then checking that against ULONG_MAX. Instead use a "unsigned long"
as the temporary variable. Then check against UINT32_MAX before
assigning back to the original variable.
There's no use assigning the output of strtoul() to a 32-bit variable
then checking that against ULONG_MAX. Instead use a "unsigned long"
as the temporary variable. Also, only check against UID_MAX/GID_MAX;
these are both going to be smaller than ULONG_MAX on both 32- and 64-bit
platforms.
* Garbage-collect some unused stuff.
* Make the Tx window slide along the Tx job queue space, not the
Tx descriptor space. We are more likely to run low on DMA maps
than we are hardware descriptors.
* When forcing an interrupt, make sure that interrupt-delay-enable is
cleared (necessary with last change to make sure it's set for all
descriptors).
* Crank up the Transmit Interrupt Delay Value to 1024 * 1.024 msec. We
really want these to be deferred.
not actually be able to unblock the interrupt, which would cause us
to run the softclock interrupts with hardclock blocked.
Per discussion w/ Charles Hannum.
- build (mdset/nm/strip) into ${filename} as one rule, and move ${filename}.gz
into separate rule
- rename MDSET.${filename}.nosymbols -> MDSET_NOSYMBOLS.${filename}
- rename MDSET.${filename}.post -> MDSET_POST.${filename}, and don't do
suffix handling here
- rework suffix handling:
- rename MDSET.${filename}.suffixes -> MDSET_SUFFIXES.${filename},
and change from list of suffixes to list of "suffix cmdtobuildsuffix",
where cmdtobuildsuffix is the name of the variable containing the
command to build ${filename}.${suffix} (available as "${.TARGET}").
- for each ${filename}.${suffix}, depend upon ${filename} and use
${cmdtobuildsuffix} to create the former.
- add separate ${filename}.${suffix}.gz rule
- mipsco & pmax: rename "install.gz" to "netbsd-INSTALL.gz", for
consistency and so the target to build the mdset kernel doesn't get
confused with general "install" target
context setup.
* Implement Matt Thomas's sliding Tx interrupt window algorithm,
forcing an interrupt when the Tx desc list is 2/3 consumed.
* Use the Report Packet Sent interrupt, rather than Report Status,
since we use the Tx descriptor to count Tx errors.
contigous anymore, we can't call vdevgone() for the whole range at once.
(we should probably change the vdevgone() interface)
This also fixes some wrong use of DISKUNIT().
switch back to MII mode. Keep a sliding window for TX segments and when it
gets > 2/3 full, request a TX interrupt (window gets reset when the h/w TX
queue is empty). Add dv_xname to a few printfs. With the above changes,
the gem driver will now work on Macintoshes, even in GigE mode. On a 733
PowerMac G4 it gets ~355Mb/s TX and ~280Mb/s RX to/from an Alpha XP1000.
XXX mii autoselect is still flakey.
