Even though PW#1 and the MISC_IO power wells are managed by the DMC firmware (toggled dynamically if conditions allow it) from the driver's POV they are always on if the display core is initialized (always restored by DMC to the enabled state after exiting from DC5/6 for instance b/c of MMIO access). Accordingly we can just mark them as always-on and remove the special casing for them during state verification (thus enabling verification for these power wells too).

A DMC bug on GEN9 big core machines fails to restore the driver's request bits for the PW1 and MISC_IO power wells after a DC5/6 entry->exit sequence. As a consequence the driver's subsequent check for the enabled status of these power wells will fail, as the check considers the power wells being enabled only if both the status and request bits are set. To work around this borrow the request bits from BIOS's own request register in which DMC forces on the request bits when exiting from DC5/6. This fixes a problem reported by Ramalingam, where HDCP init failed, since PW1 reported itself as being disabled, while in reality it was enabled. Reported-by:

I think I'm probably the one who argued in favor of having separate implementations for both PCHs, but the calculations are actually the same, the clocks are the same and the only difference is that on ICP we write the numerator to the register. I have previously suggested to kill cnp_rawclk() and keep the icp_rawclk() style, but Ville gave some good arguments that what's in this patch may be the better choice. v2: Switch numerator to 1 from 1000 and adjust calculations accordingly (Ville).

Although CNP names this field "Counter Fraction", what we write to the register is really the denominator for the fractional part of the divider, not the fractional part (and the field description even says that). The ICP spec renamed the field to "Counter Fraction Denominator", which makes a lot more sense. Use the more complete ICL naming because we will merge the CNP and ICP functions into a single one, which will introduce the concept of the numerator. That will make a lot more sense when you read the "num/frac = den" calculation. Reviewed-by:

VBT appears to have two (or possibly three) ways to indicate the panel rotation. The first is in the MIPI config block, but that apparenly usually (maybe always?) indicates 0 degrees despite the actual panel orientation. The second way to indicate this is in the general features block, which can just indicate whether 180 degress rotation is used. The third might be a separate rotation data block, but that is not at all documented so who knows what it may contain. Let's try the first two. We first try the DSI specicic VBT information, and it it doesn't look trustworthy (ie. indicates 0 degrees) we fall back to the 180 degree thing. Just to avoid too many changes in one go we shall also keep the hardware readout path for now. If this works for more than just my VLV FFRD the question becomes how many of the panel orientation quirks are now redundant? v2: Move the code into intel_dsi.c (Jani) Cc: Hans de Goede <hdegoede@redhat.com> Reviewed-by:

Let's make sure the DSI port is actually on before we go poking at the plane register to determine which way it's rotated. Otherwise we could be looking at a plane that is feeding a HDMI port for instance. And in order to read the plane register we need the power well to be on. Make sure that is indeed the case. We'll also make sure the plane is actually enabled before we trust the rotation bit to tell us the truth. v2: s/intel_dsi/vlv_dsi/ Cc: Hans de Goede <hdegoede@redhat.com> Signed-off-by:

Reduce the clutter in the sprite update functions by writing both TILEOFF and LINOFF registers unconditionally. We already did this for primary planes so might as well do it for the sprites too. There is no harm in writing both registers. Which one gets used depends on the tilimg mode selected in the plane control registers. It might even make sense to clear the register that won't get used. That could make register dumps a little easier to parse. But I'm not sure it's worth the extra hassle. Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by:

We no longer change LSPCON into PCON mode if it boots up in LS mode. This was broken by some code shuffling in commit 96e35598 ("drm/i915: Check LSPCON vendor OUI"). I actually can't see a reason why that code shuffling had to be done. The commit msg notes it but doesn't justify it in any way. But I guess we'll keep the code in its current place anyway and just make the "switch to PCON mode" part effective once again.

IBX has a documented workaround which states that when we disable the port we must change its transcoder select to A, otherwise it will prevent the other port (DP vs. HDMI/SDVO) from using transcoder A. We implement the workaround during encoder disable, but looks like some BIOSen leave transcoder B selected even when the port wasn't actually enabled by the BIOS. That will trip up our asserts that attempt to make sure we never forget this w/a. Sanitize the transcoder select to A for all disabled PCH DP/HDMI/SDVO ports. We assume that the port was never enabled by the BIOS on transcoder B, because if it had we'd actually have to toggle the port on and back off to properly switch it back to transcoder A. That would cause some display flicker if transcoder A is already enabled on some other port, so it's better not to do it unless absolutely necessary. Since we have no indication that the transcoder select is misbehaving on the affected machines we can assume the port was never actually enabled by the BIOS. This cures warning like this during driver load: IBX PCH DP C still using transcoder B WARNING: CPU: 2 PID: 172 at drivers/gpu/drm/i915/intel_display.c:1279 assert_pch_dp_disabled+0x9e/0xb0 [i915] v2: Add comments to remind the reader that SDVOB==HDMIB (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by:
