* [PATCH] vmi: paravirt drop udelay opZachary Amsden2007-03-05
| | | | | | | | | | | | | | | | | | Not respecting udelay causes problems with any virtual hardware that is passed through to real hardware. This can be noticed by any device that interacts with the real world in real time - like AP startup, which takes real time. Or keyboard LEDs, which should blink in real-time. Or floppy drives, but only when passed through to a real floppy controller on OSes which can't sufficiently buffer the floppy commands to emulate a zero latency floppy. Or IDE drives, when connecting to a physical CDROM. This was mostly a hack to get the kernel to boot faster, but it introduced a number of misvirtualization bugs, and Alan and Pavel argued pretty strongly against it. We were the only client, and now want to clean up this cruft.

* [PATCH] vmi: fix highpteZachary Amsden2007-03-05
| | | | | | | | | | | | | | | | | | | | Provide a PT map hook for HIGHPTE kernels to designate where they are mapping page tables. This information is required so the physical address of PTE updates can be determined; otherwise, the mm layer would have to carry the physical address all the way to each PTE modification callsite, which is even more hideous that the macros required to provide the proper hooks. So lets not mess up arch neutral code to achieve this, but keep the horror in an #ifdef HIGHPTE in include/asm-i386/pgtable.h. I had to use macros here because some types are not yet defined in all the include paths for this header. This patch is absolutely required for HIGHPTE kernels to operate properly with VMI.

* [PATCH] vmi: cpu cycles fixZachary Amsden2007-03-05
| | | | | | | | | | | | In order to share the common code in tsc.c which does CPU Khz calibration, we need to make an accurate value of CPU speed available to the tsc.c code. This value loses a lot of precision in a VM because of the timing differences with real hardware, but we need it to be as precise as possible so the guest can make accurate time calculations with the cycle counters.

* [PATCH] vmi: sched clock paravirt op fixZachary Amsden2007-03-05
| | | | | | | | | | | | | | | | | | | | | | | | The custom_sched_clock hook is broken. The result from sched_clock needs to be in nanoseconds, not in CPU cycles. The TSC is insufficient for this purpose, because TSC is poorly defined in a virtual environment, and mostly represents real world time instead of scheduled process time (which can be interrupted without notice when a virtual machine is descheduled). To make the scheduler consistent, we must expose a different nature of time, that is scheduled time. So deprecate this custom_sched_clock hack and turn it into a paravirt-op, as it should have been all along. This allows the tsc.c code which converts cycles to nanoseconds to be shared by all paravirt-ops backends. It is unfortunate to add a new paravirt-op, but this is a very distinct abstraction which is clearly different for all virtual machine implementations, and it gets rid of an ugly indirect function which I ashamedly admit I hacked in to try to get this to work earlier, and then even got in the wrong units.

* [PATCH] Page migration: Fix vma flag checkingChristoph Lameter2007-03-05
| | | | | | | | | | | | | | | | | Currently we do not check for vma flags if sys_move_pages is called to move individual pages. If sys_migrate_pages is called to move pages then we check for vm_flags that indicate a non migratable vma but that still includes VM_LOCKED and we can migrate mlocked pages. Extract the vma_migratable check from mm/mempolicy.c, fix it and put it into migrate.h so that is can be used from both locations.

* [PATCH] sched: remove SMT niceCon Kolivas2007-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | Remove the SMT-nice feature which idles sibling cpus on SMT cpus to facilitiate nice working properly where cpu power is shared. The idling of cpus in the presence of runnable tasks is considered too fragile, easy to break with outside code, and the complexity of managing this system if an architecture comes along with many logical cores sharing cpu power will be unworkable. Remove the associated per_cpu_gain variable in sched_domains used only by this code. Also: The reason is that with dynticks enabled, this code breaks without yet further tweaks so dynticks brought on the rapid demise of this code. So either we tweak this code or kill it off entirely. It was Ingo's preference to kill it off. Either way this needs to happen for 2.6.21 since dynticks has gone in.

* [PATCH] msi: sanely support hardware level msi disablingEric W. Biederman2007-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases when we are not using msi we need a way to ensure that the hardware does not have an msi capability enabled. Currently the code has been calling disable_msi_mode to try and achieve that. However disable_msi_mode has several other side effects and is only available when msi support is compiled in so it isn't really appropriate. Instead this patch implements pci_msi_off which disables all msi and msix capabilities unconditionally with no additional side effects. pci_disable_device was redundantly clearing the bus master enable flag and clearing the msi enable bit. A device that is not allowed to perform bus mastering operations cannot generate intx or msi interrupt messages as those are essentially a special case of dma, and require bus mastering. So the call in pci_disable_device to disable msi capabilities was redundant. quirk_pcie_pxh also called disable_msi_mode and is updated to use pci_msi_off. Signed-off-by: Eric W.

The commit 35068976916fdef82d6e69ef1f8c9a1c47732759 solved this in a way that it didn't remap certain usages. This however breaks (at least) middle button of Logic3 / SpectraVideo (0x1267/0x0210), which in contrary requires the remapping. To make both of the harware work, allow remapping of these usages again, and introduce a quirk for Logitech DiNovo Edge "touchwheel" instead - we disable remapping for key, abs and rel events only for this hardware.

| * HID: fix broken Logitech S510 keyboard report descriptor; make extra keys workJiri Kosina2007-03-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes extra keys (F1-F12 in special mode, zooming, rotate, shuffle) on Logitech S510 keyboard work. Logitech S510 keyboard sends in report no. 3 keys which are far above the logical maximum described in descriptor for given report. This patch introduces a HID quirk for this wireless USB receiver/keyboard in order to fix the report descriptor before it's being parsed - the logical maximum and the number of usages is bumped up to 0x104d). The values are in the "Reserved" area of consumer HUT, so HID_MAX_USAGE had to be changed too. In addition to proper extracting of the values from report descriptor, proper HID-input mapping is introduced for them. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

Peter Anvin states, this change broke klibc and it's not very easy to fix things up without duplicating everything into userspace. In the longer term we should have a better solution to this problem, but for now let's unbreak things. Signed-off-by: David S. Miller <davem@davemloft.net>
