Hi, Thank you for your comments. > I've added an acpi_hpet.h after looking at this PR though it's a bit > different. The current stuff in CVS doesn't have the user timer driver to > allow user processes to use HPET timers, but I'm not sure if we really want > that. > IIRC, phk works about new callout facility which uses high precision timer facility(i.e. HPET etc...). The new timer facility may be good replacement of timer drivers for user lands(rtc driver in ports uses callout, so new timer facility may improve user land timer if it is really needed.). So I think that this PR can be closed. But some people sent e-mails to me, and these people seems to want timer driver for user lands to some extent(Some multimedia player (i.e. mplayer) uses user land periodic timer at least.) Regards,
