Daniel Vetter 446f8d81ca drm/i915: Don't try to tear down the stolen drm_mm if it's not there
Every other place properly checks whether we've managed to set
up the stolen allocator at boot-up properly, with the exception
of the cleanup code. Which results in an ugly

*ERROR* Memory manager not clean. Delaying takedown

at module unload time since the drm_mm isn't initialized at all.

v2: While at it check whether the stolen drm_mm is initialized instead
of the more obscure stolen_base == 0 check.

v3: Fix up the logic. Also we need to keep the stolen_base check in
i915_gem_object_create_stolen_for_preallocated since that can be
called before stolen memory is fully set up. Spotted by Chris Wilson.

v4: Readd the conversion in i915_gem_object_create_stolen_for_preallocated,
the check is for the dev_priv->mm.gtt_space drm_mm, the stolen
allocatot must already be initialized when calling that function (if
we indeed have stolen memory).

Chris Wilson baf27f9b17 drm/i915: Break up the large vsnprintf() in print_error_buffers()
So it appears that I have encountered some bogosity when trying to call
i915_error_printf() with many arguments from print_error_buffers(). The
symptom is that the vsnprintf parser tries to interpret an integer arg
as a character string, the resulting OOPS indicating stack corruption.
Replacing the single call with its 13 format specifiers and arguments
with multiple calls to i915_error_printf() worked fine. This patch goes
one step further and introduced i915_error_puts() to pass the strings
simply.

It may not fix the root cause, but it does prevent my box from dying and
I think helps make print_error_buffers() more friendly.

Chris Wilson d26e3af842 drm/i915: Refactor the wait_rendering completion into a common routine
Harmonise the completion logic between the non-blocking and normal
wait_rendering paths, and move that logic into a common function.

In the process, we note that the last_write_seqno is by definition the
earlier of the two read/write seqnos and so all successful waits will
have passed the last_write_seqno. Therefore we can unconditionally clear
the write seqno and its domains in the completion logic.

v2: Add the missing ring parameter, because sometimes it is good to have
things compile.

In the introduction of the non-blocking wait, I cut'n'pasted the wait

that the normal path returned early if the wait returned early. The
result is that read-only waits may return whilst the GPU is still

Daniel Vetter b5ea2d5681 drm/i915: fix hpd interrupt register locking
Our interrupt handler (in hardirq context) could race with the timer
(in softirq context), hence we need to hold the spinlock around the
call to ->hdp_irq_setup in intel_hpd_irq_handler, too.

But as an optimization (and more so to clarify things) we don't need
to do the irqsave/restore dance in the hardirq context.

Note also that on ilk+ the race isn't just against the hotplug
reenable timer, but also against the fifo underrun reporting. That one
also modifies the SDEIMR register (again protected by the same
dev_priv->irq_lock).

To lock things down again sprinkle a assert_spin_locked. But exclude
the functions touching SDEIMR for now, I want to extract them all into
a new helper function (like we do already for pipestate, display
interrupts and all the various gt interrupts).

v2: Add the missing 't' Egbert spotted in a comment.

v3: Actually fix the right misspelled comment (Paulo).

Daniel Vetter 6005ce4243 drm/i915: close tiny race in the ilk pcu even interrupt setup
By the time we write DEIER in the postinstall hook the interrupt
handler could run any time. And it does modify DEIER to handle
interrupts.

Hence the DEIER read-modify-write cycle for enabling the PCU event
source is racy. Close this races the same way we handle vblank
interrupts: Unconditionally enable the interrupt in the IER register,
but conditionally mask it in IMR. The later poses no such race since
the interrupt handler does not touch DEIMR.

Also update the comment, the clearing has already happened
unconditionally above.

Daniel Vetter 4bc9d43015 drm/i915: fix locking around ironlake_enable|disable_display_irq
The haswell unclaimed register handling code forgot to take the
spinlock. Since this is in the context of the non-rentrant interupt
handler and we only have one interrupt handler it is sufficient to
just grab the spinlock - we do not need to exclude any other
interrupts from running on the same cpu.

To prevent such gaffles in the future sprinkle assert_spin_locked over
these functions. Unfornately this requires us to hold the spinlock in
the ironlake postinstall hook where it is not strictly required:
Currently that is run in single-threaded context and with userspace
exlcuded from running concurrent ioctls. Add a comment explaining
this.

v2: ivb_can_enable_err_int also needs to be protected by the spinlock.
To ensure this won't happen in the future again also sprinkle a
spinlock assert in there.

Ben Widawsky a0de80a0e0 drm/i915: Fix context sizes on HSW
With updates to the spec, we can actually see the context layout, and
how many dwords are allocated. That table suggests we need 70720 bytes
per HW context. Rounded up, this is 18 pages. Looking at what lives
after the current 4 pages we use, I can't see too much important (mostly
it's d3d related), but there are a couple of things which look scary. I
am hopeful this can explain some of our odd HSW failures.

v2: Make the context only 17 pages. The power context space isn't used
ever, and execlists aren't used in our driver, making the actual total
66944 bytes.

It seems that even though Punit reports the frequency change to have

So rather than polling for Punit to complete the frequency change after

This also lets us continue working while Punit is performing the actual

fps is increased by ~5 fps, and the slowest frame duration is reduced
by ~25%.

The sysfs cur_freq file always reads the current frequency from Punit
anyway, so having rps.cur_delay be slightly off at times doesn't matter.

Chris Wilson a35cdaa0e1 drm/i915: Detect invalid scanout pitches
Report back the user error of attempting to setup a CRTC with an invalid
framebuffer pitch. This is trickier than it should be as on gen4, there
is a restriction that tiled surfaces must have a stride less than 16k -
which is less than the largest supported CRTC size.

v2: Fix the limits for gen3
v3: Move check into intel_framebuffer_init() and fix VLV limits. (vsyrjala)

Konrad Rzeszutek Wilk 1625e7e549 drm/i915: make compact dma scatter lists creation work with SWIOTLB backend.
Git commit 90797e6d1e
("drm/i915: create compact dma scatter lists for gem objects") makes
certain assumptions about the under laying DMA API that are not always
correct.

On a ThinkPad X230 with an Intel HD 4000 with Xen during the bootup
I see:

[drm:intel_pipe_set_base] *ERROR* pin & fence failed
[drm:intel_crtc_set_config] *ERROR* failed to set mode on [CRTC:3], err = -28

Bit of debugging traced it down to dma_map_sg failing (in
i915_gem_gtt_prepare_object) as some of the SG entries were huge (3MB).

That unfortunately are sizes that the SWIOTLB is incapable of handling -
the maximum it can handle is a an entry of 512KB of virtual contiguous
memory for its bounce buffer. (See IO_TLB_SEGSIZE).

Previous to the above mention git commit the SG entries were of 4KB, and
the code introduced by above git commit squashed the CPU contiguous PFNs
in one big virtual address provided to DMA API.

This patch is a simple semi-revert - were we emulate the old behavior
if we detect that SWIOTLB is online. If it is not online then we continue
on with the new compact scatter gather mechanism.

An alternative solution would be for the the '.get_pages' and the
i915_gem_gtt_prepare_object to retry with smaller max gap of the
amount of PFNs that can be combined together - but with this issue
discovered during rc7 that might be too risky.

Paulo Zanoni 15b1d171d8 drm/i915: fix the "ghost eDP" encoder unwind path
Because calling intel_dp_encoder_destroy inside
intel_edp_init_connector is just wrong. This is the initialization
path, so we should properly unwind all the initialization through the
whole caller stack.

On the intel_dp_encoder_destroy function we do the following:
1 - Call i2c_del_adapter
2 - Call drm_encoder_cleanup
3 - If edp:
3.1 - Cancel panel_vdd_work
3.2 - Call ironlake_panel_vdd_of_sync
4 - Free the encoder

And here is how we unwind each specific step:
1 - We have intel_dp_init_connector -> intel_dp_i2c_init ->
    i2c_dp_aux_add_bus -> i2c_add_adapter, so we call
    i2c_del_dapter at intel_dp_init_connector
2 - Call it in the same function that called drm_encoder_init
3 - Call it in the same function that called INIT_DELAYED_WORK
4 - Free it in the same function that allocated it

On the intel_dp_destroy function we do the following:
1 - Free edid if it exists
2 - Call intel_panel_fini in case it's eDP
3 - Call drm_sysfs_connector_remove
4 - Call drm_connector_cleanup
5 - Free the connector

And here is how we unwind each specific step:
1 - No need as we still didn't assign anything
2 - No need as we still didn't call intel_panel_init
3 - Call it in the same function that called drm_sysfs_connector_add
4 - Call it in the same function that called drm_connector_init
5 - Free it in the same function that allocated it

Paulo Zanoni 16c255335b drm/i915: propagate errors from intel_dp_init_connector
In case we detect a "ghost eDP", intel_edp_init_connector frees both
the connector and encoder and then returns. On Haswell, intel_ddi_init
then tries to use the freed encoder on the HDMI initialization path
since the following commit:

    drm/i915: don't setup hdmi for port D edp in ddi_init

So now on intel_ddi_init we check for the "ghost eDP" case and return
without trying to initialize HDMI. This way we won't try to read the
freed "intel_encoder" struct in the next "if" statement.

Paulo Zanoni acd8db100e drm/i915: don't check encoder at DP connector destroy()
By the time we call intel_dp_destroy (which destroys the connector)
the encoder may have been destroyed already, so if we use it we may be
reading some free memory. That happens in drm_mode_config_cleanup()
and also inside intel_dp_init_connector() when we detect a ghost eDP.

I also hope this may solve some random memory bugs.

This was rearming the workqueue with a 0 timeout, causing
a WARN_ON, and possible loop.

Daniel writes:
"I've looked a bit into this and I think we need to have a separate
work struct for recovering these lost hotplug events since the
continuous self-rearming case is a real risk (e.g. if a connector
flip-flops all the time). At least I don't see a sane way to block out
re-arming with the current code in a simple way. So reverting the
offender seems like the right thing and I'll go back to the drawing
