ahead and write behind, improving performance for the Universal
Software Radio Peripheral (USRP) used with GNU Radio.
Enable UGEN_BULK_RA_WB in GENERIC and GENERIC_LAPTOP; behavior is
unchanged unless the new ioctl is called.
This code was written by Joanne Mikkelson under funding from DARPA's
ACERT program.
ok'd by christos@, tested by Berndt Josef Wulf
commands to the controller.
Add a amrctl(8) control tool, which for now only allows to get status
from the adapter (status of adapter, logical volumes and and individual
drives).
From FreeBSD, with some adjustements by Andrew Doran and me.
Sam Leffler, used in various products including AR5312-based designs. This
is not enabled in any configs yet, nor tested by anyone other than Sam. I
will be testing this more later, and adding it to appropriate configs once
I have verified (unless someone else beats me to the punch.)
introduce fileassoc(9), a kernel interface for associating meta-data with
files using in-kernel memory. this is very similar to what we had in
veriexec till now, only abstracted so it can be used more easily by more
consumers.
this also prompted the redesign of the interface, making it work on vnodes
and mounts and not directly on devices and inodes. internally, we still
use file-id but that's gonna change soon... the interface will remain
consistent.
as a result, veriexec went under some heavy changes to conform to the new
interface. since we no longer use device numbers to identify file-systems,
the veriexec sysctl stuff changed too: kern.veriexec.count.dev_N is now
kern.veriexec.tableN.* where 'N' is NOT the device number but rather a
way to distinguish several mounts.
also worth noting is the plugging of unmount/delete operations
wrt/fileassoc and veriexec.
tons of input from yamt@, wrstuden@, martin@, and christos@.
with any actual 10-bit devices (as I don't have any), but it doesn't seem to
impact 7-bit addressing any. Approved by christos@, briggs@, and thorpej@.
in the bus layer and remove from common ath_attach().
Having it in both layers (on some bus architectures)
was causing a double call to ath_stop() on shutdown
which in turn was tickling the bus lockup described
therin on slower machines.
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.
Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.
This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.
Approved by core@. Fixes PR port-evbmips/32362.
