old-style pmax polled input for cn_getc(). Needed because the
input side of rcons is not initialized in time for GENERIC kernels
to use it to read a root/swap devicename from /dev/console.
a) check against `my' ethernet or broadcast addresses done in
ether.c
b) changed interface to readether() to provide ethertype info
c) respond to arp requests when appropriate.
First two are clean-up. Last fixes hp300 and presumably mvme68k netboot
code.
When not in a function, it skips the rest of the current input file.
Instances of `return' outside function definitions were previously ignored.
What does joe posix have to say about this?
[fixes PR/1444]
"struct pmax_device" to avoid conflict with <sys/device.h>.
Change the signature of interrupt-handlers to take a void *
(a pointer to the softc) and return an int (indicating spurious
interrupts or other conditions.)
NetBSD/sparc rcons glass-tty console pseudo-device driver, via
the "fb" generic-framebuffer pseudo-device driver.
Individual framebuffer device drivers are now autoconfig glue,
and initialization code for a set of vdac/ramdac-level methods,
called "fbdriver", that's used by all the pmax device drivers.
All the handlers for user-level requests (open/ioctl/read/write/close)
are moved into the fb pseudo-device driver, which uses the
the "fbdriver" methods to work on any given pmax hardware driver.
Framebuffers supported are: sfb cfb mfb xcfb pm.
Move the qvss (pm) -style mmap()ed device interface, kernel tracking
of mouse button/movement events, and placing mouse/keyboard
events in an mmap()ed ring buffer, out of the framebuffer device
drivers and into separate source files. The fb pseudo-device driver
uses the qvss-compatible interface, since that's what the (R5) X
server uses.
Dependency rules with `=' in the lhs are parsed as variable assignments.
E.g., the following Makefile fails:
A=a b c d
all: $(A:%=%b)
$(A:%=%b):
@echo $@
Correct handling of rmdir'ing open directories
Correct implementation of rename (includes renaming of directories)
Handle root directories that are not multiple clusters in size
