2016-02-12drm/dp: Add a drm_aux-dev module for reading/writing dpcd registers.Rafael Antognolli6-2/+468
This module is heavily based on i2c-dev. Once loaded, it provides one dev node per DP AUX channel, named drm_dp_auxN, where N is an integer. It's possible to know which connector owns this aux channel by looking at the respective sysfs /sys/class/drm_aux_dev/drm_dp_auxN/connector, if the connector device pointer was correctly set in the aux helper struct. Two main operations are provided on the registers read and write. The address of the register to be read or written is given using lseek. The seek position is updated upon read or write. v2: - lseek is used to select the register to read/write - read/write are used instead of ioctl - no blocking_notifier is used, just a direct callback v3: - use drm_dp_aux_dev prefix for public functions - chardev is named drm_dp_auxN - read/write don't allocate a buffer anymore, and transfer up to 16 bytes a time - remove notifier list from the implementation - option on menuconfig is now a boolean - add inline stub functions to avoid breakage when this option is disabled v4: - fix build system changes - actually disable this module when not selected. v5: - Use kref to avoid device closing while still in use - Don't use list, use an idr for storing aux_dev - Remove "connector" attribute - set aux.dev to the connector drm_connector device, instead of drm_device v6: - Use atomic_t for usage count - Use a mutex instead of spinlock for idr lock - Destroy chardev immediately on unregister - other minor suggestions from Ville v7: - style fixes - error handling fixes v8: - more error handling fixes v9: - remove module_init and module_exit, and add drm_dp_aux_dev_init/exit to drm_kms_helper_init/exit.

2016-02-10drm/radeon: Avoid double gpu reset by adding a timeout on IB ring tests.Matthew Dawson9-23/+89
When the radeon driver resets a gpu, it attempts to test whether all the rings can successfully handle an IB. If these rings fail to respond, the process will wait forever. Another gpu reset can't happen at this point, as the current reset holds a lock required to do so. Instead, make all the IB tests run with a timeout, so the system can attempt to recover in this case. While this doesn't fix the underlying issue with card resets failing, it gives the system a higher chance of recovering. These timeouts have been confirmed to help both a Tathi and Hawaii card recover after a gpu reset. This also adds a new function, radeon_fence_wait_timeout, that behaves like fence_wait_timeout. It is used instead of fence_wait_timeout as it continues to work during a reset. radeon_fence_wait is changed to be implemented using this function. V2: - Changed the timeout to 1s, as the default 10s from radeon_wait_timeout was too long. A timeout of 100ms was tested and found to be too short. - Changed radeon_fence_wait_timeout to behave more like fence_wait_timeout.
