ASoC: cs35l41: Handle mdsync_up reg write errors

[ Upstream commit 4bb5870ab60abca6ad18196090831b5e4cf82d93 ]

The return code of regmap_multi_reg_write() call related to "MDSYNC up"
sequence is shadowed by the subsequent regmap_read_poll_timeout()
invocation, which will hit a timeout in case the write operation above
fails.

Make sure cs35l41_global_enable() returns the correct error code instead
of -ETIMEDOUT.

Additionally, to be able to distinguish between the timeouts of
wait_for_completion_timeout() and regmap_read_poll_timeout(), print an
error message for the former and return immediately.  This also avoids
having to wait unnecessarily for the second time.

module/decompress: use vmalloc() for gzip decompression workspace

[ Upstream commit 3737df782c740b944912ed93420c57344b1cf864 ]

Use a similar approach as commit a419beac4a07 ("module/decompress: use
vmalloc() for zstd decompression workspace") and replace kmalloc() with
vmalloc() also for the gzip module decompression workspace.

In this case the workspace is represented by struct inflate_workspace
that can be fairly large for kmalloc() and it can potentially lead to
allocation errors on certain systems:

$ pahole inflate_workspace
struct inflate_workspace {
struct inflate_state       inflate_state;        /*     0  9544 */
/* --- cacheline 149 boundary (9536 bytes) was 8 bytes ago --- */
unsigned char              working_window[32768]; /*  9544 32768 */

/* size: 42312, cachelines: 662, members: 2 */
/* last cacheline: 8 bytes */
};

Considering that there is no need to use continuous physical memory,
simply switch to vmalloc() to provide a more reliable in-kernel module
decompression.

ARM: dts: BCM5301X: Explicitly disable unused switch CPU ports

[ Upstream commit 473baeab929444295b0530f8766e4becb6a08973 ]

When redescribing ports I assumed that missing "label" (like "cpu")
means switch port isn't used. That was incorrect and I realized my
change made Linux always use the first (5) CPU port (there are 3 of
them).

While above should technically be possible it often isn't correct:
1. Non-default switch ports are often connected to Ethernet interfaces
   not fully covered by vendor setup (they may miss MACs)
2. On some devices non-default ports require specifying fixed link

This fixes network connectivity for some devices. It was reported &
tested for Netgear R8000. It also affects Linksys EA9200 with its
downstream DTS.

firmware: tegra: Add suspend hook and reset BPMP IPC early on resume

[ Upstream commit ea608a01d4ee66f8b51070e623f9adb8684c0dd4 ]

Add suspend hook and a 'suspended' field in the 'struct tegra_bpmp'
to mark if BPMP is suspended. Also, add a 'flags' field in the
'struct tegra_bpmp_message' whose 'TEGRA_BPMP_MESSAGE_RESET' bit can be
set from the Tegra MC driver to signal that the reset of BPMP IPC
channels is required before sending MRQ to the BPMP FW. Together both
the fields allow us to handle any requests that might be sent too soon
as they can cause hang during system resume.

One case where we see BPMP requests being sent before the BPMP driver
has resumed is the memory bandwidth requests which are triggered by
onlining the CPUs during system resume. The CPUs are onlined before the
BPMP has resumed and we need to reset the BPMP IPC channels to handle
these requests.

The additional check for 'flags' is done to avoid any un-intended BPMP
IPC reset if the tegra_bpmp_transfer*() API gets called during suspend
sequence after the BPMP driver is suspended.

An FF-A ABI could support both the SMC32 and SMC64 conventions.
A callee that runs in the AArch64 execution state and implements such

information.

firmware: ti_sci: Mark driver as non removable

[ Upstream commit 7b7a224b1ba1703583b25a3641ad9798f34d832a ]

The TI-SCI message protocol provides a way to communicate between
various compute processors with a central system controller entity. It
provides the fundamental device management capability and clock control
in the SOCs that it's used in.

The remove function failed to do all the necessary cleanup if
there are registered users. Some things are freed however which
likely results in an oops later on.

Ensure that the driver isn't unbound by suppressing its bind and unbind
sysfs attributes. As the driver is built-in there is no way to remove
device once bound.

We can also remove the ti_sci_remove call along with the
ti_sci_debugfs_destroy as there are no callers for it any longer.

kunit: test: Fix the possible memory leak in executor_test

[ Upstream commit 8040345fdae4cb256c5d981f91ae0f22bea8adcc ]

When CONFIG_KUNIT_ALL_TESTS=y, making CONFIG_DEBUG_KMEMLEAK=y and
CONFIG_DEBUG_KMEMLEAK_AUTO_SCAN=y, the below memory leak is detected.

If kunit_filter_suites() succeeds, not only copy but also filtered_suite
and filtered_suite->test_cases should be freed.

So as Rae suggested, to avoid the suite set never be freed when
KUNIT_ASSERT_EQ() fails and exits after kunit_filter_suites() succeeds,
update kfree_at_end() func to free_suite_set_at_end() to use
kunit_free_suite_set() to free them as kunit_module_exit() and
kunit_run_all_tests() do it. As the second arg got of
free_suite_set_at_end() is a local variable, copy it for free to avoid
wild-memory-access. After applying this patch, the following memory leak
is never detected.

kunit: Fix missed memory release in kunit_free_suite_set()

[ Upstream commit a6074cf0126b0bee51ab77a15930dc24a4d5db90 ]

modprobe cpumask_kunit and rmmod cpumask_kunit, kmemleak detect
a suspected memory leak as below.

If kunit_filter_suites() in kunit_module_init() succeeds, the
suite_set.start will not be NULL and the kunit_free_suite_set() in
kunit_module_exit() should free all the memory which has not
been freed. However the test_cases in suites is left out.

[ Upstream commit 39c8af78cbefb8c71a5ad1fa088e761ef418f0a0 ]

Qualcomm Embedded USB Debugger (EUD) second port should point to Type-C
USB connector.  Such connector was defined directly in root node of
sc7280.dtsi which is clearly wrong.  SC7280 is a chip, so physically it
does not have USB Type-C port.  The connector is usually accessible
through some USB switch or controller.

Doug Anderson said that he wasn't ever able to use EUD on Herobrine
boards, probably because of invalid or missing DTS description - DTS is
saying EUD is on usb_2 node, which is connected to a USB Hub, not to the
Type-C port.

Correct the EUD/USB connector topology by removing the top-level fake
USB connector and EUD port pointing to it, and disabling the incomplete
EUD device node.

This fixes also dtbs_check warnings:

drm: mediatek: mtk_dsi: Fix NO_EOT_PACKET settings/handling

[ Upstream commit 5855d422a6f250f3518f43b49092c8e87a5e42be ]

Due to the initial confusion about MIPI_DSI_MODE_EOT_PACKET, properly
renamed to MIPI_DSI_MODE_NO_EOT_PACKET, reflecting its actual meaning,
both the DSI_TXRX_CON register setting for bit (HSTX_)DIS_EOT and the
later calculation for horizontal sync-active (HSA), back (HBP) and
front (HFP) porches got incorrect due to the logic being inverted.

This means that a number of settings were wrong because....:
 - DSI_TXRX_CON register setting: bit (HSTX_)DIS_EOT should be
   set in order to disable the End of Transmission packet;
 - Horizontal Sync and Back/Front porches: The delta used to
   calculate all of HSA, HBP and HFP should account for the
   additional EOT packet.

Before this change...
 - Bit (HSTX_)DIS_EOT was being set when EOT packet was enabled;
 - For HSA/HBP/HFP delta... all three were wrong, as words were
   added when EOT disabled, instead of when EOT packet enabled!

Invert the logic around flag MIPI_DSI_MODE_NO_EOT_PACKET in the
MediaTek DSI driver to fix the aforementioned issues.

clocksource/drivers/arm_arch_timer: limit XGene-1 workaround

[ Upstream commit 851354cbd12bb9500909733c3d4054306f61df87 ]

The AppliedMicro XGene-1 CPU has an erratum where the timer condition
would only consider TVAL, not CVAL. We currently apply a workaround when
seeing the PartNum field of MIDR_EL1 being 0x000, under the assumption
that this would match only the XGene-1 CPU model.
However even the Ampere eMAG (aka XGene-3) uses that same part number, and
only differs in the "Variant" and "Revision" fields: XGene-1's MIDR is
0x500f0000, our eMAG reports 0x503f0002. Experiments show the latter
doesn't show the faulty behaviour.

Increase the specificity of the check to only consider partnum 0x000 and
variant 0x00, to exclude the Ampere eMAG.

drm/msm/dsi: free TX buffer in unbind

[ Upstream commit 5e05be78264594634860087953649487f486ffcc ]

If the drm/msm init code gets an error during output modeset
initialisation, the kernel will report an error regarding DRM memory
manager not being clean during shutdown. This is because
msm_dsi_modeset_init() allocates a piece of GEM memory for the TX
buffer, but destruction of the buffer happens only at
msm_dsi_host_destroy(), which is called during DSI driver's remove()
time, much later than the DRM MM shutdown.

To solve this issue, move the TX buffer destruction to dsi_unbind(), so
that the buffer is destructed at the correct time. Note, we also have to
store a reference to the address space, because priv->kms->aspace is
cleared before components are unbound.

xen-pciback: Consider INTx disabled when MSI/MSI-X is enabled

[ Upstream commit 2c269f42d0f382743ab230308b836ffe5ae9b2ae ]

Linux enables MSI-X before disabling INTx, but keeps MSI-X masked until
the table is filled. Then it disables INTx just before clearing MASKALL
bit. Currently this approach is rejected by xen-pciback.
According to the PCIe spec, device cannot use INTx when MSI/MSI-X is
enabled (in other words: enabling MSI/MSI-X implicitly disables INTx).

Change the logic to consider INTx disabled if MSI/MSI-X is enabled. This
applies to three places:
 - checking currently enabled interrupts type,
 - transition to MSI/MSI-X - where INTx would be implicitly disabled,
 - clearing INTx disable bit - which can be allowed even if MSI/MSI-X is
   enabled, as device should consider INTx disabled anyway in that case

requires that this is always a valid VA, which we cannot guarantee. Due
to this, xen_starting_cpu() must avoid registering each CPU's runstate
region, and xen_guest_init() must avoid setting up features that depend
upon it.

We tried to ensure that in commit:

  f88af7229f6f22ce (" xen/arm: do not setup the runstate info page if kpti is enabled")

... where we added checks for xen_kernel_unmapped_at_usr(), which wraps
arm64_kernel_unmapped_at_el0() on arm64 and is always false on 32-bit
arm.

Unfortunately, as xen_guest_init() is an early_initcall, this happens
before secondary CPUs are booted and arm64 has finalized the
ARM64_UNMAP_KERNEL_AT_EL0 cpucap which backs
arm64_kernel_unmapped_at_el0(), and so this can subsequently be set as
secondary CPUs are onlined. On a big.LITTLE system where the boot CPU
does not require KPTI but some secondary CPUs do, this will result in
xen_guest_init() intializing features that depend on the runstate
region, and xen_starting_cpu() registering the runstate region on some
CPUs before KPTI is subsequent enabled, resulting the the problems the
aforementioned commit tried to avoid.

Handle this more robsutly by deferring the initialization of the
runstate region until secondary CPUs have been initialized and the
ARM64_UNMAP_KERNEL_AT_EL0 cpucap has been finalized. The per-cpu work is
moved into a new hotplug starting function which is registered later
when we're certain that KPTI will not be used.

drm/bridge: lt9611uxc: fix the race in the error path

[ Upstream commit 15fe53be46eaf4f6339cd433972ecc90513e3076 ]

If DSI host attachment fails, the LT9611UXC driver will remove the
bridge without ensuring that there is no outstanding HPD work being
done. In rare cases this can result in the warnings regarding the mutex
being incorrect. Fix this by forcebly freing IRQ and flushing the work.

drm/msm/a6xx: Fix unknown speedbin case

[ Upstream commit 75cb60d4f5f762b12643b67cbefefcf05ecfd7eb ]

When opp-supported-hw is present under an OPP node, but no form of
opp_set_supported_hw() has been called, that OPP is ignored by the API
and marked as unsupported.

Before Commit c928a05e4415 ("drm/msm/adreno: Move speedbin mapping to
device table"), an unknown speedbin would result in marking all OPPs
as available, but it's better to avoid potentially overclocking the
silicon - the GMU will simply refuse to power up the chip.

Currently, the Adreno speedbin code does just that (AND returns an
invalid error, (int)UINT_MAX). Fix that by defaulting to speedbin 0
(which is conveniently always bound to fuseval == 0).

drm/mediatek: Fix iommu fault during crtc enabling

[ Upstream commit 53412dc2905401207f264dc30890f6b9e41524a6 ]

The difference between drm_atomic_helper_commit_tail() and
drm_atomic_helper_commit_tail_rpm() is
drm_atomic_helper_commit_tail() will commit plane first and
then enable crtc, drm_atomic_helper_commit_tail_rpm() will
enable crtc first and then commit plane.

Before mediatek-drm enables crtc, the power and clk required
by OVL have not been turned on, so the commit plane cannot be
committed before crtc is enabled. That means OVL layer should
not be enabled before crtc is enabled.
Therefore, the atomic_commit_tail of mediatek-drm is hooked with
drm_atomic_helper_commit_tail_rpm().

Another reason is that the plane_state of drm_atomic_state is not
synchronized with the plane_state stored in mtk_crtc during crtc enablng,
so just set all planes to disabled.

drm/mediatek: Fix iommu fault by swapping FBs after updating plane state

drm/amdkfd: fix some race conditions in vram buffer alloc/free of svm code

[ Upstream commit 7bfaa160caed8192f8262c4638f552cad94bcf5a ]

This patch fixes:
1: ref number of prange's svm_bo got decreased by an async call from hmm. When
wait svm_bo of prange got released we shoul also wait prang->svm_bo become NULL,
otherwise prange->svm_bo may be set to null after allocate new vram buffer.

2: During waiting svm_bo of prange got released in a while loop should reschedule
current task to give other tasks oppotunity to run, specially the the workque
task that handles svm_bo ref release, otherwise we may enter to softlock.

drm: Call drm_atomic_helper_shutdown() at shutdown/remove time for misc drivers

[ Upstream commit 3c4babae3c4a1ae05f8f3f5f3d50c440ead7ca6a ]

Based on grepping through the source code these drivers appear to be
missing a call to drm_atomic_helper_shutdown() at system shutdown time
and at driver remove (or unbind) time. Among other things, this means
that if a panel is in use that it won't be cleanly powered off at
system shutdown time.

The fact that we should call drm_atomic_helper_shutdown() in the case
of OS shutdown/restart and at driver remove (or unbind) time comes
straight out of the kernel doc "driver instance overview" in
drm_drv.c.

A few notes about these fixes:
- I confirmed that these drivers were all DRIVER_MODESET type drivers,
  which I believe makes this relevant.
- I confirmed that these drivers were all DRIVER_ATOMIC.
- When adding drm_atomic_helper_shutdown() to the remove/unbind path,
  I added it after drm_kms_helper_poll_fini() when the driver had
  it. This seemed to be what other drivers did. If
  drm_kms_helper_poll_fini() wasn't there I added it straight after
  drm_dev_unregister().
- This patch deals with drivers using the component model in similar
  ways as the patch ("drm: Call drm_atomic_helper_shutdown() at
  shutdown time for misc drivers")
- These fixes rely on the patch ("drm/atomic-helper:
  drm_atomic_helper_shutdown(NULL) should be a noop") to simplify
  shutdown.

to clock periods. The original author does not remember where all this
came from. Effectively the driver is using picoseconds as the unit for

drm/bridge: tc358768: Rename dsibclk to hsbyteclk

[ Upstream commit 699cf62a7d4550759f4a50e614b1952f93de4783 ]

The Toshiba documentation talks about HSByteClk when referring to the
DSI HS byte clock, whereas the driver uses 'dsibclk' name. Also, in a
few places the driver calculates the byte clock from the DSI clock, even
if the byte clock is already available in a variable.

To align the driver with the documentation, change the 'dsibclk'
variable to 'hsbyteclk'. This also make it easier to visually separate
'dsibclk' and 'dsiclk' variables.

x86/tdx: Zero out the missing RSI in TDX_HYPERCALL macro

[ Upstream commit 5d092b66119d774853cc9308522620299048a662 ]

In the TDX_HYPERCALL asm, after the TDCALL instruction returns from the
untrusted VMM, the registers that the TDX guest shares to the VMM need
to be cleared to avoid speculative execution of VMM-provided values.

RSI is specified in the bitmap of those registers, but it is missing
when zeroing out those registers in the current TDX_HYPERCALL.

It was there when it was originally added in commit 752d13305c78
("x86/tdx: Expand __tdx_hypercall() to handle more arguments"), but was
later removed in commit 1e70c680375a ("x86/tdx: Do not corrupt
frame-pointer in __tdx_hypercall()"), which was correct because %rsi is
later restored in the "pop %rsi".  However a later commit 7a3a401874be
("x86/tdx: Drop flags from __tdx_hypercall()") removed that "pop %rsi"
but forgot to add the "xor %rsi, %rsi" back.

Fix by adding it back.
