drm/panfrost: Add basic support for speed binning
Some SoCs implementing ARM Mali GPUs are subject to speed binning:
this means that some versions of the same SoC model may need to be
limited to a slower frequency compared to the other:
this is being addressed by reading nvmem (usually, an eFuse array)
containing a number that identifies the speed binning of the chip,
which is usually related to silicon quality.
To address such situation, add basic support for reading the
speed-bin through nvmem, as to make it possible to specify the
supported hardware in the OPP table for GPUs.
This commit also keeps compatibility with any platform that does
not specify (and does not even support) speed-binning.

This series adds a deadline hint to fences, so realtime deadlines

This is partially inspired by a trick i915 does, but implemented

1) To continue to be able to use the atomic helpers
2) To support cases where display and gpu are different drivers
See https://patchwork.freedesktop.org/series/93035/
This does not yet add any UAPI, although this will be needed in
a number of cases:
1) Workloads "ping-ponging" between CPU and GPU, where we don't
want the GPU freq governor to interpret time stalled waiting
for GPU as "idle" time
2) Cases where the compositor is waiting for fences to be signaled
before issuing the atomic ioctl, for example to maintain 60fps
cursor updates even when the GPU is not able to maintain that
framerate.

drm: exynos: dsi: Lookup OF-graph or Child node devices
In general, for MIPI DSI there are three ways to represent the
pipeline for an upstream bridge to find the connected downstream
panel or bridge.
1. Child panel or bridge as a conventional device tree child node.
2. Child panel or bridge as an OF-graph port node.
3. Child panel or bridge as an OF-graph ports node.
There are three different downstream panels or bridges that are
possible to connect an upstream DSI host bridge - DSI Panel,
DSI Bridge, and I2C-Configured DSI bridge.
An example of the downstream panel represented as a child node,
&dsi {
compatible = "samsung,exynos5433-mipi-dsi";
ports {
port@0 {
reg = <0>;
dsi_to_mic: endpoint {
remote-endpoint = <&mic_to_dsi>;
};
};
};
panel@0 {
reg = <0>;
};
};
An example of the downstream bridge represented as a port node,
&i2c4 {
bridge@2c {
compatible = "ti,sn65dsi84";
ports {
port@0 {
reg = <0>;
bridge_in_dsi: endpoint {
remote-endpoint = <&dsi_out_bridge>;
data-lanes = <1 2>;
};
};
port@2 {
reg = <2>;
bridge_out_panel: endpoint {
remote-endpoint = <&panel_out_bridge>;
};
};
};
};
};
&dsi {
compatible = "fsl,imx8mm-mipi-dsim";
port {
dsi_in_lcdif: endpoint@0 {
reg = <0>;
remote-endpoint = <&lcdif_out_dsi>;
};
dsi_out_bridge: endpoint@1 {
reg = <1>;
remote-endpoint = <&bridge_in_dsi>;
};
};
};
An example of the downstream bridge represented as a ports node,
&dsi {
compatible = "fsl,imx8mm-mipi-dsim";
ports {
port@0 {
reg = <0>;
dsi_in_lcdif: endpoint@0 {
reg = <0>;
remote-endpoint = <&lcdif_out_dsi>;
};
};
port@1 {
reg = <1>;
dsi_out_bridge: endpoint {
remote-endpoint = <&bridge_in_dsi>;
};
};
};
In, summary it is possible to represent all three downstream slaves
devices using OF-graph port or ports node however only DSI Panel and
DSI Bridge are possible but not possible to represent I2C-Configured
DSI bridge child nodes since I2C-Configure bridges are child of I2C
node, not upstream DSI host bridge and it is must represent them
endpoint port linking.
This indeed means, the OF-graph port or ports representation is
mandatory for I2C-Configured DSI bridges.
This patch tries to add an OF-graph port or ports representation
detection code on top of existing child node detection.
It is possible to replace the entire detection code using existing
drm_of helper drm_of_find_panel_or_bridge but it will break the
Exynos DSI since the pipeline doesn't support OF-graph port or ports
node.
Overall, this patch has a combination of child and OF-graph pipeline
detections in order to support the backward compatibility of Exynos
DSI child node and i.MX8M Mini/Nano/Plus OF-graph port or ports
node pipelines.
This is the first common DSI host bridge driver that needs to support
all possible downstream connection pipeline combinations.

