The current bandwidth calculation aggregates all the targets. This simple
method does not take into account where multiple targets sharing under
a switch or a root port where the aggregated bandwidth can be greater than
the upstream link of the switch.
To accurately account for the shared upstream uplink cases, a new update
function is introduced by walking from the leaves to the root of the
hierarchy and clamp the bandwidth in the process as needed. This process
is done when all the targets for a region are present but before the
final values are send to the HMAT handling code cached access_coordinate
targets.
The original perf calculation path was kept to calculate the latency
performance data that does not require the shared link consideration.
The shared upstream link calculation is done as a second pass when all
the endpoints have arrived.
Testing is done via qemu with CXL hierarchy. run_qemu[1] is modified to
support several CXL hierarchy layouts. The following layouts are tested:
HB: Host Bridge
RP: Root Port
SW: Switch
EP: End Point
2 HB 2 RP 2 EP: resulting bandwidth: 624
1 HB 2 RP 2 EP: resulting bandwidth: 624
2 HB 2 RP 2 SW 4 EP: resulting bandwidth: 624
Current testing, perf number from SRAT/HMAT is hacked into the kernel
code. However with new QEMU support of Generic Target Port that's
incoming, the perf data injection is no longer needed.

Keep the access_coordinate from the CDAT tables for region perf
calculations. The region perf calculation requires all participating
endpoints to have arrived in order to determine if there are limitations
of bandwidth data due to shared uplink.

Create a new 'struct cxl_mailbox' and move all mailbox related bits to
it. This allows isolation of all CXL mailbox data in order to export
some of the calls to external kernel callers and avoid exporting of CXL
driver specific bits such has device states. The allocation of
'struct cxl_mailbox' is also split out with cxl_mailbox_init() so the
mailbox can be created independently.

In testing Dynamic Capacity Device (DCD) support, a lockdep splat
revealed an ABBA issue between the memory notifiers and the DCD extent
processing code.[0] Changing the lock ordering within DCD proved
difficult because regions must be stable while searching for the proper
region and then the device lock must be held to properly notify the DAX
region driver of memory changes.
Dan points out in the thread that notifiers should be able to trust that
it is safe to access static data. Region data is static once the device
is realized and until it's destruction. Thus it is better to manage the
notifiers within the region driver.
Remove the need for a lock by ensuring the notifiers are active only
during the region's lifetime.
Furthermore, remove cxl_region_nid() because resource can't be NULL
while the region is stable.

Cases can be divided into two categories which are DVSEC range enabled and
not enabled when HDM decoders exist but is not enabled. To avoid checking
info->mem_enabled, which indicates the enablement of DVSEC range, every
time, we can check !info->mem_enabled once in advance. This simplification
can make the code clearer.
No functional change intended.

In theory a device might set the mem_info_valid bit for a first range
after it is ready but before as second range has reached that state.
Therefore, the correct approach is to check the Mem_info_valid bit for
each applicable DVSEC range against HDM_COUNT, rather than only for the
DVSEC range 1. Consequently, let's move the check into the "for loop"
that handles each DVSEC range.

commit ce17ad0d5498 ("cxl: Wait Memory_Info_Valid before access memory

cxl_dvsec_mem_range_valid(), of waiting for memory_info_valid without
realizing it duplicated wait_for_valid(). Remove wait_for_valid() and
retain cxl_dvsec_mem_range_valid() as the former is hardcoded to check
only the Memory_Info_Valid bit of DVSEC range 1, while the latter allows
for selection between DVSEC range 1 or 2 via parameter.

The function cxl_dvsec_rr_decode() retrieves and records DVSEC ranges
into info->dvsec_range[], regardless of whether it is non-zero range,
and the variable info->ranges indicates the number of non-zero ranges.
However, in cxl_hdm_decode_init(), the validation for
info->dvsec_range[] occurs in a for loop that iterates based on
info->ranges. It may result in zero range to be validated but non-zero
range not be validated, in turn, the number of allowed ranges is to be
0. Address it by only record non-zero ranges.
This fix is not urgent as it requires a configuration that zeroes out
the first dvsec range while populating the second. This has not been
observed, but it is theoretically possible. If this gets picked up for
-stable, no harm done, but there is no urgency to backport.

cxl_dport_map_ras() is used to map CXL RAS capability, the RCH AER
capability should not be mapped in the function but should mapped in
cxl_dport_init_ras_reporting(). Moving cxl_dport_map_ras() out of
cxl_dport_map_ras() and into cxl_dport_init_ras_reporting().
In cxl_dport_init_ras_reporting(), the AER capability position in RCRB
will be located but the position is only used in
cxl_dport_map_rch_aer(), getting the position in cxl_dport_map_rch_aer()
rather than cxl_dport_init_ras_reporting() is more reasonable and makes
the code clearer.
Besides, some local variables in cxl_dport_map_rch_aer() are
unnecessary, remove them to make the function more concise.

