in the drive. restrict "opening of empty drive" to character devices only
(reading a block device returns a short read instead of ENODEV, which can lead
to confusion).
1. If the current screen becomes invalid (ie no focus anymore), always
set the keyboard to translating mode. Otherwise, we could get stuck
because the command keystokes don't come through.
2. Catch errors in attaching to a process (X server) - For this,
implement a callback mechanism similar to the detach case. Add an
argument to report an errno via callback.
might be called without process context, leading to tsleep() panics
(This is a workaround. The timeout() driven wscons glue code
should go instead.)
Fixes tsleep() panics reported by Mark Brinicombe <mark@causality.com>
and Eric Haszlakiewicz <haszlaki@UAccess.NET>.
out-dated comments, and other unneeded stuff. This helps prepare
for cleaning up the rest of the code, and adding new functionality.
No functional changes to the kernel code in this commit.
Thanks to Scott for pointing this out to me (I got his mail and figured out
this change before seeing the discussion on tech-kern) and to Charles for
the initial explanation.
(Nonaka Kimihiro): grave accent and @ were the wrong way
-assign keysyms to the special japanese conversion keys (even if this
doesn't help wscons - but things must have names)
In wdc_probe_caps() add code to guess the ATA revision supported (if
ATA4 if Ultra-DMA, ATA2 if PIO mode > 2). We can't rely on param.atap_ata_major
here, at last one Ultra-DMA drive claims to support only ATA-3.
Use the ATA version in ata_perror(), and to try a flush cache command
in a shutdown hook for IDE drives.
add handling of a "close all" command
-split out code common with wsdisplay_delscreen() into
wsdisplay_closescreen()
-add ttymodem call to signal a HUP to the application if the screen
is closed
-add flag to force a "clear screen" on close (XXX should actually be
controlled from userland)
-remove checks for existence of "reset" entries in the emulations - this
is required now
