drm/amd/display: Remove wrong pipe control lock
When using a device based on DCN32/321,
we have an issue where a second
4k@60Hz display does not light up,
and the system becomes unresponsive
for a few minutes. In the debug process,
it was possible to see a hang
in the function dcn20_post_unlock_program_front_end
in this part:
for (j = 0; j < TIMEOUT_FOR_PIPE_ENABLE_MS*1000
&& hubp->funcs->hubp_is_flip_pending(hubp); j++)
mdelay(1);
}
The hubp_is_flip_pending always returns positive
for waiting pending flips which is a symptom of
pipe hang. Additionally, the dmesg log shows
this message after a few minutes:
BUG: soft lockup - CPU#4 stuck for 26s!
...
[ +0.000003] dcn20_post_unlock_program_front_end+0x112/0x340 [amdgpu]

This confirmed the hypothesis that we had a pipe
hanging somewhere. Next, after checking the
ftrace entries, we have the below weird
sequence:
[..]

2) 0.120 us | optc1_is_tg_enabled [amdgpu]();

We are not expected to read from dmub register
so many times and for so long. From the trace log,
it was possible to identify that the function
dcn20_pipe_control_lock was triggering the dmub
operation when it was unnecessary and causing
the hang issue. This commit drops the unnecessary
dmub code and, consequently, fixes the second display not
lighting up the issue.

drm/i915/dgfx: Keep PCI autosuspend control 'on' by default on all dGPU
DGFX platforms has lmem and cpu can access the lmem objects
via mmap and i915 internal i915_gem_object_pin_map() for
i915 own usages. Both of these methods has pre-requisite
requirement to keep GFX PCI endpoint in D0 for a supported
iomem transaction over PCI link. (Refer PCIe specs 5.3.1.4.1)
Both DG1/DG2 have a known hardware bug that violates the PCIe specs
and support the iomem read write transaction over PCIe bus despite
endpoint is D3 state.
Due to above H/W bug, we had never observed any issue with i915 runtime
PM versus lmem access.
But this issue becomes visible when PCIe gfx endpoint's upstream
bridge enters to D3, at this point any lmem read/write access will be
returned as unsupported request. But again this issue is not observed
on every platform because it has been observed on few host machines
DG1/DG2 endpoint's upstream bridge does not bind with pcieport driver.
which really disables the PCIe power savings and leaves the bridge
at D0 state.
We need a unique interface to read/write from lmem with runtime PM
wakeref protection something similar to intel_uncore_{read, write},
keep autosuspend control to 'on' on all discrete platforms,
until we have a unique interface to read/write from lmem.
This just change the default autosuspend setting of i915 on dGPU,
user can still change it to 'auto'.

- Modified the commit message and subject with more information.
- Changed the Fixes tag to LMEM support commit. [Joonas]
- Changed !HAS_LMEM() Cond to !IS_DGFX(). [Rodrigo]

The KVM_X86_SET_MSR_FILTER ioctls contains a pointer in the passed in

it gets called from 32bit or 64bit code.
This patch introduces compat code that converts from the 32bit struct to
its 64bit counterpart which then gets used going forward internally.
With this applied, 32bit QEMU can successfully set MSR bitmaps when

x86/fpu: Fix copy_xstate_to_uabi() to copy init states correctly
When an extended state component is not present in fpstate, but in init

But, dynamic states are not present in init_fpstate because of all-zeros
init states. Then retrieving them from init_fpstate will explode like this:

Adjust the 'mask' to zero out the userspace buffer for the features that
are not available both from fpstate and from init_fpstate.
The dynamic features depend on the compacted XSAVE format. Ensure it is
enabled before reading XCOMP_BV in init_fpstate.

efi: runtime: Don't assume virtual mappings are missing if VA == PA == 0
The generic EFI stub can be instructed to avoid SetVirtualAddressMap(),
and simply run with the firmware's 1:1 mapping. In this case, it
populates the virtual address fields of the runtime regions in the
memory map with the physical address of each region, so that the mapping
code has to be none the wiser. Only if SetVirtualAddressMap() fails, the
virtual addresses are wiped and the kernel code knows that the regions
cannot be mapped.
However, wiping amounts to setting it to zero, and if a runtime region
happens to live at physical address 0, its valid 1:1 mapped virtual
address could be mistaken for a wiped field, resulting on loss of access
to the EFI services at runtime.
So let's only assume that VA == 0 means 'no runtime services' if the
region in question does not live at PA 0x0.

