| * OMAP: Add support for VRFB rotation engineTomi Valkeinen2009-12-093-0/+319
| | | | | | | | | | | | | | | | | | | | | | | | VRFB rotation engine is a block in OMAP2/3 that offers 12 independent contexts that can be used for framebuffer rotation. Each context has a backend area of real memory, where it stores the pixels in undisclosed format. This memory is offered to users via 4 virtual memory areas, which see the same memory area in different rotation angles (0, 90, 180 and 270 degrees).

| * OMAP: Add VRAM managerTomi Valkeinen2009-12-095-0/+660
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a Video RAM manager for OMAP 2 and 3 platforms. VRAM manager is used to allocate large continuous blocks of SDRAM or SRAM. The features VRAM manager has that are missing from dma_alloc_* functions are: - Support for OMAP2's SRAM - Allocate without ioremapping - Allocate at defined physical addresses - Allows larger VRAM area and larger allocations The upcoming DSS2 uses VRAM manager. VRAM area size can be defined in kernel config, board file or with kernel boot parameters. Board file definition overrides kernel config, and boot parameter overrides kernel config and board file.

| | | | | | | | | | | | | | | | | | | | | | | | The upcoming new display subsystem driver is divided to two devices, omapdss and omapfb, of which omapdss handles the actual hardware. This patch adds a dummy omapdss platform device for the current omapfb driver, which is then used to get the clocks. This will make it possible for the current and the new display drivers to co-exist. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com> Acked-by: Tony Lindgren <tony@atomide.com>

| * | xen: try harder to balloon up under memory pressure.Ian Campbell2009-12-041-26/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently if the balloon driver is unable to increase the guest's reservation it assumes the failure was due to reaching its full allocation, gives up on the ballooning operation and records the limit it reached as the "hard limit". The driver will not try again until the target is set again (even to the same value). However it is possible that ballooning has in fact failed due to memory pressure in the host and therefore it is desirable to keep attempting to reach the target in case memory becomes available. The most likely scenario is that some guests are ballooning down while others are ballooning up and therefore there is temporary memory pressure while things stabilise. You would not expect a well behaved toolstack to ask a domain to balloon to more than its allocation nor would you expect it to deliberately over-commit memory by setting balloon targets which exceed the total host memory. This patch drops the concept of a hard limit and causes the balloon driver to retry increasing the reservation on a timer in the same manner as when decreasing the reservation. Also if we partially succeed in increasing the reservation (i.e. receive less pages than we asked for) then we may as well keep those pages rather than returning them to Xen.

| * | xen: explicitly create/destroy stop_machine workqueues outside ↵Ian Campbell2009-12-031-1/+11

I have observed cases where the implicit stop_machine_destroy() done by stop_machine() hangs while destroying the workqueues, specifically in kthread_stop(). This seems to be because timer ticks are not restarted until after stop_machine() returns. Fortunately stop_machine provides a facility to pre-create/post-destroy the workqueues so use this to ensure that workqueues are only destroyed after everything is really up and running again. I only actually observed this failure with 2.6.30. It seems that newer kernels are somehow more robust against doing kthread_stop() without timer interrupts (I tried some backports of some likely looking candidates but did not track down the commit which added this robustness). However this change seems like a reasonable belt&braces thing to do.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing error handling has a few issues: - If freeze_processes() fails it exits with shutting_down = SHUTDOWN_SUSPEND. - If dpm_suspend_noirq() fails it exits without resuming xenbus. - If stop_machine() fails it exits without resuming xenbus or calling dpm_resume_end(). - xs_suspend()/xs_resume() and dpm_suspend_noirq()/dpm_resume_noirq() were not nested in the obvious way. Fix by ensuring each failure case goto's the correct label. Treat a failure of stop_machine() as a cancelled suspend in order to follow the correct resume path.

| * | xen: don't leak IRQs over suspend/resume.Ian Campbell2009-12-031-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On resume irq_info[*].evtchn is reset to 0 since event channel mappings are not preserved over suspend/resume. The other contents of irq_info is preserved to allow rebind_evtchn_irq() to function. However when a device resumes it will try to unbind from the previous IRQ (e.g. blkfront goes blkfront_resume() -> blkif_free() -> unbind_from_irqhandler() -> unbind_from_irq()). This will fail due to the check for VALID_EVTCHN in unbind_from_irq() and the IRQ is leaked. The device will then continue to resume and allocate a new IRQ, eventually leading to find_unbound_irq() panic()ing. Fix this by changing unbind_from_irq() to handle teardown of interrupts which have type!=IRQT_UNBOUND but are not currently bound to a specific event channel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The logic of is_disconnected_device/exists_disconnected_device is wrong in that they are used to test whether a device is trying to connect (i.e. connecting). For this reason the patch fixes them to not consider a Closing or Closed device to be connecting. At the same time the patch also renames the functions according to what they really do; you could say a closed device is "disconnected" (the old name), but not "connecting" (the new name).

This is correct for memory backed by PCI devices, but wrong for memory allocated from System RAM where the PFN != MFN. During page faults, pages with VM_IO, get assigned to special domain I/O domain and as said, the PFN is interpreted as MFN. When Xen hypervisor modifies the PTE it interprets the PFN as the MFN, complains and fails the PTE modification. The end result is an infinitive page fault in the domain.

Changed to an info message because this condition is not actually an error. It is caused by the BIOS attempting to truncate the package on the fly by adjusting the package element count at the start of the package definition.
