The HVS found in the BCM2711 has 6 outputs and 3 FIFOs, with each output being connected to a pixelvalve, and some muxing between the FIFOs and outputs. Any output cannot feed from any FIFO though, and they all have a bunch of constraints. In order to support this, let's store the possible FIFOs each output can be assigned to in the vc4_crtc_data, and use that information at atomic_check time to iterate over all the CRTCs enabled and assign them FIFOs. The channel assigned is then set in the vc4_crtc_state so that the rest of the driver can use it. Signed-off-by:

The vc4 atomic commit loop has an handrolled loop that is basically identical to for_each_new_crtc_state, let's convert it to that helper. Signed-off-by:

The VIDEN bit in the pixelvalve currently being used to enable or disable the pixelvalve seems to not be enough in some situations, which whill end up with the pixelvalve stalling. In such a case, even re-enabling VIDEN doesn't bring it back and we need to clear the FIFO. This can only be done if the pixelvalve is disabled though. In order to overcome this, we can configure the pixelvalve during mode_set_no_fb by calling vc4_crtc_config_pv, but only enable it in atomic_enable and flush the FIFO there, and in atomic_disable disable the pixelvalve again.

In vc5, the HVS has 6 outputs and 3 FIFOs (or channels), with pixelvalves each being assigned to a given output, but each output can then be muxed to feed from multiple FIFOs. Since vc4 had that entirely static, both were probably equivalent, but since that changes, let's rename hvs_channel to hvs_output in the vc4_crtc_data, since a pixelvalve is really connected to an output, and not to a FIFO.

The COB allocation depends on the HVS channel used for a given pixelvalve. While the channel allocation was entirely static in vc4, vc5 changes that and at bind time, a pixelvalve can be assigned to multiple HVS channels. Let's prepare that rework by allocating the COB when it's actually needed. Signed-off-by:

Let's now create more planes that can be affected to all the CRTCs. vc4 has 3 CRTCs, 1 primary and 1 cursor each, and was having 24 (8 planes per CRTC) overlays. However, vc5 has 5 CRTCs, so keeping the same logic would put us at 50 planes which is well above the 32 planes limit imposed by DRM. Using 16 seems like a good tradeoff between staying under 32 and yet providing enough planes. Signed-off-by:

The current code is using the maximum of the source line size and the destination line size to compute the size of the LBM to allocate. While this is simpler, it starts to be an issue with modes such as 4k with a quite long that will consume all the available memory, so we no longer have that luxury. Signed-off-by:

Current code does not properly computes the max length of LP commands that can be send during H or V sync, and rely on static values.

The upstream S6E63M0 driver has some peculiarities around the prepare/enable disable/unprepare sequence: the screen is taken out of sleep in prepare() as part of s6e63m0_init() the put to on with MIPI_DCS_SET_DISPLAY_ON in enable(). However it is just put into sleep mode directly in disable(). As disable()/enable() can be called without unprepare()/prepare() being called, this is unbalanced, we should take the display out of sleep in enable() then turn it off(). Further MIPI_DCS_SET_DISPLAY_OFF is never called balanced with MIPI_DCS_SET_DISPLAY_ON. The vendor driver for Samsung GT-I8190 (Golden) does all of these things in strict order. Augment the driver to do exit sleep/set display on in enable() and set display off/enter sleep in disable(). Further send an explicit reset pulse in power_on() so we come up in a known state, and issue the MCS_ERROR_CHECK command after setting display on like the vendor driver does. Also use the timings from the vendor driver in the sequence. Doing all of these things makes the display much more stable on the Samsung GT-I8190 when enabling/disabling the display pipeline.

This panel can be accessed using both SPI and DSI. To make it possible to probe and use the device also from a DSI bus, first break out the SPI support to its own file. Since all the panel driver does is write DCS commands to the panel, we pass a DCS write function to probe() from each subdriver. We make the Kconfig entry for SPI mode default so all current users will continue to work. Signed-off-by:

Following functions are only used internally, not by drivers: - devm_drm_dev_init Also, now that we have a very slick and polished way to allocate a drm_device with devm_drm_dev_alloc, update all the docs to reflect the new reality. Mostly this consists of deleting old and misleading hints. Two main ones: - it is no longer required that the drm_device base class is first in the structure. devm_drm_dev_alloc can cope with it being anywhere - obviously embedded now strongly recommends using devm_drm_dev_alloc v2: Fix typos (Noralf) v3: Split out the removal of drm_dev_init, that's blocked on some discussions on how to convert vgem/vkms/i915-selftests.

While working on TTM cleanups I've found that the io_reserve_lru used by Nouveau is actually not working at all. In general we should remove driver specific handling from the memory management, so this patch moves the io_reserve_lru handling into Nouveau instead. v2: don't call ttm_bo_unmap_virtual in nouveau_ttm_io_mem_reserve v3: rebased and use both base and offset in the check v4: fix small typos and test the patch v5: rebased and keep the mem.bus init in TTM.

In order to shrink drm_display_mode below the magic two cacheline mark in 64bit we need to shrink it by another 8 bytes. The easiest thing to eliminate is the 'export_head' list head which is only used during the getconnector ioctl to temporarly track which modes on the connector's mode list are to be exposed and which are to remain hidden. We can simply replace the list head with a boolean which we use to tag the modes that are to be exposed. If we make sure to clear the tags after we're done with them we don't even need an extra loop over the modes to reset the tags at the start of the getconnector ioctl. Conveniently we already have a hole for the boolean left behind by the removal of mode->private_flags. The final size of the struct is now 112 bytes on 32bit and 120 bytes on 64bit. Another alternative would be a temp bitmask so we wouldn't have to have anything in the mode struct itself. The main issue is how large of a bitmask do we need? I guess we could allocate it dynamically but that means an extra kcalloc() and an extra loop through the modes to count them first (or grow the bitmask with krealloc() as needed).

For DP MST outputs, the i2c device currently only supports transfers that can be implemented using remote i2c reads. Such transfers must consist of zero or more write transactions followed by one read transaction. DDC/CI commands require standalone write transactions and hence aren't supported. Since each remote i2c write is handled as a separate transfer, remote i2c writes can support transfers consisting of write transactions, where all but the last have I2C_M_STOP set. According to the DDC/CI 1.1 standard, DDC/CI commands only require a single write or read transaction in a transfer, so this is sufficient. For i2c transfers meeting the above criteria, generate and send a remote i2c write message for each transaction. Add the trivial remote i2c write reply parsing support so remote i2c write acks bubble up correctly. Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/37Signed-off-by:
