The runtime PM status can only be updated while runtime PM is disabled. Drop the bogus pm_runtime_set_active() call that was made after enabling runtime PM and which (incidentally but correctly) left the runtime PM status set to 'suspended'.

A recent commit moved enabling of runtime PM to GPU load time (first open()) but failed to update the error paths so that runtime PM is disabled if initialisation of the GPU fails. This would trigger a warning about the unbalanced disable count on the next open() attempt. Note that pm_runtime_put_noidle() is sufficient to balance the usage count when pm_runtime_put_sync() fails (and is chosen over pm_runtime_resume_and_get() for consistency reasons).

Some older GPUs (namely a2xx with no opp tables at all and a320 with downstream-remnants gpu pwrlevels) used not to have OPP tables. They both however had just one frequency defined, making it extremely easy to construct such an OPP table from within the driver if need be. Do so and switch all clk_set_rate calls on core_clk to their OPP counterparts.

As per the recommended recovery sequence of adreno gpu, cx gdsc should collapse at hardware before it is turned back ON. This helps to clear out the stale states in hardware before it is reinitialized. Use the genpd notifier along with the newly introduced dev_pm_genpd_synced_poweroff() api to ensure that cx gdsc has collapsed before we turn it back ON.

When a device has multiple power domains, dev->power_domain is left empty during probe. That didn't cause any issue so far because we are freeloading on smmu driver's vote on cx gdsc.

-
Mario Limonciello authored
AMD has issued an advisory indicating that having fTPM enabled in BIOS can cause "stuttering" in the OS. This issue has been fixed in newer versions of the fTPM firmware, but it's up to system designers to decide whether to distribute it. This issue has existed for a while, but is more prevalent starting with kernel 6.1 because commit b006c439 ("hwrng: core - start hwrng kthread also for untrusted sources") started to use the fTPM for hwrng by default. However, all uses of /dev/hwrng result in unacceptable stuttering. So, simply disable registration of the defective hwrng when detecting these faulty fTPM versions. As this is caused by faulty firmware, it is plausible that such a problem could also be reproduced by other TPM interactions, but this hasn't been shown by any user's testing or reports. It is hypothesized to be triggered more frequently by the use of the RNG because userspace software will fetch random numbers regularly. Intentionally continue to register other TPM functionality so that users that rely upon PCR measurements or any storage of data will still have access to it. If it's found later that another TPM functionality is exacerbating this problem a module parameter it can be turned off entirely and a module parameter can be introduced to allow users who rely upon fTPM functionality to turn it on even though this problem is present.

tpm_read_log_acpi() should return -ENODEV when no eventlog from the ACPI table is found. If the firmware vendor includes an invalid log address we are unable to map from the ACPI memory and tpm_read_log() returns -EIO which would abort discovery of the eventlog. Change the return value from -EIO to -ENODEV when acpi_os_map_iomem() fails to map the event log. The following hardware was used to test this issue: Framework Laptop (Pre-production) BIOS: INSYDE Corp, Revision: 3.2 TPM Device: NTC, Firmware Revision: 7.2 Dump of the faulty ACPI TPM2 table: [000h 0000 4] Signature : "TPM2" [Trusted Platform Module hardware interface Table] [004h 0004 4] Table Length : 0000004C [008h 0008 1] Revision : 04 [009h 0009 1] Checksum : 2B [00Ah 0010 6] Oem ID : "INSYDE" [010h 0016 8] Oem Table ID : "TGL-ULT" [018h 0024 4] Oem Revision : 00000002 [01Ch 0028 4] Asl Compiler ID : "ACPI" [020h 0032 4] Asl Compiler Revision : 00040000 [024h 0036 2] Platform Class : 0000 [026h 0038 2] Reserved : 0000 [028h 0040 8] Control Address : 0000000000000000 [030h 0048 4] Start Method : 06 [Memory Mapped I/O] [034h 0052 12] Method Parameters : 00 00 00 00 00 00 00 00 00 00 00 00 [040h 0064 4] Minimum Log Length : 00010000 [044h 0068 8] Log Address : 000000004053D000 Fixes: 0cf577a0 ("tpm: Fix handling of missing event log") Tested-by: Erkki Eilonen <erkki@bearmetal.eu> Signed-off-by: Morten Linderud <morten@linderud.pw> Reviewed-by: Jarkko Sakkinen <jarkko@kernel.org> Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org>

Pull staging driver fixes and removal from Greg KH: "Here are four small staging driver fixes, and one big staging driver deletion for 6.3-rc2. The fixes are: - rtl8192e driver fixes for where the driver was attempting to execute various programs directly from the disk for unknown reasons - rtl8723bs driver fixes for issues found by Hans in testing The deleted driver is the removal of the r8188eu wireless driver as now in 6.3-rc1 we have a "real" wifi driver for one that includes support for many many more devices than this old driver did. So it's time to remove it as it is no longer needed. The maintainers of this driver all have acked its removal. Many thanks to them over the years for working to clean it up and keep it working while the real driver was being developed. All of these have been in linux-next this week with no reported problems" * tag 'staging-6.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: staging: r8188eu: delete driver staging: rtl8723bs: Pass correct parameters to cfg80211_get_bss() staging: rtl8723bs: Fix key-store index handling staging: rtl8192e: Remove call_usermodehelper starting RadioPower.sh staging: rtl8192e: Remove function ..dm_check_ac_dc_power calling a script

Pull clone3 fix from Christian Brauner: "A simple fix for the clone3() system call. The CLONE_NEWTIME allows the creation of time namespaces. The flag reuses a bit from the CSIGNAL bits that are used in the legacy clone() system call to set the signal that gets sent to the parent after the child exits. The clone3() system call doesn't rely on CSIGNAL anymore as it uses a dedicated .exit_signal field in struct clone_args. So we blocked all CSIGNAL bits in clone3_args_valid(). When CLONE_NEWTIME was introduced and reused a CSIGNAL bit we forgot to adapt clone3_args_valid() causing CLONE_NEWTIME with clone3() to be rejected. Fix this" * tag 'kernel.fork.v6.3-rc2' of gitolite.kernel.org:pub/scm/linux/kernel/git/brauner/linux: selftests/clone3: test clone3 with CLONE_NEWTIME fork: allow CLONE_NEWTIME in clone3 flags
