Before the patch, intel_device_info_get_max_preferred_slm_size()
returns values in kilobytes, but then
intel_device_info_get_max_slm_size() is multiplying it by 1024.
As a result, LNL is reporting maxComputeSharedMemorySize to be
134217728, which is 128mb.
Fix this by making intel_device_info_get_max_slm_size() not multiply
it by 1024.
This should fix at least the following dEQP tests:
dEQP-VK.compute.pipeline.zero_initialize_workgroup_memory.max_workgroup_memory.1
dEQP-VK.compute.pipeline.zero_initialize_workgroup_memory.max_workgroup_memory.128
dEQP-VK.compute.pipeline.zero_initialize_workgroup_memory.max_workgroup_memory.16
dEQP-VK.compute.pipeline.zero_initialize_workgroup_memory.max_workgroup_memory.2
dEQP-VK.compute.pipeline.zero_initialize_workgroup_memory.max_workgroup_memory.4
dEQP-VK.compute.pipeline.zero_initialize_workgroup_memory.max_workgroup_memory.64
Some tests were failing with:
deqp-vk: ../../src/intel/common/intel_compute_slm.c:24: slm_encode_lookup: Assertion `kbytes <= table[table_len - 1].size_in_kb' failed.
while other tests were triggering the OOM.
v2:
- Make everybody return sizes in bytes (José).
v3:
- Rename variable to bytes (José, Jordan).
