MFC: Allow syscons to work on amd64 and i386 without any hints.

It seems that some i386 mothermoards either do not implement the

2007-07-27T09:34:42Z

day of week field correctly, or they remember bad values that are written into the day of week field. For this reason, ignore the day of week field when reading the clock on i386 rather than bailing if it is set incorrectly. Problems were seen on a number of platforms, including VMWare, qemu, EPIA ME6000, Epox-3PTA and ABIT-SL30T. This is a slightly different fix to that proposed by Ted in his PR, but the same basic idea. PR: 111117 Submitted by: Ted Faber Approved by: re (rwatson) MFC after: 3 weeks

If clock_ct_to_ts fails to convert time time from the real time clock,

Prototype (but functional) Linux-ish /dev/nvram interface to the extra

114 bytes of cmos ram in the PC clock chip. The big difference between this and the Linux version is that we do not recalculate the checksums for bytes 16..31. We use this at work when cloning identical machines - we can copy the bios settings as well. Reading /dev/nvram gives 114 bytes of data but you can seek/read/write whichever bytes you like. Yes, this is a "foot, gun, fire!" type of device.

Despite several examples in the kernel, the third argument of

sysctl_handle_int is not sizeof the int type you want to export. The type must always be an int or an unsigned int. Remove the instances where a sizeof(variable) is passed to stop people accidently cut and pasting these examples. In a few places this was sysctl_handle_int was being used on 64 bit types, which would truncate the value to be exported. In these cases use sysctl_handle_quad to export them and change the format to Q so that sysctl(1) can still print them.

When trying to allocate a PnP BIOS memory resource, the code loops trying

to move up the start address until the allocation succeeds. If the alignment of the resource was 0, then the code would keep trying the same request in an infinite loop and hang. Force the request to always move start up by at least 1 byte each time through the loop.

Partial fix for a bug in rev.1.231. If suspend/resume clobbers the

RTC state, then it may clobber the RTC index register, so the index register must be restored before using it to restore control registers in rtc_restore(). The following problems remain: - rtc_restore() is only called if pmtimer is configured. Buggy suspend/resumes are more likely to clobber the index register than a control register, so pmtimer is more needed than it used to be. - pmtimer doesn't exist for amd64. - Restoring of the RTC state may race with rtcintr(). If an RTC interrupt is handled before the state is restored, then rtcin(RTC_INTR) in rtcintr() may read from the wrong register, so rtcintr() may spin forever. This may be mitigated by the most common state clobbering being to turn off RTC interrupts.
