The function dcn32_helper_populate_phantom_dlg_params uses FPU operations. For this reason, this commit moves this function to the dcn32_fpu file, and we ensure that we only invoke it under the kernel_fpu protection. Tested-by:

Use the former pad element to store the IP versions from the IP discovery table. This allows userspace to get the IP version from the kernel to better align with hardware IP versions.

We are working to isolate FPU operations inside the DML folder, and the file dcn32_clk_mgr has some of these operations. This commit moves the FPU operations inside the clock manager and creates the dcn32_fpu file to aggregate those operations. Note that there is no functional change ere, just moving code from one part to another. Tested-by:

[why] Unbounded request logic in resource/DML has some issues where unbounded request is being enabled incorrectly. SW today enables unbounded request unconditionally in hardware, on the assumption that HW can always support it in single pipe scenarios. This worked until now because the same assumption is made in DML. A new DML update is needed to fix a bug, where there are single pipe scenarios where unbounded cannot be enabled, and this change in DML needs to be ported in, and dcn32 resource logic fixed. [how] First, dcn32_resource should program unbounded req in HW according to unbounded req enablement output from DML, as opposed to DML input. Second, port in DML update which disables unbounded req in some scenarios to fix an issue with poor stutter performance Tested-by:

André Almeida authored
GFXOFF has two different "state" values: one to define if the GPU is allowed/disallowed to enter GFXOFF, usually called state; and another one to define if currently GFXOFF is being used, usually called status. Even when GFXOFF is allowed, GPU firmware can decide to not used it accordingly to the GPU load. Userspace can allow/disallow GPUs to enter into GFXOFF via debugfs. The kernel maintains a counter of requests for GFXOFF (gfx_off_req_count) that should be decreased to allow GFXOFF and increased to disallow. The issue with this interface is that userspace can't be sure if GFXOFF is currently allowed. Even by checking amdgpu_gfxoff file, one might get an ambiguous 2, that means that GPU is currently out of GFXOFF, but that can be either because it's currently disallowed or because it's allowed but given the current GPU load it's enabled. Then, userspace needs to rely on the fact that GFXOFF is enabled by default on boot and to track this information. To make userspace life easier and GFXOFF more reliable, return the current state of GFXOFF to userspace when reading amdgpu_gfxoff with the same semantics of writing: 0 means not allowed, not 0 means allowed. Expose the current status of GFXOFF through a new file, amdgpu_gfxoff_status. Signed-off-by:

We want to calculate the DTB clock values when DSC is enabled; however, this is not the current behavior implemented in DCN32.

[why] Number of DSC slices is an input to DML with high dependency on display specific capability. This isn't something DML can decide on its own. DML has to use the original number of DSC slices input to DML during validation without modification. Otherwise the computed DSC delay will not reflect the current configuration and therefore causes validation failures. [how] Remove DML override for number of DSC slices parameter. Tested-by:
