The kernel prefers enabling fbc over the initial fb, since this leads to actual runtime power savings, so if the initial fb is deemed too big using some heuristic, then we simply skip allocating stolen for it. However if the kernel is not configured with fbcon then it should be possible to relax this, since unlike with fbcon the display server shouldn't preserve it when later replacing it, and so we should be able to re-use the stolen memory for fbc and friends. This patch is reported to fix some flicker seen during boot splash on some devices. v2: s/FRAMEBUFFER_CONSOLE/CONFIG_FRAMEBUFFER_CONSOLE Signed-off-by:

XE_LPD brings enhanced underrun recovery: the hardware can somewhat mitigate underruns by using an interpolated replacement pixel (soft underrun) or the previous pixel (hard underrun). Furthermore, underruns can now be caused downstream by the port, even if the pipe itself is operating properly. The interrupt register and PIPE_STATUS register give us extra bits to recognize hard/soft underruns and determine whether the underrun was caused by the port, so we'll use that information to print some more descriptive errors when underruns occur. v2: - Keep ICL's PIPE_STATUS defined separately from the old GMCH pipe status register. (Ville) - Only read/clear the PIPE_STATUS register on platforms with display ver >= 11. (Lucas) v3: - Actually enable+unmask all the new underrun interrupts, clear stale bits out from PIPE_STATUS before enabling the interrupts, report all FIFO underruns errors at once, rename a bunch of stuff to unconfuse vs. PIPESTAT.

All DPT FB color plane surface base addresses must be 2MB aligned. On ADL_P this means that the offsets in CCS FB object must be also 2MB aligned. Adjusting unaligned offsets for these FBs during commit time (compensating with the x/y offsets) doesn't work, since the big alignment would most probably lead to an x/y offset mismatch error between the main and CCS planes. We can overcome this limitation by remapping CCS FBs, so that each color plane is at an aligned offset, leaving x/y for each plane unadjusted during commit and so not causing an x/y mismatch error. However remapping for CCS FBs will be done as a follow-up, so for now require that user space allocates the FB obj with properly aligned planes. v2: s/SZ_2M/512*4k/ for clarity.

The driver currently disables the LTTPR non-transparent link training mode for sinks with a DPCD_REV<1.4, based on the following description of the LTTPR DPCD register range in DP standard 2.0 (at the 0xF0000 register description): "" LTTPR-related registers at DPCD Addresses F0000h through F02FFh are valid only for DPCD r1.4 (or higher). """ The transparent link training mode should still work fine, however the implementation for this in some retimer FWs seems to be broken, see the References: link below. After discussions with DP standard authors the above "DPCD r1.4" does not refer to the DPCD revision (stored in the DPCD_REV reg at 0x00000), rather to the "LTTPR field data structure revision" stored in the 0xF0000 reg. An update request has been filed at vesa.org (see wg/Link/documentComment/3746) for the upcoming v2.1 specification to clarify the above description along the following lines: """ LTTPR-related registers at DPCD Addresses F0000h through F02FFh are valid only for LT_TUNABLE_PHY_REPEATER_FIELD_DATA_STRUCTURE_REV 1.4 (or higher) """ Based on my tests Windows uses the non-transparent link training mode for DPCD_REV==1.2 sinks as well (so presumably for all DPCD_REVs), and forcing it to use transparent mode on ICL/TGL platforms leads to the same LT failure as reported at the References: link. Based on the above let's assume that the transparent link training mode is not well tested/supported and align the code to the correct interpretation of what the r1.4 version refers to.

Today when the DSI controller is paired with the Combo-PHY it uses the high-speed (HS) Word clock for its low power (LP) transmit PPI communication to the DPHY. The interface signaling only changes state at an Escape clock frequency (i.e. its effectively running on a virtual Tx Escape clock that is controlled by counters w/in the controller), but all the interface flops are running off the HS clock. This has the following drawbacks: * It is a deviation from the PPI spec which assumes signaling is running on a physical Escape clock * The PV timings are over constrained (HS timed to 312.5MHz vs. an Escape clock of 20MHz max) This feature is proposing to change the LP Tx communication between the controller and the DPHY from a virtual Tx Escape clock to a physical clock. To do this we need to program two "M" divisors. One for the usual DSI_ESC_CLK_DIV and DPHY_ESC_CLK_DIV register and one for MIPIO_DWORD8. For DSI_ESC_CLK_DIV and DPHY_ESC_CLK_DIV registers the "M" is calculated as following Nt = ceil(f_link/160) (theoretical word clock) Nact = max[3, Nt + (Nt + 1)%2] (actual word clock) M = Nact * 8 For MIPIO_DWORD8 register, the divisor "M" is calculated as following M = (Nact - 1)/2 BSpec: 55171 Cc: Vandita Kulkarni <vandita.kulkarni@intel.com> Signed-off-by:
