The BCM2835 I2C blocks have a register to set the clock-stretch timeout - how long the device is allowed to hold SCL low - in bus cycles. The current driver doesn't write to the register, therefore the default value of 64 cycles is being used for all devices. Set the timeout to the value recommended for SMBus - 35ms.

Seen on a VLI VL805 PCIe to USB controller. For non-stream endpoints at least, if the xHC halts on a particular TRB due to an error then the DCS field in the Out Endpoint Context maintained by the hardware is not updated with the current cycle state. Using the quirk XHCI_EP_CTX_BROKEN_DCS and instead fetch the DCS bit from the TRB that the xHC stopped on.

An upstream commit to report HVS underruns causes VC4 in firmware KMS mode to cross into the HVS side, where it crashes due to a NULL hvs pointer. Make the underrun masking conditional on the hvs pointer being initialised. Fixes: 531a1b62 ("drm/vc4: Report HVS underrun errors") Signed-off-by: Phil Elwell <phil@raspberrypi.org>

Incorrect masking was used in the switch for the modifier, therefore for SAND (which puts the column pitch in the modifier) it didn't match. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>

Previously multiple displays were slaved off the same SMI interrupt, triggered by HVS channel 1 (HDMI0). This doesn't work if you only have a DPI or DSI screen (HVS channel 0), and gives slightly erroneous results with dual HDMI as the events for HDMI1 are incorrect. Use SMIDSW0 and SMIDSW1 registers to denote which display has triggered the vblank. Handling should be backwards compatible with older firmware.

The max resolution had been increased from 2048 to 7680 for all platforms. This code is common with Pi0-3 which have a max render target for GL of 2048, therefore the increased resolution has to be conditional on the platform. Switch based on whether the bcm2835-v3d node is found, as that is not present on Pi4. (There is a potential configuration on Pi0-3 with no v3d, but this is very unlikely).

The VPU has configured clocks for 4k (or not) via config.txt, and will limit the choice of video modes based on that. Make fkms query it for these limits too to avoid selecting modes that can not be handled by the current clock setup. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>

It's reasonable for the firmware to return zero as the number of attached displays. Handle this case as otherwise drm thinks that the DSI panel is attached, which is nonsense. Signed-off-by: Jonathan Bell <jonathan@raspberrypi.org>

For DPI and DSI displays query the firmware as to the configuration and add it as the only mode for DRM. In theory we can add plumbing for setting the DPI/DSI mode from KMS, but this is not being added at present as the support frameworks aren't present in the firmware.

The overscan support was required for the old mailbox API in order to match up the cursor and frame buffer planes. With the newer API directly talking to dispmanx there is no difference, therefore FKMS does not need to make any adjustments. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>

This uses a new API that is exposed via the mailbox service to stick an element straight on the screen using DispmanX.

The core doesn't expect a false return from the scanoutpos function in normal usage, so we were doing the precise vblank timestamping path and thus "immediate" vblank disables (even though firmwarekms can't actually disable vblanks interrupts, sigh), and the kernel would get confused when getting timestamp info when also turning vblanks back on.

This should technically not expose VC4_T_TILED on pi4. However, if we don't expose anything, then userspace will assume that display can handle whatever modifiers 3d can do (UIF on 2711). By exposing a list, that will get intersected with what 3D can do so that we get T tiling for display on 2710 and linear on 2711. Signed-off-by: Eric Anholt <eric@anholt.net>
