2018-01-26drm/nouveau: Move irq setup/teardown to pci ctor/dtorLyude Paul1-15/+31
For a while we've been having issues with seemingly random interrupts coming from nvidia cards when resuming them. Originally the fix for this was thought to be just re-arming the MSI interrupt registers right after re-allocating our IRQs, however it seems a lot of what we do is both wrong and not even nessecary. This was made apparent by what appeared to be a regression in the mainline kernel that started introducing suspend/resume issues for nouveau: a0c9259dc4e1 (irq/matrix: Spread interrupts on allocation) After this commit was introduced, we started getting interrupts from the GPU before we actually re-allocated our own IRQ (see references below) and assigned the IRQ handler. Investigating this turned out that the problem was not with the commit, but the fact that nouveau even free/allocates it's irqs before and after suspend/resume. For starters: drivers in the linux kernel haven't had to handle freeing/re-allocating their IRQs during suspend/resume cycles for quite a while now. Nouveau seems to be one of the few drivers left that still does this, despite the fact there's no reason we actually need to since disabling interrupts from the device side should be enough, as the kernel is already smart enough to know to disable host-side interrupts for us before going into suspend. Since we were tearing down our IRQs by hand however, that means there was a short period during resume where interrupts could be received before we re-allocated our IRQ which would lead to us getting an unhandled IRQ. Since we never handle said IRQ and re-arm the interrupt registers, this would cause us to miss all of the interrupts from the GPU and cause our init process to start timing out on anything requiring interrupts. So, since this whole setup/teardown every suspend/resume cycle is useless anyway, move irq setup/teardown into the pci subdev's ctor/dtor functions instead so they're only called at driver load and driver unload. This should fix most of the issues with pending interrupts on resume, along with getting suspend/resume for nouveau to work again. As well, this probably means we can also just remove the msi rearm call inside nvkm_pci_init(). But since our main focus here is to fix suspend/resume before 4.15, we'll save that for a later patch.

2018-01-19drm/nouveau/bar/gk20a: Avoid bar teardown during initJon Hunter2-2/+2
Commit bbb163e18960 ("drm/nouveau/bar: implement bar1 teardown") introduced add a teardown helper function for BAR1. During initialisation of the Nouveau, initially all the teardown helpers are called once, before calling their init counterparts. For gk20a, after the BAR1 teardown function is called, the device is hanging during the initialisation of the FB sub-device. At this point it is unclear why this is happening and this is still under investigation. However, this change is preventing Tegra124 devices from booting when Nouveau is enabled. To allow Tegra124 to boot, remove the teardown helper for gk20a. This is based upon a previous patch by Guillaume Tucker but limits the workaround to only gk20a GPUs.

git://people.freedesktop.org/~thomash/linux into drm-fixes Two important fixes for vmwgfx. The off-by-one fix could cause a malicious user to potentially crash the kernel. The framebuffer map cache fix can under some circumstances enable a user to read from or write to freed pages. * 'vmwgfx-fixes-4.15' of git://people.freedesktop.org/~thomash/linux: drm/vmwgfx: Potential off by one in vmw_view_add() drm/vmwgfx: Don't cache framebuffer maps

git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v4.16-rc1 The bulk of these changes are preparation work and addition of support for Tegra186. Currently only HDMI output (the primary output on Jetson TX2) is supported, but the hardware is also capable of doing DSI and DisplayPort. Tegra DRM now also uses the atomic commit helpers instead of the open- coded variant that was only doing half its job. As a bit of a byproduct of the Tegra186 support the driver also gained HDMI 2.0 as well as zpos property support. Along the way there are also a few patches to clean up a few things and fix minor issues. * tag 'drm/tegra/for-4.16-rc1-fixes' of git://anongit.freedesktop.org/tegra/linux: (51 commits) drm/tegra: dc: Properly cleanup overlay planes drm/tegra: dc: Fix possible_crtcs mask for planes drm/tegra: dc: Restore YUV overlay support drm/tegra: dc: Implement legacy blending drm/tegra: Correct timeout in tegra_syncpt_wait drm/tegra: gem: Correct iommu_map_sg() error checking drm/tegra: dc: Link DC1 to DC0 on Tegra20 drm/tegra: Fix non-debugfs builds drm/tegra: dpaux: Keep reset defaults for hybrid pad parameters drm/tegra: Mark Tegra186 display hub PM functions __maybe_unused drm/tegra: Use IOMMU groups gpu: host1x: Use IOMMU groups drm/tegra: Implement zpos property drm/tegra: dc: Remove redundant spinlock drm/tegra: dc: Use direct offset to plane registers drm/tegra: dc: Support more formats drm/tegra: fb: Force alpha formats drm/tegra: dpaux: Add Tegra186 support drm/tegra: dpaux: Implement runtime PM drm/tegra: sor: Support HDMI 2.0 modes ...

2018-01-11drm/nouveau: deprecate pci_get_bus_and_slot()Sinan Kaya4-6/+21
pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as where a PCI device is present. This restricts the device drivers to be reused for other domain numbers. Getting ready to remove pci_get_bus_and_slot() function in favor of pci_get_domain_bus_and_slot(). Replace pci_get_bus_and_slot() with pci_get_domain_bus_and_slot() and extract the domain number from 1. struct pci_dev 2. struct pci_dev through drm_device->pdev 3. struct pci_dev through fb->subdev->drm_device->pdev Signed-off-by: Sinan Kaya <[email protected]> Signed-off-by: Bjorn Helgaas <[email protected]>

2018-01-11drm/sun4i: hdmi: Add missing rate halving check in sun4i_tmds_determine_rateJonathan Liu1-2/+5
It was only checking the divider when determing the closest match if it could not match the requested rate exactly. For a projector connected to an Olimex A20-OLinuXino-LIME using HDMI with a native resolution of 1280x800 and pixel clock of 83.5 MHz, this resulted in 1280x800 mode not being available and the following in dmesg when the kernel is booted with drm.debug=0x3e: [drm:drm_mode_debug_printmodeline] Modeline 37:"1280x800" 60 83500 1280 1352 1480 1680 800 810 816 831 0x48 0x5 [drm:drm_mode_prune_invalid] Not using 1280x800 mode: NOCLOCK Fixes: 9c5681011a0c ("drm/sun4i: Add HDMI support") Signed-off-by: Jonathan Liu <[email protected]> Signed-off-by: Maxime Ripard <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
