2020-10-12drm/amd/display: Fix module load hangs when connected to an eDPRodrigo Siqueira1-5/+5
It was recently introduced a change that enables driver to disable streams if pixel clock changes. Consequently, the code path executed in the disable vbios function expanded to an encoder verification part. The encoder loop is nested inside the pipe count loop, and both loops share the 'i' variable in control of their flow. This situation may lead to an infinite loop because the encoder loop constantly updates the `i` variable, making the first loop always positive. As a result, we can see a soft hang during the module load (modprobe amdgpu) and a series of dmesg log that looks like this: kernel:[ 124.538727] watchdog: BUG: soft lockup - CPU#2 stuck for 22s!

As the dpm clock table is needed during DC HW initialization. And that (DC HW initialization) comes before smu_late_init() where current APU dpm clock table setup is performed. So, NULL pointer dereference will be triggered. By moving APU dpm clock table setup to smu_hw_init(), this can be avoided.

2020-10-09drm/amd/pm: Replace one-element array with flexible-array in struct ↵Gustavo A. R. Silva2-9/+5
phm_phase_shedding_limits_table There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Refactor the code according to the use of a flexible-array member in struct phm_phase_shedding_limits_table, instead of a one-element array, and use the struct_size() helper to calculate the size for the allocation. Also, save some heap space as the original code is multiplying ptable->ucNumEntries by sizeof(struct phm_phase_shedding_limits_table) when it should have multiplied it by sizeof(struct phm_phase_shedding_limits_record) instead.
