2023-03-20drm/msm/adreno: Use OPP for every GPU generationKonrad Dybcio
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.

2023-03-20drm/msm/a6xx: Use genpd notifier to ensure cx-gdsc collapseAkhil P Oommen
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.

2023-03-12tpm: disable hwrng for fTPM on some AMD designsMario Limonciello
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 b006c439d58db ("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.

2023-03-12tpm/eventlog: Don't abort tpm_read_log on faulty ACPI addressMorten Linderud
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.

2023-03-12cpumask: relax sanity checking constraintsLinus Torvalds
The cpumask_check() was unnecessarily tight, and causes problems for the users of cpumask_next(). We have a number of users that take the previous return value of one of the bit scanning functions and subtract one to keep it in "range". But since the scanning functions end up returning up to 'small_cpumask_bits' instead of the tighter 'nr_cpumask_bits', the range really needs to be using that widened form. [ This "previous-1" behavior is also the reason we have all those comments about /* -1 is a legal arg here. */ and separate checks for that being ok. So we could have just made "small_cpumask_bits-1" be a similar special "don't check this" value. Tetsuo Handa even suggested a patch that only does that for cpumask_next(), since that seems to be the only actual case that triggers, but that all makes it even _more_ magical and special. So just relax the check ] One example of this kind of pattern being the 'c_start()' function in arch/x86/kernel/cpu/proc.c, but also duplicated in various forms on other architectures.
