The timerlat tracer provides an interface for any application to wait
for the timerlat's periodic wakeup. Currently, rtla timerlat uses it
to dispatch its user-space workload (-u option).
But as the tracer interface is generic, rtla timerlat can also be used
to monitor any workload that uses it. For example, a user might
place their own workload to wait on the tracer interface, and
monitor the results with rtla timerlat.
Add the -U option to rtla timerlat top and hist. With this option, rtla
timerlat will not dispatch its workload but only setting up the
system, waiting for a user to dispatch its workload.
The sample code in this patch is an example of python application
that loops in the timerlat tracer fd.
To use it, dispatch:
# rtla timerlat -U
In a terminal, then run the python program on another terminal,
specifying the CPU to run it. For example, setting on CPU 1:
#./timerlat_load.py 1
Then rtla timerlat will start printing the statistics of the
./timerlat_load.py app.
An interesting point is that the "Ret user Timer Latency" value
is the overall response time of the load. The sample load does
a memory copy to exemplify that.
The stop tracing options on rtla timerlat works in this setup
as well, including auto analysis.

Use tools/build/ makefiles to build rtla, inheriting the benefits of
it. For example, having a proper way to handle dependencies.
rtla is built using perf infra-structure when building inside the
kernel tree.
At this point, rtla diverges from perf in two points: Documentation
and tarball generation/build.
At the documentation level, rtla is one step ahead, placing the
documentation at Documentation/tools/rtla/, using the same build
tools as kernel documentation. The idea is to move perf
documentation to the same scheme and then share the same makefiles.
rtla has a tarball target that the (old) RHEL8 uses. The tarball was
kept using a simple standalone makefile for compatibility. The
standalone makefile shares most of the code, e.g., flags, with
regular buildings.
The tarball method was set as deprecated. If necessary, we can make
a rtla tarball like perf, which includes the entire tools/build.
But this would also require changes in the user side (the directory
structure changes, and probably the deps to build the package).
Inspired on perf and objtool.

for a deadlock in recovery when we have to rewrite large numbers of

This was visible to users as "bch2_btree_update_start(): error:

These are changes that for some reason ended up not making it into the
first four branches but that should still make it into 6.9:
- A rework of the omap clock support that touches both drivers and
device tree files
- The reset controller branch changes that had a dependency on late
bugfixes. Merging them here avoids a backmerge of 6.8-rc5 into the
drivers branch
- The RISC-V/starfive, RISC-V/microchip and ARM/Broadcom devicetree
changes that got delayed and needed some extra time in linux-next
for wider testing.

Pull more ARM SoC updates from Arnd Bergmann:
"These are changes that for some reason ended up not making it into the
first four branches but that should still make it into 6.9:
- A rework of the omap clock support that touches both drivers and
device tree files
- The reset controller branch changes that had a dependency on late
bugfixes. Merging them here avoids a backmerge of 6.8-rc5 into the
drivers branch
- The RISC-V/starfive, RISC-V/microchip and ARM/Broadcom devicetree
changes that got delayed and needed some extra time in linux-next
for wider testing"

- Various virtual vs physical address usage fixes
- Add new bitwise types and helper functions and use them in s390 specific
drivers and code to make it easier to find virtual vs physical address
usage bugs. Right now virtual and physical addresses are identical for
s390, except for module, vmalloc, and similar areas. This will be
changed, hopefully with the next merge window, so that e.g. the kernel
image and modules will be located close to each other, allowing for
direct branches and also for some other simplifications.
As a prerequisite this requires to fix all misuses of virtual and
physical addresses. As it turned out people are so used to the concept
that virtual and physical addresses are the same, that new bugs got added
to code which was already fixed. In order to avoid that even more code
gets merged which adds such bugs add and use new bitwise types, so that
sparse can be used to find such usage bugs.
Most likely the new types can go away again after some time
- Provide a simple ARCH_HAS_DEBUG_VIRTUAL implementation
- Fix kprobe branch handling: if an out-of-line single stepped relative
branch instruction has a target address within a certain address area in
the entry code, the program check handler may incorrectly execute cleanup
code as if KVM code was executed, leading to crashes
- Fix reference counting of zcrypt card objects
- Various other small fixes and cleanups

As __assign_str() no longer uses its "src" parameter, there's a check to
make sure nothing depends on it being different than what was passed to
__string(). It originally just compared the pointer passed to __string()
with the pointer passed into __assign_str() via the "src" parameter. But
there's a couple of outliers that just pass in a quoted string constant,
where comparing the pointers is UB to the compiler, as the compiler is
free to create multiple copies of the same string constant.
Instead, just use strcmp(). It may slow down the trace event, but this
will eventually be removed.
Also, fix the issue of passing NULL to strcmp() by adding a WARN_ON() to
make sure that both "src" and the pointer saved in __string() are either
both NULL or have content, and then checking if "src" is not NULL before
performing the strcmp().

Likewise, they do not allow you to probe the devices behind an
attached PMP, as defined according to the SATA-IO PMP specification.
Instead, they have decided to implement their own version of PMP,
and because of this, plugging in a PMP actually works, even if the
HBA claims that it does not support PMP.
Revert a recent quirk for these HBAs, as that breaks ASMedia's own

Unfortunately, this will once again give some users of these HBAs
significantly increased boot time. However, a longer boot time for
some, is the lesser evil compared to some other users not being able
to detect their drives at all.

When sync or dir_sync is enabled, there is no need to sync the
parent directory's inode if only for updating its timestamp.
1. If an unexpected power failure occurs, the timestamp of the
parent directory is not updated to the storage, which has no
impact on the user.
2. The number of writes will be greatly reduced, which can not
only improve performance, but also prolong device life.

Before this conversion, each dentry traversed needs to be read
from the storage device or page cache. There are at least 16
dentries in a sector. This will result in frequent page cache

exfat_init_ext_entry() is an init function, it's a bit strange
to free cluster in it. And the argument 'inode' will be removed
from exfat_init_ext_entry(). So this commit changes to free the

Previously, patches have been added to limit the reported count of SATA
ports for asm1064 and asm1166 SATA controllers, as those controllers do
report more ports than physically having.
While it is allowed to report more ports than physically having in CAP.NP,
it is not allowed to report more ports than physically having in the PI
(Ports Implemented) register, which is what these HBAs do.
(This is a AHCI spec violation.)
Unfortunately, it seems that the PMP implementation in these ASMedia HBAs
is also violating the AHCI and SATA-IO PMP specification.
What these HBAs do is that they do not report that they support PMP
(CAP.SPM (Supports Port Multiplier) is not set).
Instead, they have decided to add extra "virtual" ports in the PI register
that is used if a port multiplier is connected to any of the physical
ports of the HBA.
Enumerating the devices behind the PMP as specified in the AHCI and
SATA-IO specifications, by using PMP READ and PMP WRITE commands to the
physical ports of the HBA is not possible, you have to use the "virtual"
ports.
This is of course bad, because this gives us no way to detect the device
and vendor ID of the PMP actually connected to the HBA, which means that
we can not apply the proper PMP quirks for the PMP that is connected to
the HBA.
Limiting the port map will thus stop these controllers from working with
SATA Port Multipliers.
This patch reverts both patches for asm1064 and asm1166, so old behavior
is restored and SATA PMP will work again, but it will also reintroduce the
(minutes long) extra boot time for the ASMedia controllers that do not
have a PMP connected (either on the PCIe card itself, or an external PMP).
However, a longer boot time for some, is the lesser evil compared to some
other users not being able to detect their drives at all.

When use_dma_api and premapped are true, then the do_unmap is false.
Because the do_unmap is false, vring_unmap_extra_packed is not called by
detach_buf_packed.
if (unlikely(vq->do_unmap)) {
curr = id;
for (i = 0; i < state->num; i++) {
vring_unmap_extra_packed(vq,
&vq->packed.desc_extra[curr]);
curr = vq->packed.desc_extra[curr].next;
}
}
So the indirect desc table is not unmapped. This causes the unmap leak.
So here, we check vq->use_dma_api instead. Synchronously, dma info is
updated based on use_dma_api judgment
This bug does not occur, because no driver use the premapped with
indirect.
