The GRBM register interface is now capable of bursting 1 cycle per register wr->wr, wr->rd much faster than previous muticycle per transaction done interface. This has caused a problem where status registers requiring HW to update have a 1 cycle delay, due to the register update having to go through GRBM. SW may operate on an incorrect value if they write a register and immediately check the corresponding status register. Registers requiring HW to clear or set fields may be delayed by 1 cycle. For example, 1. write VM_INVALIDATE_ENG0_REQ mask = 5a 2. read VM_INVALIDATE_ENG0_ACK till the ack is same as the request mask = 5a a. HW will reset VM_INVALIDATE_ENG0_ACK = 0 until invalidation is complete 3. write VM_INVALIDATE_ENG0_REQ mask = 5a 4. read VM_INVALIDATE_ENG0_ACK till the ack is same as the request mask = 5a a. First read of VM_INVALIDATE_ENG0_ACK = 5a instead of 0 b. Second read of VM_INVALIDATE_ENG0_ACK = 0 because the remote GRBM h/w register takes one extra cycle to be cleared c. In this case, SW will see a false ACK if they exit on first read Affected registers (only GC variant) | Recommended Dummy Read --------------------------------------+---------------------------- VM_INVALIDATE_ENG*_ACK | VM_INVALIDATE_ENG*_REQ VM_L2_STATUS | VM_L2_STATUS VM_L2_PROTECTION_FAULT_STATUS | VM_L2_PROTECTION_FAULT_STATUS VM_L2_PROTECTION_FAULT_ADDR_HI/LO32 | VM_L2_PROTECTION_FAULT_ADDR_HI/LO32 VM_L2_IH_LOG_BUSY | VM_L2_IH_LOG_BUSY MC_VM_L2_PERFCOUNTER_HI/LO | MC_VM_L2_PERFCOUNTER_HI/LO ATC_L2_PERFCOUNTER_HI/LO | ATC_L2_PERFCOUNTER_HI/LO ATC_L2_PERFCOUNTER2_HI/LO | ATC_L2_PERFCOUNTER2_HI/LO Signed-off-by:Xiaojie Yuan <xiaojie.yuan@amd.com> Reviewed-by:

[WHY] value of dchub_ref_clock is decided by dchubbub global timer settings which is programmed by vbios command table disp_init. for multi-GPU case, vbios is posted only for primary GPU. without vbios posted for the secondary GPU, value of dchub_ref_clock is not set properly. this value will affect dcn bandwidth calcuation and cause underflow. user will see screen flicking during driver installation for dual GPU case. [HOW] dc init_hw always call vbios command table disp_init to make sure dchubbub global timer is configured and enable. Signed-off-by:

[Why] The register LVTMA_PWRSEQ_CNTL is used to determine the power state of the embedded display. Currently we do not actually read this register's values, so during power down we think that this display is already off, so we skip calling into VBIOS to actually turn it off.

[why] Before a statically allocated PPS data structure, that did get zeroed-out at startup, had been re-used for making packed PPS SDP. With S3 fix, using a non-initialized PPS data structure was introduced, while wrongly assuming it'd get initialized before it's populated. As a consequence 'vbr_enable' and perhaps some other fields are left uninitialized when making packed PPS SDP. This can affect 'simple_422' as well because of the way PPS SDP packing is done (the fields are not masked first, only shifted). The behavior will be different, depending on the content of uninitialized data.

[Why] Disable_audio_stream gets enum option as a paramenter which will decide if we free acquired resources or not. However checks for the option is guarded by the other condition which check if audio stream is getting diabled more than once.

Currently odm is handled using top_bottom pipe by special casing the differing opps to differentiate from mpc combine. Since top/bottom pipe list was made to track mpc muxing this creates difficulties in adding a 4 pipe odm case support. Rather than continue using mpc combine list, this change reworks odm to use it's own linked list to keep track of odm combine pipes. This also opens up options for using mpo with odm, if a practical use case is ever found. Signed-off-by:
