The existing NOCODEC mode enforces a build-time mutual exclusion with
the HDaudio link support, mostly to avoid any dependency on the
snd_hdac library and references to HDAudio codec/i915 stuff.
This is very useful to track dependencies and test a minimal
configuration, but very painful for developers and CI: a recompilation
and reinstall of the kernel modules is required.
This patch suggests an alternate middle ground where the selection of
the machine driver and all codec-related actions are bypassed at
run-time, contingent on a kernel module parameter being set.
For example setting BIT(10) with
'options snd_sof sof_debug=0x401'
is enough to switch from an HDaudio card to a nocodec one.
This new DEBUG_NOCODEC mode is not suitable for distributions and
end-users. It's not even recommended on all platforms, i.e. the
NOCODEC mode is known not to work on specific devices where the BIOS
did not configure support for I2S/DMIC interfaces. The usual
development devices such as Chromebooks, Up boards and Intel RVP are
the only recommended platforms where this mode can be supported.
Note that the dynamic switch between HDaudio and nocodec may not
always possible depending on hardware layout, pin-mux options, and
BIOS settings. The audio subsustems on Intel platforms has to support
4 types of interfaces and pin-mux can be complicated.
Reviewers might ask: why didn't we do this earlier? The main reason is
that all the codec-related configurations were not cleanly separated
out in the sof/intel directory. With all the cleanups done recently,
adding this opt-in behavior is relatively straightforward.
Tested on UpExtreme (WHL) and UpExtreme i11 (TGL).

All the HDAudio codec handling is completely specific to Linux and
completely dependency on GPL2.0 code, specifically the snd_hdac_
library.
There was no intention to have a dual-license for this code, this was
an oversight that needs to be corrected. Update the SPDX and
EXPORT_SYMBOL information, no functionality change otherwise.

Implement suspend/resume() operations for component drivers. For most
scenarios, the PM flow is similar to standard streaming one, except for
the part where the position register are being saved and the lack of PCM
pages freeing. To reduce code duplication, all avs_dai_suspend_XXX() and
avs_dai_resume_XXX() functions reuse their non-PM equivalents.
Given that path binding/unbinding happens only in FE part of the stream,
the order of suspend() goes:
1. hw_free() all FE DAIs, paths are unbound here
2. hw_free() all BE DAIs
Consequently, for resume() its:
1. hw_params() all BE DAIs
2. hw_params() all FE DAIs, paths are bound here
3. prepare() all BE DAIs
4. prepare() all FE DAIs
As component->suspend/resume() do not provide substream pointer, store
it ourselves so that the PM flow has all the necessary information to
proceed.

The bus->clk_stop_timeout member is only initialized to a non-zero value
during the codec driver probe. This can lead to corner cases where this
value remains pegged at zero when the bus suspends, which results in an
endless loop in sdw_bus_wait_for_clk_prep_deprep().
Corner cases include configurations with no codecs described in the
firmware, or delays in probing codec drivers.
Initializing the default timeout to the smallest non-zero value avoid this
problem and allows for the existing logic to be preserved: the
bus->clk_stop_timeout is set as the maximum required by all codecs
connected on the bus.

In cap_inode_getsecurity(), we will use vfs_getxattr_alloc() to
complete the memory allocation of tmpbuf, if we have completed
the memory allocation of tmpbuf, but failed to call handler->get(...),
there will be a memleak in below logic:
|-- ret = (int)vfs_getxattr_alloc(mnt_userns, ...)
| /* ^^^ alloc for tmpbuf */
|-- value = krealloc(*xattr_value, error + 1, flags)
| /* ^^^ alloc memory */
|-- error = handler->get(handler, ...)
| /* error! */
|-- *xattr_value = value
| /* xattr_value is &tmpbuf (memory leak!) */
So we will try to free(tmpbuf) after vfs_getxattr_alloc() fails to fix it.

On 64 bit host, if the guest doesn't have X86_FEATURE_LM, KVM will
access 16 gprs to 32-bit smram image, causing out-ouf-bound ram
access.
On 32 bit host, the rsm_load_state_64/enter_smm_save_state_64
is compiled out, thus access overflow can't happen.

Update the emulation mode when handling writes to CR0, because
toggling CR0.PE switches between Real and Protected Mode, and toggling
CR0.PG when EFER.LME=1 switches between Long and Protected Mode.
This is likely a benign bug because there is no writeback of state,
other than the RIP increment, and when toggling CR0.PE, the CPU has
to execute code from a very low memory address.

Update the emulation mode after RSM so that RIP will be correctly
written back, because the RSM instruction can switch the CPU mode from
32 bit (or less) to 64 bit.
This fixes a guest crash in case the #SMI is received while the guest
runs a code from an address > 32 bit.

Some instructions update the cpu execution mode, which needs to update the
emulation mode.
Extract this code, and make assign_eip_far use it.
assign_eip_far now reads CS, instead of getting it via a parameter,
which is ok, because callers always assign CS to the same value
before calling this function.
No functional change is intended.

SYSEXIT is one of the instructions that can change the
processor mode, thus ctxt->mode should be updated after it.
Note that this is likely a benign bug, because the only problematic
mode change is from 32 bit to 64 bit which can lead to truncation of RIP,
and it is not possible to do with sysexit,
since sysexit running in 32 bit mode will be limited to 32 bit version.

Tag "guest_saw_irq" as "volatile" to ensure that the compiler will never
optimize away lookups. Relying on the compiler thinking that the flag
is global and thus might change also works, but it's subtle, less robust,
and looks like a bug at first glance, e.g. risks being "fixed" and
breaking the test.
Make the flag "static" as well since convincing the compiler it's global
is no longer necessary.
Alternatively, the flag could be accessed with {READ,WRITE}_ONCE(), but
literally every access would need the wrappers, and eking out performance
isn't exactly top priority for selftests.

Tests for races between shinfo_cache (de)activation and hypercall+ioctl()
processing. KVM has had bugs where activating the shared info cache
multiple times and/or with concurrent users results in lock corruption,
NULL pointer dereferences, and other fun.
For the timer injection testcase (#22), re-arm the timer until the IRQ
is successfully injected. If the timer expires while the shared info
is deactivated (invalid), KVM will drop the event.

There is a limit to eDMA AXI on i.MX93. Only TCD that has NBYTES in a
multiple of 8bytes can enable scatter-gather. NBYTES is calculated by
bus width times maxburst. On i.MX93 platform the value of maxburst is
specified to 8. It makes sure that NBYTES is a multiple of 8bytes.

kmemleak reported memory leaks in dsa_loop_init():
kmemleak: 12 new suspected memory leaks
unreferenced object 0xffff8880138ce000 (size 2048):
comm "modprobe", pid 390, jiffies 4295040478 (age 238.976s)
backtrace:

...
There are two reasons for memleak in dsa_loop_init().
First, fixed_phy_register() create and register phy_device:
fixed_phy_register()
get_phy_device()
phy_device_create() # freed by phy_device_free()
phy_device_register() # freed by phy_device_remove()
But fixed_phy_unregister() only calls phy_device_remove().
So the memory allocated in phy_device_create() is leaked.
Second, when mdio_driver_register() fail in dsa_loop_init(),
it just returns and there is no cleanup for phydevs.
Fix the problems by catching the error of mdio_driver_register()
in dsa_loop_init(), then calling both fixed_phy_unregister() and
phy_device_free() to release phydevs.
Also add a function for phydevs cleanup to avoid duplacate.
