+ Add a quirk table.
+ Assume all else is a modern drive that can do variable block
lengths (this is the main reason for this work - the old driver
only ever seemed to write 512 byte blocks!).
+ Keep track of values for mtget's mt_fileno, mt_blkno.
+ Handle a few extra MTIOCTOP commands.
Ideas gleaned from our MI scsi tape driver and the FreeBSD CAM tape
driver. Tested on a TKZ09 (DEC badged Exabyte 8500), a TLZ06 (DEC
DAT) and TK50.
Many thanks to Pierre Bergdolt for helping with testing.
that is priority is rasied. Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.
This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).
XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX. This platforms still have this bug until their
XXX spl*() functions are fixed.
- 'struct fbsoftc' created, which points to a 'struct fbinfo'
- 'struct fbinfo' for each device is allocated with fballoc()
This means:
- Console device doesn't get different 'struct fbinfo' at attach
- Console device doesn't get initialized twice
- Color rcons now works
- The current Xserver MUST BE REBUILT.
- fix emitrules() like emitfiles() to deal with the prefix (otherwise it
would attempt to find the file in the normal base for the NORMAL_C rule).
- add emitincludes() which adds include directives for each prefix to the
$INCLUDES variable in the makefile.
- add %INCLUDES to each Makefile.arch to deal with the above.
this makes "prefix" actually work in a usable manner, and now i can move
on to fixing compiler warnings (errors) in the ESP code. :)
these and pass as the first parameter of ddb_init(). We used to pass
the contents of the start of the symbol table cast to an int, which for
an ELF kernel is "0x7f ELF" - not quite the symbol table size! How this
used to ever work I dunno...
