28812fe11a driver-core: Add attribute argument to class_attribute show/store
Passing the attribute to the low level IO functions allows all kinds
of cleanups, by sharing low level IO code without requiring
an own function for every piece of data.

Also drivers can extend the attributes with own data fields
and use that in the low level function.

This makes the class attributes the same as sysdev_class attributes
and plain attributes.

This will allow further cleanups in drivers.

Full tree sweep converting all users.

b8fa05719b Revert "lib: build list_sort() only if needed"
This reverts commit a069c266ae.

It turns ou that not only was it missing a case (XFS) that needed it,
but perhaps more importantly, people sometimes want to enable new
modules that they hadn't had enabled before, and if such a module uses
list_sort(), it can't easily be inserted any more.

So rather than add a "select LIST_SORT" to the XFS case, just leave it
compiled in.  It's not all _that_ big, after all, and the inconvenience
isn't worth it.

6a9ee8af34 vga_switcheroo: initial implementation (v15)
Many new laptops now come with 2 gpus, one to be used for low power
modes and one for gaming/on-ac applications. These GPUs are typically
wired to the laptop panel and VGA ports via a multiplexer unit which
is controlled via ACPI methods.

4 combinations of systems typically exist - with 2 ACPI methods.
Intel/ATI - Lenovo W500/T500 - use ATPX ACPI method
ATI/ATI - some ASUS - use ATPX ACPI Method
Intel/Nvidia - - use _DSM ACPI method
Nvidia/Nvidia -  - use _DSM ACPI method.

TODO:
This patch adds support for the ATPX method and initial bits
for the _DSM methods that need to written by someone with
access to the hardware.
Add a proper non-debugfs interface - need to get some proper
testing first.

v2: add power up/down support for both devices
on W500 puts i915/radeon into D3 and cuts power to radeon.

v3: redo probing methods, no DMI list, drm devices call to
register with switcheroo, it tries to find an ATPX method on
any device and once there is two devices + ATPX it inits the
switcher.

v4: ATPX msg handling using buffers - should work on more machines

v5: rearchitect after more mjg59 discussion - move ATPX handling to
    radeon driver.

v6: add file headers + initial nouveau bits (to be filled out).

v7: merge delayed switcher code.

v8: avoid suspend/resume of gpu that is off

v9: rearchitect - mjg59 is always right. - move all ATPX code to
radeon, should allow simpler DSM also proper ATRM handling

v10: add ATRM support for radeon BIOS, add mutex to lock vgasr_priv

v11: fix bug in resuming Intel for 2nd time.

v12: start fixing up nvidia code blindly.

v13: blindly guess at finishing nvidia code

v14: remove radeon audio hacks - fix up intel resume more like upstream

v15: clean up printks + remove unnecessary igd/dis pointers

mount debugfs

/sys/kernel/debug/vgaswitcheroo/switch - should exist if ATPX detected
 + 2 cards.

DIS - immediate change to discrete
IGD - immediate change to IGD
DDIS - delayed change to discrete
DIGD - delayed change to IGD
ON - turn on not in use
OFF - turn off not in use

Tested on W500 (Intel/ATI) and T500 (Intel/ATI)

3464f11496 Revert "drm/radeon/kms: disable HDMI audio for now on rv710/rv730"
This commit "disabled" audio on RV710 and RV740 only, leaving RV770 and RV730.
The order is: CHIP_RV770 < CHIP_RV730 < CHIP_RV710 < CHIP_RV740.

It is not needed anway, as we do not even try to enable audio on RV770 and
newer. We call initializing function in r600.c only, not in rv770.c.

If there is something causing green tinges, it's HDMI mode setting for encoder
and I will try to debug that.

566d84d172 drm/radeon: r100/r200 ums: block ability for userspace app to trash 0 page and beyond
radeon's have a special ability to passthrough writes in their internal
memory space directly to PCI, this ability means that if some of the internal
surfaces like the depth buffer point at 0x0, any writes to these will
go directly to RAM at 0x0 via PCI busmastering.

Now mesa used to always emit clears after emitting state, since the
radeon mesa driver was refactored a year or more ago, it was found it
could generate a clear request without ever sending any setup state to the
card. So the clear would attempt to clear the depth buffer at 0x0, which
would overwrite main memory at this point. fs corruption ensues.

Also once one app did this correctly, it would never get set back to 0
making this messy to reproduce.

The kernel should block this from happening as mesa runs without privs,
though it does require the user be connected to the current running X session.

