df2d430d688b8c18778b42218 Author: Peter Antoine <peter.antoine@intel.com> Date: Tue Jun 23 08:18:49 2015 +0100 drm: Turn off Legacy Context Functions The context functions are not used by the i915 driver and should not be used by modeset drivers. These driver functions contain several bugs and security holes. This change makes these functions optional can be turned on by a setting, they are turned off by default for modeset driver with the exception of the nouvea driver that may require them with an old version of libdrm. The previous attempt was commit 7c510133d93dd6f15ca040733ba7b2891ed61fd1 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Aug 8 15:41:21 2013 +0200 drm: mark context support as a legacy subsystem but this had to be reverted commit c21eb21cb50d58e7cbdcb8b9e7ff68b85cfa5095 Author: Dave Airlie <airlied@redhat.com> Date: Fri Sep 20 08:32:59 2013 +1000 Revert "drm: mark context support as a legacy subsystem" v2: remove returns from void function, and formatting (Daniel Vetter) v3: - s/Nova/nouveau/ in the commit message, and add references to the previous attempts - drop the part touching the drm hw lock, that should be a separate patch.

2019-02-20drm/nouveau/svm: new ioctl to migrate process memory to GPU memoryJérôme Glisse1-0/+1
This add an ioctl to migrate a range of process address space to the device memory. On platform without cache coherent bus (x86, ARM, ...) this means that CPU can not access that range directly, instead CPU will fault which will migrate the memory back to system memory. This is behind a staging flag so that we can evolve the API. Signed-off-by: Jérôme Glisse <jglisse@redhat.com>
2019-02-20drm/nouveau/dmem: device memory helpers for SVMJérôme Glisse1-0/+5
Device memory can be use in SVM, in which case we do not have any of the existing buffer object. This commit add infrastructure to allow use of device memory without nouveau_bo. Again this is a temporary solution until a rework of GPU memory management. Signed-off-by: Jérôme Glisse <jglisse@redhat.com>
2019-02-20drm/nouveau/svm: initial support for shared virtual memoryBen Skeggs1-1/+6
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 Skeggs1-0/+1
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>
2019-02-20drm/nouveau: allow accelerated buffer moves even when gr isn't presentBen Skeggs1-85/+128
There's no need to avoid using copy engines if gr init fails for some reason (usually missing FW, or incomplete bring-up). It's not terribly useful for an end-user, but it'll slightly speed up suspend/resume when saving fb contents, and allow for host/ce code to be validated.

2019-02-20drm/nouveau: allocate kernel channel(s) before initialising displayBen Skeggs1-2/+4
Some of the pre-NV50 depends on SW methods to implement synchronisation for page flips, and we want to move this setup out of common code, thus we require the channel to have been allocation before display init. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
