2 years agodrm/amd/display: Prevent OTG shutdown during PSR SU
Leo Li [Mon, 26 Sep 2022 21:53:55 +0000 (17:53 -0400)]
drm/amd/display: Prevent OTG shutdown during PSR SU

[Why]

Enabling Z10 optimizations allows DMUB to disable the OTG during PSR
link-off. This theoretically saves power by putting more of the display
hardware to sleep. However, we observe that with PSR SU, it causes
visual artifacts, higher power usage, and potential system hang.

This is partly due to an odd behavior with the VStartup interrupt used
to signal DRM vblank events. If the OTG is toggled on/off during a PSR
link on/off cycle, the vstartup interrupt fires twice in quick
succession. This generates incorrectly timed vblank events.
Additionally, it can cause cursor updates to generate visual artifacts.

Note that this is not observed with PSR1 since PSR is fully disabled
when there are vblank event requestors. Cursor updates are also
artifact-free, likely because there are no selectively-updated (SU)
frames that can generate artifacts.

[How]

A potential solution is to disable z10 idle optimizations only when fast
updates (flips & cursor updates) are committed. A mechanism to do so
would require some thoughtful design. Let's just disable idle
optimizations for PSR2 for now.

Dan Williams [Fri, 23 Sep 2022 22:05:56 +0000 (15:05 -0700)]
devdax: Fix soft-reservation memory description

The "hmem" platform-devices that are created to represent the
platform-advertised "Soft Reserved" memory ranges end up inserting a
resource that causes the iomem_resource tree to look like this:

340000000-43fffffff : hmem.0
  340000000-43fffffff : Soft Reserved
    340000000-43fffffff : dax0.0

This is because insert_resource() reparents ranges when they completely
intersect an existing range.

This matters because code that uses region_intersects() to scan for a
given IORES_DESC will only check that top-level 'hmem.0' resource and
not the 'Soft Reserved' descendant.

So, to support EINJ (via einj_error_inject()) to inject errors into
memory hosted by a dax-device, be sure to describe the memory as
IORES_DESC_SOFT_RESERVED. This is a follow-on to:

commit b13a3e5fd40b ("ACPI: APEI: Fix _EINJ vs EFI_MEMORY_SP")

...that fixed EINJ support for "Soft Reserved" ranges in the first
instance.

io_uring: ensure that cached task references are always put on exit

io_uring caches task references to avoid doing atomics for each of them
per request. If a request is put from the same task that allocated it,
then we can maintain a per-ctx cache of them. This obviously relies
on io_uring always pruning caches in a reliable way, and there's
currently a case off io_uring fd release where we can miss that.

One example is a ring setup with IOPOLL, which relies on the task
polling for completions, which will free them. However, if such a task
submits a request and then exits or closes the ring without reaping
the completion, then ring release will reap and put. If release happens
from that very same task, the completed request task refs will get
put back into the cache pool. This is problematic, as we're now beyond
the point of pruning caches.

Manually drop these caches after doing an IOPOLL reap. This releases
references from the current task, which is enough. If another task
happens to be doing the release, then the caching will not be
triggered and there's no issue.

vmlinux.lds.h: CFI: Reduce alignment of jump-table to function alignment

Due to undocumented, hysterical raisins on x86, the CFI jump-table
sections in .text are needlessly aligned to PMD_SIZE in the vmlinux
linker script. When compiling a CFI-enabled arm64 kernel with a 64KiB
page-size, a PMD maps 512MiB of virtual memory and so the .text section
increases to a whopping 940MiB and blows the final Image up to 960MiB.
Others report a link failure.

Since the CFI jump-table requires only instruction alignment, reduce the
alignment directives to function alignment for parity with other parts
of the .text section. This reduces the size of the .text section for the
aforementioned 64KiB page size arm64 kernel to 19MiB for a much more
reasonable total Image size of 39MiB.

Add a comment to kvm_emulate_xsetbv() to call out that the CPU checks
CR4.OSXSAVE before checking for intercepts.  AMD'S APM implies that #UD
has priority (says that intercepts are checked before #GP exceptions),
while Intel's SDM says nothing about interception priority.  However,
testing on hardware shows that both AMD and Intel CPUs prioritize the #UD
over interception.

Dr. David Alan Gilbert [Wed, 24 Aug 2022 03:30:56 +0000 (03:30 +0000)]
KVM: x86: Always enable legacy FP/SSE in allowed user XFEATURES

Allow FP and SSE state to be saved and restored via KVM_{G,SET}_XSAVE on
XSAVE-capable hosts even if their bits are not exposed to the guest via
XCR0.

Failing to allow FP+SSE first showed up as a QEMU live migration failure,
where migrating a VM from a pre-XSAVE host, e.g. Nehalem, to an XSAVE
host failed due to KVM rejecting KVM_SET_XSAVE.  However, the bug also
causes problems even when migrating between XSAVE-capable hosts as
KVM_GET_SAVE won't set any bits in user_xfeatures if XSAVE isn't exposed
to the guest, i.e. KVM will fail to actually migrate FP+SSE.

Because KVM_{G,S}ET_XSAVE are designed to allowing migrating between
hosts with and without XSAVE, KVM_GET_XSAVE on a non-XSAVE (by way of
fpu_copy_guest_fpstate_to_uabi()) always sets the FP+SSE bits in the
header so that KVM_SET_XSAVE will work even if the new host supports
XSAVE.

