1.17   tsutsui 	-   TGA		RISCstation 2250, Express5800/230 R4400 PCI
1.29   tsutsui 			(TGA support in XalphaNetBSD just works,
1.29   tsutsui 			 but needs XOrg'fy)
 1.4      soda
1.17   tsutsui     o   Find out why bitmap load to S3-928 flashes screen. (X server)
1.17   tsutsui 	Know why (enable linear mode). Need S3 info.
 1.5      soda
 1.5      soda
1.27   tsutsui     o	repair DescStation support
1.11      soda 	-   requires bounce buffer bus_dma for Tyne

1.23   tsutsui     o	it is better to always disable the MIPS3 internal timer interrupts
1.23   tsutsui 	(i.e. MIPS_INT_MASK_5) if it is not needed for the system.
 1.9      soda 	those are the points which should be fixed:
 1.9      soda 	mips_idle: li t0, (MIPS_INT_MASK | MIPS_SR_INT_IE)
 1.9      soda 	machdep.c: curpcb->pcb_context[11] = MIPS_INT_MASK | MIPS_SR_INT_IE;
 1.9      soda 	spl0()
 1.9      soda 	splnone()
1.10      soda
1.17   tsutsui     o	XXX at least 2000/06/07 version is already quite unstable
1.17   tsutsui 	on PICA and NEC Image RISCstation. (but almost OK on Magnum)

1.11      soda
1.17   tsutsui 	currently, page zero in the idle loop is also disabled on
1.17   tsutsui 	untested platforms like DESKstation rPC44/Tyne and SNI for safety.
