Subject: drm/nv50: Remove redundant/incorrect ctxvals initialisation.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

11c/004 offset corresponds to PGRAPH reg 0x400828, and is initialised
earlier anyway by both our ctxprog generator and blob ctxvals. It's
actually incorrect with the generator, since we use different layout
on pre-NVA0.

MIME-Version: 1.0

NV50 is nice and has a switch that autoaligns stuff for us. Pre-NV50,
we need to align input bitmap width manually.

Subject: drm/nv50: Improve PGRAPH interrupt handling.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This makes nouveau recognise and report more kinds of PGRAPH errors, as
well as prevent GPU lockups resulting from some of them.

Lots of guesswork was involved and some part of this is probably
incorrect. Some potential-lockuop situations are handled by just
resetting a whole PGRAPH subunit, which doesn't sound like a "proper"
solution, but seems to work just fine... for now.

Subject: drm/nv50: fix connector table parsing for some cards

The connector table index in the DCB entry for each output type is an
index into the connector table, and does *not* necessarily match up
with what was previously called "index" in the connector table entries
themselves.

Not real sure what that index is exactly, renamed to "index2" as we
still use it to prevent creating multiple TV connectors.

Subject: drm/radeon/kms: catch atombios infinite loop and break out of it

In somecase the atombios code might lead to infinite loop because
the GPU is in broken state, this patch track the jump history and
will abort atombios execution if we are stuck executing the same
jump for more than 1sec. Note that otherwise in some case we might
enter an infinite loop in the kernel context which is bad.

Subject: drm/nouveau: Never evict VRAM buffers to system.

VRAM->system is a synchronous operation: it involves scheduling a
VRAM->TT DMA transfer and stalling the CPU until it's finished so that
we can unbind the new memory from the translation tables. VRAM->TT can
always be performed asynchronously, even if TT is already full and we
have to move something out of it.

Additionally, allowing VRAM->system behaves badly under heavy memory
pressure because once we run out of TT, stuff starts to be moved back
and forth between VRAM and system, and the TT contents are hardly
renewed.

Subject: drm/radeon/kms/atom: spread spectrum fix

The atom spread spectrum table does not always
disable ss.  Explicitly disable it and then use
the atom table to enable later if needed (currently
only used for LVDS).

Fixes display issues on some systems.

Subject: drm/radeon/kms: further spread spectrum fixes

Adjust modeset ordering to fix spread spectrum.
The spread spectrum command table relies on the
crtc routing to already be set in order to work
properly on some asics.

Should fix fdo bug 25741.

Subject: drm/radeon/kms: clean assigning HDMI blocks to encoders
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We almost always used first HDMI block for first encoder and second for sencod.
Exception was KLDSCP_LVTMA. Analyzing code picking DIG encoder shows the same
behaviour. It shows HDMI block are related to DIGs, which relation we now use.

Subject: drm/radeon/kms: add HDMI code for pre-DCE3 R6xx GPUs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Older GPUs are little different, HDMI blocks are not hard-wired, but routable.
We should just find some free HDMI block and route it to choosen encoder. In
case of RS6x0 there is only one HDMI block, we don't enable HDMI on RS6x00 yet
however.

Subject: drm/radeon/r600: add missing license and comments to
 r600_blit_shaders.c

R6xx+ cards need to use the 3D engine to blit data which requires
quite a bit of hw state setup.  Rather than pull the whole 3D driver
(which normally generates the 3D state) into the DRM, we opt to use
statically generated state tables.  The regsiter state and shaders
were hand generated to support blitting functionality.  See the 3D
driver or documentation for descriptions of the registers and
shader instructions.

Subject: drm/radeon/kms: switch to condition waiting for reclocking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We tried to implement interruptible waiting with timeout (it was broken
anyway) which was not a good idea as explained by Andrew. It's possible
to avoid using additional variable but actually it inroduces using more
complex in-kernel tools. So simply add one variable for condition.

From: "Robert P. J. Day" <rpjday@crashcourse.ca>

Subject: drm: "kobject_init/kobject_add" -> "kobject_init_and_add".

