cpufreq/amd-pstate: Pass min/max_limit_perf as min/max_perf to amd_pstate_update
Currently, amd_pstate_update_freq passes the hardware perf limits as min/max_perf to amd_pstate_update, which eventually gets programmed into the min/max_perf fields of the CPPC_REQ register. Instead pass the effective perf limits i.e. min/max_limit_perf values to amd_pstate_update as min/max_perf.

cpufreq/amd-pstate: Modify the min_perf calculation in adjust_perf callback
Instead of setting a fixed floor at lowest_nonlinear_perf, use the min_limit_perf value, so that it gives the user the freedom to lower the floor further. There are two minimum frequency/perf limits that we need to consider in the adjust_perf callback. One provided by schedutil i.e. the sg_cpu->bw_min value passed in _min_perf arg, another is the effective value of min_freq_qos request that is updated in cpudata->min_limit_perf. Modify the code to use the bigger of these two values. Signed-off-by: Dhananjay Ugwekar <dhananjay.ugwekar@amd.com> Reviewed-by: Mario Limonciello <mario.limonciello@amd.com> Reviewed-by: Gautham R.

tracing fixes for v6.14:
Function graph accounting fixes:
- Fix the manage ops hashes
The function graph registers a "manager ops" and "sub-ops" to ftrace.
The manager ops does not have any callback but calls the sub-ops
callbacks. The manage ops hashes (what is used to tell ftrace what
functions to attach to) is built on the sub-ops it manages.
There was an error in the way it built the hash. An empty hash means to
attach to all functions. When the manager ops had one sub-ops it properly
copied its hash. But when the manager ops had more than one sub-ops, it
went into a loop to make a set of all functions it needed to add to the
hash. If any of the subops hashes was empty, that would mean to attach
to all functions. The error was that the first iteration of the loop
passed in an empty hash to start with in order to add the other hashes.
That starting hash was mistaken as to attach to all functions. This made
the manage ops attach to all functions whenever it had two or more
sub-ops, even if each sub-op was attached to only a single function.
- Do not add duplicate entries to the manager ops hash
If two or more subops hashes trace the same function, an entry for that
function will be added to the manager ops for each subops. This causes
waste and extra overhead.
Fprobe accounting fixes:
- Remove last function from fprobe hash
Fprobes has a ftrace hash to manage which functions an fprobe is attached
to. It also has a counter of how many fprobes are attached. When the last
fprobe is removed, it unregisters the fprobe from ftrace but does not
remove the functions the last fprobe was attached to from the hash. This
leaves the old functions attached. When a new fprobe is added, the fprobe
infrastructure attaches to not only the functions of the new fprobe, but
also to the functions of the last fprobe.
- Fix accounting of the fprobe counter
When a fprobe is added, it updates a counter. If the counter goes from
zero to one, it attaches its ops to ftrace. When an fprobe is removed, the
counter is decremented. If the counter goes from 1 to zero, it removes the
fprobes ops from ftrace. There was an issue where if two fprobes trace the
same function, the addition of each fprobe would increment the counter.
But when removing the first of the fprobes, it would notice that another
fprobe is still attached to one of its functions no it does not remove
the functions from the ftrace ops. But it also did not decrement the
counter. When the last fprobe is removed, the counter is still one. This
leaves the fprobes callback still registered with ftrace and it being
called by the functions defined by the fprobes ops hash. Worse yet,
because all the functions from the fprobe ops hash have been removed, that
tells ftrace that it wants to trace all functions. Thus, this puts the
state of the system where every function is calling the fprobe callback
handler (which does nothing as there are no registered fprobes), but this
causes a good 13% slow down of the entire system.
Other updates:
- Add a selftest to test the above issues to prevent regressions.
- Fix preempt count accounting in function tracing
Better recursion protection was added to function tracing which added
another layer of preempt disable. As the preempt_count gets traced in the
event, it needs to subtract the amount of preempt disabling the tracer
does to record what the preempt_count was when the trace was triggered.
- Fix memory leak in output of set_event
A variable is passed by the seq_file functions in the location that is
set by the return of the next() function. The start() function allocates
it and the stop() function frees it. But when the last item is found, the
next() returns NULL which leaks the data that was allocated in start().
The m->private is used for something else, so have next() free the data
when it returns NULL, as stop() will then just receive NULL in that case.

Pull tracing fixes from Steven Rostedt:
"Function graph accounting fixes:
- Fix the manage ops hashes
The function graph registers a "manager ops" and "sub-ops" to
ftrace. The manager ops does not have any callback but calls the
sub-ops callbacks. The manage ops hashes (what is used to tell
ftrace what functions to attach to) is built on the sub-ops it
manages.
There was an error in the way it built the hash. An empty hash
means to attach to all functions. When the manager ops had one
sub-ops it properly copied its hash. But when the manager ops had
more than one sub-ops, it went into a loop to make a set of all
functions it needed to add to the hash. If any of the subops hashes
was empty, that would mean to attach to all functions. The error
was that the first iteration of the loop passed in an empty hash to
start with in order to add the other hashes. That starting hash was
mistaken as to attach to all functions. This made the manage ops
attach to all functions whenever it had two or more sub-ops, even
if each sub-op was attached to only a single function.
- Do not add duplicate entries to the manager ops hash
If two or more subops hashes trace the same function, an entry for
that function will be added to the manager ops for each subops.
This causes waste and extra overhead.
Fprobe accounting fixes:
- Remove last function from fprobe hash
Fprobes has a ftrace hash to manage which functions an fprobe is
attached to. It also has a counter of how many fprobes are
attached. When the last fprobe is removed, it unregisters the
fprobe from ftrace but does not remove the functions the last
fprobe was attached to from the hash. This leaves the old functions
attached. When a new fprobe is added, the fprobe infrastructure
attaches to not only the functions of the new fprobe, but also to
the functions of the last fprobe.
- Fix accounting of the fprobe counter
When a fprobe is added, it updates a counter. If the counter goes
from zero to one, it attaches its ops to ftrace. When an fprobe is
removed, the counter is decremented. If the counter goes from 1 to
zero, it removes the fprobes ops from ftrace.
There was an issue where if two fprobes trace the same function,
the addition of each fprobe would increment the counter. But when
removing the first of the fprobes, it would notice that another
fprobe is still attached to one of its functions no it does not
remove the functions from the ftrace ops.
But it also did not decrement the counter, so when the last fprobe
is removed, the counter is still one. This leaves the fprobes
callback still registered with ftrace and it being called by the
functions defined by the fprobes ops hash. Worse yet, because all
the functions from the fprobe ops hash have been removed, that
tells ftrace that it wants to trace all functions.
Thus, this puts the state of the system where every function is
calling the fprobe callback handler (which does nothing as there
are no registered fprobes), but this causes a good 13% slow down of
the entire system.
Other updates:
- Add a selftest to test the above issues to prevent regressions.
- Fix preempt count accounting in function tracing
Better recursion protection was added to function tracing which
added another layer of preempt disable. As the preempt_count gets
traced in the event, it needs to subtract the amount of preempt
disabling the tracer does to record what the preempt_count was when
the trace was triggered.
- Fix memory leak in output of set_event
A variable is passed by the seq_file functions in the location that
is set by the return of the next() function. The start() function
allocates it and the stop() function frees it. But when the last
item is found, the next() returns NULL which leaks the data that
was allocated in start(). The m->private is used for something
else, so have next() free the data when it returns NULL, as stop()
will then just receive NULL in that case"

i2c: core: Allocate temporary client dynamically
drivers/i2c/i2c-core-base.c: In function ‘i2c_detect.isra’:
drivers/i2c/i2c-core-base.c:2544:1: warning: the frame size of 1312 bytes is larger than 1024 bytes [-Wframe-larger-than=]
2544 | }
| ^
Fix this by allocating the temporary client structure dynamically, as it
is a rather large structure (1216 bytes, depending on kernel config).
This is basically a revert of the to-be-fixed commit with some
checkpatch improvements.

The issue can be reproduced regardless of whether set_event is empty or

# cat /sys/kernel/tracing/set_event

The root cause is that s_next() returns NULL when nothing is found.
This results in s_stop() attempting to free a NULL pointer because its
parameter is NULL.
Fix the issue by freeing the memory appropriately when s_next() fails
to find anything.

ftrace: Correct preemption accounting for function tracing.
The function tracer should record the preemption level at the point when
the function is invoked. If the tracing subsystem decrement the
preemption counter it needs to correct this before feeding the data into
the trace buffer. This was broken in the commit cited below while
shifting the preempt-disabled section.
Use tracing_gen_ctx_dec() which properly subtracts one from the
preemption counter on a preemptible kernel.

selftests/ftrace: Update fprobe test to check enabled_functions file
A few bugs were found in the fprobe accounting logic along with it using the function graph infrastructure. Update the fprobe selftest to catch those bugs in case they or something similar shows up in the future. The test now checks the enabled_functions file which shows all the functions attached to ftrace or fgraph. When enabling a fprobe, make sure that its corresponding function is also added to that file. Also add two more fprobes to enable to make sure that the fprobe logic works properly with multiple probes.

fprobe: Fix accounting of when to unregister from function graph
When adding a new fprobe, it will update the function hash to the
functions the fprobe is attached to and register with function graph to
have it call the registered functions. The fprobe_graph_active variable
keeps track of the number of fprobes that are using function graph.
If two fprobes attach to the same function, it increments the
fprobe_graph_active for each of them. But when they are removed, the first
fprobe to be removed will see that the function it is attached to is also
used by another fprobe and it will not remove that function from
function_graph. The logic will skip decrementing the fprobe_graph_active
variable.
This causes the fprobe_graph_active variable to not go to zero when all
fprobes are removed, and in doing so it does not unregister from
function graph. As the fgraph ops hash will now be empty, and an empty
filter hash means all functions are enabled, this triggers function graph
to add a callback to the fprobe infrastructure for every function!

fprobe: Always unregister fgraph function from ops
When the last fprobe is removed, it calls unregister_ftrace_graph() to
remove the graph_ops from function graph. The issue is when it does so, it
calls return before removing the function from its graph ops via
ftrace_set_filter_ips(). This leaves the last function lingering in the
fprobe's fgraph ops and if a probe is added it also enables that last
function (even though the callback will just drop it, it does add unneeded
overhead to make that call).
# echo "f:myevent1 kernel_clone" >> /sys/kernel/tracing/dynamic_events
# cat /sys/kernel/tracing/enabled_functions
kernel_clone (1) tramp: 0xffffffffc02f3000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60
# echo "f:myevent2 schedule_timeout" >> /sys/kernel/tracing/dynamic_events
# cat /sys/kernel/tracing/enabled_functions
kernel_clone (1) tramp: 0xffffffffc02f3000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60

schedule_timeout (1) tramp: 0xffffffffc0219000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60
The above enabled a fprobe on kernel_clone, and then on schedule_timeout.
The content of the enabled_functions shows the functions that have a
callback attached to them. The fprobe attached to those functions
properly. Then the fprobes were cleared, and enabled_functions was empty
after that. But after adding a fprobe on kmem_cache_free, the
enabled_functions shows that the schedule_timeout was attached again. This
is because it was still left in the fprobe ops that is used to tell
function graph what functions it wants callbacks from.

ftrace: Fix accounting of adding subops to a manager ops
Function graph uses a subops and manager ops mechanism to attach to
ftrace. The manager ops connects to ftrace and the functions it connects
to is defined by a list of subops that it manages.
The function hash that defines what the above ops attaches to limits the
functions to attach if the hash has any content. If the hash is empty, it
means to trace all functions.
The creation of the manager ops hash is done by iterating over all the
subops hashes. If any of the subops hashes is empty, it means that the
manager ops hash must trace all functions as well.
The issue is in the creation of the manager ops. When a second subops is
attached, a new hash is created by starting it as NULL and adding the
subops one at a time. But the NULL ops is mistaken as an empty hash, and
once an empty hash is found, it stops the loop of subops and just enables
all functions.

Fix this by initializing the new hash to NULL and if the hash is NULL do
not treat it as an empty hash but instead allocate by copying the content
of the first sub ops. Then on subsequent iterations, the new hash will not
be NULL, but the content of the previous subops. If that first subops
attached to all functions, then new hash may assume that the manager ops
also needs to attach to all functions.

