* drm/i915: wait for actual vblank, not just 20msJesse Barnes2010-08-22
| | | | | | | | | | | | | | Waiting for a hard coded 20ms isn't always enough to make sure a vblank period has actually occurred, so add code to make sure we really have passed through a vblank period (or that the pipe is off when disabling). This prevents problems with mode setting and link training, and seems to fix a bug like https://bugs.freedesktop.org/show_bug.cgi?id=29278, but on an HP 8440p instead. Hopefully also fixes https://bugs.freedesktop.org/show_bug.cgi?id=29141. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>

* drm/i915: Ensure that while(INREG()) are bounded (v2)Chris Wilson2010-08-09
| | | | | | | | | | | | | | Add a new macro, wait_for, to simplify the act of waiting on a register to change state. wait_for() takes three arguments, the condition to inspect on every loop, the maximum amount of time to wait and whether to yield the cpu for a length of time after each check. v2: Upgrade failure messages to DRM_ERROR on the suggestion of Eric Anholt. We do not expect to hit these conditions as they reflect programming errors, so if we do we want to be notified.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The docs warn that to position the cursor such that no part of it is visible on the pipe is an undefined operation. Avoid such circumstances upon changing the mode, or at any other time, by unsetting the cursor if it moves out of bounds. "For normal high resolution display modes, the cursor must have at least a single pixel positioned over the active screen.” (p143, p148 of the hardware registers docs).

* | drm/i915: Rename intel_output to intel_encoder.Eric Anholt2010-03-25
|/ | | | | | | | | | | | | | | | | | The intel_output naming is inherited from the UMS code, which had a structure of screen -> CRTC -> output. The DRM code has an additional notion of encoder/connector, so the structure is screen -> CRTC -> encoder -> connector. This is a useful structure for SDVO encoders which can support multiple connectors (each of which requires different programming in the one encoder and could be connected to different CRTCs), or for DVI-I, where multiple encoders feed into the connector for whether it's used for digital or analog. Most of our code is encoder-related, so transition it to talking about encoders before we start trying to distinguish connectors.

* drm/i915: implement drmmode overlay support v4Daniel Vetter2009-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements intel overlay support for kms via a device-specific ioctl. Thomas Hellstrom brought up the idea of a general ioctl (on dri-devel). We've reached the conclusion that such an infrastructure only makes sense when multiple kms overlay implementations exists, which atm don't (and it doesn't look like this is gonna change). Open issues: - Runs in sync with the gpu, i.e. unnecessary waiting. I've decided to wait on this because the hw tends to hang when changing something in this area. I left some dummy functions as infrastructure. - polyphase filtering uses a static table. - uses uninterruptible sleeps. Unfortunately the alternatives may unnecessarily wedged the hw if/when we timeout too early (and userspace only overloaded the batch buffers with stuff worth a few secs of gpu time). Changes since v1: - fix off-by-one misconception on my side. This fixes fullscreen playback. Changes since v2: - add underrun detection as spec'ed for i965. - flush caches properly, fixing visual corruptions. Changes since v4: - fix up cache flushing of overlay memory regs. - killed require_pipe_a logic - it hangs the chip.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several sources of unnecessary power consumption on Intel graphics systems. The first is the LVDS clock. TFTs don't suffer from persistence issues like CRTs, and so we can reduce the LVDS refresh rate when the screen is idle. It will be automatically upclocked when userspace triggers graphical activity. Beyond that, we can enable memory self refresh. This allows the memory to go into a lower power state when the graphics are idle. Finally, we can drop some clocks on the gpu itself. All of these things can be reenabled between frames when GPU activity is triggered, and so there should be no user visible graphical changes.

|/ | | | | | | | | | | | | | | | | Based on Bspec each encoder has different sharing pipe property, i.e. Integrated or SDVO TV both will occupy one pipe exclusively, and sdvo-non-tv and crt are allowed to share one. The patch moves sharing judgment into differnet output functions, and sets the right clone bit. This fixes both HDMI outputs choosing the same pipe. https://bugs.freedesktop.org/show_bug.cgi?id=22247 Signed-off-by: Ma Ling <ling.ma@intel.com> Reviewed-by : Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>
* drm/i915: Add eDP support on IGDNG mobile chipZhenyu Wang2009-07-29
| | | | | | | | | | | | | This adds embedded DisplayPort support on next mobile chip which aims to replace origin LVDS port. VBT's driver feature block has been used to determine the type of current internal panel for eDP or LVDS. Currently no panel fitting support for eDP and backlight control would be added in future.

* drm/i915: Change I2C api to pass around i2c_adaptersKeith Packard2009-06-18
| | | | | | | | | | | | The existing API passed around intel_i2c_chan pointers, which are dependent on the i2c bit-banging algo. This precluded the driver from using outputs which use a different algo. Switching to the more general i2c_adpater allows the driver to support non bit-banging DDC. This also required moving the slave address into the output private structures. Signed-off-by: Keith Packard <keithp@keithp.com>
* drm/i915: Add new GET_PIPE_FROM_CRTC_ID ioctl.Carl Worth2009-05-14
| | | | | | | | | | | | This allows userlevel code to discover the pipe number corresponding to a given CRTC ID. This is necessary for doing pipe-specific operations such as waiting for vblank on a given CRTC. Failure to use the right pipe mapping can result in GPU hangs, or at least failure to actually sync to vblank.
