Some filesystems do not provide inode numbers through readdir (FUSE mounts
without -o use_ino). We therefore have to lookup each directory entry to
get the missing numbers.
dot and double-dot are exceptions, as we already know the values. Moreover,
the lookup code does not expect to get requests for dot and will abort
perfused(8) when it gets some. In order to fix that, we just check for
dot and double-dot special case and use the known values instead of sending
a lookup.
this driver controls CESA unit as same as mvcesa, but uses DMA engines and
does CBC operations, HMAC operations by hardware. about 2 kbytes of data
are processed at one. supported algorithms are:
- DES-CBC, 3DES-CBC, AES-CBC
- HMAC-SHA1, HMAC-MD5
non-CBC algorithm such as AES-GCM is not supported by CESA's acceleration
engine. mvcesa is still useful to implement such algorithms as combination of
accelerated block cipher and software chaining.
the buffer management(ex. fill the rx descriptors/buffers) is done by H/W in
ARMADA XP/380, and is done by S/W in ARMADA 370. the H/W BM support is not yet
implemented, so all devices use the S/W management mode at this time.
some versions of u-boot initializes the address decoder incorrectly(probably
these values are come from Kirkwood SoC or older.) the codes generates
SoC's default address spaces and some modifications for NetBSD's assumption.
add error interrupt definitions, interrupt name strings for 'vmstat -e',
verbose output of Mbus settings for such low-level debugging of SoC.
- Add SERDES specific functions.
- Fix IO pin configuration.
- Reset autonego timer when link becomes up.
TODO:
- Fix a bug that SFP ROM can't read.
- Perhaps some work is required for 8257[12] serdes systems.
- Remove duplicated code in TBI's link related functions.
of cv_timedwait() on the pagedaemon condvar -- it's no use constantly
waking the pagedaemon up for new memory allocation attempts, as will
happen e.g. if new network connections are constantly pouring in.
