specify device logical blocksize.
Furthermore, it also adds an 'immediate' option, which then sends more modern
devices into formatting in the background. scsictl still waits around and
sends a TEST UNIT READY every 10 seconds and, based upon the sense data
it gets back after the invariable CHECK CONDITION, prints out a progress
indicator (based upon SKSV progress in the sense data).
While we're at it, add a 'tur', 'reserve', 'release', 'start' and 'stop'
functions to the device commands.
Fix a long standing bug in scsi_command- the value in retsts is an integral
value- not a bitmask.
most significant change:
>make sure # of response matches # of queries, fixes int overflow; from ISS
as we have already enabled privsep by default, we should have been safe.
correct bad practice in the code - it uses two changing variables
to manage buffer (buf and buflen). we eliminate buflen and use
fixed point (ep) as the ending pointer.
this fix is critical.
16 SR registers when transitioning between kernel and user. Also, don't
reload the kernel SR(s) on every trap but only on traps from user space.
Instead of loading magic SRs for the kernel, load the kernel SRs from the
kernel_pmap_. This makes trap_subr.S completely ignorant of SR uses and
so they can change with having to change trap_subr.S. Also note that
since the user and kernel get complete SR sets, user VA space can now be
increased to 4GB if desired.
Note that we never use a PTE PP of 0 or 1 (supervisor protection) so the
"key" is basically unused. However, use SR_PRKEY for user space is
conceptionally the right thing to do. Currently the kernel_pmap SR(s) are
ignored but that is going to be fixed shortly.
an NFS root area for a diskless client. In such a situation, you
DO want the postinstall-check to be run.
The circumstances under which postinstall-check is now run:
* UNPRIVED is not set.
* The original target invoked was not distribution, release, or
snapshot.
make the number of available font slots variable,
set up a "quirk" mechanism to tell the generic vga code about crippled
VGA adapters which ignore the "fontsel" TS register,
initiate the quirk table with an ATI chip which happened to be on a board
I tested with.
Afaik quite a number of ATI chips suffers from the "loaded fonts don't
work" problem - these should be added.
Bad side effect of my change: The builtin font will be kicked out
always if a VGA_CONSOLE_SCREENTYPE is specified which needs a loaded
font. In early console initialization, we don't know much about the
graphics card, so we have to assume the worst (ie ATI:-).