irqchip/qcom-pdc: Workaround hardware register bug on X1E80100
On X1E80100, there is a hardware bug in the register logic of the
IRQ_ENABLE_BANK register: While read accesses work on the normal address,
all write accesses must be made to a shifted address. Without a workaround
for this, the wrong interrupt gets enabled in the PDC and it is impossible
to wakeup from deep suspend (CX collapse). This has not caused problems so
far, because the deep suspend state was not enabled. A workaround is
required now since work is ongoing to fix this.
The PDC has multiple "DRV" regions, each one has a size of 0x10000 and
provides the same set of registers for a particular client in the system.
Linux is one the clients and uses DRV region 2 on X1E. Each "bank" inside
the DRV region consists of 32 interrupt pins that can be enabled using the
IRQ_ENABLE_BANK register:
IRQ_ENABLE_BANK[bank] = base + IRQ_ENABLE_BANK + bank * sizeof(u32)
On X1E, this works as intended for read access. However, write access to
most banks is shifted by 2:
IRQ_ENABLE_BANK_X1E[0] = IRQ_ENABLE_BANK[-2]
IRQ_ENABLE_BANK_X1E[1] = IRQ_ENABLE_BANK[-1]
IRQ_ENABLE_BANK_X1E[2] = IRQ_ENABLE_BANK[0] = IRQ_ENABLE_BANK[2 - 2]
IRQ_ENABLE_BANK_X1E[3] = IRQ_ENABLE_BANK[1] = IRQ_ENABLE_BANK[3 - 2]
IRQ_ENABLE_BANK_X1E[4] = IRQ_ENABLE_BANK[2] = IRQ_ENABLE_BANK[4 - 2]
IRQ_ENABLE_BANK_X1E[5] = IRQ_ENABLE_BANK[5] (this one works as intended)
The negative indexes underflow to banks of the previous DRV/client region:
IRQ_ENABLE_BANK_X1E[drv 2][bank 0] = IRQ_ENABLE_BANK[drv 2][bank -2]
= IRQ_ENABLE_BANK[drv 1][bank 5-2]
= IRQ_ENABLE_BANK[drv 1][bank 3]
= IRQ_ENABLE_BANK[drv 1][bank 0 + 3]
IRQ_ENABLE_BANK_X1E[drv 2][bank 1] = IRQ_ENABLE_BANK[drv 2][bank -1]
= IRQ_ENABLE_BANK[drv 1][bank 5-1]
= IRQ_ENABLE_BANK[drv 1][bank 4]
= IRQ_ENABLE_BANK[drv 1][bank 1 + 3]
Introduce a workaround for the bug by matching the qcom,x1e80100-pdc
compatible and apply the offsets as shown above:
- Bank 0...1: previous DRV region, bank += 3
- Bank 1...4: our DRV region, bank -= 2
- Bank 5: our DRV region, no fixup required
The PDC node in the device tree only describes the DRV region for the Linux
client, but the workaround also requires to map parts of the previous DRV
region to issue writes there. To maintain compatibility with old device
trees, obtain the base address of the preceeding region by applying the
-0x10000 offset. Note that this is also more correct from a conceptual
point of view:
It does not really make use of the other region; it just issues shifted
writes that end up in the registers of the Linux associated DRV region 2.

Fixes for v6.14-rc4 Display: * More catalog fixes: - to skip watchdog programming through top block if its not present - fix the setting of WB mask to ensure the WB input control is programmed correctly through ping-pong - drop lm_pair for sm6150 as that chipset does not have any 3dmerge block * Fix the mode validation logic for DP/eDP to account for widebus (2ppc) to allow high clock resolutions * Fix to disable dither during encoder disable as otherwise this was causing kms_writeback failure due to resource sharing between * WB and DSI paths as DSI uses dither but WB does not * Fixes for virtual planes, namely to drop extraneous return and fix uninitialized variables * Fix to avoid spill-over of DSC encoder block bits when programming the bits-per-component * Fixes in the DSI PHY to protect against concurrent access of PHY_CMN_CLK_CFG regs between clock and display drivers Core/GPU: * Fix non-blocking fence wait incorrectly rounding up to 1 jiffy timeout * Only print GMU fw version once, instead of each time the GPU resumes Signed-off-by: Dave Airlie <airlied@redhat.com> From: Rob Clark <robdclark@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/CAF6AEGtt2AODBXdod8ULXcAygf_qYvwRDVeUVtODx=2jErp6cA@mail.gmail.com |

nvme: only allow entering LIVE from CONNECTING state
The fabric transports and also the PCI transport are not entering the LIVE state from NEW or RESETTING. This makes the state machine more restrictive and allows to catch not supported state transitions, e.g. directly switching from RESETTING to LIVE.

nvme-fc: rely on state transitions to handle connectivity loss
It's not possible to call nvme_state_ctrl_state with holding a spin
lock, because nvme_state_ctrl_state calls cancel_delayed_work_sync
when fastfail is enabled.
Instead syncing the ASSOC_FLAG and state transitions using a lock, it's
possible to only rely on the state machine transitions. That means
nvme_fc_ctrl_connectivity_loss should unconditionally call
nvme_reset_ctrl which avoids the read race on the ctrl state variable.
Actually, it's not necessary to test in which state the ctrl is, the
reset work will only scheduled when the state machine is in LIVE state.
In nvme_fc_create_association, the LIVE state can only be entered if it
was previously CONNECTING. If this is not possible then the reset
handler got triggered. Thus just error out here.
