DRM: i915: add mode setting support
This commit adds i915 driver support for the DRM mode setting APIs.
Currently, VGA, LVDS, SDVO DVI & VGA, TV and DVO LVDS outputs are
supported. HDMI, DisplayPort and additional SDVO output support will
follow.
Support for the mode setting code is controlled by the new 'modeset'
module option. A new config option, CONFIG_DRM_I915_KMS controls the
default behavior, and whether a PCI ID list is built into the module for
use by user level module utilities.
Note that if mode setting is enabled, user level drivers that access
display registers directly or that don't use the kernel graphics memory
manager will likely corrupt kernel graphics memory, disrupt output
configuration (possibly leading to hangs and/or blank displays), and
prevent panic/oops messages from appearing. So use caution when
enabling this code; be sure your user level code supports the new
interfaces.
A new SysRq key, 'g', provides emergency support for switching back to
the kernel's framebuffer console; which is useful for testing.

drm/i915: Reorganize display pipe register accesses
RFCv2: Reorganize array indexing so that full offsets can be used as
is. It makes grepping for registers in i915_reg.h much easier. Also
move offset arrays to intel_device_info.
v1: Fixed offsets for VLV, proper eDP handling
v2: Fixed BCLRPAT, PIPESRC, PIPECONF and DSP* macros.
v3: Added EDP pipe comment, removed redundant offset arrays for
MSA_MISC and DDI_FUNC_CTL.
v4: Rename patch and report object size increase.
v5: Change location of commas, add PIPE_EDP into enum pipe
v6: Insert PIPE_EDP_OFFSET into pipe offset array
v7: Set I915_MAX_PIPES back to 3, change more registers accessors
to use the new macros, get rid of _PIPE_INC and add dev_priv
as a parameter where required by the new macros.
Upcoming hardware will not have the various display pipe register
ranges evenly spaced in memory. Change register address calculations
into array lookups.
Tested on SNB, VLV, IVB, Gen2 and HSW w/eDP.
I left the UMS cruft untouched.

drm/i915: Reorganize display pipe register accesses
RFCv2: Reorganize array indexing so that full offsets can be used as
is. It makes grepping for registers in i915_reg.h much easier. Also
move offset arrays to intel_device_info.
v1: Fixed offsets for VLV, proper eDP handling
v2: Fixed BCLRPAT, PIPESRC, PIPECONF and DSP* macros.
v3: Added EDP pipe comment, removed redundant offset arrays for
MSA_MISC and DDI_FUNC_CTL.
v4: Rename patch and report object size increase.
v5: Change location of commas, add PIPE_EDP into enum pipe
v6: Insert PIPE_EDP_OFFSET into pipe offset array
v7: Set I915_MAX_PIPES back to 3, change more registers accessors
to use the new macros, get rid of _PIPE_INC and add dev_priv
as a parameter where required by the new macros.
Upcoming hardware will not have the various display pipe register
ranges evenly spaced in memory. Change register address calculations
into array lookups.
Tested on SNB, VLV, IVB, Gen2 and HSW w/eDP.
I left the UMS cruft untouched.

drm/i915: Reorganize display pipe register accesses
RFCv2: Reorganize array indexing so that full offsets can be used as
is. It makes grepping for registers in i915_reg.h much easier. Also
move offset arrays to intel_device_info.
v1: Fixed offsets for VLV, proper eDP handling
v2: Fixed BCLRPAT, PIPESRC, PIPECONF and DSP* macros.
v3: Added EDP pipe comment, removed redundant offset arrays for
MSA_MISC and DDI_FUNC_CTL.
v4: Rename patch and report object size increase.
v5: Change location of commas, add PIPE_EDP into enum pipe
v6: Insert PIPE_EDP_OFFSET into pipe offset array
v7: Set I915_MAX_PIPES back to 3, change more registers accessors
to use the new macros, get rid of _PIPE_INC and add dev_priv
as a parameter where required by the new macros.
Upcoming hardware will not have the various display pipe register
ranges evenly spaced in memory. Change register address calculations
into array lookups.
Tested on SNB, VLV, IVB, Gen2 and HSW w/eDP.
I left the UMS cruft untouched.

drm/i915: Reorganize display pipe register accesses
RFCv2: Reorganize array indexing so that full offsets can be used as
is. It makes grepping for registers in i915_reg.h much easier. Also
move offset arrays to intel_device_info.
v1: Fixed offsets for VLV, proper eDP handling
v2: Fixed BCLRPAT, PIPESRC, PIPECONF and DSP* macros.
v3: Added EDP pipe comment, removed redundant offset arrays for
MSA_MISC and DDI_FUNC_CTL.
v4: Rename patch and report object size increase.
v5: Change location of commas, add PIPE_EDP into enum pipe
v6: Insert PIPE_EDP_OFFSET into pipe offset array
v7: Set I915_MAX_PIPES back to 3, change more registers accessors
to use the new macros, get rid of _PIPE_INC and add dev_priv
as a parameter where required by the new macros.
Upcoming hardware will not have the various display pipe register
ranges evenly spaced in memory. Change register address calculations
into array lookups.
Tested on SNB, VLV, IVB, Gen2 and HSW w/eDP.
I left the UMS cruft untouched.

