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:

This patch avoid the warning in vkms_get_vblank_timestamp when vblanks aren't enabled. When running igt test kms_cursor_crc just after vkms module, the warning raised like below. Initial value of vblank time is zero and hrtimer.node.expires is also zero if vblank aren't enabled before. vkms module isn't real hardware but just virtual hardware module. so vkms can't generate a resonable timestamp when hrtimer is off. it's best to grab the current time.

The VKMS blend function was ignoring the alpha channel and just overwriting vaddr_src with vaddr_dst. This XRGB approach triggers a warning when running the kms_cursor_crc/cursor-alpha-transparent test case. In IGT, cairo_format_argb32 uses premultiplied alpha (according to documentation). Also current DRM assumption is that alpha is premultiplied. Therefore, this patch considers premultiplied alpha blending eq to compose vaddr_src with vaddr_dst. This change removes the following cursor-alpha-transparent warning: "Suspicious CRC: All values are 0." V2: - static for local functions - const for the read-only variable argb_src - replaces variable names - drops unnecessary comment Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Rodrigo Siqueira <rodrigosiqueiramelo@gmail.com> Cc: Haneen Mohammed <hamohammed.sa@gmail.com> Signed-off-by:

The LVDS controller can invert the polarity / lanes of the LVDS output. The default polarity causes some issues on some panels. However, U-Boot has always used the opposite polarity without any reported issue, and the only currently supported LVDS panel in-tree (the TBS A711) seems to be able to work with both settings. Let's just use the same polarity than U-Boot to be more consistent and hopefully support all the panels. Signed-off-by:

This patch implements WA for AM65xx erratum i2000, which causes YUV formats to show wrong colors. An earlier patch removed a partial WA: a8d9d7da ("drm/tidss: remove AM65x PG1 YUV erratum code") The patch explains the reasoning for removal. The change in plans has been that it has become clear that there are and will be users for PG1 SoCs and as such it's good to implement the WA for PG1s. This patch adds the WA back so that it is only used on SR1.0 (which is the new name for PG1). The previous WA code didn't check the SoC revision, which this patch does. Signed-off-by:
