Otherwise dp aux won't work on some hsw platforms, since they use a different rawclk than the 125MHz clock used thus far. To absolutely not change anything, round up: That way we get the old 63 divider for the default 125MHz clock. Reviewed-by:

We need this when the bios forgets even to set that bit up. Most seem to do that, even when they don't set up anything else in the panel power sequencer. Note that on IBX the rawclk is variable according to Bspec, but everyone is using 125MHz. The rawclk is fixed to 125MHz on CPT, but luckily we still have the same register available. On hsw, different variants have different clocks, hence we need to check the register. Since other pieces are driven by the rawclock, too, keep the little helper in a central place. Reviewed-by:

Like we already do for the LVDS panels. This seems to help greatly in setting up the backlight, since the BIOS might refuse to cooperate. Reviewed-by:

3 changes: - If a given value is unset, use the maximal limits from the eDP spec. - Write back the new values, since otherwise the panel power sequencing hw will not dtrt. - Revert the early bail-out in case the register values are unset. The last change reverts commit bfa3384a Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Tue Apr 10 11:58:04 2012 -0700 drm/i915: check PPS regs for sanity when using eDP v2: - Unlock the PP regs as the very first thing. This is a required w/a for cpu eDP on port A, and generally a good idea. - Fixup the panel power control port selection bits. v3: Paulo Zanoni noticed that I've fumbled the computation of the spec limit values. Fix them up. We've also noticed that the t8/t9 values in the vbt/bios-programmed pp are much larger than any limits. My guess is that this is to conceal any backlight enable/disable delays. So by using the much shorter limits from the spec, which only concerns the sink, we risk that we might display before the backlight is fully on, or disable the output while the backlight still has afterglow. I've figured I don't care too much, since this will only happen when both the pp regs are not programmed, and the vbt tables don't contain anything useful. v4: Don't set the port selection bits on hsw/LPT, they don't exist any more. v5: Fixup spelling issues in comments, as noticed by Jesse Barnes.

Only really required for dp 1.2. I've hoped this would help with some link training woes I'm fighting, but alas those are only dp 1.1 devices. Also move a comment that went misplaced in the recent refactorings to the right spot again. Reviewed-by:

This requires a few changes since that dpcd value is above the range currently cached by radeon. I've check the dp specs, and above 0xf there's a big gap and nothing that looks like we should cache it while a given device is plugged in. It's also the same value that i915.ko uses. Hence extend the various dpcd arrays in the radeon driver, use proper symbolic constants where applicable (one place overallocated the dpcd array to 25 bytes). Then also drop the rd_interval cache - radeon_dp_link_train_init re-reads the dpcd block, so the values we'll consume in train_cr and train_ce will always be fresh. To avoid needless diff-churn, #define the old size of dpcd as the new one and keep it around. v2: Alex Deucher noticed one place where I've forgotten to replace 8 with DP_RECEIVER_CAP_SIZE.

Create a generic struct intel_panel for sharing a data structure and code between eDP and LVDS panels. Add the new struct to intel_connector so that later on we can have generic EDID and mode reading functions with EDID caching that transparently fallback to fixed mode when EDID is not available. Add intel_panel as a dummy first, and move data (such as the mentioned fixed mode) to it in later patches.

As there is 1:1 mapping between encoder and connector for the LVDS, the goal is to simply reduce the amount of noise within the connector functions, i.e. we split the encoder/connector for LVDS as best we can and try to only operate on the LVDS connector from the connector funcs and the LVDS encoder form the encoder funcs.

Linux 3.7-rc2 Backmerge to solve two ugly conflicts: - uapi. We've already added new ioctl definitions for -next. Do I need to say more? - wc support gtt ptes. We've had to revert this for snb+ for 3.7 and also fix a few other things in the code. Now we know how to make it work on snb+, but to avoid losing the other fixes do the backmerge first before re-enabling wc gtt ptes on snb+. And a few other minor things, among them git getting confused in intel_dp.c and seemingly causing a conflict out of nothing ...

An interesting effect of using the generic version of linkage.h is that the padding is defined in terms of x86 NOPs, which can have even more interesting effects when the assembly code looks like this: ENTRY(func1) mov x0, xzr ENDPROC(func1) // fall through ENTRY(func2) mov x0, #1 ret ENDPROC(func2) Admittedly, the code is not very nice. But having code from another architecture doesn't look completely sane either. The fix is to add arm64's version of linkage.h, which causes the insertion of proper AArch64 NOPs. Signed-off-by:

This either results in guest memory corruption and or the hardware faulting and 'crashing' the virtual machine. Therefore we have to disable PEBS on VT-x enter and re-enable on VT-x exit, enforcing a strict exclude_guest.

Emit the magic string that indicates a module has a signature after the signature data instead of before it. This allows module_sig_check() to be made simpler and faster by the elimination of the search for the magic string. Instead we just need to do a single memcmp(). This works because at the end of the signature data there is the fixed-length signature information block. This block then falls immediately prior to the magic number. From the contents of the information block, it is trivial to calculate the size of the signature data and thus the size of the actual module data. Signed-off-by:
