Normally i85x/i865 3D activity will block FBC until a 2D blit occurs. I suppose this was meant to avoid recompression while 3D activity is still going on but the frame hasn't yet been presented. Unfortunately that also means that a page flipped 3D workload will permanently block FBC even if it only renders a single frame and then does nothing. Since we are using software render tracking anyway we might as well flip the chicken bit so that 3D does not block FBC. This will avoid the permament FBC blockage in the aforemention use case, but thanks to the software tracking the compressor will not disturb 3D rendering activity.

Rocket Lake uses the same 'abox0' mechanism to handle pixel data transfers from memory that gen11 platforms used, rather than the abox1/abox2 interfaces used by TGL/DG1. For the most part this is a hardware implementation detail that's transparent to driver software, but we do have to program a couple of tuning registers (MBUS_ABOX_CTL and BW_BUDDY registers) according to which ABOX instances are used by a platform. Let's track the platform's ABOX usage in the device info structure and use that to determine which instances of these registers to program. As an exception to this rule is that even though TGL/DG1 use ABOX1+ABOX2 for data transfers, we're still directed to program the ABOX_CTL register for ABOX0; so we'll handle that as a special case. v2: - Store the mask of platform-specific abox registers in the device info structure. - Add a TLB_REQ_TIMER() helper macro. (Aditya) v3: - Squash ABOX and BW_BUDDY patches together and use a single mask for both of them, plus a special-case for programming the ABOX0 instance on all gen12.

I've checked a bunch of gen3/4 machines and all seem to have consistent FSB frequency information in the CLKCFG register. So let's read out hrawclk on all gen3+ machines. Although apart from g4x/pnv aux/pps dividers we only really need this for for i965g/gm cs timestamp increment. The CLKCFG memory clock values seem less consistent but we don't care about those here.

Looks like elk redefines some of the CLKCFG FSB values to make room for 400 MHz FSB. The setting overlaps with one of the 266MHz settings (which is even documented in the ctg docs, and cofirmed to be correct on my ctg). So we limit the special case to elk only. Though it might also be that we have some kind of desktop vs. mobile difference going on here as eg. both g35 and elk use 0x0 for the 266 MHz setting, vs. 0x6 used by ctg). The g35 doesn't let me select 400MHz for the FSB strap so can't confirm which way it would go here. But anyways as it seems only elk has the 400MHz option we shouldn't lose anything by limiting the special case to it alone. My earlier experiments on this appear to have been nonsense as the comment I added claims that FSB strap of 400MHz results in a value of 0x4, but I've now retested it and I definitely get a value of 0x6 instead. So let's remove that bogus comment. v2: s/_ELK/_ALT/ in the define in anticipation of a full mobile vs. desktop CLKCFG split Signed-off-by: NVille Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200514123838.3017-1-ville.syrjala@linux.intel.comAcked-by: NChris Wilson <chris@chris-wilson.co.uk>

If we find ourselves waiting on a MI_SEMAPHORE_WAIT, either within the user batch or in our own preamble, the engine raises a GT_WAIT_ON_SEMAPHORE interrupt. We can unmask that interrupt and so respond to a semaphore wait by yielding the timeslice, if we have another context to yield to! The only real complication is that the interrupt is only generated for the start of the semaphore wait, and is asynchronous to our process_csb() -- that is, we may not have registered the timeslice before we see the interrupt. To ensure we don't miss a potential semaphore blocking forward progress (e.g. selftests/live_timeslice_preempt) we mark the interrupt and apply it to the next timeslice regardless of whether it was active at the time. v2: We use semaphores in preempt-to-busy, within the timeslicing implementation itself! Ergo, when we do insert a preemption due to an expired timeslice, the new context may start with the missed semaphore flagged by the retired context and be yielded, ad infinitum. To avoid this, read the context id at the time of the semaphore interrupt and only yield if that context is still active.

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: NImre Deak <imre.deak@intel.com> Signed-off-by: NJosé Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200414194956.164323-6-jose.souza@intel.com

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: NImre Deak <imre.deak@intel.com> Signed-off-by: NJosé Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200414194956.164323-4-jose.souza@intel.com

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.

If we find ourselves waiting on a MI_SEMAPHORE_WAIT, either within the user batch or in our own preamble, the engine raises a GT_WAIT_ON_SEMAPHORE interrupt. We can unmask that interrupt and so respond to a semaphore wait by yielding the timeslice, if we have another context to yield to! The only real complication is that the interrupt is only generated for the start of the semaphore wait, and is asynchronous to our process_csb() -- that is, we may not have registered the timeslice before we see the interrupt. To ensure we don't miss a potential semaphore blocking forward progress (e.g. selftests/live_timeslice_preempt) we mark the interrupt and apply it to the next timeslice regardless of whether it was active at the time. v2: We use semaphores in preempt-to-busy, within the timeslicing implementation itself! Ergo, when we do insert a preemption due to an expired timeslice, the new context may start with the missed semaphore flagged by the retired context and be yielded, ad infinitum. To avoid this, read the context id at the time of the semaphore interrupt and only yield if that context is still active.

Transcoder port sync was introduced to the hardware in BDW. We can trivially enable it for SKL+ since the same codepaths are already used for ICL+ port sync. The only difference is the actual location of the bits we need to poke. We leave BDW out (at least for now) since it uses different modeset paths that haven't been adapted for port sync, and IIRC using the feature would involve some extra workarounds we've not implemented. Pre-BDW hardware does not support port sync so we'd have to tweak the modeset sequence to start the pipes as close together as possible and hope for the best. So far no one has seriously tried to implement that.
