303dad15ed habanalabs: remove support to export dmabuf from handle
The API to the user which allows exporting DMA buffer from handle is
deprecated here. It was never used as it is relevant only for Gaudi2,
and the user stack has yet to add support for dmabuf in Gaudi2.

Looking forward, a modified API to export DMA buffer for ASICs that
supports virtual memory will be added.

Until the new API will be ready- exporting DMA buffer will not be
supported for ASICs with virtual memory.

811c74baed habanalabs: define traces for COMMS protocol
As the COMMS protocol is being used more widely in our driver,
an available debug tool for the handshake will be handy.

This commit defines tracepoints to various key points of the COMMS
protocol.

b219d209ab habanalabs/gaudi2: support abrupt device reset event
In certain scenarios, firmware might encounter a fatal event for
which a device reset is required. Hence, a proper notification
is needed for driver to be aware and initiate a reset sequence.

In secured environments the reset will be performed by firmware
without an explicit request from the driver.

086ab54ac0 habanalabs: skip device idle check in hpriv_release if in reset
When user context is released and hpriv_release() is called, there is a
device idle status check, to understand if user has left the device not
idle and then a reset is required.

However, if the user process is killed because of device hard reset,
the device at this point would always be not idle, because the device
engines were already forcefully halted.

Modify hpriv_release() to skip the idle check if reset is in progress.

6003cb46e6 habanalabs: don't allow user to destroy CB handle more than once
The refcount of a CB buffer is initialized when user allocates a CB,
and is decreased when he destroys the CB handle.

If this refcount is increased also from kernel and user sends more than
one destroy requests for the handle, the buffer will be released/freed
and later be accessed when the refcount is put from kernel side.

To avoid it, prevent user from destroying the handle more than once.

ce259804d2 habanalabs: abort waiting user threads upon error
User should close the FD when being notified about an error, after
which a device reset takes place.

However, if the user has pending threads that wait for completions,
the device release won't be called and eventually the watchdog timeout
will expire, leading to hard reset and killing the user process.

To avoid it, abort such waiting threads right after the error
notification, and block following waiting operations.

This seems to be a false positive in my opinion but still we can silence
the tool while making the code easier to read. Let's also add a comment,
to explain why the "com_seq" logical not is used rather than its value.

fa904b4cbc drm/simpledrm: Use struct iosys_map consistently
The majority of the driver already uses struct iosys_map to encapsulate
accesses to I/O remapped vs. system memory. Accesses via the screen base
pointer still use __iomem annotations, which can lead to inconsistencies
and conflicts with subsequent patches.

Convert the screen base to a struct iosys_map as well for consistency
and to avoid these issues.

c533b5167c drm/edid: add separate drm_edid_connector_add_modes()
The original goal with drm_edid_connector_update() was to have a single
call for updating the connector and adding probed modes, in this order,
but that turned out to be problematic. Drivers that need to update the
connector in the .detect() callback would end up updating the probed
modes as well. Turns out the callback may be called so many times that
the probed mode list fills up without bounds, and this is amplified by
add_alternate_cea_modes() duplicating the CEA modes on every call,
actually running out of memory on some machines.

Kudos to Imre Deak <imre.deak@intel.com> for explaining this to me.

Go back to having separate drm_edid_connector_update() and
drm_edid_connector_add_modes() calls. The former may be called from
.detect(), .force(), or .get_modes(), but the latter only from
.get_modes().

Unlike drm_add_edid_modes(), have drm_edid_connector_add_modes() update
the probed modes from the EDID property instead of the passed in
EDID. This is mainly to enforce two things:

1) drm_edid_connector_update() must be called before
   drm_edid_connector_add_modes().

   Display info and quirks are needed for parsing the modes, and we
   don't want to call update_display_info() again to ensure the info is
   available, like drm_add_edid_modes() does.

2) The same EDID is used for both updating the connector and adding the
   probed modes.

Fortunately, the change is easy, because no driver has actually adopted
drm_edid_connector_update(). Not even i915, and that's mainly because of
the problem described above.

919d320fb8 drm/edid: split HDMI VSDB info and mode parsing
Separate the parsing of display info and modes from the HDMI VSDB. This
is prerequisite work for overall better separation of the two parsing
steps.

The info parsing is about figuring out whether the sink supports HDMI
infoframes. Since they were added in HDMI 1.4, assume the sink supports
HDMI infoframes if it has the HDMI_Video_present bit set (introduced in
HDMI 1.4). For details, see commit f1781e9bb2 ("drm/edid: Allow HDMI
infoframe without VIC or S3D").

The logic is not exactly the same, but since it was somewhat heuristic
to begin with, assume this is close enough.

v2:
- Simplify to only check HDMI_Video_present bit (Ville)
- Drop cea_db_raw_size() helper (Ville)

2e337a8d14 drm: exynos: dsi: Properly name HSA/HBP/HFP/HSE bits
HSA/HBP/HFP/HSE mode bits in Processor Reference Manuals specify
a naming conversion as 'disable mode bit' due to its bit definition,
0 = Enable and 1 = Disable.

For HSE bit, the i.MX 8M Mini/Nano/Plus Applications Processor
Reference Manual named this bit as 'HseDisableMode' but the bit
definition is quite opposite like
0 = Disables transfer
1 = Enables transfer
which clearly states that HSE is not a disable bit.

HSE is named as per the manual even though it is not a disable
bit however the driver logic for handling HSE is based on the
MIPI_DSI_MODE_VIDEO_HSE flag itself.
