Nouveau deallocates a few buffers post GPU init which are required for GPU suspend/resume to function correctly. This is likely not as big an issue on systems where the NVGPU is the only GPU, but on multi-GPU set ups it leads to a regression where the kernel module errors and results in a system-wide rendering freeze. This commit addresses that regression by moving the two buffers required for suspend and resume to be deallocated at driver unload instead of post init.

Chip outputs are enabled[1] before actual reset is performed[2] which might cause pin output value to flip flop if previous pin value was set to 1. Fix that behavior by making sure chip is fully reset before all outputs are enabled. Flip-flop can be noticed when module is removed and inserted again and one of the pins was changed to 1 before removal. 100 microsecond flipping is noticeable on oscilloscope (100khz SPI bus). For a properly reset chip - output is enabled around 100 microseconds (on 100khz SPI bus) later during probing process hence should be irrelevant behavioral change.

Hyper-V hosts can omit the _SYNC flag to due a bug on resume from modern suspend. In such a case, the guest may fail to update its time-of-day to account for the period when it was suspended, and could proceed with a significantly wrong time-of-day. In such a case when the guest is significantly behind, fix it by treating a _SAMPLE the same as if _SYNC was received so that the guest time-of-day is updated.

… of memory The VMBUS_RING_SIZE macro adds space for a ring buffer header to the requested ring buffer size. The header size is always 1 page, and so its size varies based on the PAGE_SIZE for which the kernel is built. If the requested ring buffer size is a large power-of-2 size and the header size is small, the resulting size is inefficient in its use of memory. For example, a 512 Kbyte ring buffer with a 4 Kbyte page size results in a 516 Kbyte allocation, which is rounded to up 1 Mbyte by the memory allocator, and wastes 508 Kbytes of memory. In such situations, the exact size of the ring buffer isn't that important, and it's OK to allocate the 4 Kbyte header at the beginning of the 512 Kbytes, leaving the ring buffer itself with just 508 Kbytes. The memory allocation can be 512 Kbytes instead of 1 Mbyte and nothing is wasted. Update VMBUS_RING_SIZE to implement this approach for "large" ring buffer sizes. "Large" is somewhat arbitrarily defined as 8 times the size of the ring buffer header (which is of size PAGE_SIZE). For example, for 4 Kbyte PAGE_SIZE, ring buffers of 32 Kbytes and larger use the first 4 Kbytes as the ring buffer header. For 64 Kbyte PAGE_SIZE, ring buffers of 512 Kbytes and larger use the first 64 Kbytes as the ring buffer header. In both cases, smaller sizes add space for the header so the ring size isn't reduced too much by using part of the space for the header. For example, with a 64 Kbyte page size, we don't want a 128 Kbyte ring buffer to be reduced to 64 Kbytes by allocating half of the space for the header. In such a case, the memory allocation is less efficient, but it's the best that can be done. While the new algorithm slightly changes the amount of space allocated for ring buffers by drivers that use VMBUS_RING_SIZE, the devices aren't known to be sensitive to small changes in ring buffer size, so there shouldn't be any effect.

A recent commit removing the use of screen_info introduced a logic error. The error causes hvfb_getmem() to always return -ENOMEM for Generation 2 VMs. As a result, the Hyper-V frame buffer device fails to initialize. The error was introduced by removing an "else if" clause, leaving Gen2 VMs to always take the -ENOMEM error path. Fix the problem by removing the error path "else" clause. Gen 2 VMs now always proceed through the MMIO memory allocation code, but with "base" and "size" defaulting to 0.

…dl_header() create_gpadl_header() creates a message header, and one or more message bodies if the number of GPADL entries exceeds what fits in the header.

Eliminate the duplication by making minor tweaks to the logic and associated comments. While here, simplify the handling of memory allocation errors, and use umin() instead of open coding it.

…lback In preparation for temporarily marking pages not present during a transition between encrypted and decrypted, use slow_virt_to_phys() in the hypervisor callback. As long as the PFN is correct, slow_virt_to_phys() works even if the leaf PTE is not present. The existing functions that depend on vmalloc_to_page() all require that the leaf PTE be marked present, so they don't work.

