MediaTek driver updates for v6.15
This adds entries for new and missing SoCs in the MediaTek SoCInfo driver (MT8370AV/AZA, MT8390AV/AZA) and an extra entry for a new revision of the MT8395AV/ZA SoC. The MediaTek SoCInfo driver also gets its SoC attribute information restructured: now the family, machine and soc_id fields are correctly populated. MT8188 gains support for the secondary Display Parallel Interface used for HDMI, and for the Display Stream Compression component routing through mmsys and mutex tables. All of the MMSYS drivers get an important overhaul: it was found that, in multiple cases, the tables contained wrong mask/value pairs, hence those were doing either nothing or breaking routings. The mmsys tables were converted to use a newly introduced macro that will perform a compile time check, making sure that each table entry's value fits in the declared register mask. Thanks to the new macro, multiple MediaTek SoCs got multiple fixes in their MMSYS tables, addressing issues that were severely impacting the functionality of the display controller pipelines. -----BEGIN PGP SIGNATURE----- iJ4EABYKAEYWIQQn3Xxr56ypAcSHzXSaNgTPrZeEeAUCZ8mA2CgcYW5nZWxvZ2lv YWNjaGluby5kZWxyZWdub0Bjb2xsYWJvcmEuY29tAAoJEJo2BM+tl4R4Vg4A/RwP qv6tZhnc0Y9fSygMAoSNhNcD62WBvxGI3VmmomS7AP9YmfRWBoiawv5PzT7x9myN 9dauqi3lC7AjUhZejNjvBQ== =YKqm -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmfJy68ACgkQYKtH/8kJ Uiey7w/+Pu25ynRxg3F6GLUwsBl6gQk5nxsuRsoVUcU80RtAIE6A8mmjLrTbrY4R wyaNN9JnVE7qN+MXN6hZZ6uYktr3TYGPTR/V9gO4Uc4RmPxxDJltypf4nMfr6q1Q e4qCScDpgT3728vzEhQxL1vGjOOZPx2CImVlt0q4RM0dDkLolsOW5L1MXGGt0Vb+ OX6QWVeeacIXcMFKYsXI9y52B3akv6bERkPMgnojT9FSoANT2A4R8H5RgtDyY85x c5nVqWBqylGYzGAcaUSWc4xTS6eTaGj7ua3rd1X3DLeeHhkXbLbrdQQrkRNNPWiY hzNdHi19Pz8u8T2bGHaJ1nLJDepLHh13hx3OtJ2h2uxcjUQ7GSKvkOCILVv0E0y2 upd6TLXqyQTpk8JwmWt3jQ91m7sfCqSzwq2X9xATFs7Fp+jVGpTA6cQgLWwxKa9+ r9FbKpxToiPAYvc/v6CYC8IlXIy+NWn2UjSBlltB2mQURHnWk2TuTvsCcllFrG+S tDQN9+auNDMLDP+TIbWNXM172bVhH3YEP5ogbXlnHX00FA11fkLl46RzfltvNcOO 5F3kWv5NnIvfG5wjHpftBCFp6Ox6dmJgkmUOJ6l8IoYrHTcrNUxMWBqi+cP/4gRc yVUBxqOg5C54JTd6R5yhTFSLRa3fmpeR7Q+WyIAKtCTHB701ETk= =Uz0f -----END PGP SIGNATURE----- Merge tag 'mtk-soc-for-v6.15' of https://git.kernel.org/pub/scm/linux/kernel/git/mediatek/linux into soc/drivers MediaTek driver updates for v6.15 This adds entries for new and missing SoCs in the MediaTek SoCInfo driver (MT8370AV/AZA, MT8390AV/AZA) and an extra entry for a new revision of the MT8395AV/ZA SoC.

firmware: arm_scmi: use ioread64() instead of ioread64_hi_lo()
The scmi_common_fastchannel_db_ring() function calls either ioread64()
or ioread64_hi_lo() depending on whether it is compiler for 32-bit
or 64-bit architectures.
The same logic is used to define ioread64() itself in the
linux/io-64-nonatomic-hi-lo.h header file, so the special case
is not really needed.
The behavior here should not change at all.

