[ Upstream commit dbf797655a43c6318ebb90b899e6583fcadc6472 ]
issue:
sometime GFX/MM ib test hit timeout under SRIOV env, root cause
is that engine doesn't come back soon enough so the current
IB test considered as timed out.
fix:
for SRIOV GFX IB test wait time need to be expanded a lot during
SRIOV runtimei mode since it couldn't really begin before GFX engine
come back.
for SRIOV MM IB test it always need more time since MM scheduling
is not go together with GFX engine, it is controled by h/w MM
scheduler so no matter runtime or exclusive mode MM IB test
always need more time.
v2:
use ring type instead of idx to judge

[ Upstream commit 215003b4ae1d47035092fef73b6a22aa82037091 ]
There's no reason to delay initialization of most of the driver (such as
mapping memory I/O, getting clocks or enabling runtime PM) to the
component master bind handler.
This additionally fixes a real PM issue caused enabling runtime PM in
the bind handler.
The bind handler performs the following sequence of PM operations:
pm_runtime_enable(dev);
pm_runtime_get_sync(dev);
... (access the hardware to read the device revision) ...
pm_runtime_put_sync(dev);
If a failure occurs at this point, the error path calls
pm_runtime_disable() to balance the pm_runtime_enable() call.
To understand the problem, it should be noted that the bind handler is
called when one of the component registers itself, which happens in the
component's probe handler. Furthermore, as the components are children
of the DSS, the device core calls pm_runtime_get_sync() on the DSS
platform device before calling the component's probe handler. This
increases the DSS power usage count but doesn't runtime resume the
device, as runtime PM is disabled at that point.
The bind handler is thus called with runtime PM disabled, with the
device runtime suspended, but with the power usage count larger than 0.
The pm_runtime_get_sync() call will thus further increase the power
usage count and runtime resume the device. The pm_runtime_put_sync()
handler will decrease the power usage count to a non-zero value and will
thus not suspend the device. Finally, the pm_runtime_disable() call will
disable runtime PM, preventing the pm_runtime_put() call in the device
core from runtime suspending the device. The DSS device is thus left
powered on.
To fix this, move the initialization code from the bind handler to the
probe handler.

When dt_to_map_one_config() is called with a pinctrl_dev passed
in, it should only be using this if the node being looked up
is a hog. The code was always using the passed pinctrl_dev
without checking whether the dt node referred to it.
A pin controller can have pinctrl-n dependencies on other pin
controllers in these cases:
- the pin controller hardware is external, for example I2C, so
needs other pin controller(s) to be setup to communicate with
the hardware device.
- it is a child of a composite MFD so its of_node is shared with
the parent MFD and other children of that MFD. Any part of that
MFD could have dependencies on other pin controllers.
Because of this, dt_to_map_one_config() can't assume that if it
has a pinctrl_dev passed in then the node it looks up must be
a hog. It could be a reference to some other pin controller.

This patch fixes an issue that a race condition happens between a client
driver and the rcar-dmac driver:
- The rcar_dmac_isr_transfer_end() is called.
- The done list appears, and desc.running is the next active list.
- rcar_dmac_chan_get_residue() is called by a client driver before
rcar_dmac_isr_channel_thread() is called.
- The rcar_dmac_chan_get_residue() will not find any descriptors.
- And, the following WARNING happens:
WARN(1, "No descriptor for cookie!");
The sh-sci driver with HSCIF (921,600bps) on R-Car H3 can cause this
situation.
So, this patch checks the done lists in rcar_dmac_chan_get_residue()
and returns zero if the done lists has the argument cookie.

i2c i2c-0: sendbytes: NAK bailout.
Then no picture. Apparently the I2C engine inside the SiI9022
is not smart enough to try to fall back to DDC I2C. Or the
vendor have not integrated the electronics properly. I don't
know which one it is.
After this, the I2C bus seems stalled and the first attempt to
read the status register fails, and the code returns with
negative return value, and the display fails to initialized.
Instead, retry status readout five times and continue even
if this fails.
Tested on the ARM Versatile Express with a DVI-to-VGA
connector, it now gives picture.

In gfs2_quota_lock_check, always set ap->allowed to UINT_MAX to indicate
that there is no quota limit. This fixes callers that rely on
ap->allowed to be set even when quotas are off.

There is a bug when reading event->count with large PEBS enabled.
Here is an example:
# ./read_count
0x71f0
0x122c0
0x1000000001c54
0x100000001257d
0x200000000bdc5
In fixed period mode, the auto-reload mechanism could be enabled for
PEBS events, but the calculation of event->count does not take the
auto-reload values into account.
Anyone who reads event->count will get the wrong result, e.g x86_pmu_read().
This bug was introduced with the auto-reload mechanism enabled since
commit:
851559e35fd5 ("perf/x86/intel: Use the PEBS auto reload mechanism when possible")
Introduce intel_pmu_save_and_restart_reload() to calculate the
event->count only for auto-reload.
Since the counter increments a negative counter value and overflows on
the sign switch, giving the interval:
[-period, 0]
the difference between two consequtive reads is:
A) value2 - value1;
when no overflows have happened in between,
B) (0 - value1) + (value2 - (-period));
when one overflow happened in between,
C) (0 - value1) + (n - 1) * (period) + (value2 - (-period));
when @n overflows happened in between.
Here A) is the obvious difference, B) is the extension to the discrete
interval, where the first term is to the top of the interval and the
second term is from the bottom of the next interval and C) the extension
to multiple intervals, where the middle term is the whole intervals
covered.
The equation for all cases is:
value2 - value1 + n * period
Previously the event->count is updated right before the sample output.
But for case A, there is no PEBS record ready. It needs to be specially
handled.
Remove the auto-reload code from x86_perf_event_set_period() since
we'll not longer call that function in this case.

Large fixed period values could be truncated on Broadwell, for example:
perf record -e cycles -c 10000000000
Here the fixed period is 0x2540BE400, but the period which finally applied is
0x540BE400 - which is wrong.
The reason is that x86_pmu::limit_period() uses an u32 parameter, so the
high 32 bits of 'period' get truncated.
This bug was introduced in:
commit 294fe0f52a44 ("perf/x86/intel: Add INST_RETIRED.ALL workarounds")
It's safe to use u64 instead of u32:
- Although the 'left' is s64, the value of 'left' must be positive when
calling limit_period().
- bdw_limit_period() only modifies the lowest 6 bits, it doesn't touch
the higher 32 bits.

This task tried to open the cdrom device, the sr_block_open function
acquired the global sr_mutex lock. The call to check_disk_change()
then saw an event flag indicating a possible media change and tried
to flush any cached data for the device.
As part of the flush, it tried to acquire the super_block->s_umount
lock associated with the cdrom device.
This was the same super_block as created and locked by the previous task.
The first task acquires the s_umount lock and then the sr_mutex_lock;
the second task acquires the sr_mutex_lock and then the s_umount lock.
This patch fixes the issue by moving check_disk_change() out of
cdrom_open() and let the caller take care of it.

do_signal+0x144/0x4f8
do_notify_resume+0x148/0x1e8
work_pending+0x8/0x14
which asserts that we only call pmu::read() on ACTIVE events.
The above callchain does:
perf_event_exit_task()
perf_event_exit_task_context()
task_ctx_sched_out() // INACTIVE
perf_event_exit_event()
perf_event_set_state(EXIT) // EXIT
sync_child_event()
perf_event_read_event()
perf_output_read()
perf_output_read_group()
leader->pmu->read()
Which results in doing a pmu::read() on an !ACTIVE event.
I _think_ this is 'new' since we added attr.inherit_stat, which added
the perf_event_read_event() to the exit path, without that
perf_event_read_output() would only trigger from samples and for
@event to trigger a sample, it's leader _must_ be ACTIVE too.
Still, adding this check makes it consistent with the @sub case for
the siblings.

There's two problems when installing cgroup events on CPUs: firstly
list_update_cgroup_event() only tries to set cpuctx->cgrp for the
first event, if that mismatches on @cgrp we'll not try again for later
additions.
Secondly, when we install a cgroup event into an active context, only
issue an event reprogram when the event matches the current cgroup
context. This avoids a pointless event reprogramming.

As Jayashree Mohan reported:
A simple workload to reproduce this would be :
1. create foo
2. Write (8K - 16K) // foo size = 16K now
3. fsync()
4. falloc zero_range , keep_size (4202496 - 4210688) // foo size must be 16K
5. fdatasync()
Crash now
On recovery, we see that the file size is 4210688 and not 16K, which
violates the semantics of keep_size flag. We have a test case to
reproduce this using CrashMonkey on 4.15 kernel. Try this out by
simply running :
./c_harness -f /dev/sda -d /dev/cow_ram0 -t f2fs -e 102400 -P -v
tests/generic_468_zero.so
The root cause is that we miss to set KEEP_SIZE bit correctly in zero_range
when zeroing block cross EOF with FALLOC_FL_KEEP_SIZE, let's fix this
missing case.

PSL9D doesn't have a data-cache that needs to be flushed before
resetting the card. However when cxl tries to flush data-cache on such
a card, it times-out as PSL_Control register never indicates flush
operation complete due to missing data-cache. This is usually
indicated in the kernel logs with this message:
"WARNING: cache flush timed out"
To fix this the patch checks PSL_Debug register CDC-Field(BIT:27)
which indicates the absence of a data-cache and sets a flag
'no_data_cache' in 'struct cxl_native' to indicate this. When
cxl_data_cache_flush() is called it checks the flag and if set bails
out early without requesting a data-cache flush operation to the PSL.

[ Upstream commit 2b74e2a9b39df40a2b489af2d24079617c61ee0e ]
When sending TLB invalidates to the NPU we need to send extra flushes due
to a hardware issue. The original implementation would lock the all the
ATSD MMIO registers sequentially before unlocking and relocking each of
them sequentially to do the extra flush.
This introduced a deadlock as it is possible for one thread to hold one
ATSD register whilst waiting for another register to be freed while the
other thread is holding that register waiting for the one in the first
thread to be freed.
For example if there are two threads and two ATSD registers:
Thread A Thread B
----------------------
Acquire 1
Acquire 2
Release 1 Acquire 1
Wait 1 Wait 2
Both threads will be stuck waiting to acquire a register resulting in an
RCU stall warning or soft lockup.
This patch solves the deadlock by refactoring the code to ensure registers
are not released between flushes and to ensure all registers are either
acquired or released together and in order.

RK3399 has rst_pulse_length in CONTROL_REG[4:2], determining the length
of pulse to issue for system reset. We shouldn't clobber this value,
because that might make the system reset ineffective. On RK3399, we're
seeing that a value of 000b (meaning 2 cycles) yields an unreliable
(partial?) reset, and so we only fully reset after the watchdog fires a
second time. If we retain the system default (010b, or 8 clock cycles),
then the watchdog reset is much more reliable.
Read-modify-write retains the system value and improves reset
reliability.
It seems we were intentionally clobbering the response mode previously,
to ensure we performed a system reset (we don't support an interrupt
notification), so retain that explicitly.

We leave PCI devices not bound to a driver in D0 during runtime suspend.
But they may have a parent which is bound and can be transitioned to
D3cold at runtime. Once the parent goes to D3cold, the unbound child
may go to D3cold as well. When the child goes to D3cold, its internal
state, including configuration of BARs, MSI, ASPM, MPS, etc., is lost.
One example are recent hybrid graphics laptops which cut power to the
discrete GPU when the root port above it goes to ACPI power state D3.
Users may provoke this by unbinding the GPU driver and allowing runtime
PM on the GPU via sysfs: The PM core will then treat the GPU as
"suspended", which in turn allows the root port to runtime suspend,
causing the power resources listed in its _PR3 object to be powered off.
The GPU's BARs will be uninitialized when a driver later probes it.
Another example are hybrid graphics laptops where the GPU itself (rather
than the root port) is capable of runtime suspending to D3cold. If the
GPU's integrated HDA controller is not bound and the GPU's driver
decides to runtime suspend to D3cold, the HDA controller's BARs will be
uninitialized when a driver later probes it.
Fix by saving and restoring config space over a runtime suspend cycle
even if the device is not bound.

[ Upstream commit 05454c1bde91fb013c0431801001da82947e6b5a ]
According to the QCA u-boot source the "PCIE Phase Lock Loop
Configuration (PCIE_PLL_CONFIG)" register is for all SoCs except the
QCA955X and QCA956X at offset 0x10.
Since the PCIE PLL config register is only defined for the AR724x fix
only this value. The value is wrong since the day it was added and isn't
used by any driver yet.

For some reason, commit c0368e4db4a3 ("spi: bcm-qspi: Fix use after free
in bcm_qspi_probe() in error path") has updated some gotos, but not all of
them.
This looks spurious, so fix it.