This patch implements a check to make sure the depth offset has been set
before a depth clear occurs and if it finds one it prints a warning and
ignores the depth clear request. There is also a mesa fix to avoid sending
the badness going into mesa.

This only affects r100/r200 GPUs in user modesetting mode.

469d129664 drm/i915: enable/disable LVDS port at DPMS time
It would be good to disable the LVDS port when we shut down the panel
to save power.  We haven't done so until now because we had trouble
getting the right LVDS parameters from the BIOS.  I think we're past
that now, so enabling and disabling the port should be safe, though it
would probably be made cleaner with some additional changes to the
display code, where we also bang on the LVDS reg to set the pairing
correctly etc.

Seems to save a bit of power (up to 300mW in my basic wattsup
meter testing).

The fence_list should be lru ordered for otherwise we might try
to steal a fence reg from an active object even though there are
fences from inactive objects available. lru ordering was obeyed

Fixing this cause the code to indent way to much, so I've extracted

This has a few functional changes against the old code:

* a few more unnecessary loads and stores to the drm_i915_fence_reg

* zaps any userspace mappings before doing other flushes. Only changes
  anything when userspace does racy stuff against itself.

* also flush GTT domain. This is a noop, but still try to keep the

a1606a9596 drm/nouveau: new gem pushbuf interface, bump to 0.0.16
This commit breaks the userspace interface, and requires a new libdrm for
nouveau to operate again.

The multiple GEM_PUSHBUF ioctls that were present in 0.0.15 for
compatibility purposes are now gone, and replaced with the new ioctl which
allows for multiple push buffers to be submitted (necessary for hw index
buffers in the nv50 3d driver) and relocations to be applied on any buffer.

A number of other ioctls (CARD_INIT, GEM_PIN, GEM_UNPIN) that were needed
for userspace modesetting have also been removed.

9a391ad8a2 drm/nv50: switch to indirect push buffer controls
PFIFO on G80 and up has a new mode where the main ring buffer is simply a
ring of pointers to indirect buffers containing the actual command/data
packets.  In order to be able to implement index buffers in the 3D driver
we need to be able to submit data-only push buffers right after the cmd
packet header, which is only possible using the new command submission
method.

This commit doesn't make it possible to implement index buffers yet, some
userspace interface changes will be required, but it does allow for
testing/debugging of the hardware-side support in the meantime.

b4fe945405 drm/radeon: Fix memory allocation failures in the preKMS command stream checking.
Allocation of single large block of memory may fail under memory
presure. drm_buffer object can hold one large block of data in
multiple independ pages which preents alloation failures.

This patch converts all access to command stream to use drm_buffer
interface. All direct access to array has to go tough drm_buffer
functions to get correct pointer.

Outputting the command stream to ring buffer needs to be awear of
the split nature of drm_buffer. The output operation requires the
new OUT_RING_DRM_BUFFER.

7a9f0dd9c4 drm: Add generic multipart buffer.
Allocating multiple pages of memory for data that is coming
from user space may fail. To fix memory allocation failures
the buffer object should be split to multiple independ pages.

drm buffer provides generic interface to copy and process
large data arrays from user space.

Interface includes allocation and free functions to allocate
the buffer object and data storage pages.

All access operations are performed relative to a internal
pointer which is advanced with drm_buffer_advance function.

The buffer can be accessed using drm_buffer_pointer_to_XXX
functions if it is known that requested object doesn't split
over a page boundary. These functions don't do any error
checking to maximize performance.

If there is large object which could be split there is special
drm_buffer_read_object function. drm_buffer_read_object takes
a pointer as argument which is used as temporary store for
data if it is split over boundary in the buffer.

9df30794f6 drm/i915: Record batch buffer following GPU error
In order to improve our diagnostic capabilities following a GPU hang
and subsequent reset, we need to record the batch buffer that triggered
the error. We assume that the current batch buffer, plus a few details
about what else is on the active list, will be sufficient -- at the very
least an improvement over nothing.

The extra information is stored in /debug/dri/.../i915_error_state
following an error, and may be decoded using
intel_gpu_tools/tools/intel_error_decode.

v2: Avoid excessive work under spinlocks.
v3: Include ringbuffer for later analysis.
v4: Use kunmap correctly and record more buffer state.
v5: Search ringbuffer for current batch buffer
v6: Use a work fn for the impossible IRQ error case.
v7: Avoid non-atomic paths whilst in IRQ context.