Arm FF-A updates for v6.15
This update primarily focuses on FF-A framework notification support
along with other improvements, including UUID handling enhancements
and various fixes.
1. FF-A framework notification upport
- Adds support for multiple UUIDs per partition to register individual
SRI callbacks.
- Handles Rx buffer full framework notifications and provides a general
interface for future extensions.
2. Improved multiple UUID/services per-partition handling
- Adds support for UUID passing in FFA_MSG_SEND2, improving multiple
UUID/service support in the driver.
- Introduces a helper function to check whether a partition can
receive REQUEST2 messages.
3. Partition handling generic improvements
- Implements device unregistration for better partition cleanup.
- Improves handling of the host partition presence in partition info.
4. FF-A version updates
- Upgrades the driver version to FF-A v1.2.
- Rejects major versions higher than the driver version as incompatible.
5. Big-Endian support fixes
- Fixes big-endian issues in:
__ffa_partition_info_regs_get()
__ffa_partition_info_get()
- Big-endian support is still incomplete, and only these changes can
be verified without additional application/testing updates at the
moment. We can discover all the partitions correctly with big-endian
kernel now.
6. Miscellaneous fixes
- Fixes function prototype misalignments in: sync_send_receive{,2}
- Adds explicit type casting for return values from: FFA_VERSION
and NOTIFICATION_INFO_GET
- Corrects vCPU list parsing in ffa_notification_info_get().
7. UUID management in the driver and DMA mask updates
- Replaces UUID buffer with the standard UUID format in ffa_partition_info
structure.
- Fixes a typo in some FF-A bus macros.
- Sets dma_mask for FF-A devices.
In short, this update enhances notification handling, UUID support, and
overall robustness of the FF-A driver while addressing multiple fixes
and cleanups.

Arm SCMI updates for v6.15
Couple of updates around the flexibility in SCMI device names and addition of name, protocol id attributes and modalias for SCMI devices in the sysfs. Currently, in the scmi_protocol_device_request() function, SCMI device names ust be unique across all protocols. However, this constraint is being relaxed, allowing devices in different protocols to share the same name. The change aims to provide more flexibility in naming devices across various protocols. Two attributes: name and protocol ID is being added to the SCMI device in the sysfs along with the support for the modalias. These attributes aim to enhance device identification and management. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmfFoCcACgkQAEG6vDF+ 4piYkRAAhUsFR41gMzxKnsf1oIO3kV+6ZU8azQiHRldJEvKo8uP29XhDUYRaQau4 4ubh/4ZFR+ZMzvrVufHWklwC177bjstL075YuNF+q7U0SQ7iF1n8Fmma8JoJd/EC Tz23aW/lTuZKAFu+//YvoNnVUJZx3EB/hddcfvlQxODlwArldwblG+ftrYmGB0Cv lp5smQO1I4HnVyP3ptwIKVol5RpFnpXXflTpsCNovgfptPOGDL+HTILf4RqsWifC TxLfdgi4ciF1K3Yb9jZByBhud30JnjK/xQQTQ3I6+n66Cm29DSPTtHF5wzYalBcs ZfNiSgy8PS60WH13eGaTHYvq26BUmKu2kyi2JpdBM9DneRb16fNuv4amYrKPfbeE bYrU9Uey491zKjBnjUu1JxFvMuNzVolvztax4CAp6SbbkI22XF1OZcxt4ydVDgzQ fykc2gNr/uO/unLWnzsOYRlE/DalYsPpsuK7uNIIXPMe9JCOtOs1JOD6Pj68kNyV Gh+uCJc/eRXPg/eBchBetq9TTV+DFfMP1Rh11up0a8mrmquL/UnORORMurK922px mS6kmewHBDccwC4V4FTbaHmNivaKHhJRRNaBEV+pTkxFits2ehjfsAsxIva144Gc NLxP+Kbux5uMa/UsvXUSY+fktueh8SnmkJkUO3txixayHY3cXxs= =DMuT -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmfJyuoACgkQYKtH/8kJ UidiXQ//Qms9GfMxzJYxiJ8HCQOlvetuQJNs2u3Rhr1pWkCFxHq4sKdYpSRcwN+I MkgR4sfiMzXjqKzWl2MxJuwduZmCyo7RaHi+iyH3l/Xpwlofv+WrJkUSsTutQB+V fMwMNv8yK4Lb1Abm8JH70b0UIyXBpDmYMfkDftbj0jDV+wH+JOMaJwkVtQFA0LI+ XFIDUGV49FvZowZW1AjChdA5xtl63af9EtkEE0e6X/MFmUhg2DaX2Me1+tEchuRB LBKB49TS1v0ACT/O6u5ZBK7Mg1H4bisHMs7PpZHokU1P3FTNJqpZEESG4mE9fOG+ 5WXcvnsdL1jZjl3Mwr5szHBBlOAb8QRuQOld7I9jqSvfNrCl6jR+UQErl4UUTkJa xmwPpjl+5bzgbzVrGXNrTxiL4m/fi9HKxJiuPMny1tA3kIqHXjQPA1eXv6sUWQt0 dquCzvx5lAtHQ/m8XJ2v0ahRkWHeMyUiR1+89Zbl10gdrzDv9BfNRIvsYpiw3xRr 4WEK8XBZuCBaJus3lOt72mnPJxfNGMJk1CWp0V44jHZwBxAPJHARSEpop0azIYFK 5tKUeB/2EB5Ryh13ufdc9uXz60lf6cb2MbcfRm9IPpzQxmZ4csM2aZ5yrt3C/Y81 /NS24mV6aiATl9p1o71u8d9JZbeaWk7ogSExgrPQgChmLIE9eYQ= =cVvD -----END PGP SIGNATURE----- Merge tag 'scmi-updates-6.15' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.15 Couple of updates around the flexibility in SCMI device names and addition of name, protocol id attributes and modalias for SCMI devices in the sysfs.