…zeropad() In a CoCo VM, when transitioning memory from encrypted to decrypted, or vice versa, the caller of set_memory_encrypted() or set_memory_decrypted() is responsible for ensuring the memory isn't in use and isn't referenced while the transition is in progress. The transition has multiple steps, and the memory is in an inconsistent state until all steps are complete. A reference while the state is inconsistent could result in an exception that can't be cleanly fixed up. However, the kernel load_unaligned_zeropad() mechanism could cause a stray reference that can't be prevented by the caller of set_memory_encrypted() or set_memory_decrypted(), so there's specific code to handle this case. But a CoCo VM running on Hyper-V may be configured to run with a paravisor, with the #VC or #VE exception routed to the paravisor. There's no architectural way to forward the exceptions back to the guest kernel, and in such a case, the load_unaligned_zeropad() specific code doesn't work. To avoid this problem, mark pages as "not present" while a transition is in progress. If load_unaligned_zeropad() causes a stray reference, a normal page fault is generated instead of #VC or #VE, and the page-fault-based fixup handlers for load_unaligned_zeropad() resolve the reference. When the encrypted/decrypted transition is complete, mark the pages as "present" again.

The current method for signaling the compatibility of a Hyper-V host with MSIs featuring 15-bit APIC IDs relies on a synthetic cpuid leaf. However, for higher VTLs, this leaf is not reported, due to the absence of an IO-APIC. As an alternative, assume that when running at a high VTL, the host supports 15-bit APIC IDs. This assumption is safe, as Hyper-V does not employ any architectural MSIs at higher VTLs This unblocks startup of VTL2 environments with more than 256 CPUs.

Current driver has some asymmetry in the runtime PM calls. On lan78xx_open() it will call usb_autopm_get() and unconditionally usb_autopm_put(). And on lan78xx_stop() it will call only usb_autopm_put(). So far, it was working only because this driver do not activate autosuspend by default, so it was visible only by warning "Runtime PM usage count underflow!". Since, with current driver, we can't use runtime PM with active link, execute lan78xx_open()->usb_autopm_put() only in error case. Otherwise, keep ref counting high as long as interface is open.

…nto HEAD KVM x86 fixes for 6.8, round 2: - When emulating an atomic access, mark the gfn as dirty in the memslot to fix a bug where KVM could fail to mark the slot as dirty during live migration, ultimately resulting in guest data corruption due to a dirty page not being re-copied from the source to the target. - Check for mmu_notifier invalidation events before faulting in the pfn, and before acquiring mmu_lock, to avoid unnecessary work and lock contention. Contending mmu_lock is especially problematic on preemptible kernels, as KVM may yield mmu_lock in response to the contention, which severely degrades overall performance due to vCPUs making it difficult for the task that triggered invalidation to make forward progress. Note, due to another kernel bug, this fix isn't limited to preemtible kernels, as any kernel built with CONFIG_PREEMPT_DYNAMIC=y will yield contended rwlocks and spinlocks. https://lore.kernel.org/all/[email protected]
…86/linux into HEAD KVM GUEST_MEMFD fixes for 6.8: - Make KVM_MEM_GUEST_MEMFD mutually exclusive with KVM_MEM_READONLY to avoid creating ABI that KVM can't sanely support. - Update documentation for KVM_SW_PROTECTED_VM to make it abundantly clear that such VMs are purely a development and testing vehicle, and come with zero guarantees. - Limit KVM_SW_PROTECTED_VM guests to the TDP MMU, as the long term plan is to support confidential VMs with deterministic private memory (SNP and TDX) only in the TDP MMU. - Fix a bug in a GUEST_MEMFD negative test that resulted in false passes when verifying that KVM_MEM_GUEST_MEMFD memslots can't be dirty logged.
The DebugSwap feature of SEV-ES provides a way for confidential guests to use data breakpoints. However, because the status of the DebugSwap feature is recorded in the VMSA, enabling it by default invalidates the attestation signatures. In 6.10 we will introduce a new API to create SEV VMs that will allow enabling DebugSwap based on what the user tells KVM to do. Contextually, we will change the legacy KVM_SEV_ES_INIT API to never enable DebugSwap. For compatibility with kernels that pre-date the introduction of DebugSwap, as well as with those where KVM_SEV_ES_INIT will never enable it, do not enable the feature by default. If anybody wants to use it, for now they can enable the sev_es_debug_swap_enabled module parameter, but this will result in a warning.

