As we execute real mode guests in VM86 mode, exception have to be reinjected appropriately when the guest triggered them. For this purpose the patch adopts the real-mode injection pattern used in vmx_inject_irq to vmx_queue_exception, additionally taking care that the IP is set correctly for #BP exceptions. Furthermore it extends handle_rmode_exception to reinject all those exceptions that can be raised in real mode. This fixes the execution of himem.exe from FreeDOS and also makes its debug.com work properly. Note that guest debugging in real mode is broken now. This has to be fixed by the scheduled debugging infrastructure rework (will be done once base patches for QEMU have been accepted).

Instead of looking at failed injections in the vm entry path, move processing to the exit path in vmx_complete_interrupts(). This simplifes the logic and removes any state that is hidden in vmx registers. Signed-off-by: NAvi Kivity <avi@qumranet.com>

The vmx code assumes that IDT-Vectoring can only be set when an exception is injected due to the exception in question. That's not true, however: if the exception is injected correctly, and later another exception occurs but its delivery is blocked due to a fault, then we will incorrectly assume the first exception was not delivered. Fix by unconditionally dequeuing the pending exception, and requeuing it (or the second exception) if we see it in the IDT-Vectoring field. Signed-off-by: NAvi Kivity <avi@qumranet.com>

If we're emulating an instruction, either it will succeed, in which case any previously queued exception will be spurious, or we will requeue the same exception. Signed-off-by: NAvi Kivity <avi@qumranet.com>

Instead of processing nmi injection failure in the vm entry path, move it to the vm exit path (vm_complete_interrupts()). This separates nmi injection from nmi post-processing, and moves the nmi state from the VT state into vcpu state (new variable nmi_injected specifying an injection in progress).

Currently most interrupt exit processing is handled on the entry path, which is confusing. Move the NMI IRET fault processing to a new function, vmx_complete_interrupts(), which is called on the vmexit path. Signed-off-by: NAvi Kivity <avi@qumranet.com>

As suggested by Avi, introduce accessors to read/write guest registers. This simplifies the ->cache_regs/->decache_regs interface, and improves register caching which is important for VMX, where the cost of vmcs_read/vmcs_write is significant.

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: http://bugzilla.kernel.org/show_bug.cgi?id=11580 https://bugzilla.redhat.com/show_bug.cgi?id=451188Signed-off-by: NBjorn Helgaas <bjorn.helgaas@hp.com> Acked-by: NRafael J.

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. Signed-off-by: NBjorn Helgaas <bjorn.helgaas@hp.com> Acked-by: NRafael J.

Once kernel configuration has CONFIG_HID turned on, let also all the specialized drivers for quirky devices to be built (unless CONFIG_EMBEDDED is specified), as usually users don't care that much which driver gives them the functionality, but when they want generic support, they probably want to have support for all the quirky devices as well.

由 Anssi Hannula 提交于
Commit 8006479c 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.