MediaTek ARM64 DTS updates for v6.15
This adds new SoCs and new machines, other than improving support for
currently supported ones.
In particular, for SoCs:
- Airoha EN7581 gets support for its SCU clock controller, SPI NAND,
hardware RNG, pinctrl, and i2c controllers;
- MediaTek MT8365 SoC gets support for all of its Display Controller
components;
- MediaTek Genio 510 MT8370 - a lower binned variant of Genio 700
MT8390 (which, in turn, is the same as MT8188) - is introduced;
- MT8188 gets support for more Display Controller components (DSC
and MERGE), for the tertiary MSDC (eMMC/SD/SDIO) controller, and
for the MTU3 USB DRD controllers;
- MT8195 and MT8188 both get migrated to the new OF Graph used for
defining a pipeline for the Display Controller components (as
this was previously hardcoded per-board in the drm driver, ugh!);
..and for boards:
- Google Kukui (MT8183) is switched to Elan touchscreen driver
instead of hid-over-i2c to fix probe failures in some cases;
- Google Cherry (MT8195) and Geralt (MT8188) Chromebooks get
migrated to using OF Graph for defining their board specific
part of the display pipeline;
- MediaTek Genio 350 (mt8365) EVK board adds support for HDMI output
through the iTE IT66121 chip, and for DSI output to the Startek
KD070FHFID015 display;
- MediaTek Genio 510 EVK board is introduced with a common devicetree
between mt8390 and mt8370 (Genio 700 and Genio 510) EVKs;
- MediaTek Genio 700 (and 510) EVKs get support for their integrated
dual Digital Microphones, for their RichTek RT1715 USB Type-C
Controller with USB-PD capability, the iTE IT5205 Alternate Mode
Passive MUX (USB3.1/DP1.4), and for USB Gadget/Host switching
through the MTU3 DRD Controller, other than for USB in general;
- MediaTek Genio 1200 EVK gets support for its MediaTek MT6360 PMIC
integrated Type-C Controller, and the IT5205 MUX;
- Radxa NIO-12L gets its DSI display pipeline preconfigured and also
the introduction of a devicetree overlay for the official Radxa
8HD DSI panel, enabling display output over DSI.
And fixes/cleanups:
- MT8173 gets fixes for bindings validation: PMIC node drops the
unnecessary address/size cells, disp-pwm gets its compatibles
list fixed (as mt6595 was not expected there), and some nodes
got the right name (clock controllers were disguides as power
controllers, and intpol was changed to interrupt-controller);
- MT8188-based (MT8390) Genio boards get a fix for duplicated
regulator name;
- MT6359 PMIC gets fixes for audio-codec node validation.

