Rewrite commit 31685c25 Author: Deepak S <deepak.s@linux.intel.com> Date: Thu Jul 3 17:33:01 2014 -0400 drm/i915/vlv: WA for Turbo and RC6 to work together. Other than code clarity, the major improvement is to disable the extra interrupts generated when idle. However, the reclocking remains rather slow under the new manual regime, in particular it fails to downclock as quickly as desired. The second major improvement is that for certain workloads, like games, we need to combine render+media activity counters as the work of displaying the frame is split across the engines and both need to be taken into account when deciding the global GPU frequency as memory cycles are shared.

For SKL, register definition for RPNSWREQ (A008), RPSTAT1(A01C) have changed slightly. Also on SKL, frequency is specified in units of 16.66 MHZ, compared to 50 MHZ for most of the earlier platforms and the time values are expressed in units of 1.33 us, compared to 1.28 us for earlier platforms.

Wrap the FW register value shift+mask operations into a macro to hide the ugliness a bit. Also might avoid bugs due to typos. Also rename all the primary/sprite plane low order bit masks to have the _VLV suffix, so that we can use the FW_WM_VLV() macro instead of the FW_WM() macro for them in a consistent manner. Cursor and all the high order bits are left to use the FW_WM() macro as there's no real confusion with them.

DDR DVFS introduces massive memory latencies which can't be handled by the PND deadline stuff. Instead the watermarks will need to be programmed to compensate for the latency and the deadlines will need to be programmed to tight fixed values. That means DDR DVFS can only be enabled if the display FIFOs are large enough, and that pretty much means we have to manually repartition them to suit the needs of the moment. That's a lot of change, so in the meantime let's just disable DDR DVFS to get the display(s) to be stable.

PFI credit programming is required when CD clock (related to data flow from display pipeline to end display) is greater than CZ clock (related to data flow from memory to display plane). This programming should be done when all planes are OFF to avoid intermittent hangs while accessing memory even from different Gfx units (not just display). If cdclk/czclk >=1, PFI credits could be set as any number. To get better performance, larger PFI credit can be assigned to PND. Otherwise if cdclk/czclk<1, the default PFI credit of 8 should be set. v2: - Change log to lower log level instead of DRM_ERROR - Change function name to valleyview_program_pfi_credits - Move program PFI credits to modeset_init instead of intel_set_mode - Change magic numbers to logical constants [vsyrjala v3: - only program in response to cdclk update - program the credits also when cdclk<czclk - add CHV bits v4: - Change CHV cdclk<czclk credits to 12 (Vijay)] Signed-off-by: NVidya Srinivas <vidya.srinivas@intel.com> Signed-off-by: NGajanan Bhat <gajanan.bhat@intel.com> Signed-off-by: NVandana Kannan <vandana.kannan@intel.com> Signed-off-by: NVille Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: NVijay Purushothaman <vijay.a.purushothaman@linux.intel.com> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>

Assuming the PND deadline mechanism works reasonably we should do memory requests as early as possible so that PND has schedule the requests more intelligently. Currently we're still calculating the watermarks as if VLV/CHV are identical to g4x, which isn't the case. The current code also seems to calculate insufficient watermarks and hence we're seeing some underruns, especially on high resolution displays. To fix it just rip out the current code and replace is with something that tries to utilize PND as efficiently as possible. We now calculate the WM watermark to trigger when the FIFO still has 256us worth of data. 256us is the maximum deadline value supoorted by PND, so issuing memory requests earlier would mean we probably couldn't utilize the full FIFO as PND would attempt to return the data at least in at least 256us. We also clamp the watermark to at least 8 cachelines as that's the magic watermark that enabling trickle feed would also impose. I'm assuming it matches some burst size. In theory we could just enable trickle feed and ignore the WM values, except trickle feed doesn't work with max fifo mode anyway, so we'd still need to calculate the SR watermarks. It seems cleaner to just disable trickle feed and calculate all watermarks the same way. Also trickle feed wouldn't account for the 256us max deadline value, thoguh that may be a moot point in non-max fifo mode sicne the FIFOs are fairly small. On VLV max fifo mode can be used with either primary or sprite planes. So the code now also checks all the planes (apart from the cursor) when calculating the SR plane watermark. We don't have to worry about the WM1 watermarks since we're using the PND deadline scheme which means the hardware ignores WM1 values. v2: Use plane->state->fb instead of plane->fb Signed-off-by: NVille Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: NJesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>

Poke at the CBR1_VLV register during init_clock_gating to make sure the PND deadline scheme is used. The hardware has two modes of operation wrt. watermarks: 1) PND deadline mode: - memory request deadline is calculated from actual FIFO level * DDL - WM1 watermark values are unused (AFAIK) - WM watermark level defines when to start fetching data from memory (assuming trickle feed is not used) 2) backup mode - deadline is based on FIFO status, DDL is unused - FIFO split into three regions with WM and WM1 watermarks, each part specifying a different FIFO status We want to use the PND deadline mode, so let's make sure the chicken bit is in the correct position on init. Also take the opportunity to refactor the shared code between VLV and CHV to a shared function.

Similarly, the count of enabled EU per subslice represents the most enabled EU on any one subslice.
