2019-07-18smb3: optimize open to not send query file internal infoSteve French
We can cut one third of the traffic on open by not querying the inode number explicitly via SMB3 query_info since it is now returned on open in the qfid context. This is better in multiple ways, and speeds up file open about 10% (more if network is slow). Reviewed-by: Pavel Shilovsky <pshilov@microsoft.com> Signed-off-by: Steve French <stfrench@microsoft.com>

2019-07-18drm/amd/display: Copy GSL groups when committing a new contextNicholas Kazlauskas
[Why] DC configures the GSL group for the pipe when pipe_split is enabled and we're switching flip types (buffered <-> immediate flip) on DCN2. In order to record what GSL group the pipe is using DC stores it in the pipe's stream_res. DM is not aware of this internal grouping, nor is DC resource. So when DM creates a dc_state context and passes it to DC the current GSL group is lost - DM never knew about it in the first place. After 3 immediate flips we run out of GSL groups and we're no longer able to correctly perform *any* flip for multi-pipe scenarios. [How] The gsl_group needs to be copied to the new context. DM has no insight into GSL grouping and could even potentially create a brand new context without referencing current hardware state. So this makes the most sense to have happen in DC. There are two places where DC can apply a new context: - dc_commit_state - dc_commit_updates_for_stream But what's shared between both of these is apply_ctx_for_surface. This logic only matters for DCN2, so it can be placed in dcn20_apply_ctx_for_surface. Before doing any locking (where the GSL group is setup) we can copy over the GSL groups before committing the new context.

2019-07-18drm/amd/display: support "dummy pstate"Jun Lei
[why] Existing support in DC for pstate only accounts for a single latency. This is sufficient when the variance of latency is small, or that pstate support isn't necessary for correct ASIC functionality. Newer ASICs violate both existing assumptions. PState support is mandatory of correct ASIC functionality, but not all latencies have to be supported. Existing code supports a "full p state" which allows memory clock to change, but is hard for DCN to support (as it requires very large buffers). New code will now fall back to a "dummy p state" support when "full p state" cannot be support. This easy p state support should always be allowed. [how] Define a new latency in socBB.

[Why] In an effort to stop redundant calls to dce110_disable_audio_stream the audio->enabled flag was added to the audio resource struct. While this state probably shouldn't have been tracked on the audio struct itself it still works fine for some sequences. However, it does not work for cases where we're freeing the audio resource (such as hotplugs) or when dynamic audio is enabled. In these cases the pipe_ctx->stream_res.audio = NULL before we can set audio->enabled = false. The next time we acquire the audio resource such as on hotplug the audio will not be enabled for the stream since DC thinks it's still enabled. Audio state tracking should cover this sequence.

2019-07-18drm/amd/display: Clear FEC_READY shadow register if DPCD write failsNikola Cornij
[why] As a fail-safe, in case 'set FEC_READY' DPCD write fails, a HW shadow register should be cleared and the internal FEC stat should be set to 'not ready'. This is to make sure HW settings will be consistent with FEC_READY state on the RX.

2019-07-18drm/amd/display: Optimize gamma calculationsKrunoslav Kovac
[Why&How] 1. Stack usage is pretty high as fixed31_32 struct is 8 bytes and we have functions with >30 vars on the stack. 2. Optimize gamma calculation by reducing number of calls to dc_fixpt_pow Our X points are divided into 32 regions wth 16 pts each. Each region is 2x the previous, meaning x[i] = 2*x[i-16] for i>=16. Using (2x)^gamma = 2^gamma * x^gamma, we can recursively compute powers of gamma, we just need first 16 pts to start it up. dc_fixpt_pow() is expensive, it computes x^y by doing exp(y*logx) Exp is done by Taylor series approximation, and log by Newton-like approximation that also uses exp internally. In short, it's significantly heavier than run-of-the-mill addition/subtraction/multiply.
