Hi everyone, I'm having trouble to determine the cause of the following behavior. I'm not even sure that I'm supposed to hot plug and unplug a SATA drive from a nForce3 Ultra (apparently CK8S, on a Gigabyte K8NS Ultra 939 mobo) SATA interface, to begin with. The information is hard to find given that the sata_nv driver supports a range of different hardware. I've recently acquired an external drive with (among others) an eSATA interface, so I also bought a eSATA->SATA bracket and intend to u...

Honestly, this is the least interesting merge push I've had in a while. We're all doing debugging and such, so nothing major is below. I have some queued stuff (notably a sata_mv update) still to come, but this is the stuff that's been pending and in -mm for a while. Please pull from 'upstream-linus' branch of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/libata-dev.git upstream-linus to receive the following updates: drivers/ata/Kconfig | 9 + drivers/ata/Makefile ...

Is it normal that once I enable cpufreq on a tickless system, it spews a warning: Clocksource tsc unstable (delta = -288201154 ns) ? It's an old problem, and I was thinking about differences between x86-64 (it worked there) and i386 kernels. But with 2.6.24, x86-64 can run tickless as well, and once I enable this mode, and load dynamic cpufreq governor, the above message gets printed too. The system is amd x2-64, all kernels since tickless has been introduced. I'm not sure if it's rea...

Subject: x86: a new API for drivers/etc to control cache and other page attributes From: Arjan van de Ven <arjan@linux.intel.com> Right now, if drivers or other code want to change, say, a cache attribute of a page, the only API they have is change_page_attr(). c-p-a is a really bad API for this, because it forces the caller to know *ALL* the attributes he wants for the page, not just the 1 thing he wants to change. So code that wants to set a page uncachable, needs to be aware of the NX sta...

PAE mode requires that we reload cr3 in order to guarantee that changes to the pgd will be noticed by the processor. This means that in principle pud_clear needs to reload cr3 every time. However, because reloading cr3 implies a tlb flush, we want to avoid it where possible. pud_clear() is only used in a couple of places: - in free_pmd_range(), when pulling down a range of process address space, and - huge_pmd_unshare() In both cases, the calling code will do a a tlb flush anyway, so there'...

Deal properly with pmd-level pages being allocated and freed dynamically. We can handle them more or less the same as pte pages. Also, deal with early_ioremap pagetable manipulations.

Hi! I have just updated my server to 2.6.24 and the dl2k driver has stopped working. The problem seems to be when autoselecting the media, the driver says that the card is set as "Auto 1000 Mbps, Half duplex" instead of the usual "Auto 1000 Mbps, Full duplex", I have tried setting "options dl2k media=1000mbps_fd" but that didn't seem to change anything (the driver still said "Auto 1000 Mbps, Half duplex"). I've been playing with ethtools and got it to work at 100FD by setting it manually, but...

Yes. And I don't think there are instances of one place in the kernel removing pmd and then replacing it in short order. It either means you're doing a large munmap, or the pagetable is being destroyed (and Yes. Obviously any user of pud_clear must do some kind of tlb flush before they can expect the effect of their change to be visible. We just need to make sure that its the right kind of tlb flush that satisfies the processor's requirements for updating the pgd. If someone went and ...

Hm, but then chapter 10 goes and makes things confusing with "Alternative INVLPG Behavior"; but I guess if software needs to explicitly enable this behaviour in a yet-to-be-determined way, its OK... Is there any guide about the tradeoff of when to use invlpg vs flushing the whole tlb? 1 page? 10? 90% of the tlb? J --

Hi, here is the first release of patches for KVM to support the Nested Paging (NPT) feature of AMD QuadCore CPUs for comments and public testing.