…linux/kernel/git/ieee1394/linux1394 Pull firewire fix from Takashi Sakamoto: "A fix to suppress a warning about unreleased IRQ for 1394 OHCI hardware when disabling MSI. In Linux kernel v6.5, a PCI driver for 1394 OHCI hardware was optimized into the managed device resources. Edmund Raile points out that the change brings the warning about unreleased IRQ at the call of pci_disable_msi(), since the API expects that the relevant IRQ has already been released in advance. As long as the API is called in .remove callback of PCI device operation, it is prohibited to maintain the IRQ as the part of managed device resource. As a workaround, the IRQ is explicitly released at .remove callback, before the call of pci_disable_msi(). pci_disable_msi() is legacy API nowadays in PCI MSI implementation. I have a plan to replace it with the modern API in the development for the future version of Linux kernel. So at present I keep them as is" * tag 'firewire-fixes-6.8-final' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394: firewire: ohci: prevent leak of left-over IRQ on unbind

A task can wait on a ring buffer for when it fills up to a specific watermark. The writer will check the minimum watermark that waiters are waiting for and if the ring buffer is past that, it will wake up all the waiters. The waiters are in a wait loop, and will first check if a signal is pending and then check if the ring buffer is at the desired level where it should break out of the loop. If a file that uses a ring buffer closes, and there's threads waiting on the ring buffer, it needs to wake up those threads. To do this, a "wait_index" was used. Before entering the wait loop, the waiter will read the wait_index. On wakeup, it will check if the wait_index is different than when it entered the loop, and will exit the loop if it is. The waker will only need to update the wait_index before waking up the waiters. This had a couple of bugs. One trivial one and one broken by design. The trivial bug was that the waiter checked the wait_index after the schedule() call. It had to be checked between the prepare_to_wait() and the schedule() which it was not. The main bug is that the first check to set the default wait_index will always be outside the prepare_to_wait() and the schedule(). That's because the ring_buffer_wait() doesn't have enough context to know if it should break out of the loop. The loop itself is not needed, because all the callers to the ring_buffer_wait() also has their own loop, as the callers have a better sense of what the context is to decide whether to break out of the loop or not. Just have the ring_buffer_wait() block once, and if it gets woken up, exit the function and let the callers decide what to do next.

"KVM GUEST_MEMFD fixes for 6.8:
- Make KVM_MEM_GUEST_MEMFD mutually exclusive with KVM_MEM_READONLY
to avoid creating an inconsistent ABI (KVM_MEM_GUEST_MEMFD is not
writable from userspace, so there would be no way to write to a
read-only guest_memfd).
- Update documentation for KVM_SW_PROTECTED_VM to make it abundantly
clear that such VMs are purely for development and testing.
- Limit KVM_SW_PROTECTED_VM guests to the TDP MMU, as the long term
plan is to support confidential VMs with deterministic private
memory (SNP and TDX) only in the TDP MMU.
- Fix a bug in a GUEST_MEMFD dirty logging test that caused false
passes.
x86 fixes:
- Fix missing marking of a guest page as dirty when emulating an
atomic access.
- Check for mmu_notifier invalidation events before faulting in the
pfn, and before acquiring mmu_lock, to avoid unnecessary work and
lock contention with preemptible kernels (including
CONFIG_PREEMPT_DYNAMIC in non-preemptible mode).
- Disable AMD DebugSwap by default, it breaks VMSA signing and will
be re-enabled with a better VM creation API in 6.10.

