The Arm SP810 IP is a "system controller", providing clocks, timer and a
watchdog.
Convert the DT binding to DT schema, to allow automatic validation.
The existing .txt binding described all properties as required, but the
assigned-clock* and clock-output-names are actually not (from a hardware
perspective). The only existing driver I could find (in Linux) doesn't
require them either, so drop those properties from the "required" list.

The Page Request Interface (PRI) is an optional PCIe feature. As such, a
SMMU would not need to handle it if the PCIe host bridge or the SMMU
itself do not implement it. Also an SMMU could be connected to a platform
device, without any PRI functionality whatsoever.
In all cases there would be no SMMU PRI queue interrupt to be wired up
to an interrupt controller.
At the moment, with the "eventq,gerror,priq,cmdq-sync" order, we
would need to sacrifice the command queue sync interrupt as well, which
might not be desired.
Relax the binding to allow specifying certain useful combinations of
wired interrupts, for instance just the "gerror" interrupt, or omitting
both "pri" and "cmdq-sync".

Kernel imposes a pretty particular restriction on ringbuf map size. It
has to be a power-of-2 multiple of page size. While generally this isn't
hard for user to satisfy, sometimes it's impossible to do this
declaratively in BPF source code or just plain inconvenient to do at
runtime.
One such example might be BPF libraries that are supposed to work on
different architectures, which might not agree on what the common page
size is.
Let libbpf find the right size for user instead, if it turns out to not
satisfy kernel requirements. If user didn't set size at all, that's most
probably a mistake so don't upsize such zero size to one full page,
though. Also we need to be careful about not overflowing __u32
max_entries.

end users. While a bit advanced and specialized instruments, they are
sometimes indispensable. Instead of requiring each user to figure out
exact asm volatile incantations for themselves, provide them from

Also remove conflicting definitions from selftests. Some tests rely on
barrier_var() definition being nothing, those will still work as libbpf
does the #ifndef/#endif guarding for barrier() and barrier_var(),

Allow to specify field reference in two ways:
- if user has variable of necessary type, they can use variable-based
reference (my_var.my_field or my_var_ptr->my_field). This was the
only supported syntax up till now.
- now, bpf_core_field_exists() and bpf_core_field_size() support also
specifying field in a fashion similar to offsetof() macro, by
specifying type of the containing struct/union separately and field
name separately: bpf_core_field_exists(struct my_type, my_field).

The panic notifier infrastructure executes registered callbacks when
a panic event happens - such callbacks are executed in atomic context,
with interrupts and preemption disabled in the running CPU and all other
CPUs disabled. That said, mutexes in such context are not a good idea.
This patch replaces a regular mutex with a mutex_trylock safer approach;
given the nature of the mutex used in the driver, it should be pretty
uncommon being unable to acquire such mutex in the panic path, hence
no functional change should be observed (and if it is, that would be
likely a deadlock with the regular mutex).

This patch uses __le16/__32 to define mailbox data structures. Then byte
order conversion are added for mailbox messages from VF to PF.

Currently, hns3 mailbox processing between PF and VF missed to convert
message byte order and use data type u16 instead of __le16 for mailbox
data process. These processes may cause problems between different
architectures.
So this patch uses __le16/__le32 data type to define mailbox data
structures. To be compatible with old hns3 driver, these structures use
one-byte alignment. Then byte order conversions are added to mailbox
messages from PF to VF.

Vector0 is used for common interrupt control events and is
irrelevant to performance. Currently, the driver sets the
default affinity of vector0 to NUMA nodes, which is unnecessary.
Therefore, the default setting is removed, and the driver does
not set the affinity for vector0.
