ACPI 5 introduced two new resources to describe GPIO connections: GpioIo
and GpioInt. These resources are used be used to pass GPIO numbers used by

the device to the driver. ACPI 5.1 extended this with _DSD (Device

With the release of ACPI 5.1, the _DSD configuration object finally
allows names to be given to GPIOs (and other things as well) returned

the corresponding GPIO, which is pretty error prone (it depends on
the _CRS output ordering, for example).

@ -74,23 +74,22 @@ Causes of transaction aborts
Syscalls
========
Syscalls made from within an active transaction will not be performed and the
transaction will be doomed by the kernel with the failure code TM_CAUSE_SYSCALL
| TM_CAUSE_PERSISTENT.
Performing syscalls from within transaction is not recommended, and can lead
to unpredictable results.
Syscalls made from within a suspended transaction are performed as normal and
the transaction is not explicitly doomed by the kernel. However, what the
kernel does to perform the syscall may result in the transaction being doomed
by the hardware. The syscall is performed in suspended mode so any side
effects will be persistent, independent of transaction success or failure. No
guarantees are provided by the kernel about which syscalls will affect
transaction success.
Syscalls do not by design abort transactions, but beware: The kernel code will
not be running in transactional state. The effect of syscalls will always
remain visible, but depending on the call they may abort your transaction as a
side-effect, read soon-to-be-aborted transactional data that should not remain
invisible, etc. If you constantly retry a transaction that constantly aborts
itself by calling a syscall, you'll have a livelock & make no progress.
Care must be taken when relying on syscalls to abort during active transactions
if the calls are made via a library. Libraries may cache values (which may
give the appearance of success) or perform operations that cause transaction
failure before entering the kernel (which may produce different failure codes).
Examples are glibc's getpid() and lazy symbol resolution.
Simple syscalls (e.g. sigprocmask()) "could" be OK. Even things like write()
from, say, printf() should be OK as long as the kernel does not access any
memory that was accessed transactionally.
Consider any syscalls that happen to work as debug-only -- not recommended for
production use. Best to queue them up till after the transaction is over.