The "shortest_full" variable is used to keep track of the waiter that is waiting for the smallest amount on the ring buffer before being woken up. When a tasks waits on the ring buffer, it passes in a "full" value that is a percentage. 0 means wake up on any data. 1-100 means wake up from 1% to 100% full buffer. As all waiters are on the same wait queue, the wake up happens for the waiter with the smallest percentage. The problem is that the smallest_full on the cpu_buffer that stores the smallest amount doesn't get reset when all the waiters are woken up. It does get reset when the ring buffer is reset (echo > /sys/kernel/tracing/trace). This means that tasks may be woken up more often then when they want to be. Instead, have the shortest_full field get reset just before waking up all the tasks. If the tasks wait again, they will update the shortest_full before sleeping. Also add locking around setting of shortest_full in the poll logic, and change "work" to "rbwork" to match the variable name for rb_irq_work structures that are used in other places.

The .release() function does not get called until all readers of a file descriptor are finished. If a thread is blocked on reading a file descriptor in ring_buffer_wait(), and another thread closes the file descriptor, it will not wake up the other thread as ring_buffer_wake_waiters() is called by .release(), and that will not get called until the .read() is finished. The issue originally showed up in trace-cmd, but the readers are actually other processes with their own file descriptors. So calling close() would wake up the other tasks because they are blocked on another descriptor then the one that was closed(). But there's other wake ups that solve that issue. When a thread is blocked on a read, it can still hang even when another thread closed its descriptor. This is what the .flush() callback is for. Have the .flush() wake up the readers.

…m/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Do not allow large strings (> 4096) as single write to trace_marker The size of a string written into trace_marker was determined by the size of the sub-buffer in the ring buffer. That size is dependent on the PAGE_SIZE of the architecture as it can be mapped into user space. But on PowerPC, where PAGE_SIZE is 64K, that made the limit of the string of writing into trace_marker 64K. One of the selftests looks at the size of the ring buffer sub-buffers and writes that plus more into the trace_marker. The write will take what it can and report back what it consumed so that the user space application (like echo) will write the rest of the string. The string is stored in the ring buffer and can be read via the "trace" or "trace_pipe" files. The reading of the ring buffer uses vsnprintf(), which uses a precision "%.*s" to make sure it only reads what is stored in the buffer, as a bug could cause the string to be non terminated. With the combination of the precision change and the PAGE_SIZE of 64K allowing huge strings to be added into the ring buffer, plus the test that would actually stress that limit, a bug was reported that the precision used was too big for "%.*s" as the string was close to 64K in size and the max precision of vsnprintf is 32K. Linus suggested not to have that precision as it could hide a bug if the string was again stored without a nul byte. Another issue that was brought up is that the trace_seq buffer is also based on PAGE_SIZE even though it is not tied to the architecture limit like the ring buffer sub-buffer is. Having it be 64K * 2 is simply just too big and wasting memory on systems with 64K page sizes. It is now hardcoded to 8K which is what all other architectures with 4K PAGE_SIZE has. Finally, the write to trace_marker is now limited to 4K as there is no reason to write larger strings into trace_marker. - ring_buffer_wait() should not loop. The ring_buffer_wait() does not have the full context (yet) on if it should loop or not. Just exit the loop as soon as its woken up and let the callers decide to loop or not (they already do, so it's a bit redundant). - Fix shortest_full field to be the smallest amount in the ring buffer that a waiter is waiting for. The "shortest_full" field is updated when a new waiter comes in and wants to wait for a smaller amount of data in the ring buffer than other waiters. But after all waiters are woken up, it's not reset, so if another waiter comes in wanting to wait for more data, it will be woken up when the ring buffer has a smaller amount from what the previous waiters were waiting for. - The wake up all waiters on close is incorrectly called frome .release() and not from .flush() so it will never wake up any waiters as the .release() will not get called until all .read() calls are finished. And the wakeup is for the waiters in those .read() calls. * tag 'trace-ring-buffer-v6.8-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Use .flush() call to wake up readers ring-buffer: Fix resetting of shortest_full ring-buffer: Fix waking up ring buffer readers tracing: Limit trace_marker writes to just 4K tracing: Limit trace_seq size to just 8K and not depend on architecture PAGE_SIZE tracing: Remove precision vsnprintf() check from print event
