2021-08-26drm/i915: Ensure wa_init_finish() is called for ctx workaround listMatt Roper
A recent restructuring of our context workaround list initialization added an early return for non-render engines; this caused us to potentially miss the wa_init_finish() call at the end of the function. The mistake is pretty harmless --- the only impact is that non-render engines on graphics version 12.50+ platforms we don't trim down the workaround list to reclaim some memory, and we don't print the usual "Initialized 1 context workaround" message in dmesg. Let's change the early return to a jump down to the wa_init_finish() call at the bottom of the function.

2021-08-26drm/amdkfd: Account for SH/SE count when setting up cu masks.Sean Keely
On systems with multiple SH per SE compute_static_thread_mgmt_se# is split into independent masks, one for each SH, in the upper and lower 16 bits. We need to detect this and apply cu masking to each SH. The cu mask bits are assigned first to each SE, then to alternate SHs, then finally to higher CU id. This ensures that the maximum number of SPIs are engaged as early as possible while balancing CU assignment to each SH. v2: Use max SH/SE rather than max SH in cu_per_sh. v3: Fix comment blocks, ensure se_mask is initially zero filled, and correctly assign se.sh.cu positions to unset bits in cu_mask.

2021-08-25drm/i915/dg2: Memory latency values from pcode must be doubledMatt Roper
The memory latency values returned by pcode on DG2 are in units of "2 usec" rather than 1 usec on all other platforms. I.e., we need to double the value returned by pcode to obtain the true latency value. The bspec wording here was a bit ambiguous as to whether it wanted us to multiply or divide the pcode value by two, but we confirmed offline with the hardware team that we need to double the value the pcode gives us; this change is intended to support a larger range of potential latency values.

2021-08-25drm/panfrost: Clamp lock region to Bifrost minimumAlyssa Rosenzweig
When locking a region, we currently clamp to a PAGE_SIZE as the minimum lock region. While this is valid for Midgard, it is invalid for Bifrost, where the minimum locking size is 8x larger than the 4k page size. Add a hardware definition for the minimum lock region size (corresponding to KBASE_LOCK_REGION_MIN_SIZE_LOG2 in kbase) and respect it.

2021-08-25drm/panfrost: Use u64 for size in lock_regionAlyssa Rosenzweig
Mali virtual addresses are 48-bit. Use a u64 instead of size_t to ensure we can express the "lock everything" condition as ~0ULL without overflow. This code was silently broken on any platform where a size_t is less than 48-bits; in particular, it was broken on 32-bit armv7 platforms which remain in use with panfrost.

2021-08-25drm/panfrost: Simplify lock_region calculationAlyssa Rosenzweig
In lock_region, simplify the calculation of the region_width parameter. This field is the size, but encoded as ceil(log2(size)) - 1. ceil(log2(size)) may be computed directly as fls(size - 1). However, we want to use the 64-bit versions as the amount to lock can exceed 32-bits. This avoids undefined (and completely wrong) behaviour when locking all memory (size ~0). In this case, the old code would "round up" ~0 to the nearest page, overflowing to 0. Since fls(0) == 0, this would calculate a region width of 10 + 0 = 10. But then the code would shift by (region_width - 11) = -1. As shifting by a negative number is undefined, UBSAN flags the bug. Of course, even if it were defined the behaviour is wrong, instead of locking all memory almost none would get locked. The new form of the calculation corrects this special case and avoids the undefined behaviour.
