of the new I2C code.)
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals
kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)
based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe
add rd, pc, #foo - . - 8 -> adr rd, foo
ldr rd, [pc, #foo - . - 8] -> ldr rd, foo
Also, when saving the return address for a function pointer call, use
"mov lr, pc" just before the call unless the return address is somewhere
other than just after the call site.
Finally, a few obvious little micro-optimisations like using LDR directly
rather than ADR followed by LDR, and loading directly into PC rather than
bouncing via R0.
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
u_int16_t and int16_t for the X and Y count registers. GCC produces better
code this way.
Also, initialise the stored state in wsqms_enable(), so that the mouse doesn't
warp to a random position on open.
sc_flags was never read. G/C it.
wsqms_attach() took two arguments that pointed to the same structure. G/C one
of them
Since wsqms controls the same device as qms, have it match the same attach
args.
Use a callout rather than hanging off the VSYNC interrupt.
Don't emit WSMOUSE_INPUT_ABSOLUTE events, since this isn't an absolute device.
Handle counter wrap-around sensibly, rather than limiting counts.
Don't gratuitously copy sc->sc_dev onto itself at attach time.
the palette generation to work with arbitrary numbers of bits.
This allows X to work after a fashion, since it tries to put the VIDC into
a 6:5:5 mode itself (which we ignore). Anything that actually tries to take
advantage of the DirectColor visual it offers will still be screwed, but I
hope such applications are rare.
This time, vidcvideo_stdpalette() uses vidcvideo_write(), as it should, and
correctly initialises the paletter in 16bpp and (I hope) 32 bpp modes.
This fixes the colours on the text console in 16bpp modes. 32bpp seems to be
generally broken anyway.
to set it, and vidcprint isn't needed to print it. G/C all that code, and
most of the rest of vidcsearch too.
This also means that the locators on vidc's children are unused, so G/C them
as well.
