2021-02-22drm/i915/edp: read sink MSO configuration for eDP 1.4+Jani Nikula2-0/+35
Read and debug log the eDP sink MSO configuration. Do not actually do anything with the information yet besides logging. FIXME: The pixel overlap is present in DisplayID 2.0, but we don't have parsing for that. Assume zero for now. We could also add quirks for non-zero pixel overlap before DisplayID 2.0 parsing. v3: Add placeholder for pixel overlap. v2: Rename intel_dp_mso_init -> intel_edp_mso_init Cc: Nischal Varide <nischal.varide@intel.com> Reviewed-by: Uma Shankar <uma.shankar@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/24ef61574e5af12cd86d5b85afbfbd4ac2f9de25.1613054234.git.jani.nikula@intel.com

2021-02-22drm/i915/display: Set source_support even if panel do not support PSRJosé Roberto de Souza1-3/+0
This will set the right value of source_support when the port encoder/port supports PSR but sink don't.

intel_psr2_program_trans_man_trk_ctl() There is no support for two pipes one transcoder for PSR and if we had that the current code should not use cpu_transcoder. Also I can't see a scenario where crtc_state->enable_psr2_sel_fetch is set and PSR is not enabled and if by a bug it happens PSR HW will just ignore any value in set in PSR2_MAN_TRK_CTL. So dropping all the rest and keeping the same behavior that we have with intel_psr2_program_plane_sel_fetch().

Specifics: - Add new power capping facility called DTPM (Dynamic Thermal Power Management), based on the existing power capping framework, to allow aggregate power constraints to be applied to sets of devices in a distributed manner, along with a CPU backend driver based on the Energy Model (Daniel Lezcano, Dan Carpenter, Colin Ian King). - Add AlderLake Mobile support to the Intel RAPL power capping driver and make it use the topology interface when laying out the system topology (Zhang Rui, Yunfeng Ye). - Drop the cpufreq tango driver belonging to a platform that is not supported any more (Arnd Bergmann). - Drop the redundant CPUFREQ_STICKY and CPUFREQ_PM_NO_WARN cpufreq driver flags (Viresh Kumar). - Update cpufreq drivers: * Fix max CPU frequency discovery in the intel_pstate driver and make janitorial changes in it (Chen Yu, Rafael Wysocki, Nigel Christian). * Fix resource leaks in the brcmstb-avs-cpufreq driver (Christophe JAILLET). * Make the tegra20 driver use the resource-managed API (Dmitry Osipenko). * Enable boost support in the qcom-hw driver (Shawn Guo). - Update the operating performance points (OPP) framework: * Clean up the OPP core (Dmitry Osipenko, Viresh Kumar). * Extend the OPP API by adding new helpers to it (Dmitry Osipenko, Viresh Kumar). * Allow required OPPs to be used for devfreq devices and update the devfreq governor code accordingly (Saravana Kannan). * Prepare the framework for introducing new dev_pm_opp_set_opp() helper (Viresh Kumar). * Drop dev_pm_opp_set_bw() and update related drivers (Viresh Kumar). * Allow lazy linking of required-OPPs (Viresh Kumar). - Simplify and clean up devfreq somewhat (Lukasz Luba, Yang Li, Pierre Kuo). - Update the generic power domains (genpd) framework: * Use device's next wakeup to determine domain idle state (Lina Iyer). * Improve initialization and debug (Dmitry Osipenko). * Simplify computations (Abaci Team). - Make janitorial changes in the core code handling system sleep and PM-runtime (Bhaskar Chowdhury, Bjorn Helgaas, Rikard Falkeborn, Zqiang). - Update the MAINTAINERS entry for the exynos cpuidle driver and drop DEBUG definition from intel_idle (Krzysztof Kozlowski, Tom Rix). - Extend the PM clock layer to cover clocks that must sleep (Nicolas Pitre). - Update the cpupower utility: * Update cpupower command, add support for AMD family 0x19 and clean up the code to remove many of the family checks to make future family updates easier (Nathan Fontenot, Robert Richter). * Add Makefile dependencies for install targets to allow building cpupower in parallel rather than serially (Ivan Babrou). - Make janitorial changes in power management Kconfig (Lukasz Luba)" * tag 'pm-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (89 commits) MAINTAINERS: cpuidle: exynos: include header in file pattern powercap: intel_rapl: Use topology interface in rapl_init_domains() powercap: intel_rapl: Use topology interface in rapl_add_package() PM: sleep: Constify static struct attribute_group PM: Kconfig: remove unneeded "default n" options PM: EM: update Kconfig description and drop "default n" option cpufreq: Remove unused flag CPUFREQ_PM_NO_WARN cpufreq: Remove CPUFREQ_STICKY flag PM / devfreq: Add required OPPs support to passive governor PM / devfreq: Cache OPP table reference in devfreq OPP: Add function to look up required OPP's for a given OPP PM / devfreq: rk3399_dmc: Remove unneeded semicolon opp: Replace ENOTSUPP with EOPNOTSUPP opp: Fix "foo * bar" should be "foo *bar" opp: Don't ignore clk_get() errors other than -ENOENT opp: Update bandwidth requirements based on scaling up/down opp: Allow lazy-linking of required-opps opp: Remove dev_pm_opp_set_bw() devfreq: tegra30: Migrate to dev_pm_opp_set_opp() drm: msm: Migrate to dev_pm_opp_set_opp() ...
2021-02-20drm/i915/vbt: update DP max link rate tableLee Shawn C2-21/+60
According to Bspec #20124, max link rate table for DP was updated at BDB version 230. Max link rate can support upto UHBR. After migrate to BDB v230, the definition for LBR, HBR2 and HBR3 were changed. For backward compatibility. If BDB version was from 216 to 229. Driver have to follow original rule to configure DP max link rate value from VBT. v2: split the mapping table to two for old and new BDB definition. v3: return link rate instead of assigning it. v4: remove the useless variable.