DRM: i915: add mode setting support
This commit adds i915 driver support for the DRM mode setting APIs.
Currently, VGA, LVDS, SDVO DVI & VGA, TV and DVO LVDS outputs are
supported. HDMI, DisplayPort and additional SDVO output support will
follow.
Support for the mode setting code is controlled by the new 'modeset'
module option. A new config option, CONFIG_DRM_I915_KMS controls the
default behavior, and whether a PCI ID list is built into the module for
use by user level module utilities.
Note that if mode setting is enabled, user level drivers that access
display registers directly or that don't use the kernel graphics memory
manager will likely corrupt kernel graphics memory, disrupt output
configuration (possibly leading to hangs and/or blank displays), and
prevent panic/oops messages from appearing. So use caution when
enabling this code; be sure your user level code supports the new
interfaces.
A new SysRq key, 'g', provides emergency support for switching back to
the kernel's framebuffer console; which is useful for testing.

i915: ignore lid open event when resuming
i915 driver needs to do modeset when
1. system resumes from sleep
2. lid is opened
In PM_SUSPEND_MEM state, all the GPEs are cleared when system resumes,
thus it is the i915_resume code does the modeset rather than intel_lid_notify().
But in PM_SUSPEND_FREEZE state, this will be broken because
system is still responsive to the lid events.
1. When we close the lid in Freeze state, intel_lid_notify() sets modeset_on_lid.
2. When we reopen the lid, intel_lid_notify() will do a modeset,
before the system is resumed.

three different modeset flags are introduced in this patch
MODESET_ON_LID_OPEN: do modeset on next lid open event
MODESET_DONE: modeset already done
MODESET_SUSPENDED: suspended, only do modeset when system is resumed
In this way,
1. when lid is closed, MODESET_ON_LID_OPEN is set so that
we'll do modeset on next lid open event.
2. when lid is opened, MODESET_DONE is set
so that duplicate lid open events will be ignored.
3. when system suspends, MODESET_SUSPENDED is set.
In this case, we will not do modeset on any lid events.
Plus, locking mechanism is also introduced to avoid racing.

drm: Split connection_mutex out of mode_config.mutex (v3)
After the split-out of crtc locks from the big mode_config.mutex
there's still two major areas it protects:
- Various connector probe states, like connector->status, EDID
properties, probed mode lists and similar information.
- The links from connector->encoder and encoder->crtc and other
modeset-relevant connector state (e.g. properties which control the
panel fitter).
The later is used by modeset operations. But they don't really care
about the former since it's allowed to e.g. enable a disconnected VGA
output or with a mode not in the probed list.
Thus far this hasn't been a problem, but for the atomic modeset
conversion Rob Clark needs to convert all modeset relevant locks into
w/w locks. This is required because the order of acquisition is
determined by how userspace supplies the atomic modeset data. This has
run into troubles in the detect path since the i915 load detect code
needs _both_ protections offered by the mode_config.mutex: It updates
probe state and it needs to change the modeset configuration to enable
the temporary load detect pipe.
The big deal here is that for the probe/detect users of this lock a
plain mutex fits best, but for atomic modesets we really want a w/w
mutex. To fix this lets split out a new connection_mutex lock for the
modeset relevant parts.
For simplicity I've decided to only add one additional lock for all
connector/encoder links and modeset configuration states. We have
piles of different modeset objects in addition to those (like bridges
or panels), so adding per-object locks would be much more effort.
Also, we're guaranteed (at least for now) to do a full modeset if we
need to acquire this lock. Which means that fine-grained locking is
fairly irrelevant compared to the amount of time the full modeset will
take.
I've done a full audit, and there's just a few things that justify
special focus:
- Locking in drm_sysfs.c is almost completely absent. We should
sprinkle mode_config.connection_mutex over this file a bit, but
since it already lacks mode_config.mutex this patch wont make the
situation any worse. This is material for a follow-up patch.
- omap has a omap_framebuffer_flush function which walks the
connector->encoder->crtc links and is called from many contexts.
Some look like they don't acquire mode_config.mutex, so this is
already racy. Again fixing this is material for a separate patch.
- The radeon hot_plug function to retrain DP links looks at
connector->dpms. Currently this happens without any locking, so is
already racy. I think radeon_hotplug_work_func should gain
mutex_lock/unlock calls for the mode_config.connection_mutex.
- Same applies to i915's intel_dp_hot_plug. But again, this is already
racy.
- i915 load_detect code needs to acquire this lock. Which means the
w/w dance due to Rob's work will be nicely contained to _just_ this
function.
I've added fixme comments everywhere where it looks suspicious but in
the sysfs code. After a quick irc discussion with Dave Airlie it
sounds like the lack of locking in there is due to sysfs cleanup fun
at module unload.
v1: original (only compile tested)
v2: missing mutex_init(), etc (from Rob Clark)
v3: i915 needs more care in the conversion:
- Protect the edp pp logic with the connection_mutex.
- Use connection_mutex in the backlight code due to
get_pipe_from_connector.
- Use drm_modeset_lock_all in suspend/resume paths.
- Update lock checks in the overlay code.

