[why] 'Divide by zero' error happens when line size happens to be zero. [how] The code that makes sure line size minimum value can be 1 was already present in DCN1 part of the driver, this is mearly a port to DCN2. Signed-off-by:

[Why] In order to ensure that incoming flips are latched and complete immediately, we need to program the vupdate interrupt to come during the back porch of each frame. [How] Program the vupdate start_line to be in the back porch like it's done for DCN1. Signed-off-by:

Different HW will need to init HUBP differently. For now, add a vtable entry, and hook a NO-OP for DCN1 and DCN2. In addition, future HW will need to access the HUBPREQ_DEBUG and CUR_TTU_CNTL0 register for hubp_init. Add that here. Signed-off-by:

[Why] Due to the generic introduction of seamless boot, the display is no longer blanked upon boot. However, this causes corruption on some systems that does not lock the memory in the non-secure boot case, resulting in brief corruption on boot due to garbage being written into the frame buffer. [How] Add a flag, read during DC init, to determine whether display should be blanked on boot. Default to true. Signed-off-by:

[why] The current policy will always enable DSC to 12 bpp regardless of if the current bandwidth is enough for MST displays. This logic is not optimal because user will get lower quality output if DSC compression is enabled. This change to is to implement a DSC MST bandwidth fair share algorithm so we will dynamically decide if DSC is needed and what quality (target bpp) is needed to fairly destribute the MST bandwidth in one MST topology. This will allow user to see the most optimal image quality with the given bandwidth. [how] We will start with lowest bandwidth possible and run a Max-Min fairness algorithm to fairly distribute the available bandwidth. If there is still remaining bandwidth, we will try to fit the timing without DSC compression. Signed-off-by:

[why] when an update programming sequence requires both front end and back end pipe to be updated synchronously, a global update lock needs to be set to ensure that we don't get a frame with only front end update but not the back end update.

We can split validation into three parts: getting voltage level, getting watermarks, and rq/dlg calculations. The voltage level is enough to answer the question "do we support this state", and the rest of it is to determine what hardware programming is needed to support the state. Most of the calls to validate_bandwidth only care about the first part, so we added an early return in that case Signed-off-by:

[Why] display_mode_vba is for DCN2 and up. When building for upstream (DCN1 enabled only), there will be a build error, since display_mode_vba.c/h is stripped out. Note that building DCN1 only with internal dal-dev is still fine, since display_mode_vba.h is not stripped out internally - only in upstream. The make directives therefore stll work, and so will any #include's. [How] Since subsequent generations require DCN2 enabled anyways, guard the makefile directive for display_mode_vba.o with DCN2. Guard any includes with DCN2. In addition, guard the entire contents of display_mode_vba.h with DCN2, to simulate the file being stripped out in upstream. A forward declaration for 'struct display_mode_lib' also needs to be added in display_mode_lib.h. Previously, display_mode_vba.h contained the forward declaration, and display_mode_lib.h in turn included it. This won't work if mode_vba.h is stripped out, requring mode_lib.h to do so itself.

[why] On at least some of the devices (e.g. Realtek scaler) we get a black screen if 1/16th precision is used. [how] Work around it by reducing precision to 1/8th for N4:2:2 and 4:2:0 color formats. This is a safe workaround and would have a very mild impact on the quality. The issue is still to be root-caused and fixed correctly. Signed-off-by:

In this case when we get down to dcn20_setup_gsl_group_as_lock, pipe_ctx->plane_state is NULL, but we don't check for it. However, this function is only called by dcn20_pipe_control_lock, and in that function we alraedy have a local for the immediate flip status, which is what we care about in the plane state.
