ast_get_dram_info() configures a window in order to access BMC memory. A BMC register can be configured to disallow this, and if so, causes an infinite loop in the ast driver which renders the system unusable. Fix this by erroring out if an error is detected. On powerpc systems with EEH, this leads to the device being fenced and the system continuing to operate. Cc: <stable@vger.kernel.org> # 3.10+ Signed-off-by:

Currently, every backlight interface created by Nouveau uses the same name, nv_backlight. This leads to a sysfs warning as it tries to create an already existing folder. This patch adds a incremented number to the name, but keeps the initial name as nv_backlight, to avoid possibly breaking userspace; the second interface will be named nv_backlight1, and so on. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=86539 v2: * Switch to using ida for generating unique IDs, as suggested by Ilia Mirkin; * Allocate backlight name on the stack, as suggested by Ilia Mirkin; * Move `nouveau_get_backlight_name()` to avoid forward declaration, as suggested by Ilia Mirkin; * Fix reference to bug report formatting, as reported by Nick Tenney. v3: * Define a macro for the size of the backlight name, to avoid defining it multiple times; * Use snprintf in place of sprintf. v4: * Do not create similarly named interfaces when reaching the maximum amount of unique names, but fail instead, as pointed out by Lukas Wunner Signed-off-by:

TTM was changed a while back to allow for pipelining of buffer moves, and part of this was the removal of waiting for a BO to idle before calling move(), placing the responsibility on the driver to do this if required. That's all well and good, except, we make use of move_notify() to handle mapping/unmapping from the GPU VMM as move() isn't called on all paths. This commit adds a wait before unmapping from a VMM in move_notify(), to prevent GPU page faults where a buffer is still being accessed. Signed-off-by: -

This has been on the TODO list for a while now, recovering from things such as attempting to execute a push buffer or touch a semaphore in an unmapped memory area. The only thing required on the HW side here is that the offending channel is removed from the runlist, and *not* a full reset of PFIFO. This used to be a bit messier to handle before the rework to make use of engine topology info, but is apparently now trivial. Signed-off-by:

We thought that no userspace is using them, but oops libdrm is using them to figure out whether a driver supports modesetting. Check out drmCheckModesettingSupported but maybe don't because it's horrible and totally runs counter to where we want to go with libdrm device handling. The function looks in the device hierarchy for whether controlD* exist using the following format string: /sys/bus/pci/devices/%04x:%02x:%02x.%d/drm/controlD%d The "/drm" subdirectory is the glue directory from the sysfs class stuff, and the only way to get at it seems to through kdev->kobj.parent (when kdev is represents e.g. the card0 chardev instance in sysfs). Git grep says we're not the only ones touching that, so I hope it's ok we dig into such internals - I couldn't find a proper interface for getting at the glue directory. Quick git grep shows that at least -amdgpu, -ati are using this. -modesetting do not, and on -intel it's only about the 4th fallback path for device lookup, which is why this didn't blow up earlier. Oh well, we need to keep it working, and the simplest way is to add a symlink at the right place in sysfs from controlD* to card*. v2: - Fix error path handling by adding if (!minor) return checks (David) - Fix the controlD* numbers to match what's been there (David) - Add a comment what exactly userspace minimally needs. - Correct the analysis for -intel (Chris).

Some generic TV connector properties are exposed in drm_mode_config, but they are currently handled independently in each DRM encoder driver. Extend the drm_connector_state to store TV related states, and modify the drm_atomic_connector_{set,get}_property() helpers to fill the connector state accordingly. Each driver is then responsible for checking and applying the new config in its ->atomic_mode_{check,set}() operations. Signed-off-by: -

For CZ, some function pointers like display_configuration_changed are not set. So when HW manager tries to configure display, we end up with messages like "[ powerplay ] this function not implement!" in the logs. This message is informational, but lacks details on which function is not implemented and why. Rather than using KERN_INFO to print the message everytime the system boots, we rather use pr_debug so that it is only printed when debug prints are enabled at runtime. Reviewed-by:

We set the possible_crtc for all planes to "(1 << priv->num_crtcs) - 1", which is fine as the HW planes can be used fro all crtcs. However, when we're doing that, we are still incrementing 'num_crtcs', and we'll end up with bad possible_crtcs, preventing the use of the primary planes. This patch passes a possible_crtcs mask to plane init function so that we get correct possible_crtc. Signed-off-by: -
