used in the event that we can't malloc a buffer of the appropriate
size in the traditional way. rf_AllocIOBuffer() and rf_FreeIOBuffer()
deal with allocating/freeing these structures. These buffers are
stored in a list on the 'iobuf' list. iobuf_count keeps track of how
many buffers are available, and numEmergencyBuffers is the effective
"high-water" mark for the freelist. The buffers allocated by
rf_AllocIOBuffer() are stripe-unit sized, which is the maximum
size requested by any of the callers.
Add an iobufs entry to RF_DagHeader_s. Use it for keeping track of
buffers that get allocated from the free-list.
Add a "generic list" pool (VoidPointerListElement Pool) for elements
used to maintain a list of allocated memory. [It is somewhat less
than ideal to add another little pool to handle this...]
Teach rf_AllocBuffer() to use the new rf_AllocIOBuffer(). Modify
other Mallocs to use rf_AllocIOBuffer(), and to update dag_h->iobufs as
appropriate.
Update rf_FreeDAG() to handle cleanup of dag_h->iobufs.
While here, add some missing pool_destroy() calls for a number of pools.
With these changes, it should (in theory) be possible to swap on
RAID 5 sets again. That said, I've not had any success there yet --
but the last issue I saw at least wasn't in RAIDframe. :-}
[There is room for this code to become a bit more consise, but I
wanted to do a checkpoint here with something known to work :) ]
Add 'XXX FIXME' comments to ah4_ctlinput(), esp4_ctlinput()
ipcode-paths merely cast away local variables ip, ah/esp, sav; the
fast-ipsec IPv4 code appears to work even so.
In espv6_ctlinput(), call the fast-ipsec KEY_ALLOCSA()/KEY_FREESA()
macros, not the KAME-native key_allocsa()/key_freesa() functions.
Cast sa6_src/sa6_dst to void; the fast-ipsec API does not (yet) pass
both src and dst addrs to KEY_d-ALLOCSA/KEY_FREESA.
Make sure 'off' is set to 0 on the branch where it was formerly
used-before-set.
Will now compile with ``options INET6'' (as in
sys/arch/i386/conf/GENERIC.FAST_IPSEC), but is not yet
expected to acutally work with IPv6.
Rx interrupts, functions to post a request for new table entries, and
code to apply pending Rx-interrupt control values at the next hardware
interrupt.
As used in a third-party proprietary tree since at least March 2003.
As discussed on tech-kern/tech-net in January 2004 (in the context of
NetBSD for packet capture, bpf, and FreeBSD-sylte IFF_POLL), and as
posted to tech-net for comments in mid-March 2004.
Still missing sysctl or other knobs to acutally change the config-time
values, due to my ignorance of any accepted per-device sysctl namespace.
(e.g., polling for a half-second or more at splnet(), blocking most
interrupts, durin an ifconfig down/ifconfig up).
Appears to help for a 5704C rev A3, which is the only chip I've
ever seen that had even a mild version of the reported problem.
get properly probed and initialized. This also fixes the problem of the
keyboard getting the console output and the keyboard port getting the wrong
serial baud rate. The lcg driver is not currently present, but should be
"real soon now".
already mapped in the early console startup.
The software cursor isn't going to blink if we don't start it - set up the
callout when attaching.
Now that the cursor blink routine is actually called, blink the entire cursor
line rather than just the first pixel.
Don't try to clear the current cursor if the pointer to it hasn't been
initialized. This seems to happen when using the display as console, but
not when using a serial console.
On early console startup, use the framebuffer sizes, not the character cell
size to compute how much to clear.
The lcspx display will now initialize when booting with the display console,
but the dz device is not detected and the keyboard will not work yet. I
haven't tracked down why the dz device isn't found (it works fine when
using a serial console).
indicates that the target of the fdisk operation is a file, not a
disk. With -t and -T, the user tells fdisk the geometry for the
file If the default geometry that fdisk will "fake up" for a file
are not satisfactory, the user may tell the geometry to fdisk using
-t disktab -T disktype.
for RF_DagNode_t's. Scale the structure size based on RF_MAXCOL.
Use the new allocation method in InitNode(). Note that we can't get
rid of the mallocs in there until we can prove that this new
allocation method is a strict upper bound. Unless someone tries
running a RAID set with 40 components, the mallocs here shouldn't
shouldn't be an issue. (and if someone does make a set with 40 components
they will run into other issues with other constants long before
then)
- Pull rf_FreePhysDiskAddr() out from under a #ifdef, since we're now
going to use it.
- Add a pda_cleanup_list into the DAG header. Use it in rf_FreeDAG() to
cleanup any PDA's that get allocated but have no "easy" way of being
located and freed when the DAG completes.
- numStripeUnitsAccessed is a per-stripe value, and has a maximum
value equal to the number of colums (thus limited by RF_MAXCOL).
Use this knowledge to set a high-bound on overlappingPDAs, and stuff
it on the stack instead of malloc'ing it all the time! This costs us
a whopping 40 bytes on the stack, but saves a malloc() and a free().