2021-02-19drm/amd/display: Fix MPC OGAM power on/off sequenceNicholas Kazlauskas1-11/+13
[Why] Color corruption can occur on bootup into a login manager that applies a non-linear gamma LUT because the LUT may not actually be powered on before writing. It's cleared on the next full pipe reprogramming as we switch to LUTB from LUTA and the pipe accessing the LUT has taken it out of light sleep mode. [How] The MPCC_OGAM_MEM_PWR_FORCE register does not force the current power mode when set to 0. It only forces when set light sleep, deep sleep or shutdown. The register to actually force power on and ignore sleep modes is MPCC_OGAM_MEM_PWR_DIS - a value of 0 will enable power requests and a value of 1 will disable them. When PWR_FORCE!=0 is combined with PWR_DIS=0 then MPCC OGAM memory is forced into the state specified by the force bits. If PWR_FORCE is 0 then it respects the mode specified by MPCC_OGAM_MEM_LOW_PWR_MODE if the RAM LUT is not in use. We set that bit to shutdown on low power, but otherwise it inherits from bootup defaults. So for the fix: 1. Update the sequence to "force" power on when needed We can use MPCC_OGAM_MEM_PWR_DIS for this to turn on the memory even when the block is in bypass and pending to be enabled for the next frame. We need this for both low power enabled or disabled. If we don't set this then we can run into issues when we first program the LUT from bootup. 2. Don't apply FORCE_SEL Once we enable power requests with DIS=0 we run into the issue of the RAM being forced into light sleep and being unusable for display output. Leave this 0 like we used to for DCN20. 3. Rely on MPCC OGAM init to determine light sleep/deep sleep MPC low power debug mode isn't enabled on any ASIC currently but we'll respect the setting determined during init if it is. Lightly tested as working with IGT tests and desktop color adjustment. 4. Change the MPC resource default for DCN30 It was interleaving the dcn20 and dcn30 versions before depending on the sequence. 5. REG_WAIT for it to be on whenever we're powering up the memory Otherwise we can write register values too early and we'll get corruption.
