The xdp_frame structure takes up part of the XDP frame headroom,
limiting the size of the metadata. However, in bpf_test_run, we don't
take this into account, which makes it possible for userspace to supply
a metadata size that is too large (taking up the entire headroom).
If userspace supplies such a large metadata size in live packet mode,
the xdp_update_frame_from_buff() call in xdp_test_run_init_page() call
will fail, after which packet transmission proceeds with an
uninitialised frame structure, leading to the usual Bad Stuff.
The commit in the Fixes tag fixed a related bug where the second check
in xdp_update_frame_from_buff() could fail, but did not add any
additional constraints on the metadata size. Complete the fix by adding
an additional check on the metadata size. Reorder the checks slightly to
make the logic clearer and add a comment.

Re-shuffle the logic in the error path of the init task to make sure the
netdevs remain intact. This will allow the driver to attempt recovery via
subsequent resets, provided the FW is still functional.
The main change is to make sure that idpf_decfg_netdev() is not called
should the init task fail during a reset. The error handling is
consolidated under unwind_vports, as the removed labels had the same
cleanup logic split depending on the point of failure.

The current mapping incorrectly includes the addresses of multiple

been detected by the DT tooling as none of the extra mapped IP is

The driver_override_show() function reads the driver_override string
without holding the device_lock. However, driver_override_store() uses
driver_set_override(), which modifies and frees the string while holding
the device_lock.
This can result in a concurrent use-after-free if the string is freed
by the store function while being read by the show function.
Fix this by holding the device_lock around the read operation.

The P66's device tree includes the reference design dtsi files, which
defines a node and properties for the touchpanel in the common design.
The P66 dts file then overrides all the properties to match its own
design, but as the touchpanel model is different, a different schema
is matched. This other schema uses a different name for the GPIO.
The original submission added the correct GPIO property, but did not
delete the one inherited from the reference design, causing validation
errors.
Explicitly delete the incorrect GPIO property.

At SUSE we've been releasing our kernels with TSX enabled for the past 6
years and some customers have started to rely on it. Furthermore, the last
known vulnerability concerning TSX was TAA (CVE-2019-11135) and a
significant amount time has passed since then without anyone reporting any
issues. Intel has released numerous processors which do not have the
TAA vulnerability (Cooper/Ice Lake, Sapphire/Emerald/Granite Rappids)
yet TSX remains being disabled by default.
The main aim of this patch is to reduce the divergence between SUSE's
configuration and the upstream by switching the default TSX mode to
auto. I believe this strikes the right balance between keeping it
enabled where appropriate (i.e every machine which doesn't contain the
TAA vulnerability) and disabling it preventively.

This symbol was removed in early 2025 but 2 dangling references to it
were missed. Delete them now.
It should be safe to drop the -mtune=generic32 option since gcc 4.3
and later do not cause the problem (see 28f7e66fc1da ("x86: prevent
binutils from being "smart" and generating NOPLs for us")). Also, Arnd
confirmed this with gcc-8 and gcc-15 (see Link:).

Direct URLs to vendor specifications for Intel VT-d and AMD IOMMU
are frequently changed by vendors, leading to broken links in the
documentation.
Replace the fragile URLs with persistent identifiers, providing the
official document titles and IDs. This ensures users can locate the
relevant specifications regardless of vendor website restructuring.

The PPU flop reset is required on some hardware to clear the
temporary registers. This code follows the implementation
of the PPU flop reset as found in the public galcore kernel
module. Compared to that code some superfluous parts were
removed and only the code path for SoC chip_model = 0x8000
and revision = 0x6205 is implemented and tested.
v2: - Move flop reset data to etnaviv_drm_private and initialize it
from etnaviv_gpu_bind (Lucas)
- Prepare code for more chip IDs and other flop reset types
- Do some cleanups and rename some functions
v3: - Move initialization of flop reset data to etnaviv_gpu_init (Lucas)
- Free PPU data suballocation (Lucas)
v4: As suggested by
- replace "asm-generic/int-ll64.h" with "linux/types.h"
- drop flop reset type enum since we only support one type here
- move function return parameters on same line with function name
- replace open coded for loop with memset32
- add cnost to local static values
- add a return value to etnaviv_flop_reset_ppu_init; handle and
pass errors on to the caller
- handle etnaviv_flop_reset_ppu_init return value
- use dev_err for flop reset error message
- fix include guard to be consistent with the other driver code
- fix license header and formatting
v5: As suggested by Christian Gmeiner:
- add required header that is no longer pulled in by etnaviv_buffer.h
- fix include style of linux headers
- free flop_reset_data_ppu when command buffer initialization fails
- fix typo in error message
[cgmeiner: fix SPDX comment style, fix line end with a '(' and fix typo]