61caf87cb5 i915 / PM: Fix hibernate regression caused by suspend/resume splitting
Commit 84b79f8d28 (drm/i915: Fix crash
while aborting hibernation) attempted to fix a regression introduced
by commit cbda12d77e (drm/i915:
implement new pm ops for i915), but it went too far trying to split
the freeze/suspend and resume/thaw parts of the code.  As a result,
it introduced another regression, which only is visible on some systems.

Fix the problem by merging i915_drm_suspend() with
i915_drm_freeze() and moving some code from i915_resume()
into i915_drm_thaw(), so that intel_opregion_free() and
intel_opregion_init() are also executed in the freeze and thaw code
paths, respectively.

ee980b8003 drm/i915: enable memory self refresh on 9xx
Enabling memory self refresh (SR) on 9xx needs to set additional
register bits. On 945, we need bit 31 of FW_BLC_SELF to enable the
write to self refresh bit and bit 16 to enable the write of self
refresh watermark. On 915, bit 12 of INSTPM is used to enable SR.

SR will take effect when CPU enters C3+ state and its entry/exit
should be automatically controlled by H/W, driver only needs to set
SR enable bits in wm update. But this isn't safe in my test on 945
because GPU is hung. So this patch explicitly enables SR when GPU
is idle, and disables SR when it is busy. In my test on a netbook of
945GSE chipset, it saves about 0.8W idle power.

There is 3 different distinct states for an indirect buffer (IB) :
  1- free with no fence
  2- free with a fence
  3- non free (fence doesn't matter)
Previous code mixed case 2 & 3 in a single one leading to possible
catastrophique failure. This patch rework the handling and properly
separate each case. So when you get ib we set the ib as non free and
fence status doesn't matter. Fence become active (ie has a meaning
for the ib code) once the ib is scheduled or free. This patch also
get rid of the alloc bitmap as it was overkill, we know go through

one the will be free.

Get rid of _location and use _start/_end also simplify the
computation of vram_start|end & gtt_start|end. For R1XX-R2XX
we place VRAM at the same address of PCI aperture, those GPU
shouldn't have much memory and seems to behave better when
setup that way. For R3XX and newer we place VRAM at 0. For
R6XX-R7XX AGP we place VRAM before or after AGP aperture this
might limit to limit the VRAM size but it's very unlikely.
For IGP we don't change the VRAM placement.

Tested on (compiz,quake3,suspend/resume):
PCI/PCIE:RV280,R420,RV515,RV570,RV610,RV710
AGP:RV100,RV280,R420,RV350,RV620(RPB*),RV730
IGP:RS480(RPB*),RS690,RS780(RPB*),RS880

6cb8e1f71c drm/radeon/kms: fix bo's fence association
Previous code did associate fence to bo before the fence was emited
and it also didn't lock protected access to ttm sync_obj member.
Both of this flaw leads to possible race between different code
path. This patch fix this by associating fence only once the fence
is emitted and properly lock protect access to sync_obj member of
ttm.

Fix:

e821767beb drm/radeon/kms: fix indirect buffer management V2
There is 3 different distinct states for an indirect buffer (IB) :
  1- free with no fence
  2- free with a fence
  3- non free (fence doesn't matter)
Previous code mixed case 2 & 3 in a single one leading to possible
catastrophique failure. This patch rework the handling and properly
separate each case. So when you get ib we set the ib as non free and
fence status doesn't matter. Fence become active (ie has a meaning
for the ib code) once the ib is scheduled or free. This patch also
get rid of the alloc bitmap as it was overkill, we know go through
IB pool list like in a ring buffer as the oldest IB is the first
one the will be free.

Fix :
https://bugs.freedesktop.org/show_bug.cgi?id=26438
and likely other bugs.

V2 remove the scheduled list, it's useless now, fix free ib scanning

Noticed on a DEC Alpha.

Start up into console mode caused 15 unaligned accesses, and starting X
caused another 48.

6b79b264ce No need to patch AMD-provided drivers/gpu/drm/radeon/atombios.h
This is partial revert of commit 9404c9c392d5 ("Fix misspelling of "should"
and "shouldn't" in comments"). According to Dave Airlie:

	"Can we drop any cleanups to atombios.h? This file comes from
	AMD and we normally drop it into place, so they just get overwritten
	next time."

radeon_cs kfree the tracker structure but for r6xx/r7xx we want
to kfree it inside the parse function because we share it with
the UMS code path. Set tracker to NULL after freeing it will
avoid double free.