i915: ignore lid open event when resuming
i915 driver needs to do modeset when
1. system resumes from sleep
2. lid is opened
In PM_SUSPEND_MEM state, all the GPEs are cleared when system resumes,
thus it is the i915_resume code does the modeset rather than intel_lid_notify().
But in PM_SUSPEND_FREEZE state, this will be broken because
system is still responsive to the lid events.
1. When we close the lid in Freeze state, intel_lid_notify() sets modeset_on_lid.
2. When we reopen the lid, intel_lid_notify() will do a modeset,
before the system is resumed.
here is the error log,

three different modeset flags are introduced in this patch
MODESET_ON_LID_OPEN: do modeset on next lid open event
MODESET_DONE: modeset already done
MODESET_SUSPENDED: suspended, only do modeset when system is resumed
In this way,
1. when lid is closed, MODESET_ON_LID_OPEN is set so that
we'll do modeset on next lid open event.
2. when lid is opened, MODESET_DONE is set
so that duplicate lid open events will be ignored.
3. when system suspends, MODESET_SUSPENDED is set.
In this case, we will not do modeset on any lid events.
Plus, locking mechanism is also introduced to avoid racing.

|
|
|
|
* These have no effect on the driver's operation, so we don't save/restore

* them to reduce the overhead.
|
|
|
|
* - Registers that are fully setup by an initialization function called from

|

drm/i915: make PC8 be part of runtime PM suspend/resume
Currently, when our driver becomes idle for i915.pc8_timeout (default:
5s) we enable PC8, so we save some power, but not everything we can.
Then, while PC8 is enabled, if we stay idle for more
autosuspend_delay_ms (default: 10s) we'll enter runtime PM and put the
graphics device in D3 state, saving even more power. The two features
are separate things with increasing levels of power savings, but if we
disable PC8 we'll never get into D3.
While from the modularity point of view it would be nice to keep these
features as separate, we have reasons to merge them:
- We are not aware of anybody wanting a "PC8 without D3" environment.
- If we keep both features as separate, we'll have to to test both
PC8 and PC8+D3 code paths. We're already having a major pain to
make QA do automated testing of just one thing, testing both paths
will cost even more.
- Only Haswell+ supports PC8, so if we want to add runtime PM support
to, for example, IVB, we'll have to copy some code from the PC8
feature to runtime PM, so merging both features as a single thing
will make it easier for enabling runtime PM on other platforms.
This patch only does the very basic steps required to have PC8 and
runtime PM merged on a single feature: the next patches will take care
of cleaning up everything.
v2: - Rebase.
v3: - Rebase.
- Fully remove the deprecated i915 params since Daniel doesn't
consider them as part of the ABI.
v4: - Rebase.
- Fix typo in the commit message.
v5: - Rebase, again.
- Add a huge comment explaining the different forcewake usage
(Chris, Daniel).
- Use open-coded forcewake functions (Daniel).

DRM: i915: add mode setting support
This commit adds i915 driver support for the DRM mode setting APIs.
Currently, VGA, LVDS, SDVO DVI & VGA, TV and DVO LVDS outputs are
supported. HDMI, DisplayPort and additional SDVO output support will
follow.
Support for the mode setting code is controlled by the new 'modeset'
module option. A new config option, CONFIG_DRM_I915_KMS controls the
default behavior, and whether a PCI ID list is built into the module for
use by user level module utilities.
Note that if mode setting is enabled, user level drivers that access
display registers directly or that don't use the kernel graphics memory
manager will likely corrupt kernel graphics memory, disrupt output
configuration (possibly leading to hangs and/or blank displays), and
prevent panic/oops messages from appearing. So use caution when
enabling this code; be sure your user level code supports the new
interfaces.
A new SysRq key, 'g', provides emergency support for switching back to
the kernel's framebuffer console; which is useful for testing.
