[PATCH] DSDT: Fix HPET _CRS Method
by Gabriel L. Somlo 19 Nov '12

19 Nov '12

Updated _CRS method for HPET, bringing it in line with the way it is presented on recent hardware (e.g. Dell Latitude D630, MacPro5,1, etc); Allows it to be detected and utilized from Mac OS X; Also tested OK on Linux (F16 64-bit install DVD) and Windows (Win7 64-bit install DVD).

We could introduce hotunplug as an experimental feature so people can test and play with it, and later graduate it to a fully supported feature. -- error compiling committee.c: too many arguments to function

IMO we should use the same mechanism as proposed for other devices: address_space_map() should grab a reference on the dimm device, and address_space_unmap() can release it. This way device destruction will be deferred as soon as all devices complete I/O. We will have to be careful with network receive buffers though, since they can be held indefinitely. -- error compiling committee.c: too many arguments to function

Hi Vasilis, Regarding the hot unplug issue we've been discussing, it's possible to progress this patch series without fully solving that problem upfront. Karen Noel suggested that the series could be rolled without the hot unplug command, so that it's not possible to hit the unsafe case. This would allow users to hot plug additional memory. They would have to use virtio-balloon to reduce the memory footprint again. Later, when the memory region referencing issue has been solved the hot unplug command can be added. Just wanted to mention Karen's idea in case you feel stuck right now. Stefan

doe's seabios support retry booting from other disk if boot from one disk failed
by Eli 29 Oct '12

29 Oct '12

hi all: Does anyone know that if seabiso support booting from other disk if boot from one failed ? For instance, the PC BIOS boot specification allows only one disk to be bootable. If boot from disk fails for some reason, the BIOS won't retry booting from other disk. It still can try to boot from floppy or net, though.I want to know that if seabios support retry booting from other disk? Thanks Eli.
