Merge tag 'drm-habanalabs-next-2023-10-10' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into drm-next
This tag contains habanalabs driver changes for v6.7.
The notable changes are:
- uAPI changes:
- Expose tsc clock sampling to better sync clock information in profiler.
- Enhance engine error reporting in the info ioctl.
- Block access to the eventfd operations through the control device.
- Disable the option of the user to register multiple times with the same
offset for timestamp dump by the driver. If a user wants to use the same
offset in the timestamp buffer for different interrupt, it needs to first
de-register the offset.
- When exporting dma-buf (for p2p), force the user to specify size/offset
in multiples of PAGE_SIZE. This is instead of the driver doing the
rounding to PAGE_SIZE, which has caused the driver to map more memory
than was intended by the user.
- New features and improvements:
- Complete the move of the driver to the accel subsystem by removing the
custom habanalabs class and major and registering to accel subsystem.
- Move the firmware interface files to include/linux/habanalabs. This is
a pre-requisite for upstreaming the NIC drivers of Gaudi (as they need to
include those files).
- Perform device hard-reset upon PCIe AXI drain event to prevent the failure
from cascading to different IP blocks in the SoC. In secured environments,
this is done automatically by the firmware.
- Print device name when it is removed for better debuggability.
- Add support for trace of dma map sgtable operations.
- Optimize handling of user interrupts by splitting the interrupts to two
lists. One list for fast handling and second list for handling with
timestamp recording, which is slower.
- Prevent double device hard-reset due to 2 adjacent H/W events.
- Set device status 'malfunction' while in rmmod.
- Firmware related fixes:
- Extend preboot timeout because preboot loading might take longer than
expected in certain cases.
- Add a protection mechanism for the Event Queue. In case it is full, the
firmware will be able to notify about it through a dedicated interrupt.
- Perform device hard-reset in case scrubbing of memory has failed.
- Bug fixes and code cleanups:
- Small fixes of dma-buf handling in Gaudi2, such as handling an offset != 0,
using the correct exported size, creation of sg table.
- Fix spmu mask creation.
- Fix bug in wait for cs completion for decoder workloads.
- Cleanup Greco name from documentation.
- Fix bug in recording timestamp during cs completion interrupt handling.
- Fix CoreSight ETF configuration and flush logic.
- Fix small bug in hpriv_list handling (the list that contains the private
data per process that opens our device).

drm/i915/vlv_dsi: Add DMI quirk for backlight control issues on Lenovo Yoga Tab 3 (v2)
On the Lenovo Yoga Tab 3 Pro YT3-X90F there are 2 issues with the backlight
on/off MIPI sequences:
1. The backlight on sequence has an I2C MIPI sequence element which uses
bus 0, but there is a bogus I2cSerialBus resource under the GPU in
the DSDT which causes i2c_acpi_find_adapter() to pick the wrong bus.
2. There is no backlight off sequence, causing the backlight to stay on.
Add a DMI quirk fixing both issues.
v2:

drm/i915/vlv_dsi: Add DMI quirk for wrong I2C bus and panel size on Lenovo Yoga Tablet 2 series (v3)
On the Lenovo Yoga Tablet 2 830 / 1050 there are 2 problems:
1. The I2C MIPI sequence elements reference bus 3. ACPI has I2C1 - I2C7
which under Linux become bus 0 - 6. And the MIPI sequence reference
to bus 3 is indented for I2C3 which is bus 2 under Linux.
This leads to errors like these:
[ 178.244049] i2c_designware 80860F41:03: controller timed out
[ 178.245703] i915 0000:00:02.0: [drm] *ERROR* Failed to xfer payload of size (1) to reg (169)
There are 3 timeouts when the panel is on, delaying
waking up the screen on a key press by 3 seconds.
Note mipi_exec_i2c() cannot just subtract 1 from the bus
given in the I2C MIPI sequence element. Since on other
devices the I2C bus-numbers used in the MIPI sequences do
actually start at 0.
2. width_/height_mm contain a bogus 192mm x 120mm size. This is
especially a problem on the 8" 830 version which uses a 10:16
portrait screen where as the bogus size is 16:10.
Add a DMI quirk to override the I2C bus and the panel size with
the correct values.
Note both the 10" 1050 models as well as the 8" 830 models use the same
mainboard and thus the same DMI strings. The 10" 1050 uses a 1920x1200
landscape screen, where as the 8" 830 uses a 1200x1920 portrait screen,
so the quirk handling uses the display resolution to detect the model.
v2:
- Also override i2c_bus_num to fix mipi_exec_i2c() timeouts
v3:
- Add Closes tag to gitlab issue with drm.debug=0xe, VBT info

drm/i915/vlv_dsi: Add DMI quirk for wrong panel modeline in BIOS on Asus TF103C (v3)
Vtotal is wrong in the BIOS supplied modeline for the DSI panel on
the Asus TF103C leading to the last line of the display being shown
as the first line.
The factory installed Android has a hardcoded modeline in its kernel,
causing it to not suffer from this BIOS bug;
and the Android boot-splash which uses the EFI FB which does have this bug
has the last line all black causing the bug to not be visible.
This commit introduces a generic DMI based quirk mechanism to vlv_dsi for
doing various fixups, and uses this to correct the modeline.
v2:
- s/mode_fixup/dmi_quirk/ to make the new DMI quirk mechanism more generic

drm: Replace drm_framebuffer plane size functions with its equivalents
The functions drm_framebuffer_plane_{width,height} and
fb_plane_{width,height} do exactly the same job of its
equivalents drm_format_info_plane_{width,height} from drm_fourcc.
The only reason to have these functions on drm_framebuffer
would be if they would added a abstraction layer to call it just
passing a drm_framebuffer pointer and the desired plane index,
which is not the case, where these functions actually implements
just part of it. In the actual implementation, every call to both
drm_framebuffer_plane_{width,height} and fb_plane_{width,height} should
pass some drm_framebuffer attribute, which is the same as calling the
drm_format_info_plane_{width,height} functions.
The drm_format_info_pane_{width,height} functions are much more
consistent in both its implementation and its location on code. The
kind of calculation that they do is intrinsically derivated from the
drm_format_info struct and has not to do with drm_framebuffer, except
by the potential motivation described above, which is still not a good
justification to have drm_framebuffer functions to calculate it.
So, replace each drm_framebuffer_plane_{width,height} and
fb_plane_{width,height} call to drm_format_info_plane_{width,height}
and remove them.

drm: Remove plane hsub/vsub alignment requirement for core helpers
The drm_format_info_plane_{height,width} functions was implemented using
regular division for the plane size calculation, which cause issues [1][2]
when used on contexts where the dimensions are misaligned with relation
to the subsampling factors. So, replace the regular division by the
DIV_ROUND_UP macro.
This allows these functions to be used in more drivers, making further
work to bring more core presence on them possible.

the file parameter from fb_pgprotect().
