The RC6 residency time unit is 833.33ns on BXT according to the specification, so update the calculation accordingly. Use the same way as CHV/VLV to divide by the corresponding frequency, as I think this is the more natural unit for what the HW does internally. v2: - add missing IS_BROXTON check (Ville) Testcase: igt/pm_rc6_residency Signed-off-by:

GuC expects two bits for Render and Media domain separately when driver sends data via host2guc SAMPLE_FORCEWAKE. Bit 0 is for Render and bit 1 is for Media domain. v2: Keep sync with code for WaRsDoubleRc6WrlWithCoarsePowerGating v1: Add parameters definition to avoid magic value Signed-off-by:

Added checks for available slices, subslices and EUs for Broadwell. This information is filled in intel_device_info and is available to user with GET_PARAM. Added checks for enabled slices, subslices and EU for Broadwell. This information is based on available counts but takes power gated slices into account. It can be read in debugfs. Introduce new register defines that contain information on slices on Broadwell. v2: - Introduce GT_SLICE_INFO register - Change Broadwell sseu_device_status function to use GT_SLICE_INFO register instead of RPCS register - Undo removal of dev_priv variables in Cherryview and Gen9 sseu_device_satus functions v3: - Fix style issues v4: - Corrected comment - Reverted reordering of defines Cc: Jeff Mcgee <jeff.mcgee@intel.com> Cc: Arun Siluvery <arun.siluvery@linux.intel.com> Signed-off-by:

Previously we've relied on having basically one backlight and one backlight type per platform. This is already a bit quirky with PMIC PWM support on VLV/CHV platforms with MIPI DSI. In the foreseeable future we'll have at least DPCD based backlight control on eDP and DCS command based backlight control on MIPI DSI. Backlight is becoming more and more connector specific, so reflect this fact by making the backlight control hooks connector specific. This enables further work to reuse generic backlight code in intel_panel.c while adding more specific backlight code accessed via the hooks.

It's more useful to limp on than bring the kernel down. Hitting this is a more likely event with BXT DSI, although care should be taken not to call the function for DSI. Signed-off-by:

Replace the use of mem_freq/4 with czclk_freq in the vlv c0 residency calculations. Also deal with VLV_COUNT_RANGE_HIGH which affects all RCx residency counters. We have just enough bits to do this without intermediate divisions. Signed-off-by:

We have the czclk frequency in dev_priv now, so let's just use it when converting the rc6 counters to milliseconds. This eliminates a bunch of hairy code that essentially tries to extract the czclk frequency using yet another method. v2: Fix typos in commit message (Imre) Reviewed-by:

Ville Syrjälä authored
As with the cdclk, read out czclk from CCK as well. This gives us the real current value and avoids having to decode fuses and whatnot. Also store it in kHz under dev_priv like we do for cdlck since it's not just an rps related clock, and having it in kHz is more standard/convenient for some things. Imre also pointed out that we currently fail to read czclk on VLV, which means the PFI credit programming isn't working as expected. Signed-off-by:

Rename the DISPLAY_TRUNK_* and DISPLAY_FREQUENCY_* bits to CCK_... instead of DISPLAY_... to make it clear they apply to all CCK clock control registers. Suggested by Ville. Signed-off-by:

->stolen->start has type u64 aka unsigned long long; relying on the difference (effectively cast to int) for sorting is wrong. It wouldn't be a problem in practice if the values compared are always within INT_MAX of each other (so that the difference is actually representable in an int), but 440fd528 ("drm/mm: Support 4 GiB and larger ranges") strongly suggests that's not the case. Note: atm we don't support more than about 1G of stolen, so this is impossible currenlty. Signed-off-by:
