MIPS will soon not be a part of Imagination Technologies, and as such
many @imgtec.com email addresses will no longer be valid. This patch
updates the addresses for those who:
- Have 10 or more patches in mainline authored using an @imgtec.com
email address, or any patches dated within the past year.
- Are still with Imagination but leaving as part of the MIPS business
unit, as determined from an internal email address list.
- Haven't already updated their email address (ie. JamesH) or expressed
a desire to be excluded (ie. Maciej).
- Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt &
myself.
New addresses are of the form firstname.lastname@mips.com, and all
verified against an internal email address list. An entry is added to
.mailmap for each person such that get_maintainer.pl will report the new
addresses rather than @imgtec.com addresses which will soon be dead.
Instances of the affected addresses throughout the tree are then
mechanically replaced with the new @mips.com address.

Pull initial SPDX identifiers from Greg KH:
"License cleanup: add SPDX license identifiers to some files
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the
'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally
binding shorthand, which can be used instead of the full boiler plate
text.
This patch is based on work done by Thomas Gleixner and Kate Stewart
and Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset
of the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to
license had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied
to a file was done in a spreadsheet of side by side results from of
the output of two independent scanners (ScanCode & Windriver)
producing SPDX tag:value files created by Philippe Ombredanne.
Philippe prepared the base worksheet, and did an initial spot review
of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537
files assessed. Kate Stewart did a file by file comparison of the
scanner results in the spreadsheet to determine which SPDX license
identifier(s) to be applied to the file. She confirmed any
determination that was not immediately clear with lawyers working with
the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained
>5 lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that
was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that
became the concluded license(s).
- when there was disagreement between the two scanners (one detected
a license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply
(and which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases,
confirmation by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.
The Windriver scanner is based on an older version of FOSSology in
part, so they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot
checks in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect
the correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial
patch version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch
license was not GPL-2.0 WITH Linux-syscall-note to ensure that the
applied SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

In case the object has changed tiling between calls to execbuf, we need
to check if the existing offset inside the GTT matches the new tiling
constraint. We even need to do this for "unfenced" tiled objects, where
the 3D commands use an implied fence and so the object still needs to
match the physical fence restrictions on alignment (only required for
gen2 and early gen3).
In commit 2889caa92321 ("drm/i915: Eliminate lots of iterations over
the execobjects array"), the idea was to remove the second guessing and
only set the NEEDS_MAP flag when required. However, the entire check
for an unusable offset for fencing was removed and not just the
secondary check. I.e.
/* avoid costly ping-pong once a batch bo ended up non-mappable */
if (entry->flags & __EXEC_OBJECT_NEEDS_MAP &&
!i915_vma_is_map_and_fenceable(vma))
return !only_mappable_for_reloc(entry->flags);
was entirely removed as the ping-pong between execbuf passes was fixed,
but its primary purpose in forcing unaligned unfenced access to be
rebound was forgotten.

Just like the CTO timeout calculation introduced recently, the DTO
timeout calculation was incorrect. It used "bus_hz" but, as far as I
can tell, it's supposed to use the card clock. Let's account for the
div value, which is documented as 2x the value stored in the register,
or 1 if the register is 0.
NOTE: This was likely not terribly important until commit 16a34574c6ca
("mmc: dw_mmc: remove the quirks flags") landed because "DIV" is
documented on Rockchip SoCs (the ones that used to define the quirk)
to always be 0 or 1. ...and, in fact, it's documented to only be 1
with EMMC in 8-bit DDR52 mode. Thus before the quirk was applied to
everyone it was mostly OK to ignore the DIV value.
I haven't personally observed any problems that are fixed by this
patch but I also haven't tested this anywhere with a DIV other an 0.
AKA: this problem was found simply by code inspection and I have no
failing test cases that are fixed by it. Presumably this could fix
real bugs for someone out there, though.

The ASIC has the ability to generate events whenever a sensor indicates
the temperature goes above or below its high or low thresholds,
respectively.
In new firmware versions the firmware enforces a minimum of 5
degrees Celsius difference between both thresholds. Make the driver
conform to this requirement.
Note that this is required even when the events are disabled, as in
certain systems interrupts are generated via GPIO based on these
thresholds.

The function of_parse_phandle() returns a NULL pointer if it cannot
resolve a phandle property to a device_node pointer. In function
hns_nic_dev_probe(), its return value is passed to PTR_ERR to extract
the error code. However, in this case, the extracted error code will
always be zero, which is unexpected.

The fix 5987feb38aa5 ("net: phy: marvell: logical vs bitwise OR typo")
uncovered another bug in the Marvell PHY driver, which broke the
Marvell OpenRD platform. It relies on the bootloader configuring the
RGMII delays and does not specify a phy-mode in its device tree. The
PHY driver should only configure RGMII delays if the phy mode
indicates it is using RGMII. Without anything in device tree, the
mv643xx Ethernet driver defaults to GMII.

On error, kthread_create() returns an errno-encoded pointer, not NULL.
The routine qla2x00_probe_one() detects the error case and jumps to
probe_failed, but has already assigned the return value from
kthread_create() to ha->dpc_thread. Then probe_failed checks to see if
ha->dpc_thread is not NULL before doing cleanup on it. Since in the
error case this is also not NULL, it ends up trying to access an invalid
task pointer.
Solution is to assign NULL to ha->dpc_thread in the error path to avoid
kthread cleanup in that case.

