2016-07-14drm/nouveau: prevent oops if no mmu subdev presentBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-14drm/nouveau/disp/g94: implement workaround for dvi issue on fx380Ben Skeggs
Fixes the second DVI output on Quadro FX380. Thanks to NVIDIA for providing the details on the full workaround. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-14drm/nouveau/bios: pointers beyond end of first image need special handlingBen Skeggs
Makes common the code that was previously used by the PMU table parsing, as it appears other tables need this too. Not much of an idea what this is all about... Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-14drm/nouveau/bios: guard against out-of-bounds accesses to imageBen Skeggs

2016-07-14drm/nouveau/disp/nv50-: fix lookup of udisp table under certain circumstancesBen Skeggs
Some VBIOS have separate tables for each link of a given output path, which means we have to specify the specific link we're using instead of all possible links. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-14drm/nouveau/ltc/gm107-: decode interrupt status to human-readable stringsBen Skeggs

2016-07-14drm/nouveau/clk/gf100-: Clean up PLL locking testRoy Spliet
Corresponds with GT215. Don't rely on the lock test logic being unconditionally enabled, and disable test logic when done (presumably to save power). v2: Remove warning, nvkm_msec already warns on time-out Signed-off-by: Roy Spliet <nouveau@spliet.org> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-14drm/nouveau/secboot: lazy-load firmware and be more resilientAlexandre Courbot
Defer the loading of firmware files to the chip-specific part of secure boot. This allows implementations to retry loading firmware if the first attempt failed ; for the GM200 implementation, this happens when trying to reset a falcon, typically in reaction to GR init. Firmware loading may fail for a variety of reasons, such as the filesystem where they reside not being ready at init time. This new behavior allows GR to be initialized the next time we try to use it if the firmware has become available.

2016-07-14drm/nouveau/secboot/gm200: make firmware loading re-callableAlexandre Courbot
Make it possible to call gm20x_secboot_prepare_blobs() several times after either success or failure without re-building already existing blobs. The function will now try to load firmware files that have previously failed before returning success. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-14drm/nouveau/gr/gf100: handle secure boot errorsAlexandre Courbot
Handle and propagate secure boot errors. Failure to do so results in Nouveau incorrectly believing init has succeeded and a completely black display during boot. If we propagate the error, GR init will fail and the user will at least have a working display. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-14drm/nouveau/secboot: fix kerneldoc for secure boot structuresAlexandre Courbot

2016-07-14drm/nouveau/volt: save the voltage range we are able to setKarol Herbst
We shouldn't set voltages below the min or above the max voltage the gpu is able to set, so save the range for future lookups. Signed-off-by: Karol Herbst <karolherbst@gmail.de> Reviewed-by: Martin Peres <martin.peres@free.fr> Tested-by: Pierre Moreau <pierre.morrow@free.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-14drm/nouveau/clk/gm20b: add glitchless and DFS supportAlexandre Courbot
This patch adds support for advanced features supported by the Noise-Aware PLL of Maxwell. Glitchless switch allows the PL field to be updated without disabling the PLL first if the SYNC_MODE bit of the CFG register is set. More significantly, DFS allows the PLL to monitor the actual input voltage and to dynamically lower the output frequency accordingly. This allows the clock to be more tolerant of lower voltages. These improvements are only supported for Tegra speedos >= 1. Also add the voltage table that is suitable for GM20B's NAPLL. This change needs to be done atomically for the right voltages to be used by the clock driver. v2. Fix build on non-Tegra platforms Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-14drm/nouveau/clk/gk20a: rename constructorAlexandre Courbot

2016-07-14drm/nouveau/clk/gk20a: improve MNP programmingAlexandre Courbot
Split the MNP programming function into two functions for the cases where we allow sliding or not, instead of making it take a parameter for this. This results in less conditionals in the code and makes it easier to read. Also make the MNP programming functions take the PLL parameters as arguments, and move bits of code to more relevant places (previous programming tended to be just-in-time, which added more conditionnals in the code).

2016-07-14drm/nouveau/clk/gk20a: factorize n_lo computation codeAlexandre Courbot
Use a dedicated function instead of always calculating n_lo on the fly. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-14drm/nouveau/clk/gk20a: parameterize PLL settingsAlexandre Courbot
Make functions manipulating PLL settings take them as an argument, instead of assuming we want to work on the copy in the gk20a_clk structure. This makes these functions more flexible, which we will need in GM20B. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-07-14drm/nouveau/clk/gk20a: add and use MNP programming functionsAlexandre Courbot
Add relevant functions to work with the gk20a_pll structure and use them where they ought to be instead of directly manipulating registers. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-07-14drm/nouveau/clk/gk20a: setup slide once during initAlexandre Courbot

2016-07-14drm/nouveau/mc: expose device enable/disable separately, as well as resetBen Skeggs
There are cases where subdevs need to perform additonal actions around the master reset, so we want to expost the operations separately.

2016-07-13drm/exynos: iommu: add support for ARM64 specific code for IOMMU glueMarek Szyprowski
This patch adds support for ARM 64bit architecture with IOMMU-DMA glue code, so Exynos DRM can be now used on Exynos 5433 with IOMMU enabled. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2016-07-13drm/exynos: iommu: move ARM specific code to exynos_drm_iommu.hMarek Szyprowski
This patch moves all ARM 32bit DMA-mapping/IOMMU dependant code from exynos_drm_iommu.c to .h, to let it compile conditionally and prepare for adding support for other architectures/IOMMU glue code (like ARM 64bit with IOMMU-DMA glue). Later, when ARM 32bit and 64bit will be unified, this code can be removed. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2016-07-13drm/exynos: iommu: remove unused entries from exynos_drm_private strcutureMarek Szyprowski
This patch removes unused entries from exynos_drm_private strcuture. da_start/da_space_size were only used in drm_create_iommu_mapping() function and never set to other value than the defaults. Instead use default values directly in arm_iommu_create_mapping() call. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2016-07-13drm/exynos: iommu: add a check if all sub-devices have iommu controllerMarek Szyprowski
This patch adds a check if all devices belonging to Exynos DRM have the same dma_map_ops set. This is required to enable operation with IOMMU enabled. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2016-07-13drm/exynos: iommu: move dma_params configuration code to separate functionsMarek Szyprowski
Move code for managing DMA max segment size parameter to separate functions. This patch also replaces devm_kzalloc() with kzalloc() and adds proper kfree call. devm_kzalloc() cannot be used for dma_params structure, because it will be freed on driver remove not on device release. This means in case of Exynos DRM being compiled as module and loaded 2 times, a user-after-free issue will happen.
