The code attempts to enable them, but hits an undefined behaviour by shifting by the entire register's width: int lines = 32; u32 mask = (1 << lines) - 1; // 00000000 on x86 u32 mask = (1 << lines) - 1; // ffffffff on arm (32) u32 mask = (1 << lines) - 1; // 00000000 on arm64 u32 mask = (1ULL << lines) - 1; // ffffffff everywhere Signed-off-by:Adam Borowski <kilobyte@angband.pl> Signed-off-by:

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:

GP10B's MC is compatible with GP100's, but engines need to be explicitly put out of ELPG during init. Signed-off-by:

The GP10B firmware is very close to GM20B's. The only difference is that it supports booting multiple falcons. In order to avoid having too much functions and structures shared, implement its support in the same source file as GM20B firmware. Signed-off-by:

GP10B's secboot is largely similar to GM20B's. Only differences are MC base address and the fact that GPCCS is also securely managed. Signed-off-by:

Alexandre Courbot authored
Allow the MC base address to be specified as an argument for the WPR region reading function. GP10B uses a different address layout as GM20B, so this is necessary. Also export the function to be used by GP10B. Signed-off-by:

The LS firmware post-run hook is the right place to start said LS firmware. Moving it here also allows to remove special handling in the ACR code. Signed-off-by:

A LS post-run hook can meet an error meaning the failure of secure boot. Make sure this can be reported. Signed-off-by:
-
Alexandre Courbot authored
Having access to the secboot instance loading a LS firmware can be useful to LS firmware handlers. At least more useful than just having an out-of-context subdev pointer. GP10B's firmware will also need to know the WPR address, which can be obtained from the secboot instance. Signed-off-by:

Alexandre Courbot authored
Change the secboot and msgqueue interfaces to take a mask of falcons to reset instead of a single falcon. The GP10B firmware interface requires FECS and GPCCS to be booted in a single firmware command. For firmwares that only support single falcon boot, it is trivial to loop over the mask and boot each falcons individually. Signed-off-by:

The gk20a implementation of instance memory uses vmap()/vunmap() to map memory regions into the kernel's virtual address space. These functions may sleep, so protecting them by a spin lock is not safe. This triggers a warning if the DEBUG_ATOMIC_SLEEP Kconfig option is enabled. Fix this by using a mutex instead.

When the atomic support was added to nouveau, the DRM core did not do this. However, later in the same merge window, a commit (drm/fence: add in-fences support) was merged that added it, leading to use-after-frees of the fence object. Cc: stable@vger.kernel.org [4.10+] Signed-off-by: -

The NV4A (aka NV44A) is an oddity in the family. It only comes in AGP and PCI varieties, rather than a core PCIE chip with a bridge for AGP/PCI as necessary. As a result, it appears that the MMU is also non-functional. For AGP cards, the vast majority of the NV4A lineup, this worked out since we force AGP cards to use the nv04 mmu. However for PCI variants, this did not work. Switching to the NV04 MMU makes it work like a charm. Thanks to mwk for the suggestion. This should be a no-op for NV4A AGP boards, as they were using it already. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=70388Signed-off-by:

Unlike the connector type, the encoder type is unused by userspace. As it is equally unused in the driver, except in a single location where the connector type can be used instead, hardcode it to DRM_MODE_ENCODER_NONE. This allow removing all code that tries to determine (unsuccessfully in case a bridge is used) the encoder type. Signed-off-by: -

Retrieve the LVDS mode from the panel and configure the LVDS encoder accordingly. LVDS mode selection is static as LVDS panels can't be hot-plugged on any of the device supported by the driver. Support for dynamic mode selection can be implemented in the future when needed. Signed-off-by: -

On Gen3 platforms planes are managed by the external VSP compositor on behalf of DRM/KMS. If VSP compositor support is not enabled in the DU driver, the VSP initialization stub routine is called. Return an error from that stub to fail explicitly, otherwise the device won't be usable and the driver will crash. Signed-off-by:
