New Isochronous Priority Control (IPC) capability is introduced in newer
GEN platforms. This patch adds a device info flag to indicate if platform
supports IPC. Patch also sets this flag in supported platforms.

The original gen4 has an issue where writes (both render and blt) into
snoopable pages are lost. We've previously worked around this in
userspace (ddx, igt) by simply not requesting snoopable buffers, but upon
rediscovering this problem for a third time, make the kernel reject such
requests with -ENODEV.
This disables snooping on userspace buffers for i965g and i965gm (original
gen4) machines.

The corruption in CSB mmio reads we were seeing has been tracked down to
incorrectly touching forcewake of all domains, following an engine reset.
It is still a mistery why we only catched this in Broxton, since it
could happen in any platform.
With that fix already merged, commit 4055dc75d6 ("drm/i915: Stop
touching forcewake following a gen6+ engine reset"), lets try to enable
per-engine resets in Broxton one more time.

This is a preparatory patch which modifies error handler to do per engine
hang recovery. The actual patch which implements this sequence follows
later in the series. The aim is to prepare existing recovery function to
adapt to this new function where applicable (which fails at this point
because core implementation is lacking) and continue recovery using legacy
full gpu reset.
A helper function is also added to query the availability of engine
reset. A subsequent patch will add the capability to query which type
of reset is present (engine -> full -> no-reset) via the get-param
ioctl.
It has been decided that the error events that are used to notify user of
reset will only be sent in case if full chip reset. In case of just
single (or multiple) engine resets, userspace won't be notified by these
events.
Note that this implementation of engine reset is for i915 directly
submitting to the ELSP, where the driver manages the hang detection,
recovery and resubmission. With GuC submission these tasks are shared
between driver and firmware; i915 will still responsible for detecting a
hang, and when it does it will have to request GuC to reset that Engine and
remind the firmware about the outstanding submissions. This will be
added in different patch.
v2: rebase, advertise engine reset availability in platform definition,
add note about GuC submission.
v3: s/*engine_reset*/*reset_engine*/. (Chris)
Handle reset as 2 level resets, by first going to engine only and fall
backing to full/chip reset as needed, i.e. reset_engine will need the
struct_mutex.
v4: Pass the engine mask to i915_reset. (Chris)
v5: Rebase, update selftests.
v6: Rebase, prepare for mutex-less reset engine.
v7: Pass reset_engine mask as a function parameter, and iterate over the
engine mask for reset_engine. (Chris)
v8: Use i915.reset >=2 in has_reset_engine; remove redundant reset
logging; add a reset-engine-in-progress flag to prevent concurrent
resets, and avoid dual purposing of reset-backoff. (Chris)
v9: Support reset of different engines in parallel (Chris)
v10: Handle reset-engine flag locking better (Chris)
v11: Squash in reporting of per-engine-reset availability.

Some pieces of code are independent of hardware but are very tricky to
exercise through the normal userspace ABI or via debugfs hooks. Being
able to create mock unit tests and execute them through CI is vital.
Start by adding a central point where we can execute unit tests and
a parameter to enable them. This is disabled by default as the
expectation is that these tests will occasionally explode.
To facilitate integration with igt, any parameter beginning with
i915.igt__ is interpreted as a subtest executable independently via
igt/drv_selftest.
Two classes of selftests are recognised: mock unit tests and integration
tests. Mock unit tests are run as soon as the module is loaded, before
the device is probed. At that point there is no driver instantiated and
all hw interactions must be "mocked". This is very useful for writing
universal tests to exercise code not typically run on a broad range of
architectures. Alternatively, you can hook into the live selftests and
run when the device has been instantiated - hw interactions are real.
v2: Add a macro for compiling conditional code for mock objects inside
real objects.
v3: Differentiate between mock unit tests and late integration test.
v4: List the tests in natural order, use igt to sort after modparam.
v5: s/late/live/
v6: s/unsigned long/unsigned int/
v7: Use igt_ prefixes for long helpers.

Back in 2014, commit fb7023e0e2 ("drm/i915: BDW: Adding Reserved PCI
IDs.") added the reserved PCI IDs in order to try to make sure we had
working drivers in case we ever released products using these IDs
(since we had instances of this type of problem in the past). The
problem is that the patch only touched the macros used by
early-quirks.c and by the user space components that rely on
i915_pciids.h, it didn't touch the macros used by i915_pci.c. So we
correctly handled the stolen memory for these theoretical IDs, but we
didn't actually drive the devices from i915.ko.
So this patch fixes the original commit by actually making i915.ko
drive these IDs, which was the goal. There's no information on what
would be the GT count on these IDs, so we just go with the safer
intel_broadwell_info, at the risk of ignoring a possibly inexistent
BSD2_RING.
I did some checking, and it seems that these IDs are driven by
intel-gpu-tools, xf86-video-intel and libdrm (since they contain old
copies of i915_pciids.h), but they are not checked by mesa.
The alternative to this patch would be to just assume we're actually
never going to use these IDs, and then remove them from our ID lists
and make sure our user space components sync the latest i915_pciids.h
copy. I'm fine with either approaches, as long as we make sure that
every component tries to drive the same list of PCI IDs.

Decoupled MMIO is an alternative way to access forcewake domain
registers, which requires less cycles for a single read/write and
avoids frequent software forcewake.
This certainly gives advantage over the forcewake as this new
mechanism “decouples” CPU cycles and allow them to complete even
when GT is in a CPD (frequency change) or C6 state.
This can co-exist with forcewake and we will continue to use forcewake
as appropriate. E.g. 64-bit register writes to avoid writing 2 dwords
separately and land into funny situations.

The term "preliminary hardware support" has always caused confusion both
among users and developers. It has always been about preliminary driver
support for new hardware, and not so much about preliminary hardware. Of
course, initially both the software and hardware are in early stages,
but the distinction becomes more clear when the user picks up production
hardware and an older kernel to go with it, with just the early support
we had for the hardware at the time the kernel was released. The user
has to specifically enable the alpha quality *driver* support for the
hardware in that specific kernel version.
Rename preliminary_hw_support to alpha_support to emphasize that the
module parameter, config option, and flag are about software, not about
hardware. Improve the language in help texts and debug logging as well.
This appears to be a good time to do the change, as there are currently
no platforms with preliminary^W alpha support.