drm: rcar-du: Write correct values in DORCR reserved fields
The DORCR register controls the routing of clocks and data between DU
channels within a group. For groups that contain a single channel,
there's no routing option to control, and some fields of the register
are then reserved. On Gen2 those reserved fields are documented as
required to be set to 0, while on Gen3 and newer the PG1T, DK1S and PG1D
reserved fields must be set to 1.
The DU driver initializes the DORCR register in rcar_du_group_setup(),
where it ignores the PG1T, DK1S and PG1D, and then configures those
fields to the correct value in rcar_du_group_set_routing(). This hasn't
been shown to cause any issue, but prevents certifying that the driver
complies with the documentation in safety-critical use cases.
As there is no reasonable change that the documentation will be updated
to clarify that those reserved fields can be written to 0 temporarily
before starting the hardware, make sure that the registers are always
set to valid values.

drm: rcar-du: lvds: Fix LVDS PLL disable on D3/E3
On R-Car D3 and E3, the LVDS encoder provides the dot (pixel) clock to
the DU, regardless of whether the LVDS output is used or not. When using
the DPAD (RGB) output, the DU driver thus enables and disables the LVDS
PLL manually, while when using the LVDS output, it lets the LVDS bridge
driver handle the PLL configuration internally as part of the atomic
enable and disable operations.
This causes an issue when using the LVDS output. As bridges are disabled
before CRTCs, the current implementation violates the enable/disable
sequences documented in the hardware datasheet, which requires the dot
clock to be enabled before the CRTC is started and disabled after it
gets stopped.
Fix the problem by enabling/disabling the LVDS PLL manually from the DU
regardless of which output is used, and skipping the PLL handling in the
LVDS bridge atomic enable and disable operations.
This is however not enough. Disabling the LVDS encoder while leaving the
PLL on still results in a vertical blanking wait timeout when disabling
the DU. Investigation showed that the culprit is the LVEN bit. For an
unclear reason, clearing the bit when disabling the LVDS encoder blocks
vertical blanking interrupts. We thus have to delay disabling the whole
LVDS encoder, not just disabling the PLL, until the DU is disabled.
We could split the LVDS disable sequence by clearing the LVRES bit in
the LVDS bridge atomic disable handler, and delaying the rest of the
operations, in order to disable the LVDS output at bridge atomic disable
time, before stopping the CRTC. This would make the code more complex,
without a clear benefit, so keep the implementation simple(r).

smb3: fix unusable share after force unmount failure
If user does forced unmount ("umount -f") while files are still open
on the share (as was seen in a Kubernetes example running on SMB3.1.1
mount) then we were marking the share as "TID_EXITING" in umount_begin()
which caused all subsequent operations (except write) to fail ... but
unfortunately when umount_begin() is called we do not know yet that
there are open files or active references on the share that would prevent
unmount from succeeding. Kubernetes had example when they were doing
umount -f when files were open which caused the share to become
unusable until the files were closed (and the umount retried).
Fix this so that TID_EXITING is not set until we are about to send
the tree disconnect (not at the beginning of forced umounts in
umount_begin) so that if "umount -f" fails (due to open files or
references) the mount is still usable.

cifs: fix dentry lookups in directory handle cache
Get rid of any prefix paths in @path before lookup_positive_unlocked()
as it will call ->lookup() which already adds those prefix paths
through build_path_from_dentry().
This has caused a performance regression when mounting shares with a
prefix path where readdir(2) would end up retrying several times to
open bad directory names that contained duplicate prefix paths.
Fix this by skipping any prefix paths in @path before calling
lookup_positive_unlocked().

smb3: lower default deferred close timeout to address perf regression
Performance tests with large number of threads noted that the change
of the default closetimeo (deferred close timeout between when
close is done by application and when client has to send the close
to the server), to 5 seconds from 1 second, significantly degraded
perf in some cases like this (in the filebench example reported,
the stats show close requests on the wire taking twice as long,
and 50% regression in filebench perf). This is stil configurable
via mount parm closetimeo, but to be safe, decrease default back
to its previous value of 1 second.
