@ -0,0 +1,35 @@
To do list (not in any particular order).
o Improve pmap_zero_page and pmap_copy_page. Speed and flushing.
o Move the RO and WIRED attribute from the pte to the pv table.
This saves four instructions in the tlb miss handler.
InWork: Have a test version. The system hangs after a while. Not solved yet.
Also, is it worth the effort to remove 4 instr. in TLB-miss handler?
o Update MAKEDEV to create all devices correctly.
o Boot. Standalone boot program instead of booting the kernel directly?
o Create boot package for distribution.
o sigsetjmp/siglongjmp missing....
o Add more videomodes to pccons driver. 50kHz and 64kHz monitors?
InWork: This seems to be hard. Need more info on the chip.
o Find out why bitmap load to S3-928 flashes screen.
Know why (enable linear mode). Need S3 info.
o Would be nice to have Motif...
o ELF shared libraries......
o GDB. The current one does not work correctly with current toolchain.
o ISA driver. ISA dma, interrupt etc.
o Can we have 32 double registers?
Lots of other things.....

/*
* Register definitions for the Intel 8253 Programmable Interval Timer.
*
* This chip has three independent 16-bit down counters that can be
* read on the fly. There are three mode registers and three countdown
* registers. The countdown registers are addressed directly, via the
* first three I/O ports. The three mode registers are accessed via
* the fourth I/O port, with two bits in the mode byte indicating the
* register. (Why are hardware interfaces always so braindead?).
*
* To write a value into the countdown register, the mode register
* is first programmed with a command indicating the which byte of
* the two byte register is to be modified. The three possibilities
* are load msb (TMR_MR_MSB), load lsb (TMR_MR_LSB), or load lsb then
* msb (TMR_MR_BOTH).
*
* To read the current value ("on the fly") from the countdown register,
* you write a "latch" command into the mode register, then read the stable
* value from the corresponding I/O port. For example, you write
* TMR_MR_LATCH into the corresponding mode register. Presumably,
* after doing this, a write operation to the I/O port would result
* in undefined behavior (but hopefully not fry the chip).
* Reading in this manner has no side effects.
*
* The outputs of the three timers are connected as follows:
*
* timer 0 -> irq 0
* timer 1 -> dma chan 0 (for dram refresh)
* timer 2 -> speaker (via keyboard controller)
*
* Timer 0 is used to call hardclock.
* Timer 2 is used to generate console beeps.
