all devices on the bus are really reset.
- Block interrupts on Bus Reset, and check it periodically until the
reset is released. On some 32UDE devices (probably the earlier ones)
the RST line looks unstable without the termination power and may
suffer ~continuous Bus Reset interrupts.
- Change number of scatter/gather segments from 16 to 17, to allow
non-page-aligned 64KB transfer on 4KB/page platforms.
introduce ENVSYS_BATTERY_CHARGE, which is the same than an Indicator and
it's used to know if the battery is currently charging or discharging.
- Require two sensors at least for SME_CLASS_BATTERY to make the low-power
condition work: a ENVSYS_BATTERY_CAPACITY plus ENVSYS_BATTERY_CHARGE.
- Simplify sme_event_check_lowpower() and make it check the required
sensors in the SME_CLASS_ACADAPTER and SME_CLASS_BATTERY classes.
If the acadapter is not ready, trust the state returned by the battery
device.
Based on suggestion from joerg@.
softc no longer contains 'struct device' by default
use 'device_t' instead of 'struct device *'
use device_xxx() accessor functions
remove casting of 'xxx_softc *' & 'struct device *'
use aprint_xxx_dev() routines
change from an adaptive to spin mutex @ IPL_TTY. This seems to mitigate
or eliminate a lot of locking-related issues (such as a hang when running
glxgears under AIGLX). Tested by me and Vincent <10.50@free.fr>.
In this code, we have three locks: irq, dma, and device. If anyone has
any thoughts on how to improve this situation, e.g. by using different
lock types/priorities/soft interrupts/etc. for different locks, please
share them with me.
NOTE: I've had the best results thusfar using Mesa 7.0.2-rc1 (r300 users
could even try the r300 driver code from the master branch) and xorg-server
1.4+patches from GIT.
- make sure to set HD_ROW1_ADDR before putting characters at the first line
in hd44780_ddram_redraw()
- use memmove(9) rather than bcopy(9) for possibly overlapped copies
If you have a system where it doesn't get one and you still want pcic,
you can just disable cbb. This check is invalid as soon as the PCI
interrupt register is not used and broke on my Dell Latitude for that
reason.
