altos: Make stdio 8-bit clean by making pollchar return int

2012-12-01T00:01:07+00:00

We were stealing one value (0xff) in the return value from pollchar to indicate 'not ready yet'. Instead of doing that, use the integer value -1 and have pollchar return an int instead of a char. That necessitated cleaning a few other bits to make sure that 0xff wouldn't get promoted to -1 on accident. Signed-off-by: Keith Packard

altos: Leave interrupts disabled while checking for task to run

2012-10-26T21:07:04+00:00

Otherwise, we run the risk of an interrupt waking a task after we've decided to idle the CPU. Signed-off-by: Keith Packard

altos: Add ao_arch_block/release_interrupts to avr and cc1111

2012-10-25T07:07:14+00:00

Stop using cli/sei for AVR, add replacement to __critical for cc1111 Signed-off-by: Keith Packard

altos: Let AVR products override the stack size. Set telepyro to 104

2012-10-23T04:37:25+00:00

Otherwise, telepyro doesn't have enough ram... Signed-off-by: Keith Packard
