Try to increase stolen memory size if available in BIOS. random:~$ dmesg | grep -c "Reducing the compressed" 47 This patch makes it DRM_INFO_ONCE() just like the similar message farther down in that function is pr_info_once().

Since moving the obj->vma.list to a spin_lock, and the vm->bound_list to its vm->mutex, along with tracking shrinkable status under its own spinlock, we no long require the object to be locked by the caller.

Fix the warning caused by enabling the autosectionlabel extension in the kernel Sphinx build: Documentation/gpu/i915.rst:610: WARNING: duplicate label gpu/i915:layout, other instance in Documentation/gpu/i915.rst The autosectionlabel extension adds labels to each section title for cross-referencing, but forbids identical section titles in a document. With kernel-doc, this includes sections titles in the included kernel-doc comments. In the warning message, Sphinx is unable to reference the labels in their true locations in the kernel-doc comments in source. In this case, there's "Layout" sections in both gt/intel_workarounds.c and i915_reg.h. Rename the section in the latter to "File Layout".

Right now dp.regs.dp_tp_ctl/status are only set during the encoder pre_enable() hook, what is causing all reads and writes to those registers to go to offset 0x0 before pre_enable() is executed. So if i915 takes the BIOS state and don't do a modeset any following link retraing will fail. In the case that i915 needs to do a modeset, the DDI disable sequence will write to a wrong register not disabling DP 'Transport Enable' in DP_TP_CTL, making a HDMI modeset in the same port/transcoder to not light up the monitor. So here for GENs older than 12, that have those registers fixed at port offset range it is loading at encoder/port init while for GEN12 it will keep setting it at encoder pre_enable() and during HW state readout.

TC ports can enter in TCCOLD to save power and is required to request to PCODE to exit this state before use or read to TC registers. For TGL there is a new MBOX command to do that with a parameter to ask PCODE to exit and block TCCOLD entry or unblock TCCOLD entry. So adding a new power domain to reuse the refcount and only allow TC cold when all TC ports are not in use. v2: - fixed missing case in intel_display_power_domain_str() - moved tgl_tc_cold_request to intel_display_power.c - renamed TGL_TC_COLD_OFF to TGL_TC_COLD_OFF_POWER_DOMAINS - added all TC and TBT aux power domains to TGL_TC_COLD_OFF_POWER_DOMAINS v3: - added one msec sleep when PCODE returns -EAGAIN - added timeout of 5msec to not loop forever if sandybridge_pcode_write_timeout() keeps returning -EAGAIN v4: - Made failure to block or unblock TC cold a error - removed 5msec timeout, instead giving PCODE 1msec by up 3 times to recover from the internal error v5: - only sleeping 1msec when ret is -EAGAIN BSpec: 49294 Cc: Imre Deak <imre.deak@intel.com> Cc: Cooper Chiou <cooper.chiou@intel.com> Cc: Kai-Heng Feng <kai.heng.feng@canonical.com> Reviewed-by:

As part of ICL TC cold exit sequences we need to request aux power well before lock the access to TC ports, so skiping the intel_tc_port_ref_held() check for TC legacy ports. Reviewed-by:

José Roberto de Souza authored
This is required for legacy/static TC ports as IOM is not aware of the connection and will not trigger the TC cold exit. Just request PCODE to exit TCCOLD is not enough as it could enter again before driver makes use of the port, to prevent it BSpec states that aux powerwell should be held. So here embedding the TC cold exit sequence into ICL aux enable, it will enable aux and then request TC cold to exit. The TC cold block(exit and aux hold) and unblock was added to some exported TC functions for the others and to access PHY registers, callers should enable and keep aux powerwell enabled during access. Also adding TC cold check and warnig in tc_port_load_fia_params() as at this point of the driver initialization we can't request power wells, if we get this warning we will need to figure out how to handle it. v2: - moved ICL TC cold exit function to intel_display_power - using dig_port->tc_legacy_port to only execute sequences for legacy ports, hopefully VBTs will have this right - fixed check to call _hsw_power_well_continue_enable() - calling _hsw_power_well_continue_enable() unconditionally in icl_tc_phy_aux_power_well_enable(), if needed we will surpress timeout warnings of TC legacy ports - only blocking TC cold around fia access v3: - added timeout of 5msec to not loop forever if sandybridge_pcode_write_timeout() keeps returning -EAGAIN returning -EAGAIN in in icl_tc_cold_exit() - removed leftover tc_cold_wakeref - added one msec sleep when PCODE returns -EAGAIN v4: - removed 5msec timeout, instead giving 1msec to whoever is using PCODE to finish it up to 3 times - added a comment about turn TC cold exit failure as a error in future BSpec: 21750 Closes: https://gitlab.freedesktop.org/drm/intel/issues/1296 Cc: Imre Deak <imre.deak@intel.com> Cc: Cooper Chiou <cooper.chiou@intel.com> Cc: Kai-Heng Feng <kai.heng.feng@canonical.com> Reviewed-by:

A basic premise of RPS is that at lower frequencies, not only do we run slower, but we save power compared to higher frequencies. For example, when idle, we set the minimum frequency just in case there is some residual current. Since the power curve should be a physical relationship, if we find no power saving it's likely that we've broken our frequency handling, so test! Signed-off-by:

Lets have a unified way to handle SAGV changes, espoecially considering the upcoming Gen12 changes. Current "standard" way of doing this in commit_tail is pre/post plane updates, when everything which has to be forbidden and not supported in new config has to be restricted before update and relaxed after plane update. v2: - Removed unneeded returns(Ville) Reviewed-by:

Since we are touching the device to read the registers, we are required to ensure the device is awake at the time.

It seems that although (perhaps because of the memory stall?) the spinner has signaled that it has started, it still takes some time to spin up to 100% utilisation of the HW. Since the test depends on the full utilisation of the HW to trigger the RPS interrupt, wait a little bit and flush the interrupt status to be sure that the event we see if from the spinner.

Before we resume, we reset the HW so we restart from a known good state. However, as a part of the reset process, we drain our pending CS event queue -- and if we are resuming that does not correspond to internal state. On setup, we are scrubbing the CS pointers, but alas only on setup. Apply the sanitization not just to setup, but to all resumes. Reported-by:

For certain DP VDSC bpp settings, hblank asserts before hblank_early, leading to a bad audio state. Driver need to program "hblank early enable" and "samples per line" parameters in AUDIO_CONFIG_BE register. This is Display Audio WA #1406928334 for 4k+VDSC usecase applicable on DP encoders. Implemented the same. v2: Fixed build failures on 32bit machine. v3: Dropped u64, added helpers for sample room calculation, other general comments as per Jani Nikula's feedback. Also fixed connector type check (spotted by Anshuman) v4: Addressed Jani Nikula and Kai's review comments. v5: Addressed Anshuman's review comment and used crtc_* variable to get timings. v6: Dropped a redundant initialization.

Gen11 onwards PG3 is contains functions for pipe B, external displays, and VGA. It make sense to add a power well id with name ICL_DISP_PW_3 rather then TGL_DISP_PW_3, Also PG3 power well id requires to know if lpsp is enabled. Reviewed-by:
