Set the default workload type to bootup type on smu v13.0.7.
This is because of the constraint on smu v13.0.7.
Gfx activity has an even higher set point on 3D fullscreen
mode than the one on bootup mode. This causes the 3D fullscreen
mode's performance is worse than the bootup mode's performance
for the lightweighted/medium workload. For the high workload,
the performance is the same between 3D fullscreen mode and bootup
mode.
v2: set the default workload in ASIC specific file

On the Raspberry Pi 5, performance counters are not being cleared
when `v3d_perfmon_start()` is called, even though we write to the
CLR register. As a result, their values accumulate until they
overflow.
The expected behavior is for performance counters to reset to zero
at the start of a job. When the job finishes and the perfmon is
stopped, the counters should accurately reflect the values for that
specific job.
To ensure this behavior, the performance counters are now enabled
before being cleared. This allows the CLR register to function as
intended, zeroing the counter values when the job begins.

If the MST topology is removed during the reception of an MST down reply
or MST up request sideband message, the
drm_dp_mst_topology_mgr::up_req_recv/down_rep_recv states could be reset
from one thread via drm_dp_mst_topology_mgr_set_mst(false), racing with
the reading/parsing of the message from another thread via
drm_dp_mst_handle_down_rep() or drm_dp_mst_handle_up_req(). The race is
possible since the reader/parser doesn't hold any lock while accessing
the reception state. This in turn can lead to a memory corruption in the
reader/parser as described by commit bd2fccac61b4 ("drm/dp_mst: Fix MST
sideband message body length check").
Fix the above by resetting the message reception state if needed before
reading/parsing a message. Another solution would be to hold the
drm_dp_mst_topology_mgr::lock for the whole duration of the message
reception/parsing in drm_dp_mst_handle_down_rep() and
drm_dp_mst_handle_up_req(), however this would require a bigger change.
Since the fix is also needed for stable, opting for the simpler solution
in this patch.

Commit 255fc1703e42 ("drm/i915/gem: Calculate object page offset for
partial memory mapping") introduced a new offset, which accounts for
userspace mapping not starting from the beginning of object's scatterlist.
This works fine for cases where first object pte is larger than the new
offset - "r->sgt.curr" counter is set to the offset to match the difference
in the number of total pages. However, if object's first pte's size is
equal to or smaller than the offset, then information about the offset
in userspace is covered up by moving "r->sgt" pointer in remap_sg():
r->sgt.curr += PAGE_SIZE;
if (r->sgt.curr >= r->sgt.max)
r->sgt = __sgt_iter(__sg_next(r->sgt.sgp), use_dma(r->iobase));
This means that two or more pages from virtual memory are counted for
only one page in object's memory, because after moving "r->sgt" pointer
"r->sgt.curr" will be 0.
We should account for this mismatch by moving "r->sgt" pointer to the
next pte. For that we may use "r.sgt.max", which already holds the max
allowed size. This change also eliminates possible confusion, when
looking at i915_scatterlist.h and remap_io_sg() code: former has
scatterlist pointer definition, which differentiates "s.max" value
based on "dma" flag (sg_dma_len() is used only when the flag is
enabled), while latter uses sg_dma_len() indiscriminately.
This patch aims to resolve issue:
https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/12031
v3:
- instead of checking if r.sgt.curr would exceed allowed max, changed
the value in the while loop to be aligned with `dma` value
v4:
- remove unnecessary parent relation
v5:
- update commit message with explanation about page counting mismatch
and link to the issue

The LOGINIT, LOGINTR, LOGRM, and LOGPMU buffers are circular buffers
that have printf-like logs from GSP-RM and PMU encoded in them.
LOGINIT, LOGINTR, and LOGRM are allocated by Nouveau and their DMA
addresses are passed to GSP-RM during initialization. The buffers are
required for GSP-RM to initialize properly.
LOGPMU is also allocated by Nouveau, but its contents are updated
when Nouveau receives an NV_VGPU_MSG_EVENT_UCODE_LIBOS_PRINT RPC from
GSP-RM. Nouveau then copies the RPC to the buffer.
The messages are encoded as an array of variable-length structures that
contain the parameters to an NV_PRINTF call. The format string and
parameter count are stored in a special ELF image that contains only
logging strings. This image is not currently shipped with the Nvidia
driver.
There are two methods to extract the logs.
OpenRM tries to load the logging ELF, and if present, parses the log
buffers in real time and outputs the strings to the kernel console.
Alternatively, and this is the method used by this patch, the buffers
can be exposed to user space, and a user-space tool (along with the
logging ELF image) can parse the buffer and dump the logs.
This method has the advantage that it allows the buffers to be parsed
even when the logging ELF file is not available to the user. However,
it has the disadvantage the debugfs entries need to remain until the
driver is unloaded.
The buffers are exposed via debugfs. If GSP-RM fails to initialize, then
Nouveau immediately shuts down the GSP interface. This would normally
also deallocate the logging buffers, thereby preventing the user from
capturing the debug logs.
To avoid this, introduce the keep-gsp-logging command line parameter. If
specified, and if at least one logging buffer has content, then Nouveau
will migrate these buffers into new debugfs entries that are retained
until the driver unloads.
An end-user can capture the logs using the following commands:
cp /sys/kernel/debug/nouveau/<path>/loginit loginit
cp /sys/kernel/debug/nouveau/<path>/logrm logrm
cp /sys/kernel/debug/nouveau/<path>/logintr logintr
cp /sys/kernel/debug/nouveau/<path>/logpmu logpmu
where (for a PCI device) <path> is the PCI ID of the GPU (e.g.
0000:65:00.0).
Since LOGPMU is not needed for normal GSP-RM operation, it is only
created if debugfs is available. Otherwise, the
NV_VGPU_MSG_EVENT_UCODE_LIBOS_PRINT RPCs are ignored.
A simple way to test the buffer migration feature is to have
nvkm_gsp_init() return an error code.

Store the struct device pointer used to allocate the DMA buffer in
the nvkm_gsp_mem object. This allows nvkm_gsp_mem_dtor() to release
the buffer without needing the nvkm_gsp. This is needed so that
we can retain DMA buffers even after the nvkm_gsp object is deleted.

Typically DRM drivers use the DRM debugfs root entry. However, since
Nouveau is heading towards a split into a core and a DRM driver, create
a module specific debugfs root directory.
Subsequent patches make use of this new debugfs root in order to store
GSP-RM log bufferes (optionally beyond a device driver binding).

There is a HW issue that arises when there are race conditions
between TCSS entering/exiting TC7 or TC10 states while the
driver is asserting/deasserting TCSS power request. As a
workaround, Display driver will implement a mailbox sequence
to ensure that the TCSS is in TC0 when TCSS power request is
asserted/deasserted.
The sequence is the following
1. Read mailbox command status and wait until run/busy bit is
clear
2. Write mailbox data value '1' for power request asserting
and '0' for power request deasserting
3. Write mailbox command run/busy bit and command value with 0x1
4. Read mailbox command and wait until run/busy bit is clear
before continuing power request.
v2: Rename WA function (Gustavo)
Limit WA only for PTL platform with a TODO note (Gustavo)
Add TCSS_DISP_MAILBOX_IN_CMD_RUN_BUSY for clarity when writing
register data (Gustavo)
Move register defs from i915_reg.h to intel_cx0_phy_regs.h (Gustavo)

The IRQ indexes for the intf_6 underrun/vsync interrupts are swapped.
DPU_IRQ_IDX(MDP_SSPP_TOP0_INTR, 16) is the actual underrun interrupt and
DPU_IRQ_IDX(MDP_SSPP_TOP0_INTR, 17) is the vsync interrupt.
This causes timeout errors when using the DP2 controller, e.g.
[dpu error]enc37 frame done timeout
*ERROR* irq timeout id=37, intf_mode=INTF_MODE_VIDEO intf=6 wb=-1, pp=2, intr=0
*ERROR* wait disable failed: id:37 intf:6 ret:-110
Correct them to fix these errors and make DP2 work properly.