Sean Christopherson [Wed, 24 Aug 2022 03:30:55 +0000 (03:30 +0000)]
KVM: x86: Reinstate kvm_vcpu_arch.guest_supported_xcr0

Reinstate the per-vCPU guest_supported_xcr0 by partially reverting
commit 988896bb6182; the implicit assessment that guest_supported_xcr0 is
always the same as guest_fpu.fpstate->user_xfeatures was incorrect.

kvm_vcpu_after_set_cpuid() isn't the only place that sets user_xfeatures,
as user_xfeatures is set to fpu_user_cfg.default_features when guest_fpu
is allocated via fpu_alloc_guest_fpstate() => __fpstate_reset().
guest_supported_xcr0 on the other hand is zero-allocated.  If userspace
never invokes KVM_SET_CPUID2, supported XCR0 will be '0', whereas the
allowed user XFEATURES will be non-zero.

Practically speaking, the edge case likely doesn't matter as no sane
userspace will live migrate a VM without ever doing KVM_SET_CPUID2. The
primary motivation is to prepare for KVM intentionally and explicitly
setting bits in user_xfeatures that are not set in guest_supported_xcr0.

Because KVM_{G,S}ET_XSAVE can be used to svae/restore FP+SSE state even
if the host doesn't support XSAVE, KVM needs to set the FP+SSE bits in
user_xfeatures even if they're not allowed in XCR0, e.g. because XCR0

Theodore Ts'o [Thu, 1 Sep 2022 22:03:14 +0000 (18:03 -0400)]
ext4: limit the number of retries after discarding preallocations blocks

This patch avoids threads live-locking for hours when a large number
threads are competing over the last few free extents as they blocks
getting added and removed from preallocation pools.  From our bug
reporter:

   A reliable way for triggering this has multiple writers
   continuously write() to files when the filesystem is full, while
   small amounts of space are freed (e.g. by truncating a large file
   -1MiB at a time). In the local filesystem, this can be done by
   simply not checking the return code of write (0) and/or the error
   (ENOSPACE) that is set. Over NFS with an async mount, even clients
   with proper error checking will behave this way since the linux NFS
   client implementation will not propagate the server errors [the
   write syscalls immediately return success] until the file handle is
   closed. This leads to a situation where NFS clients send a
   continuous stream of WRITE rpcs which result in ERRNOSPACE -- but
   since the client isn't seeing this, the stream of writes continues
   at maximum network speed.

   When some space does appear, multiple writers will all attempt to
   claim it for their current write. For NFS, we may see dozens to
   hundreds of threads that do this.

   The real-world scenario of this is database backup tooling (in
   particular, github.com/mdkent/percona-xtrabackup) which may write
   large files (>1TiB) to NFS for safe keeping. Some temporary files
   are written, rewound, and read back -- all before closing the file
   handle (the temp file is actually unlinked, to trigger automatic
   deletion on close/crash.) An application like this operating on an
   async NFS mount will not see an error code until TiB have been
   written/read.

   The lockup was observed when running this database backup on large
   filesystems (64 TiB in this case) with a high number of block
   groups and no free space. Fragmentation is generally not a factor
   in this filesystem (~thousands of large files, mostly contiguous
   except for the parts written while the filesystem is at capacity.)

When the PWM driver was changed to disable clocks if no PWMs are enabled,
it ended up also disabling the shared parent with the UART, since the

net: sunhme: Fix packet reception for len < RX_COPY_THRESHOLD

There is a separate receive path for small packets (under 256 bytes).
Instead of allocating a new dma-capable skb to be used for the next packet,
this path allocates a skb and copies the data into it (reusing the existing
sbk for the next packet). There are two bytes of junk data at the beginning
of every packet. I believe these are inserted in order to allow aligned DMA
and IP headers. We skip over them using skb_reserve. Before copying over
the data, we must use a barrier to ensure we see the whole packet. The
current code only synchronizes len bytes, starting from the beginning of
the packet, including the junk bytes. However, this leaves off the final
two bytes in the packet. Synchronize the whole packet.

To reproduce this problem, ping a HME with a payload size between 17 and
214

$ ping -s 17 <hme_address>

which will complain rather loudly about the data mismatch. Small packets
(below 60 bytes on the wire) do not have this issue. I suspect this is
related to the padding added to increase the minimum packet size.

... once the kernel leave the SYSTEM_BOOTING state, the fixmap pagetable
entries are protected by the fixmap_lock mutex.

The new KPTI rewrite code uses __create_pgd_mapping() to create a
temporary pagetable. This happens in atomic context, after secondary
CPUs are brought up and the kernel has left the SYSTEM_BOOTING state.
Hence we try to acquire a mutex in atomic context, which is generally
unsound (though benign in this case as the mutex should be free and all
other CPUs are quiescent).

This patch avoids the issue by pulling the mutex out of alloc_init_pud()
and calling it at a higher level in the pagetable manipulation code.
This allows it to be used without locking where one CPU is known to be
in exclusive control of the machine, even after having left the
SYSTEM_BOOTING state.

efi: libstub: check Shim mode using MokSBStateRT

We currently check the MokSBState variable to decide whether we should
treat UEFI secure boot as being disabled, even if the firmware thinks
otherwise. This is used by shim to indicate that it is not checking
signatures on boot images. In the kernel, we use this to relax lockdown
policies.

However, in cases where shim is not even being used, we don't want this
variable to interfere with lockdown, given that the variable may be
non-volatile and therefore persist across a reboot. This means setting
it once will persistently disable lockdown checks on a given system.

So switch to the mirrored version of this variable, called MokSBStateRT,
which is supposed to be volatile, and this is something we can check.
