As usual we forget to update SeaBIOS. We probably want these two from Gerd: 7d05257 (lsi: enable busmaster, 2012-11-20) 455a7c8 (add acpi pmtimer support, 2012-09-06) and a matching patch to enable bus master DMA in esp.c (just submitted). The choice is between committing these three patches on top of 1.7.1, or just picking the top of the SeaBIOS tree. There hasn't been much action since 1.7.1 (mostly SeaVGABIOS changes), so I prefer the latter. Kevin, are you okay with tagging SeaBIOS master as 1.7.2 one of these days? Other opinions? Paolo

A new release can be produced if desired. Given that there isn't much new since 1.7.1 I too would prefer to just push forward to 1.7.2. -Kevin

Agree. I'll prepare a seabios update pull once the tag is there. cheers, Gerd

Ping? Meanwhile 1.4 freeze is in sight (soft freeze in one week, hard freeze + -rc0 feb 1st). cheers, Gerd

Lets target Jan 18th for the next SeaBIOS release. -Kevin

Why is 1.4 being rushed so quick? Is this because 1.3.0 was so broken or is there something else? -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

I don't understand your questions. The 1.4 release is for QEMU and I don't control its release schedule. -Kevin

Of course the 1.4 release is for QEMU, that's pretty obvious. Sorry the question wasn't necessarily for you. I just noticed what was quoted when you had replied. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Anthony decides, as release manager. One reason I recall, is that releases in Mar/Jun/Sep/Dec do not work well with Fedora and Ubuntu freeze dates. Feb/May/Aug/Nov should work a little better. Paolo
