[Why] When diags adds a DWB via a stream update, we calculate MMHUBBUB paramaters, but dc->current_state has not yet been updated when the DWB programming happens. This leads to overflow on high bandwidth tests since the incorrect MMHUBBUB arbitration parameters are programmed. [How] Pass the updated context down to the (enable|update)_writeback functions so that they can use the correct watermarks when programming MMHUBBUB. Signed-off-by:

[Why] When the driver sends a pipe set command to the DMCU FW, it does not wait for the command to complete. This can lead to unpredictable behavior if, for example, the driver were to request a pipe disable to the FW via MCP, then power down some hardware before the firmware has completed processing the command.

[Why] Type-c PHY config is not align with dpcd lane count. When those values didn't match, it cause driver do link training with 4 lane but phy only can output 2 lane. The link trainig always fail. [How] 1. Modify get_max_link_cap function. According DPALT_DP4 to update max lane count. 2. Add dp_mst_verify_link_cap to handle MST case because we didn't call dp_mst_verify_link_cap for MST case.

Participate in device cgroup. All kfd devices are exposed via /dev/kfd. So use /dev/dri/renderN node. Before exposing the device to a task check if it has permission to access it. If the task (based on its cgroup) can access /dev/dri/renderN then expose the device via kfd node. If the task cannot access /dev/dri/renderN then process device data (pdd) is not created. This will ensure that task cannot use the device. In sysfs topology, all device nodes are visible irrespective of the task cgroup. The sysfs node directories are created at driver load time and cannot be changed dynamically. However, access to information inside nodes is controlled based on the task's cgroup permissions.

For AMD compute (amdkfd) driver. All AMD compute devices are exported via single device node /dev/kfd. As a result devices cannot be controlled individually using device cgroup. AMD compute devices will rely on its graphics counterpart that exposes /dev/dri/renderN node for each device. For each task (based on its cgroup), KFD driver will check if /dev/dri/renderN node is accessible before exposing it. Signed-off-by:

The error handling is off by one. We should not free the first "tables[i].bo" without decrementing "i" because that might result in a double free. The second problem is that when an error occurs, then the zeroth element "tables[0].bo" isn't freed. I had make "i" signed int for the error handling to work, so I just updated "ret" as well as a clean up.