xhci: Handle spurious events on Etron host isoc enpoints
Unplugging a USB3.0 webcam from Etron hosts while streaming results
in errors like this:
[ 2.646387] xhci_hcd 0000:03:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 18 comp_code 13
[ 2.646446] xhci_hcd 0000:03:00.0: Looking for event-dma 000000002fdf8630 trb-start 000000002fdf8640 trb-end 000000002fdf8650
[ 2.646560] xhci_hcd 0000:03:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 18 comp_code 13

Etron xHC generates two transfer events for the TRB if an error is
detected while processing the last TRB of an isoc TD.
The first event can be any sort of error (like USB Transaction or
Babble Detected, etc), and the final event is Success.
The xHCI driver will handle the TD after the first event and remove it
from its internal list, and then print an "Transfer event TRB DMA ptr
not part of current TD" error message after the final event.

usb: xhci: Unify duplicate inc_enq() code

usb: xhci: Apply the link chain quirk on NEC isoc endpoints
Two clearly different specimens of NEC uPD720200 (one with start/stop bug, one without) were seen to cause IOMMU faults after some Missed Service Errors. Faulting address is immediately after a transfer ring segment and patched dynamic debug messages revealed that the MSE was received when waiting for a TD near the end of that segment: [ 1.041954] xhci_hcd: Miss service interval error for slot 1 ep 2 expected TD DMA ffa08fe0 [ 1.042120] xhci_hcd: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0005 address=0xffa09000 flags=0x0000] [ 1.042146] xhci_hcd: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0005 address=0xffa09040 flags=0x0000] It gets even funnier if the next page is a ring segment accessible to the HC. Below, it reports MSE in segment at ff1e8000, plows through a zero-filled page at ff1e9000 and starts reporting events for TRBs in page at ff1ea000 every microframe, instead of jumping to seg ff1e6000.

Lastly, an error from a different USB device on another HC. Was it caused by the above? I don't know, but it may have been. The disk was working without any other issues and generated PCIe traffic to starve the NEC of upstream BW and trigger those MSEs. The two HCs shared one x1 slot by means of a commercial "PCIe splitter" board. [ 7.162604] usb 10-2: reset SuperSpeed USB device number 3 using xhci_hcd [ 7.178990] sd 9:0:0:0: [sdb] tag#0 UNKNOWN(0x2003) Result: hostbyte=0x07 driverbyte=DRIVER_OK cmd_age=0s [ 7.179001] sd 9:0:0:0: [sdb] tag#0 CDB: opcode=0x28 28 00 04 02 ae 00 00 02 00 00 [ 7.179004] I/O error, dev sdb, sector 67284480 op 0x0:(READ) flags 0x80700 phys_seg 5 prio class 0 Fortunately, it appears that this ridiculous bug is avoided by setting the chain bit of Link TRBs on isochronous rings. Other ancient HCs are known which also expect the bit to be set and they ignore Link TRBs if it's not. Reportedly, 0.95 spec guaranteed that the bit is set. The bandwidth-starved NEC HC running a 32KB/uframe UVC endpoint reports tens of MSEs per second and runs into the bug within seconds. Chaining Link TRBs allows the same workload to run for many minutes, many times. No negative side effects seen in UVC recording and UAC playback with a few devices at full speed, high speed and SuperSpeed. The problem doesn't reproduce on the newer Renesas uPD720201/uPD720202 and on old Etron EJ168 and VIA VL805 (but the VL805 has other bug).

xhci: Prevent early endpoint restart when handling STALL errors.
Ensure that an endpoint halted due to device STALL is not restarted before a Clear_Feature(ENDPOINT_HALT) request is sent to the device. The host side of the endpoint may otherwise be started early by the 'Set TR Deq' command completion handler which is called if dequeue is moved past a cancelled or halted TD. Prevent this with a new flag set for bulk and interrupt endpoints when a Stall Error is received. Clear it in hcd->endpoint_reset() which is called after Clear_Feature(ENDPOINT_HALT) is sent. Also add a debug message if a class driver queues a new URB after the STALL. Note that class driver might not be aware of the STALL yet when it submits the URB as URBs are given back in BH.