Replace sequential calls to kobject_init() and kobject_add() with the
combo wrapper kobject_init_and_add(), which provides the same
semantics.

vmwfgx uses framebuffer interfaces, so it should depend on FB.
Otherwise it has these build errors (e.g., when CONFIG_FB=m):

Subject: drm: remove the EDID blob stored in the EDID property when it is
 disconnected

Now the EDID property will be updated when the corresponding EDID can be
obtained from the external display device. But after the external device
is plugged-out, the EDID property is not updated. In such case we still
get the corresponding EDID property although it is already detected as
disconnected.

And move asic init plus a few related functions from radeon_device.c
to it. This file will hold all the asic structures in the future,
but atm they're still stuck in radeon_asic.h.

Subject: drm/radeon: move asic structs to radeon_asic.c

With these static structs gone, radeon_asic.h is a real header file
and can be used as such.

Subject: drm/radeon/kms: expose thermal/fan i2c buses

Look up i2c bus in the power table and expose it.
You'll need to load a hwmon driver for any chips
on the bus, this patch just exposes the bus.

RS4xx+ IGP chips use an internal gart, however,
some of them have the agp cap bits set in their pci
configs.  Make sure to clear the AGP flag as AGP will
not work with them.

Should fix fdo bug 27225

Subject: drm/radeon/kms: remove lvds quirks

- no longer needed with the latest new pll algo fixes.
- also don't use lcd pll limits.  They don't seem
to work well for all systems.  If we have a case where
they are useful, we can set the flag for that case.

Subject: drm/radeon/kms: avoid possible oops (call gart_fini before
 gart_disable)

radeon_gart_fini might call GART unbind callback function which
might try to access GART table but if gart_disable is call first
the GART table will be unmapped so any access to it will oops.

When there is allocation failure in radeon_cs_parser_relocs parser->nrelocs
is not cleaned. This causes NULL pointer defeference in radeon_cs_parser_fini
when clean up code is trying to loop over the relocation array and free the
objects.

Fix adds a check for a possible NULL pointer in clean up code.

Subject: drm: Return ENODEV if the inode mapping changes

Replace a BUG_ON with an error code in the event that the inode mapping
changes between calls to drm_open. This may happen for instance if udev
is loaded subsequent to the original opening of the device:

Subject: drm/radeon/r6xx/r7xx: CS parser fixes

- Drop some more safe regs taht userspace shouldn't hit
- Constant base regs need relocs.  This allows us to use
constant buffers rather than the constant register file.
Also we don't want userspace to be able to set arbitrary
mc base values for the const caches.
- Track SQ_CONFIG so we know whether userspace is using
the cfile or constant buffers.

Subject: drm/radeon/kms: minor fixes for eDP with LCD* device tags (v2)

Some systems have LCD* rather than DFP* device tags in the bios
for eDP connectors; notably the new apple iMac. This fixes
things up so eDP connectors with either tag will work.

v2: fix typo

Subject: drm/radeon/kms: display watermark updates (v2)

- Add module option to force the display priority
  0 = auto, 1 = normal, 2 = high
- Default to high on r3xx/r4xx/rv515 chips
  Fixes flickering problems during heavy acceleration
  due to underflow to the display controllers
- Fill in minimal support for RS600

v2 - update display priority when bandwidth is updated
so the user can change the parameter at runtime and it
will take affect on the next modeset.

Subject: drm/radeon/kms: use new pre/post_xfer i2c bit algo hooks

This allows us to remove the internal bit algo bus used by
the radeon i2c algo.  We now register a radeon algo adapter
if the gpio line is hw capable and the hw inplementation is
available, otherwise we register a bit algo adapter.

Subject: drm/radeon/kms: add hw_i2c module option

Turn off hw i2c by default except for mm i2c which
is hw only until we sort out the remaining prescale
issues on older chips.  hw i2c can be enabled with
hw_i2c=1.

Subject: drm/radeon/kms: add sanity check to wptr.

If we resume in a bad way, we'll get 0xffffffff in wptr, and then
oops with no console. This just adds a sanity check so that we can
avoid the oops and hopefully get more details out of people's systems.
