Dave Hansen [Mon, 11 Aug 2008 17:01:45 +0000]
KVM: Reduce kvm stack usage in kvm_arch_vm_ioctl()

On my machine with gcc 3.4, kvm uses ~2k of stack in a few
select functions.  This is mostly because gcc fails to
notice that the different case: statements could have their
stack usage combined.  It overflows very nicely if interrupts
happen during one of these large uses.

This patch uses two methods for reducing stack usage.
1. dynamically allocate large objects instead of putting
   on the stack.
2. Use a union{} member for all of the case variables. This
   tricks gcc into combining them all into a single stack
   allocation. (There's also a comment on this)

KVM: pci device assignment

Based on a patch from: Amit Shah <amit.shah@qumranet.com>

This patch adds support for handling PCI devices that are assigned to
the guest.

The device to be assigned to the guest is registered in the host kernel
and interrupt delivery is handled.  If a device is already assigned, or
the device driver for it is still loaded on the host, the device
assignment is failed by conveying a -EBUSY reply to the userspace.

Devices that share their interrupt line are not supported at the moment.

By itself, this patch will not make devices work within the guest.
The VT-d extension is required to enable the device to perform DMA.
Another alternative is PVDMA.

x86: KVM guest: use paravirt function to calculate cpu khz

We're currently facing timing problems in guests that do
calibration under heavy load, and then the load vanishes.
This means we'll have a much lower lpj than we actually should,
and delays end up taking less time than they should, which is a
nasty bug.

KVM: PIT: fix injection logic and count

The PIT injection logic is problematic under the following cases:

1) If there is a higher priority vector to be delivered by the time
kvm_pit_timer_intr_post is invoked ps->inject_pending won't be set.
This opens the possibility for missing many PIT event injections (say if
guest executes hlt at this point).

2) ps->inject_pending is racy with more than two vcpus. Since there's no locking
around read/dec of pt->pending, two vcpu's can inject two interrupts for a single
pt->pending count.

Fix 1 by using an irq ack notifier: only reinject when the previous irq
has been acked. Fix 2 with appropriate locking around manipulation of
pending count and irq_ack by the injection / ack paths.

12 years agortc-cmos: look for PNP RTC first, then for platform RTC
Bjorn Helgaas [Tue, 14 Oct 2008 23:01:59 +0000]
rtc-cmos: look for PNP RTC first, then for platform RTC

We shouldn't rely on "pnp_platform_devices" to tell us whether there
is a PNP RTC device.

I introduced "pnp_platform_devices", but I think it was a mistake.
All it tells us is whether we found any PNPBIOS or PNPACPI devices.
Many machines have some PNP devices, but do not describe the RTC
via PNP.  On those machines, we need to do the platform driver probe
to find the RTC.

We should just register the PNP driver and see whether it claims anything.
If we don't find a PNP RTC, fall back to the platform driver probe.

This (in conjunction with the arch/x86/kernel/rtc.c patch to add
a platform RTC device when PNP doesn't have one) should resolve
these issues:

12 years agox86: register a platform RTC device if PNP doesn't describe it
Bjorn Helgaas [Tue, 14 Oct 2008 23:01:03 +0000]
x86: register a platform RTC device if PNP doesn't describe it

Most if not all x86 platforms have an RTC device, but sometimes the RTC
is not exposed as a PNP0b00/PNP0b01/PNP0b02 device in PNPBIOS or ACPI:

    http://bugzilla.kernel.org/show_bug.cgi?id=11580
    https://bugzilla.redhat.com/show_bug.cgi?id=451188

It's best if we can discover the RTC via PNP because then we know
which flavor of device it is, where it lives, and which IRQ it uses.

But if we can't, we should register a platform device using the
compiled-in RTC_PORT/RTC_IRQ resource assumptions.

Anssi Hannula [Sat, 4 Oct 2008 12:44:06 +0000]
HID: fix a lockup regression when using force feedback on a PID device

Commit 8006479c9b75fb6594a7b746af3d7f1fbb68f18f introduced a spinlock in
input_dev->event_lock, which is locked when handling input events.
However, the hid-pidff driver sleeps when handling events as it waits for
reports being sent to the device before changing the report contents
again.
This causes a system lockup when trying to use force feedback with a PID
device, a regression introduced in 2.6.24 and 2.6.23.15.

Fix it by extracting the raw report data from struct hid_report
immediately when hid_submit_report() is called, therefore allowing
drivers to change the contents of struct hid_report immediately without
affecting the already-queued transfer.

In hid-pidff, re-add the removed usbhid_wait_io() to
pidff_erase_effect() instead, to prevent a full report queue from causing
the submission to fail, thus not freeing up device memory.
pidff_erase_effect() is not called while dev->event_lock is held.

Richard Hughes [Wed, 27 Aug 2008 09:19:37 +0000]
HID: remove ignore quirk for MGE UPS devices

This patch reverts the change made four years ago here:
http://www.vg.kernel.org/pub/linux/kernel/people/gregkh/usb/2.4/usb-hid-2.4.25-pre7.patch

UPS's made by MGE can be used with usbhid just fine, and by removing the
ignore quirk allows them to be used with HAL so they just work when plugged
in, without needing to be manually configured.

With the ignore quirk in place a user would have to configure NUT before the
UPS could be used, as NUT uses it's own internal USB matching framework
to match against the USB devices, do low level control messages on the
device and then parse the HID tables all in userspace.

This is not needed, as allowing the device to be claimed as a usbhid device
allows it to be used like any other USB UPS device. The devices correctly
advertise the power device page which can be queried for the device state.

I assume the quirk was changed so that people using < libusb 0.1.8 could
still use NUT's internal HID code to manage the UPS.
libusb 0.1.8 was released quite some time ago: 2004-02-11.

This patch does not break NUT as in drivers/libusb.c the device is force
unbound from the kernel driver using usb_detach_kernel_driver_np () where
it can be controlled like normal.

HID: make a bus from hid code

Make a bus from hid core. This is the first step for converting all the
quirks and separate almost-drivers into real drivers attached to this bus.

It's implemented to change behaviour in very tiny manner, so that no driver
needs to be changed this time.

Also add generic drivers for both usb and bt into usbhid or hidp
respectively which will bind all non-blacklisted device. Those blacklisted
will be either grabbed by special drivers or by nobody if they are broken at
the very rude base.