usb: xhci: move debug capabilities from trb_in_td() to handle_tx_event()
Function trb_in_td() currently includes debug capabilities that are triggered when its debug argument is set to true. The only consumer of these debug capabilities is handle_tx_event(), which calls trb_in_td() twice, once for its primary functionality and a second time solely for debugging purposes if the first call returns 'NULL'. This approach is inefficient and can lead to confusion, as trb_in_td() executes the same code with identical arguments twice, differing only in the debug output during the second execution. To enhance clarity and efficiency, move the debug capabilities out of trb_in_td() and integrates them directly into handle_tx_event(). This change reduces the argument count of trb_in_td() and ensures that debug steps are executed only when necessary, streamlining the function's operation.

Relocate trb_in_td() and marks it as static, as it's exclusively utilized in xhci-ring.c. This adjustment lays the groundwork for future rework of the function.

usb: xhci: set page size to the xHCI-supported size
The current xHCI driver does not validate whether a page size of 4096
bytes is supported. Address the issue by setting the page size to the
value supported by the xHCI controller, as read from the Page Size
register. In the event of an unexpected value; default to a 4K page size.
Additionally, this commit removes unnecessary debug messages and instead
prints the supported and used page size once.
The xHCI controller supports page sizes of (2^{(n+12)}) bytes, where 'n'
is the Page Size Bit. Only one page size is supported, with a maximum
page size of 128 KB.

usb: xhci: correct debug message page size calculation
The ffs() function returns the index of the first set bit, starting from 1.
If no bits are set, it returns zero. This behavior causes an off-by-one
page size in the debug message, as the page size calculation [1]
is zero-based, while ffs() is one-based.
Fix this by subtracting one from the result of ffs(). Note that since
variable 'val' is unsigned, subtracting one from zero will result in the
maximum unsigned integer value. Consequently, the condition 'if (val < 16)'
will still function correctly.
[1], Page size: (2^(n+12)), where 'n' is the set page size bit.

usb: xhci: Skip only one TD on Ring Underrun/Overrun
If skipping is deferred to events other than Missed Service Error itsef, it means we are running on an xHCI 1.0 host and don't know how many TDs were missed until we reach some ordinary transfer completion event. And in case of ring xrun, we can't know where the xrun happened either. If we skip all pending TDs, we may prematurely give back TDs added after the xrun had occurred, risking data loss or buffer UAF by the xHC. If we skip none, a driver may become confused and stop working when all its URBs are missed and appear to be "in flight" forever. Skip exactly one TD on each xrun event - the first one that was missed, as we can now be sure that the HC has finished processing it. Provided that one more TD is queued before any subsequent doorbell ring, it will become safe to skip another TD by the time we get an xrun again.

usb: xhci: Expedite skipping missed isoch TDs on modern HCs
xHCI spec rev. 1.0 allowed the TRB pointer of Missed Service events to be NULL. Having no idea which of the queued TDs were missed and which are waiting, we can only set a flag to skip missed TDs later. But HCs are also allowed to give us pointer to the last missed TRB, and this became mandatory in spec rev. 1.1 and later. Use this pointer, if available, to immediately skip all missed TDs. This reduces latency and risk of skipping-related bugs, because we can now leave the skip flag cleared for future events. Handle Missed Service Error events as 'error mid TD', if applicable, because rev. 1.0 spec excplicitly says so in notes to 4.10.3.2 and later revs in 4.10.3.2 and 4.11.2.5.2. Notes to 4.9.1 seem to apply. Tested on ASM1142 and ASM3142 v1.1 xHCs which provide TRB pointers. Tested on AMD, Etron, Renesas v1.0 xHCs which provide TRB pointers. Tested on NEC v0.96 and VIA v1.0 xHCs which send a NULL pointer. Change inspired by a discussion about realtime USB audio.

