On Wed, 30 Apr 2008 17:02:02 +0200 I'm not an expert in this, but one thing is that the more memory the system has, the more overhead there is. yes this is expected. Let me explain: even though you have 4Gb of memory, it's spread out like this: 0 - 3.5Gb Memory 3.5Gb - 4Gb Gap 4Gb - 4.5Gb Memory This "gap" is needed for PCI. PCI devices have "memory" on them (technical term is "MMIO", memory mapped IO) and this needs to be in the first 4Gb of memory (traditionally). So the system l...

On Wed, 30 Apr 2008 16:17:46 +0100 (BST) this is how it always was supposed to be! At least this is how Intel specifies it to the BIOS vendors (but remember, it's the bios that pretty much sets the cpu order; some will be weird). Exactly for the maxcpus=2 reason... (and for systems where the cpu scheduler does load balancing "from 0 up" it also makes sense) --

On Wed, 30 Apr 2008 01:29:51 +0300 It will get used once the olpc power management code makes it upstream. The olpc_register_battery_callback stuff that Andrew removed was related to that. Remove it now if you like, but I'm hoping to get it in for the 2.6.27 merge window. --

On Tue, Apr 29, 2008 at 5:50 PM, Mauro Carvalho Chehab Linus has already merged the changes (thank you, Linus) ... However, there is a bug. My "remove static dependencies on analog tuner sub-modules" patch was applied after Mauro's "Rename common tuner Kconfig names to use the same" patch. My patch has conditional behavior, based on CONFIG_DVB_CORE_ATTACH, which was renamed to CONFIG_MEDIA_ATTACH in Mauro's patch. To fix this, we need to do: sed -i s/"CONFIG_DVB_CORE_ATTACH"/"CONFIG_M...

Hello, I have released the perfmon2 kernel patch for kernel v2.6.25. There is no major features. However, there were a major restructuring of the code to make it more readable, isolate features per module. The header files have also been restructured to separate user vs. kernel, and generic only vs. shared with arch. The restructuring of the interrupt handler yielded a nice 15% latency improvement on single counter sampling runs on X86. This new structure will make it easier to extract featu...

From: Helge Wagner <Helge.Wagner@gefanuc.com> On some of our (single board computer) boards (x86) we are using an IPMI controller that uses I/O ports 0x62 and 0x66 for a KCS (keyboard controller style) IPMI system interface. Trying to load the openipmi driver fails, because the ports (0x62/0x66) are reserved for keyboard. keyboard reserves the full range 0x60-0x6F while it doesn't need to. Reserve only ports 0x60 and 0x64 for the legacy PS/2 i8042 keyboad controller instead of 0x60-0x6F...

I like to use display names for email addresses, e.g., "Bjorn Helgaas <bjorn.helgaas@hp.com>" instead of just "bjorn.helgaas@hp.com". The current MAINTAINERS file format makes it a nuisance to copy both the display name and the actual address. So I propose that we fold together the current "P:" and "M:" lines using something similar to the filter below. If we do this, we should fix a few inconsistencies in the current file first so the script will work better. I'll post a patch to do th...

Since it depends on pca9532-led-driver being added first, I believe it would logistically simpler to get both patches through leds tree. -- "rm -rf" only sounds scary if you don't have backups --

Agreed, I'll take them in the LED tree then after I've had a closer look at the driver tomorrow. The LED tree has already merged for this development cycle though so it will have to be queued for the next one. Cheers, Richard --

Oh, yet more surprise code apparantly submitted and as yet unreviewd during the merge window! ;( Looks sane enough. I don't see it really matters.
