remove some old minix-userland-specific stuff
. /etc/ttytab as a file, and minix-compat function (fftyslot()),
replaced by /etc/ttys and new libc functions
. also remove minix-specific nlist(), cuserid(), fttyslot(), v8 regex
functions and <compat/regex.h>
. and remaining minix-only utilities that use them
. also unused <compat/pwd.h> and <compat/syslog.h> and
redundant <sys/sigcontext.h>
. common/include/arch/i386 is not actually an imported
sys/arch/i386/include but leftover Minix files;
remove and move to include/
. move include/ufs to sys/ufs, where it came from, now that
we have a sys/ hierarchy
. move mdocml/ to external/bsd/, now we have that
. single sys/arch/i386/stand/ import for boot stuff
- add files needed for acpi, ahci, fbd, vfs to libminc
- remove "-lc" from their respective makefiles
- remove setenv from libminc (requires initialization)
- remove PCI tables where system.conf suffices
- remove drivers' ability to mess up NIC order
- fix dp8390 PCI enumeration
- convert ti1225 to instance model
- add system.conf entry for ti1225
On MFS file systems, the stat(2) call now counts indirect blocks as
part of the st_blocks calculation, in addition to proper initial
rounding of the file size. The returned value is now a true upper
bound on the actual number of 512-byte blocks allocated to the file.
As before, it is not accurate for sparse files.
On the x86, saving FPU state has the side effect of resetting this
state. In some cases (fork, getcontext), this would cause the state
to be lost. This patch restores the FPU state right after saving it,
except when different state is loaded immediately after.
Previously, user processes could cause a kernel panic upon FPU state
restore, by passing bogus FPU state to the kernel (through e.g.
sigreturn). With this patch, the process is now sent a SIGFPE signal
instead.
- libnetsock - internal implementation of a socket on the lwip
server side. it encapsulates the asynchronous protocol
- lwip server - uses libnetsock to work with the asynchronous
protocol
- if an operation (R, W, IOCTL) is non blocking, a flag is set
and sent to the device.
- nothing changes for sync devices
- asyn devices should reply asap if an operation is non-blocking.
We must trust the devices, but we had to trust them anyway to
reply to CANCEL correctly
- we safe sending CANCEL commands to asyn devices. This greatly
simplifies the protocol. Asynchronous devices can always reply
when a reply is ready and do not need to deal with other
situations
- currently, none of our drivers use the flags since they drive
virtual devices which do not block
- select_request_async() returns no ops by default
- wantops in do_select() always set correctly, do_select() does
not need a special case for SUSPEND (and ugly code)
The NetBSD boot loader loads automatically the kernel module appropriate
for the detected root file system; it is preset at "ffs". The MINIX3fs
support does not reset the underlying global variable, since there are
no use for this on MINIX. As a result, the boot loader searches for
/ffs.kmod, and issues two warnings about "module failure to open/load."
