have to adjust for whether he have a "small" or "large" mode sense response.
sd_scsibus_getcache(), sd_scsibus_setache(): Set SMS_DBD so that we don't
have to deal with block descriptors here.
sd_scsibus_mode_sense(): Add a new parameter, "int *big", which tells the
caller whether it's a small or large header.
sd_scsibus_get_parms(), sd_scsibus_getcache(), sd_scsibus_setcache(): Use
the "big" value to find the data following the mode sense header correctly.
sd_scsibus_mode_sense(): Disable PQUIRK_NOBIGMODESENSE for now, as the
reasons for it were dubious and most likely fixed now.
sd_scsibus_get_parms(): Now that we're actually locating the right data,
check the returned page code to see if it's correct before using the mode
page info.
sd_scsibus_get_parms(): Get the rotational rate from the flex geometry page
too, if present.
XXX sd_scsibus_get_{opt,simplifiedparms}() need some work.
PCIC_VENDOR_NONE: New.
PCIC_VENDOR_CIRRUS_*: Collapse the 2 chips into one vendor ID.
pcic_ident_ok(): Check the ID revision field -- if it's 0, punt.
pcic_vendor(): Check the ID revision field -- if it's 0, or the ID register
is all-1s, assume there is no chip present. (Previously this would return
"Unknown controller" -- which, AFAICT, *never* resulted in a working device.)
Do the Cirrus check only after verifying that we got the Intel ID.
pcic_attach(): Use a priori knowledge of the Cirrus chips to determine the
number of sockets rather than trying (unsuccessfully) to probe. Also, just
blast all of PCIC_INTR -- we do this in pcic_deactivate_card() anyway.
* Use the "block descriptor length" to find the beginning of the mode page
data. This is critical, since some devices do not return a block descriptor
at all. (XXX There is disgusting structure hackery here.)
* Always use scsipi_size() (i.e. READ CAPACITY) to get the total disk size.
* Get the rotational rate from the rigid geometry page.
* Don't read the block size from the block descriptor if there was none.
* Get the block size from the flexible geometry page if possible.
* If we don't like the way page 4 smells, try page 5, rather than just punting.
every field; some need to stay around.
Fixes a bug where by calling shutdown() on a socket with knotes
will cause the kernel to panic when the kernel closes the socket.
Other access, such as calling kevent() may also trigger the panic.
Debugged with help from Jason and Allen. Patch reviewed by same plus
Itojun and Matt Thomas.
This problem seems to be the same one that FreeBSD saw in their PR
number 54331.
Kernel version _not_ bumped as we will piggyback the bump earlier today.
Fix strncmp(x, y, 0)
Use unsigned compares for strcmp and memcmp (and bcmp).
Compiles but untested
AFAICT http://h71000.www7.hp.com/doc/72final/4515/4515pro_025.html#4515ch9_146
cmpc3/5 set %r4 and %r5 to zero, It doesn't look as though the procedure
call is set to preserve these, and I doubt that gcc is treating them as
scratch registers - does our vax pcs actually have %r2 and %r3 as scratch regs?
the order that Makefile.inc is pulled in to get this to work.
this stuff needs a rototill (for another day). for example, having every
sys/lkm/** directory make their own machine ${MACHINE_CPU} and possibly
${SHARED_MACHINE_CPU} (e.g, x86 for i386/x86_64) is not the most optimal
situation ...