usb: xhci: Fix isochronous Ring Underrun/Overrun event handling
The TRB pointer of these events points at enqueue at the time of error occurrence on xHCI 1.1+ HCs or it's NULL on older ones. By the time we are handling the event, a new TD may be queued at this ring position. I can trigger this race by rising interrupt moderation to increase IRQ handling delay. Similar delay may occur naturally due to system load. If this ever happens after a Missed Service Error, missed TDs will be skipped and the new TD processed as if it matched the event. It could be given back prematurely, risking data loss or buffer UAF by the xHC. Don't complete TDs on xrun events and don't warn if queued TDs don't match the event's TRB pointer, which can be NULL or a link/no-op TRB. Don't warn if there are no queued TDs at all. Now that it's safe, also handle xrun events if the skip flag is clear. This ensures completion of any TD stuck in 'error mid TD' state right before the xrun event, which could happen if a driver submits a finite number of URBs to a buggy HC and then an error occurs on the last TD.

Armv8 FVP/Vexpress/Juno updates for v6.15
The main and bulk of the addition this time is the support for the Arm reference Morello System Development Platform (SDP). The Morello architecture is an experimental extension to Armv8.2-A, enhancing the AArch64 execution state with capabilities for fine-grained memory protection and scalable software compartmentalization. However these changes doesn't add any of the support for security enhancements. This is mainly adding device tree support for Morello SDP. The platform iteslf is shipped with ACPI firmware. However, since the ACPI bindings for GPU, DPU, I2C, I2S,..etc are not well defined or not provided in the shipped ACPI firmware, there is a need for the device tree as alternative for the developers focusing on those features. The CPU is called rainier, the architecture is Morello and the platform is Morello SDP board. There is FVP equivalent of the same though they are not completely in feature parity with the real hardware. These changes provide the initial support for Morello SDP and FVP platforms. Apart from this, we have an update to add support for secondary cores on Corstone1000 FVP platform. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmfG0LIACgkQAEG6vDF+ 4phFpg/8D35cH6WWpfWWp0L3EILUVUcWRn0X0a4UJ7z2cl4UMn+cu7h2mzk6rT16 fCVj0Sjuek4AZgVpKT8+3A+GugRAIrmq1teRjfcu34yQFyGh/M95IhAs1ym0RQAN r6Ox0dCjHJc78tQ6zstLElbkINnf9FtrXjmOCeu8nNOkWODupDuLwC/sROavHXSD Yr6+ACCMBvfAIVQUFa1tC1YOvJH/+wKAjISVFJoB7hNG/VqLLEQNQ15HH/Gp97Vn 18oj5471GyIsKXiT2a3hnitDKfnRGnxLVRxSOEFGVR8n0D+HNphYQi11fi1CSkio HI6WDa3m1QP7CGlIW7PD+qClT7djNLUjcQglIF4+SV3NZWotGRRN6Uk7Bq+G24cS jFlXVy3iTfdGwvsnRU6S3WOdHTfjxOeJN6Bei9K262LUkCCl/t7M0q1EKu9twOY+ L0AZvk+g2kqm64KbxHxrHJYTE64ykpw6AnO1vXIM5xR1ov1/XVrzPTPfIIgI4Tb4 r99iIxhThXYe/bJ4yW4JKdW7CG6ZeyCVeIV1/MkhztlnsnR4O5EA8orEntQUdLOY VB/bHwVWCwvpSGmc928cxVUbfHfq/wyEwYBnEmxclAHug8mcSCgPtH52fhB69VWS uZAth1lqztgxS6kKN6TzeYvH2gxTeN5v+DWUgrktNOzIsAFTH4I= =QVaZ -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmfJwy4ACgkQYKtH/8kJ UifGKRAA3Ke0JZLQSnnaSxTMctu+1CqT14m+sZ4ohVmncRPpG6v2mBPIxqxm1ivC X1fS2DJOO6/bASyhG9p05psW3zSyWNlsppiw3Sc5GtpuqBOPGbeTcA6WVT0TnMAy KrAlmeisql+SBKBNGkv0XW58fAbqeYCR/hPthQoqgHpWMON8lBMQvnx+JiH7IzTH /CYt1Fkqm0L1O4vz0lUfdjhdJ79eqvHpkvpdaNZK3mwPe49WVS4hTrgfJeq8B8Pp Z0pqmXTIeVfrc1aSKCPoOLNys8vxhTjazXzfto7hCahlUWNWCoPpUryK7MA6qo5f aOKP8AwsZhJ0tr4xf1u1kYYcjUDI7sYSTi9g/4oLuTjXTCnmXMIZWO5/fOBn574i mx3UK7UD6n/PhNWzgSbJGzWtPzOcaMycvDKLbpuU2UT1YRVUegpoecPApicntt0a IfBTEgWvLkpjgeP0AODqiuM26xWbfxdrd9iH9JIIwsoKnHO86/8QlNBqLB9+fHhZ 9FhAs48Y+C7B4DUOUIXHLD8TYD3zhIjM/sE+BJVGUQvtiFqBgfC9/rZNMMMwxsV5 jVnzSGbFO0RKSQOJr27lcydRICGaeINmEI+wKVJuQFutAtXf9p9jCbHi744Rz0no QSnwB+5p+hZLb9tx+DkIakG/IwscvLbg86/WV3L/IjLV+imHVv4= =Pf5p -----END PGP SIGNATURE----- Merge tag 'juno-updates-6.15' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/dt Armv8 FVP/Vexpress/Juno updates for v6.15 The main and bulk of the addition this time is the support for the Arm reference Morello System Development Platform (SDP).