The name of cxl_setup_parent_dport() function is not clear, the function
is used to initialize AER and RAS capabilities on a dport, therefore,
rename the function to cxl_dport_init_ras_reporting(), it is easier for
user to understand what the function does. Besides, adjust the order of
the function parameters, the subject of cxl_dport_init_ras_reporting()
is a cxl dport, so a struct cxl_dport as the first parameter of the
function should be better.

In __devm_cxl_add_port(), there is a 'goto' to call put_device() for the
error cases between device_initialize() and device_add() to dereference
the 'struct device' of a new cxl_port. The 'goto' pattern in the case
can be removed by refactoring. Introducing a new function called
cxl_port_add() which is used to add the 'struct device' of a new
cxl_port to device hierarchy, moving the functions needing the help of
the 'goto' into cxl_port_add(), and using a scoped-based resource
management __free() to drop the open coded put_device() and the 'goto'
for the error cases.

We had a report of data corruption on nixos when building installer
images.
https://github.com/NixOS/nixpkgs/pull/321055#issuecomment-2184131334
It seems that writes are being dropped, but only when issued by QEMU,
and possibly only in snapshot mode. It's undetermined if it's write
calls are being dropped or dirty folios.
Further testing, via minimizing the original patch to just the change
that skips the inode lock on non appends/truncates, reveals that it
really is just not taking the inode lock that causes the corruption: it
has nothing to do with the other logic changes for preserving write
atomicity in corner cases.
It's also kernel config dependent: it doesn't reproduce with the minimal
kernel config that ktest uses, but it does reproduce with nixos's distro
config. Bisection the kernel config initially pointer the finger at page
migration or compaction, but it appears that was erroneous; we haven't
yet determined what kernel config option actually triggers it.
Sadly it appears this will have to be reverted since we're getting too
close to release and my plate is full, but we'd _really_ like to fully
debug it.
My suspicion is that this patch is exposing a preexisting bug - the
inode lock actually covers very little in IO paths, and we have a
different lock (the pagecache add lock) that guards against races with
truncate here.

io_provided_buffers_select() returns 0 to indicate success, but it should
be returning 1 to indicate that 1 vec was mapped. This causes peeking
to fail with classic provided buffers, and while that's not a use case
that anyone should use, it should still work correctly.
The end result is that no buffer will be selected, and hence a completion
with '0' as the result will be posted, without a buffer attached.

It is not safe to dereference fl->c.flc_owner without first confirming
fl->fl_lmops is the expected manager. nfsd4_deleg_getattr_conflict()
tests fl_lmops but largely ignores the result and assumes that flc_owner
is an nfs4_delegation anyway. This is wrong.
With this patch we restore the "!= &nfsd_lease_mng_ops" case to behave
as it did before the change mentioned below. This is the same as the
current code, but without any reference to a possible delegation.

For buffer registration (or updates), a userspace iovec is copied in
and updated. If the application is within a compat syscall, then the
iovec type is compat_iovec rather than iovec. However, the type used
in __io_sqe_buffers_update() and io_sqe_buffers_register() is always
struct iovec, and hence the source is incremented by the size of a
non-compat iovec in the loop. This misses every other iovec in the
source, and will run into garbage half way through the copies and
return -EFAULT to the application.
Maintain the source address separately and assign to our user vec
pointer, so that copies always happen from the right source address.
While in there, correct a bad placement of __user which triggered
the following sparse warning prior to this fix:
io_uring/rsrc.c:981:33: warning: cast removes address space '__user' of expression
io_uring/rsrc.c:981:30: warning: incorrect type in assignment (different address spaces)
io_uring/rsrc.c:981:30: expected struct iovec const [noderef] __user *uvec
io_uring/rsrc.c:981:30: got struct iovec *[noderef] __user
