Some inconsistent usage of white space in the PM-runtime core code causes that code to be somewhat harder to read that it would have been otherwise, so adjust the white space in there to be more consistent with the rest of the code.

A previous change amended try_to_freeze_tasks() with the "what" variable pointing to a string describing the group of tasks subject to the freezing which may be used in the error message in there too, so make that happen.

Using pr_cont() in the tasks freezing code related to system-wide suspend and hibernation is problematic, because the continuation messages printed there are susceptible to interspersing with other unrelated messages which results in output that is hard to understand. Address this issue by modifying try_to_freeze_tasks() to print messages that don't require continuations and adjusting its callers accordingly.

Because rpm_callback() is a wrapper around __rpm_callback(), and the only caller of it after the change eliminating an invocation of it from rpm_idle(), move the former next to the latter to make the code a bit easier to follow.

Rafael J. Wysocki authored
Calling __rpm_callback() from rpm_idle() after adding device links support to the former is a clear mistake. Not only it causes rpm_idle() to carry out unnecessary actions, but it is also against the assumption regarding the stability of PM-runtime status across __rpm_callback() invocations, because rpm_suspend() and rpm_resume() may run in parallel with __rpm_callback() when it is called by rpm_idle() and the device's PM-runtime status can be updated by any of them.

This reverts commit f35b5d7d. It has been reported to cause huge performance regressions on some loads (will-it-scale.per_process_ops, but also building the kernel with clang). The commit did speed up gcc builds by a small amount, so it's not an unambiguous regression, but until the big regressions are understood, let's revert it.

Currently tpm transactions are executed unconditionally in tpm_pm_suspend() function, which may lead to races with other tpm accessors in the system. Specifically, the hw_random tpm driver makes use of tpm_get_random(), and this function is called in a loop from a kthread, which means it's not frozen alongside userspace, and so can race with the work done during system suspend: tpm tpm0: tpm_transmit: tpm_recv: error -52 tpm tpm0: invalid TPM_STS.x 0xff, dumping stack for forensics CPU: 0 PID: 1 Comm: init Not tainted 6.1.0-rc5+ #135 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.0-20220807_005459-localhost 04/01/2014 Call Trace: tpm_tis_status.cold+0x19/0x20 tpm_transmit+0x13b/0x390 tpm_transmit_cmd+0x20/0x80 tpm1_pm_suspend+0xa6/0x110 tpm_pm_suspend+0x53/0x80 __pnp_bus_suspend+0x35/0xe0 __device_suspend+0x10f/0x350 Fix this by calling tpm_try_get_ops(), which itself is a wrapper around tpm_chip_start(), but takes the appropriate mutex.

The "force" argument to write_spec_ctrl_current() is currently ambiguous as it does not guarantee the MSR write. This is due to the optimization that writes to the MSR happen only when the new value differs from the cached value. This is fine in most cases, but breaks for S3 resume when the cached MSR value gets out of sync with the hardware MSR value due to S3 resetting it. When x86_spec_ctrl_current is same as x86_spec_ctrl_base, the MSR write is skipped. Which results in SPEC_CTRL mitigations not getting restored. Move the MSR write from write_spec_ctrl_current() to a new function that unconditionally writes to the MSR. Update the callers accordingly and rename functions.

The V4L2_MEMORY_USERPTR interface is long deprecated and shouldn't be used (and is discouraged for any modern v4l drivers). And Seth Jenkins points out that the fallback to VM_PFNMAP/VM_IO is fundamentally racy and dangerous. Note that it's not even a case that should trigger, since any normal user pointer logic ends up just using the pin_user_pages_fast() call that does the proper page reference counting. That's not the problem case, only if you try to use special device mappings do you have any issues. Normally I'd just remove this during the merge window, but since Seth pointed out the problem cases, we really want to know as soon as possible if there are actually any users of this odd special case of a legacy interface. Neither Hans nor Mauro seem to think that such mis-uses of the old legacy interface should exist. As Mauro says: "See, V4L2 has actually 4 streaming APIs: - Kernel-allocated mmap (usually referred simply as just mmap); - USERPTR mmap; - read(); - dmabuf; The USERPTR is one of the oldest way to use it, coming from V4L version 1 times, and by far the least used one" And Hans chimed in on the USERPTR interface: "To be honest, I wouldn't mind if it goes away completely, but that's a bit of a pipe dream right now" but while removing this legacy interface entirely may be a pipe dream we can at least try to remove the unlikely (and actively broken) case of using special device mappings for USERPTR accesses. This replaces it with a WARN_ONCE() that we can remove once we've hopefully confirmed that no actual users exist. NOTE! Longer term, this means that a 'struct frame_vector' only ever contains proper page pointers, and all the games we have with converting them to pages can go away (grep for 'frame_vector_to_pages()' and the uses of 'vec->is_pfns'). But this is just the first step, to verify that this code really is all dead, and do so as quickly as possible.

for_each_pci_dev() is implemented by pci_get_device(). The comment of pci_get_device() says that it will increase the reference count for the returned pci_dev and also decrease the reference count for the input pci_dev @from if it is not NULL. If we break for_each_pci_dev() loop with pdev not NULL, we need to call pci_dev_put() to decrease the reference count. Add the missing pci_dev_put() for the error path to avoid reference count leak.

As comment of pci_get_domain_bus_and_slot() says, it returns a pci device with refcount increment, when finish using it, the caller must decrease the reference count by calling pci_dev_put(). So call pci_dev_put() after using the 'pdev' to avoid refcount leak. Besides, if the 'pdev' is null or intel_svm_prq_report() returns error, there is no need to trace this fault.

QAT devices on Intel Sapphire Rapids and Emerald Rapids have a defect in address translation service (ATS). These devices may inadvertently issue ATS invalidation completion before posted writes initiated with translated address that utilized translations matching the invalidation address range, violating the invalidation completion ordering. This patch adds an extra device TLB invalidation for the affected devices, it is needed to ensure no more posted writes with translated address following the invalidation completion. Therefore, the ordering is preserved and data-corruption is prevented. Device TLBs are invalidated under the following six conditions: 1. Device driver does DMA API unmap IOVA 2. Device driver unbind a PASID from a process, sva_unbind_device() 3. PASID is torn down, after PASID cache is flushed. e.g. process exit_mmap() due to crash 4. Under SVA usage, called by mmu_notifier.invalidate_range() where VM has to free pages that were unmapped 5. userspace driver unmaps a DMA buffer 6. Cache invalidation in vSVA usage (upcoming) For #1 and #2, device drivers are responsible for stopping DMA traffic before unmap/unbind. For #3, iommu driver gets mmu_notifier to invalidate TLB the same way as normal user unmap which will do an extra invalidation. The dTLB invalidation after PASID cache flush does not need an extra invalidation. Therefore, we only need to deal with #4 and #5 in this patch. #1 is also covered by this patch due to common code path with #5.