Per my reading of the eDP spec, DP_DPCD_DISPLAY_CONTROL_CAPABLE bit in
DP_EDP_CONFIGURATION_CAP should be set if the eDP display control
registers starting at offset DP_EDP_DPCD_REV are "enabled". Currently we
check the bit before reading the registers, and DP_EDP_DPCD_REV is the
only way to detect eDP revision.
Turns out there are (likely buggy) displays that require eDP 1.4+
features, such as supported link rates and link rate select, but do not
have the bit set. Read the display control registers
unconditionally. They are supposed to read zero anyway if they are not
supported, so there should be no harm in this.
This fixes the referenced bug by enabling the eDP version check, and
thus reading of the supported link rates. The panel in question has 0 in
DP_MAX_LINK_RATE which is only supported in eDP 1.4+. Without the
supported link rates method we default to RBR which is insufficient for
the panel native mode. As a curiosity, the panel also has a bogus value
of 0x12 in DP_EDP_DPCD_REV, but that passes our check for >= DP_EDP_14
(which is 0x03).

The original intent was to preserve watermarks as much as possible
in intel_pipe_wm.raw_wm, and put the validated ones in intel_pipe_wm.wm.
It seems this approach is insufficient and we don't always preserve
the raw watermarks, so just use the atomic iterator we're already using
to get a const pointer to all bound planes on the crtc.

During modeset cleanup on driver unload we may have a pending
hotplug work. This needs to be canceled early during the teardown
so that it does not fire after we have freed the connector.
We do this after drm_kms_helper_poll_fini(dev) since this might
trigger modeset retry work due to link retrain and before
intel_fbdev_fini() since this work requires the lock from fbdev.
If this is not done we may see something like:

This attempts to instill a bit of paranoia to the code dealing with
the CTO timer. It's believed that this will make the CTO timer more
robust in the case that we're having very long interrupt latencies.
Note that I originally thought that perhaps this patch was being
overly paranoid and wasn't really needed, but then while I was running
mmc_test on an rk3399 board I saw one instance of the message:
dwmmc_rockchip fe320000.dwmmc: Unexpected interrupt latency
I had debug prints in the CTO timer code and I found that it was
running CMD 13 at the time.
...so even though this patch seems like it might be overly paranoid,
maybe it really isn't?
Presumably the bad interrupt latency experienced was due to the fact
that I had serial console enabled as serial console is typically where
I place blame when I see absurdly large interrupt latencies. In this
particular case there was an (unrelated) printout to the serial
console just before I saw the "Unexpected interrupt latency" printout.
...and actually, I managed to even reproduce the problems by running
"iw mlan0 scan > /dev/null" while mmc_test was running. That not only
does a bunch of PCIe traffic but it also (on my system) outputs some
SELinux log spam.

In the commit 03de19212ea3 ("mmc: dw_mmc: introduce timer for broken
command transfer over scheme") we tried to calculate the expected
hardware command timeout value. Unfortunately that calculation isn't
quite correct in all cases. It used "bus_hz" but, as far as I can
tell, it's supposed to use the card clock. Let's account for the div
value, which is documented as 2x the value stored in the register, or
1 if the register is 0.
NOTE: It's not expected that this will actually fix anything important
since the 10 ms margin added by the function will pretty much dwarf
any calculations. The card clock should be 100 kHz at minimum and:
1000 ms/s * (255 * 2) / 100000 Hz.
Gives us 5.1 ms.
...so really the point of this patch is just to make the code more
"correct" in case anyone ever tries to remove the 10 ms buffer.

When running with the commit 03de19212ea3 ("mmc: dw_mmc: introduce

in the log:
Unexpected command timeout, state 7
It turns out that we weren't properly cancelling the new CTO timer in
the case that a voltage switch was done. Let's promote the cancel
into the dw_mci_cmd_interrupt() function to fix this.

Thorsten reported on <fa6e3ee2-91b5-a54b-afe3-87f30aac7a48@leemhuis.info> that
commit c9353bf483d3 made ath10k unstable with QCA6174 on his Dell XPS13 (9360)
with an error message:
ath10k_pci 0000:3a:00.0: failed to extract amsdu: -11
It only seemed to happen with certain APs, not all, but when it happened the
only way to get ath10k working was to switch the wifi off and on with a hotkey.
As this commit made things even worse (a warning vs breaking the whole
connection) let's revert the commit for now and while the issue is being fixed.

Rx data frames notified through HTT_T2H_MSG_TYPE_RX_IND and
HTT_T2H_MSG_TYPE_RX_FRAG_IND expect PN/TSC check to be done
on host (mac80211) rather than firmware. Rebuild cipher header
in every received data frames (that are notified through those
HTT interfaces) from the rx_hdr_status tlv available in the
rx descriptor of the first msdu. Skip setting RX_FLAG_IV_STRIPPED
flag for the packets which requires mac80211 PN/TSC check support
and set appropriate RX_FLAG for stripped crypto tail. Hw QCA988X,
QCA9887, QCA99X0, QCA9984, QCA9888 and QCA4019 currently need the
rebuilding of cipher header to perform PN/TSC check for replay

Please note that removing crypto tail for CCMP-256, GCMP and GCMP-256 ciphers
in raw mode needs to be fixed. Since Rx with these ciphers in raw
mode does not work in the current form even without this patch and
removing crypto tail for these chipers needs clean up, raw mode related
issues in CCMP-256, GCMP and GCMP-256 can be addressed in follow up
patches.