drm/sched: Update timedout_job()'s documentation
drm_sched_backend_ops.timedout_job()'s documentation is outdated. It mentions the deprecated function drm_sched_resubmit_jobs(). Furthermore, it does not point out the important distinction between hardware and firmware schedulers. Since firmware schedulers typically only use one entity per scheduler, timeout handling is significantly more simple because the entity the faulted job came from can just be killed without affecting innocent processes. Update the documentation with that distinction and other details. Reformat the docstring to work to a unified style with the other handles.

drm/sched: Document run_job() refcount hazard
drm_sched_backend_ops.run_job() returns a dma_fence for the scheduler. That fence is signalled by the driver once the hardware completed the associated job. The scheduler does not increment the reference count on that fence, but implicitly expects to inherit this fence from run_job(). This is relatively subtle and prone to misunderstandings. This implies that, to keep a reference for itself, a driver needs to call dma_fence_get() in addition to dma_fence_init() in that callback. It's further complicated by the fact that the scheduler even decrements the refcount in drm_sched_run_job_work() since it created a new reference in drm_sched_fence_scheduled(). It does, however, still use its pointer to the fence after calling dma_fence_put() - which is safe because of the aforementioned new reference, but actually still violates the refcounting rules. Move the call to dma_fence_put() to the position behind the last usage of the fence.

ARM: OMAP1: select CONFIG_GENERIC_IRQ_CHIP
When GENERIC_IRQ_CHIP is disabled, OMAP1 kernels fail to link:
arm-linux-gnueabi-ld: arch/arm/mach-omap1/irq.o: in function `omap1_init_irq':
irq.c:(.init.text+0x1e8): undefined reference to `irq_alloc_generic_chip'
arm-linux-gnueabi-ld: irq.c:(.init.text+0x228): undefined reference to `irq_setup_generic_chip'
arm-linux-gnueabi-ld: irq.c:(.init.text+0x2a8): undefined reference to `irq_gc_set_wake'
arm-linux-gnueabi-ld: irq.c:(.init.text+0x2b0): undefined reference to `irq_gc_mask_set_bit'
arm-linux-gnueabi-ld: irq.c:(.init.text+0x2b4): undefined reference to `irq_gc_mask_clr_bit'
This has apparently been the case for many years, but I never caught it
in randconfig builds until now, as there are dozens of other drivers
that also 'select GENERIC_IRQ_CHIP' and statistically there is almost
always one of them enabled.
Fixes:

drm/sched: Adjust outdated docu for run_job()
The documentation for drm_sched_backend_ops.run_job() mentions a certain function called drm_sched_job_recovery(). This function does not exist. What's actually meant is drm_sched_resubmit_jobs(), which is by now also deprecated. Furthermore, the scheduler expects to "inherit" a reference on the fence from the run_job() callback. This, so far, is also not documented. Remove the mention of the removed function. Discourage the behavior of drm_sched_backend_ops.run_job() being called multiple times for the same job. Document the necessity of incrementing the refcount in run_job().