which UEFI variables affect the boot flow in which way could be moved

This inadvertently broke setting variables on firmware implementations
that lack the QueryVariableInfo() boot service, because we no longer
tolerate a EFI_UNSUPPORTED result from check_var_size() when calling
efivar_entry_set_get_size(), which now ends up calling check_var_size()

efi: libstub: Remove zboot signing from build options
The zboot decompressor series introduced a feature to sign the PE/COFF
kernel image for secure boot as part of the kernel build. This was
necessary because there are actually two images that need to be signed:
the kernel with the EFI stub attached, and the decompressor application.
This is a bit of a burden, because it means that the images must be
signed on the the same system that performs the build, and this is not
realistic for distros.
During the next cycle, we will introduce changes to the zboot code so
that the inner image no longer needs to be signed. This means that the
outer PE/COFF image can be handled as usual, and be signed later in the
release process.
Let's remove the associated Kconfig options now so that they don't end
up in a LTS release while already being deprecated.

iommu/vt-d: Allow NVS regions in arch_rmrr_sanity_check()
arch_rmrr_sanity_check() warns if the RMRR is not covered by an ACPI
Reserved region, but it seems like it should accept an NVS region as
well. The ACPI spec
https://uefi.org/specs/ACPI/6.5/15_System_Address_Map_Interfaces.html
uses similar wording for "Reserved" and "NVS" region types; for NVS
regions it says "This range of addresses is in use or reserved by the
system and must not be used by the operating system."
There is an old comment on this mailing list that also suggests NVS
regions should pass the arch_rmrr_sanity_check() test:
The warnings come from arch_rmrr_sanity_check() since it checks whether
the region is E820_TYPE_RESERVED. However, if the purpose of the check
is to detect RMRR has regions that may be used by OS as free memory,
isn't E820_TYPE_NVS safe, too?
This patch overlaps with another proposed patch that would add the region
type to the log since sometimes the bug reporter sees this log on the
console but doesn't know to include the kernel log:
https://lore.kernel.org/lkml/

nouveau: fix migrate_to_ram() for faulting page
Commit
16ce101db85d ("mm/memory.c: fix race when faulting a device private
page") changed the migrate_to_ram() callback to take a reference on the
device page to ensure it can't be freed while handling the fault.
Unfortunately the corresponding update to Nouveau to accommodate this
change was inadvertently dropped from that patch causing GPU to CPU
migration to fail so add it here.

The problem can be reproduced with the mmtests config
config-workload-stressng-mmap. It does not always happen and when it
triggers is variable but it has happened on multiple machines.
The intent of commit
b653db77350c patch was to avoid the case where
PG_private is clear but folio->private is not-NULL. However, THP tail
pages uses page->private for "swp_entry_t if folio_test_swapcache()" as
stated in the documentation for struct folio. This patch only clobbers
page->private for tail pages if the head page was not in swapcache and
warns once if page->private had an unexpected value.

hugetlb: fix memory leak associated with vma_lock structure
The hugetlb vma_lock structure hangs off the vm_private_data pointer of
sharable hugetlb vmas. The structure is vma specific and can not be
shared between vmas. At fork and various other times, vmas are duplicated
via vm_area_dup(). When this happens, the pointer in the newly created
vma must be cleared and the structure reallocated. Two hugetlb specific
routines deal with this hugetlb_dup_vma_private and hugetlb_vm_op_open.
Both routines are called for newly created vmas. hugetlb_dup_vma_private
would always clear the pointer and hugetlb_vm_op_open would allocate the
new vms_lock structure. This did not work in the case of this calling
sequence pointed out in [1].
move_vma
copy_vma
new_vma = vm_area_dup(vma);
new_vma->vm_ops->open(new_vma); --> new_vma has its own vma lock.
is_vm_hugetlb_page(vma)
clear_vma_resv_huge_pages
hugetlb_dup_vma_private --> vma->vm_private_data is set to NULL
When clearing hugetlb_dup_vma_private we actually leak the associated
vma_lock structure.
The vma_lock structure contains a pointer to the associated vma. This
information can be used in hugetlb_dup_vma_private and hugetlb_vm_op_open
to ensure we only clear the vm_private_data of newly created (copied)
vmas. In such cases, the vma->vma_lock->vma field will not point to the
vma.
Update hugetlb_dup_vma_private and hugetlb_vm_op_open to not clear
vm_private_data if vma->vma_lock->vma == vma. Also, log a warning if
hugetlb_vm_op_open ever encounters the case where vma_lock has already
been correctly allocated for the vma.

cause was traced to an error path in mmap_region when mas_preallocate()

filesystem specific mmap. The hugetlbfs mmap routine may allocate data
structures pointed to by m_private_data. These need to be cleaned up by
the hugetlb vm_ops->close() routine.
The same issue was addressed by commit

inode if __ocfs2_mknod_locked() fails later. But this introduce a race,
the freed bit may be reused immediately by another thread, which will
update dinode, e.g. i_generation. Then iput this inode will lead to BUG:
inode->i_generation != le32_to_cpu(fe->i_generation)
We could make this inode as bad, but we did want to do operations like
wipe in some cases. Since the claimed inode bit can only affect that an
dinode is missing and will return back after fsck, it seems not a big
problem. So just leave it as is by revert the reclaim logic.
