struct drm_display_mode embeds a list head, so overwriting
the full struct with another one will corrupt the list
(if the destination mode is on a list). Use drm_mode_copy()
instead which explicitly preserves the list head of
the destination mode.
Even if we know the destination mode is not on any list
using drm_mode_copy() seems decent as it sets a good
example. Bad examples of not using it might eventually
get copied into code where preserving the list head
actually matters.
Obviously one case not covered here is when the mode
itself is embedded in a larger structure and the whole
structure is copied. But if we are careful when copying
into modes embedded in structures I think we can be a
little more reassured that bogus list heads haven't been
propagated in.

A portion of device memory is reserved for Flat CCS so usable
device memory will be reduced by size of Flat CCS. Size of
Flat CCS is specified in “XEHPSDV_FLAT_CCS_BASE_ADDR”.
So to get effective device memory we need to subtract
total device memory by Flat CCS memory size.

Platforms of XeHP and beyond support 3D surface (buffer) compression and
various compression formats. This is accomplished by an additional
compression control state (CCS) stored for each surface.
Gen 12 devices(TGL family and DG1) stores compression states in a separate
region of memory. It is managed by user-space and has an associated set of
user-space managed page tables used by hardware for address translation.
In Xe HP and beyond (XEHPSDV, DG2, etc), there is a new feature introduced
i.e Flat CCS. It replaced AUX page tables with a flat indexed region of
device memory for storing compression states.

First the simplest ones:
- iosys_map_memset(): when abstracting system and I/O memory,
just like the memcpy() use case, memset() also has dedicated
functions to be called for using IO memory.
- iosys_map_memcpy_from(): we may need to copy data from I/O
memory, not only to.
In certain situations it's useful to be able to read or write to an
offset that is calculated by having the memory layout given by a struct
declaration. Usually we are going to read/write a u8, u16, u32 or u64.
As a pre-requisite for the implementation, add iosys_map_memcpy_from()
to be the equivalent of iosys_map_memcpy_to(), but in the other
direction. Then add 2 pairs of macros:
- iosys_map_rd() / iosys_map_wr()
- iosys_map_rd_field() / iosys_map_wr_field()
The first pair takes the C-type and offset to read/write. The second
pair uses a struct describing the layout of the mapping in order to
calculate the offset and size being read/written.
We could use readb, readw, readl, readq and the write* counterparts,
however due to alignment issues this may not work on all architectures.
If alignment needs to be checked to call the right function, it's not
possible to decide at compile-time which function to call: so just leave
the decision to the memcpy function that will do exactly that.
Finally, in order to use the above macros with a map derived from
another, add another initializer: IOSYS_MAP_INIT_OFFSET().
v2:
- Rework IOSYS_MAP_INIT_OFFSET() so it doesn't rely on aliasing rules
within the union
- Add offset to both iosys_map_rd_field() and iosys_map_wr_field() to
allow the struct itself to be at an offset from the mapping
- Add documentation to iosys_map_rd_field() with example and expected
memory layout
v3:
- Drop kernel.h include as it's not needed anymore

DG2 supports a 5th display output which the hardware refers to as "TC1,"
even though it isn't a Type-C output. This behaves similarly to the TC1
on past platforms with just a couple minor differences:
* DG2's TC1 bit in SDEISR is at bit 25 rather than 24 as it is on
ICP/TGP/ADP.
* DG2 doesn't need the hpd inversion setting that we had to use on DG1

If the only thing that is changing is SAGV vs. no SAGV but
the number of active planes and the total data rates end up
unchanged we currently bail out of intel_bw_atomic_check()
early and forget to actually compute the new WGV point
mask and thus won't actually enable/disable SAGV as requested.
This ends up poorly if we end up running with SAGV enabled

BIOS may leave a TypeC PHY in a connected state even though the
corresponding port is disabled. This will prevent any hotplug events
from being signalled (after the monitor deasserts and then reasserts its
HPD) until the PHY is disconnected and so the driver will not detect a
connected sink. Rebooting with the PHY in the connected state also
results in a system hang.
Fix the above by disconnecting TypeC PHYs on disabled ports.
Before commit 64851a32c463e5 the PHY connected state was read out even
for disabled ports and later the PHY got disconnected as a side effect
of a tc_port_lock/unlock() sequence (during connector probing), hence
recovering the port's hotplug functionality.

workaround list and need to be moved accordingly. We also have one
workaround (Wa_22012532006) that is incorrectly implemented on the
context workaround list, even though the register it is adjusting is not
part of the RCS engine's context image; it must also be moved.
We'll have some workaround refactoring coming in the near future that
deals with registers in the reset domain in a more clear way. But in
the meantime, we should just move these workarounds to
rcs_engine_wa_init() to place them on the RCS engine's workaround list.
All production DG2 platforms will have an RCS engine (it's never fused
off) so these registers will be properly restored after a domain reset
triggered via an RCS engine _or_ a CCS engine.

Clang warns:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_packet_manager_v9.c:267:3:
error: implicit conversion from enumeration type 'enum

Use 'extended_engine_sel__mes_unmap_queues__sdma0_to_7_sel' to eliminate
the warning, which is the same numeric value of the proper type.

Clang build fails with
amdgpu_ras.c:2416:7: error: variable 'ras_obj' is used uninitialized
whenever 'if' condition is true
if (adev->in_suspend || amdgpu_in_reset(adev)) {

There is a logic error in the error handler's labels.
ex/ The sysfs: is the last goto label in the normal code but
is the middle of error handler. Rework the error handler.
cleanup: is the first error, so it's handler should be last.
interrupt: is the second error, it's handler is next. interrupt:
handles the failure of amdgpu_ras_interrupt_add_hander() by
calling amdgpu_ras_interrupt_remove_handler(). This is wrong,
remove() assumes the interrupt has been setup, not torn down by
add(). Change the goto label to cleanup.
sysfs is the last error, it's handler should be first. sysfs:
handles the failure of amdgpu_ras_sysfs_create() by calling
amdgpu_ras_sysfs_remove(). But when the create() fails there
is nothing added so there is nothing to remove. This error
handler is not needed. Remove the error handler and change
goto label to interrupt.

The `program_aspm` callback is already guarded for aspm, but the
`enable_aspm` callback doesn't follow the module parameter.
Update it to use the helper `amdgpu_device_should_use_aspm`.

Evaluating `pcie_aspm_enabled` as part of driver probe has the implication
that if one PCIe bridge with an AMD GPU connected doesn't support ASPM
then none of them do. This is an invalid assumption as the PCIe core will
configure ASPM for individual PCIe bridges.
Create a new helper function that can be called by individual dGPUs to
react to the `amdgpu_aspm` module parameter without having negative results
for other dGPUs on the PCIe bus.
