2014-01-24drm/i915: Shuffle modeset reset handling aroundDaniel Vetter
Currently we're doing the reset handling a bit late, and we're doing it both in the driver load code and on resume. This makes it unusable for e.g. resetting the panel power sequence state like Paulo wants to. Instead of adding yet another single-use callback shuffle things around: - Output handling code is responsible to reset/init all state on its own at driver load time. - We call the reset functions much earlier, before we start using any of the modeset code. Compared to Paulo's new ->resume callback the only difference in placement is that ->reset is still called without dev->struct_mutex held. Which is imo a feature. v2: Rebase on top of the now merge dinq.

2014-01-24drm/i915: set the backlight panel delays registers to 1Paulo Zanoni
Because we already do the wait in software: see ironlake_wait_backlight_on and ironlake_edp_wait_backlight_off. For the "backlight on" delay, even BSpec says we need to program 0x1 to PP_ON_DELAYS 12:0. For the "backlight off" delay, if we don't do the same thing, when we call ironlake_wait_panel_off we'll end up waiting for the it again. On my machine the off delay is 200ms, so we save this amount of time whenever we disable the panel (e.g, suspend).

2014-01-24drm/i915: don't wait for power cycle when waiting for power offPaulo Zanoni
Function ironlake_wait_panel_off should just wait for the power off delay, while function ironlake_wait_panel_power_cycle should wait for the panel cycle (that's required after we turn the panel off, before we enable it again). The problem is that, currently, ironlake_wait_panel_off is waiting not just for the panel to be off, but also for the power cycle delay and the backlight off delay. This function relies on the PP_STATUS bits 3:0, which are not documented and not supposed to be used. A quick analysis of the values we get while waiting quickly shows that power off is reached while bits 3:0 are still 0x1, and the time it takes to become 0x0 is the power cycle delay. On my system with backlight off delay of 200ms, power down delay of 50ms and power cycle delay of 500ms, this is what I get: - Start waiting with value 0x80000008, timestamp 6.429364. - Jumps to 0xa0000003, timestamp 6.431360 (time waited: 0.001996) - Jumps to 0xa0000002, timestamp 6.631277 (time waited: 0.201913) - Jumps to 0x08000001, timestamp 6.681258 (time waited: 0.251894) - Jumps to 0x00000000, timestamp 7.192012 (time waited: 0.762648) As you can see, ironlake_wait_panel_off is sleeping 760ms instead of the expected 50ms: the first 200ms matches the backlight off delay (which we should already have waited for!), then the 50ms for the real panel off delay, then the 500ms for the panel power cycle. This patch makes is look just at bits 31 and 29:28, which will ignore the panel power cycle. And just to be clear: this saves 500ms on my system every time we disable the panel. But we can still save 200ms more (the backlight off delay) on the next patches.

They now also work on vlv, which has the regs somewhere else. And daring a glance into the looking glass it seems like this functionality will continue to work the same for the next few hardware platforms. So it's better to just remove that misleading prefix and have a bit shorter code for better readability. The only exceptions are the panel/backlight functions shared with intel_ddi.c, those get an intel_ prefix. While at it make the vdd_on/off functions static. And one straggler was missing the edp_ in the name, so make everything neatly OCD.

2014-01-24drm/i915: save some time when waiting the eDP timingsPaulo Zanoni
The eDP spec defines some points where after you do action A, you have to wait some time before action B. The thing is that in our driver action B does not happen exactly after action A, but we still use msleep() calls directly. What this patch does is that we record the timestamp of when action A happened, then, just before action B, we look at how much time has passed and only sleep the remaining amount needed. With this change, I am able to save about 5-20ms (out of the total 200ms) of the backlight_off delay and completely skip the 1ms backlight_on delay. The 600ms vdd_off delay doesn't happen during normal usage anymore due to a previous patch. v2: - Rename ironlake_wait_jiffies_delay to intel_wait_until_after and move it to intel_display.c - Fix the msleep call: diff is in jiffies v3: - Use "tmp_jiffies" so we don't need to worry about the value of "jiffies" advancing while we're doing the math. v4: - Rename function again. - Move function to i915_drv.h. - Store last_power_cycle at edp_panel_off too. - Use msecs_to_jiffies_timeout, then replace the msleep with an open-coded version that avoids the extra +1 jiffy. - Try to add units to every variable name so we don't confuse jiffies with milliseconds.

2014-01-24drm/i915: init the DP panel power seq variables earlierPaulo Zanoni
Our driver has two different ways of waiting for panel power sequencing delays. One of these ways is through ironlake_wait_panel_status, which implicitly uses the values written to our registers. The other way is through the functions that call intel_wait_until_after, and on this case we do direct msleep() calls on the intel_dp->xxx_delay variables. Function intel_dp_init_panel_power_sequencer is responsible for initializing the _delay variables and deciding which values we need to write to the registers, but it does not write these values to the registers. Only at intel_dp_init_panel_power_sequencer_registers we actually do this write. Then problem is that when we call intel_dp_i2c_init, we will get some I2C calls, which will trigger a VDD enable, which will make use of the panel power sequencing registers and the _delay variables, so we need to have both ready by this time. Today, when this happens, the _delay variables are zero (because they were not computed) and the panel power sequence registers contain whatever values were written by the BIOS (which are usually correct). What this patch does is to make sure that function intel_dp_init_panel_power_sequencer is called earlier, so by the time we call intel_dp_i2c_init, the _delay variables will already be initialized. The actual registers won't contain their final values, but at least they will contain the values set by the BIOS. The good side is that we were reading the values, but were not using them for anything (because we were just skipping the msleep(0) calls), so this "fix" shouldn't fix any real existing bugs. I was only able to identify the problem because I added some debug code to check how much time time we were saving with my previous patch.

This reverts commit 446f254566ea8911c9e19c7bc8a162fc0e53cf31. I've left the masking in the pageflip code since that seems to be some useful piece of preemptive robustness. Iirc I've merged this patch under the assumption that the BIOS leaves some random gunk in the lower bits and gets unhappy if we trample on them. We have quite a few case like this, so this made sense. Now I've just learned that there's actual hardware features bits in the low 12 bits, and the kernel needs to preserve them to allow a userspace blob to do its job. Given Dave Airlie's clear stance on userspace blob drivers I've quickly chatted with him and he doesn't seem too happy. So let's revert this. If there are indeed bits that we must preserve in this range then we can ressurrect this patch, but with proper documentation for those bits supplied. And we probably also need to think a bit about interactions with our driver.

2014-01-23drm/tegra: Obtain head number from DTThierry Reding
The head number of a given display controller is fixed in hardware and required to program outputs appropriately. Relying on the driver probe order to determine this number will not work, since that could yield a situation where the second head was probed first and would be assigned head number 0 instead of 1. By explicitly specifying the head number in the device tree, it is no longer necessary to rely on these assumptions. As a fallback, if the property isn't available, derive the head number from the display controller node's position in the device tree. That's somewhat more reliable than the previous default but not a proper solution. Tested-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
