This tiling layout uses 4KB tiles in a row-major layout. It has the same shape as Tile Y at two granularities: 4KB (128B x 32) and 64B (16B x 4). It only differs from Tile Y at the 256B granularity in between. At this granularity, Tile Y has a shape of 16B x 32 rows, but this tiling has a shape of 64B x 8 rows. Reviewed-by:

Currently we just leave the old gunk lying around in the crtc state when userspace asks us to fully disable the crtc. That doesn't match what the state would be had we never even enabled the crtc in the first place. So let's make this consistent and call intel_crtc_prepare_cleared_state() for disabled crtcs as well (excluding bigjoiner slaves of course which have had their state copied from the master). I actually already did this once in commit fff13e63 ("drm/i915: Clear most of crtc state when disabling the crtc") but then commit 19f65a3d ("drm/i915: Try to make bigjoiner work in atomic check") undid it all :( Signed-off-by:

For some reason we're flagging that we need to run through the full modeset calculations (any_ms==true -> do cdclk/etc. checks) if any crtc got initially flagged for a modeset and is not enabled via the uapi. No idea why this is here since later on (after all fastset handling) we do full run through the crtcs and flag any_ms if anything still needs a full modeset. So let's just throw out this early weirdo. Signed-off-by:

With some VRR panels, user can turn VRR ON/OFF on the fly from the panel settings. When VRR is turned OFF ,sends a long HPD to the driver clearing the Ignore MSA bit in the DPCD. Currently the driver parses that onevery HPD but fails to reset the corresponding VRR Capable Connector property. Hence the userspace still sees this as VRR Capable panel which is incorrect. Fix this by explicitly resetting the connector property. v2: Reset vrr capable if status == connector_disconnected v3: Use i915 and use bool vrr_capable (Jani Nikula) v4: Move vrr_capable to after update modes call (Jani N) Remove the redundant comment (Jan N) Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by:

The VBT DSI video transfer mode field values have been defined in terms of the VLV MIPI_VIDEO_MODE_FORMAT register. The ICL DSI code maps that to ICL DSI_TRANS_FUNC_CONF() register. The values are the same, though the shift is different. Make a clean break and disassociate the values from each other. Assume the values can be different, and translate the VBT value to VLV and ICL register values as needed. Use the existing macros from intel_bios.h. This will be useful in splitting the DSI register macros to files by DSI implementation. Cc: Matt Roper <matthew.d.roper@intel.com> Reviewed-by:

First the simplest ones: - iosys_map_memset(): when abstracting system and I/O memory, just like the memcpy() use case, memset() also has dedicated functions to be called for using IO memory. - iosys_map_memcpy_from(): we may need to copy data from I/O memory, not only to. In certain situations it's useful to be able to read or write to an offset that is calculated by having the memory layout given by a struct declaration. Usually we are going to read/write a u8, u16, u32 or u64. As a pre-requisite for the implementation, add iosys_map_memcpy_from() to be the equivalent of iosys_map_memcpy_to(), but in the other direction. Then add 2 pairs of macros: - iosys_map_rd() / iosys_map_wr() - iosys_map_rd_field() / iosys_map_wr_field() The first pair takes the C-type and offset to read/write. The second pair uses a struct describing the layout of the mapping in order to calculate the offset and size being read/written. We could use readb, readw, readl, readq and the write* counterparts, however due to alignment issues this may not work on all architectures. If alignment needs to be checked to call the right function, it's not possible to decide at compile-time which function to call: so just leave the decision to the memcpy function that will do exactly that. Finally, in order to use the above macros with a map derived from another, add another initializer: IOSYS_MAP_INIT_OFFSET(). v2: - Rework IOSYS_MAP_INIT_OFFSET() so it doesn't rely on aliasing rules within the union - Add offset to both iosys_map_rd_field() and iosys_map_wr_field() to allow the struct itself to be at an offset from the mapping - Add documentation to iosys_map_rd_field() with example and expected memory layout v3: - Drop kernel.h include as it's not needed anymore Cc: Sumit Semwal <sumit.semwal@linaro.org> Cc: Christian König <christian.koenig@amd.com> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Mauro Carvalho Chehab <mchehab@kernel.org> Cc: dri-devel@lists.freedesktop.org Cc: linux-kernel@vger.kernel.org Signed-off-by:Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by:

DG2 supports a 5th display output which the hardware refers to as "TC1," even though it isn't a Type-C output. This behaves similarly to the TC1 on past platforms with just a couple minor differences: * DG2's TC1 bit in SDEISR is at bit 25 rather than 24 as it is on ICP/TGP/ADP. * DG2 doesn't need the hpd inversion setting that we had to use on DG1 v2: intel_ddi_init(dev_priv, PORT_TC1); [Matt] Cc: Swathi Dhanavanthri <swathi.dhanavanthri@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by:

Currently ICL_PHY_MISC macro is returning offset 0x64C10 for PHY_E. The PORT_TC1 port is not yet enabled properly in the driver, but intel_phy_snps.c is relying on intel_phy_is_snps() to filter out unavailable phys. That function was already considering the last phy as available. Just correct the offset of the last phy to 0x64C14 as the rest of the support for it is coming on next commits. Signed-off-by:

Ville Syrjälä authored
If the only thing that is changing is SAGV vs. no SAGV but the number of active planes and the total data rates end up unchanged we currently bail out of intel_bw_atomic_check() early and forget to actually compute the new WGV point mask and thus won't actually enable/disable SAGV as requested. This ends up poorly if we end up running with SAGV enabled when we shouldn't. Usually ends up in underruns. To fix this let's go through the QGV point mask computation if either the data rates/number of planes, or the state of SAGV is changing. v2: Check more carefully if things are changing to avoid the extra calculations/debugs from introducing unwanted overhead Cc: stable@vger.kernel.org Reviewed-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> #v1 Fixes: 20f505f2 ("drm/i915: Restrict qgv points which don't have enough bandwidth.")

When changing between SAGV vs. no SAGV on tgl+ we have to update the use_sagv_wm flag for all the crtcs or else an active pipe not already in the state will end up using the wrong watermarks.

We don't want any RMWs in the part of the commit that happens under vblank evasion. Eventually we want to use the DSB to handle that and it can't read registers at all. Also reads are just slowing us down needlessly. Let's move the whole PIPE_CHICKEN stuff out from the critical section since we don't have anything there that needs to be syncrhonized with other plane/pipe registers. If we ever need to add such things then we have to move it back, but without doing any reads. TODO: should look into eliminating the RMW anyway... Signed-off-by:

BIOS may leave a TypeC PHY in a connected state even though the corresponding port is disabled. This will prevent any hotplug events from being signalled (after the monitor deasserts and then reasserts its HPD) until the PHY is disconnected and so the driver will not detect a connected sink. Rebooting with the PHY in the connected state also results in a system hang. Fix the above by disconnecting TypeC PHYs on disabled ports. Before commit 64851a32 the PHY connected state was read out even for disabled ports and later the PHY got disconnected as a side effect of a tc_port_lock/unlock() sequence (during connector probing), hence recovering the port's hotplug functionality.
