The 64bit SMP bootup is slightly different to the 32bit one. It enables the boot CPU local APIC timer before all CPUs are brought up. Some AMD C1E systems have the C1E feature flag only set in the secondary CPU. Due to the early enable of the boot CPU local APIC timer the APIC timer is registered as a fully functional device. When we detect the wreckage during the bringup of the secondary CPU, we need to force the boot CPU into broadcast mode. Check the C1E caused APIC timer disable, when the secondary APIC timer is initialized. If the boot CPU APIC timer was registered as a functional clock event device, then fix this up and utilize the CLOCK_EVT_NOTIFY_BROADCAST_FORCE mechanism to force the already registered boot CPU APIC timer into broadcast mode. Tested by force injecting the failure mode. Signed-off-by: NThomas Gleixner <tglx@linutronix.de>

All the users go through virt_irq_to_bucket() and essentially want to go from a virt_irq to an INO, but we have a way to do that already via virt_to_real_irq_table[].dev_ino. This also allows us to kill both virt_to_real_irq() and virt_irq_to_bucket(). Signed-off-by: NDavid S. Miller <davem@davemloft.net>

We were simply concatenating the devhandle and devino and using that as the cookie, which defeats the entire purpose of the VIRQ hypervisor interfaces. Now that we use physical addresses for the INO buckets, we can allocate them dynamically for VIRQs and encode the cookies as ~__pa(bucket). This allows us to test for and decode the cookie with a simple: brlz $reg1, 1f xnor $reg1, %g0, $reg2 sequence. This works because bit 64 is never set in traditional INO vectors, and it is also never set in a physical address. So xnor'ing the physical address of the bucket always gives us a negative number, and thus a unique condition we can test cheaply. Inspired by ideas from Greg Onufer. Signed-off-by: NDavid S.

Currently we chain IVEC entries using 32-bit "pointers" because we know that the ivector_table is in the main kernel image, thus below 4GB. This uses proper 64-bit pointers instead. Whilst this bloats up the kernel image size, this sets the infrastructure necessary to significantly shrink the kernel size by using physical addresses and dynamically allocating the ivector table.

This also makes us use the MSI queues correctly. Each MSI queue is serviced by a normal sun4u/sun4v INO interrupt handler. This handler runs the MSI queue and dispatches the virtual interrupts indicated by arriving MSIs in that MSI queue. All of the common logic is placed in pci_msi.c, with callbacks to handle the PCI controller specific aspects of the operations. This common infrastructure will make it much easier to add MSG support.

Thanks to Tom Callaway for the excellent bug report and test case. sys_ipc() has several problems, most to due with semaphore call handling: 1) 'err' return should be a 'long' 2) "union semun" is passed in a register on 64-bit compared to 32-bit which provides it on the stack and therefore by reference 3) Second and third arguments to SEMCTL are swapped compared to 32-bit.

Added asm-sparc/irqflags.h and moved irq related code from system.h to it. Renamed local_irq functions to raw_local_irq in irq.c. Modified system.h to include linux/irqflags.h which includes asm/irqflags.h. Added TRACE_IRQFLAGS_SUPPORT to Kconfig.debug. This is the first step in adding IRQ-flags state tracing as outlined in Documentation/irqflags-tracing.txt. These changes should be harmless because they just move things around and rename them. The next step is making the lowlevel entry code modifications which to be honest are beyond my capabilities at this point. Boot tested on an ss20 running an SMP kernel.

movnt* instructions are not strongly ordered with respect to other stores, so if we are to assume stores are strongly ordered in the rest of the 64 bit code, we must fence these off (see similar examples in 32 bit code).

Use _CRS for PCI resource allocation This patch resolves an issue where incorrect PCI memory and i/o ranges are being assigned to hotplugged PCI devices on some IBM systems. The resource mis-allocation not only makes the PCI device unuseable but often makes the entire system unuseable due to resulting machine checks. The hotplug capable PCI slots on the affected systems are not located under a standard P2P bridge but are instead located under PCI root bridges or subtractive decode P2P bridges. For example, the IBM x3850 contains 2 hotplug capable PCI-X slots and 4 hotplug capable PCIe slots with the PCI-X slots each located under a PCI root bridge and the PCIe slots each located under a subtractive decode P2P bridge. The current i386/x86_64 PCI resource allocation code does not use _CRS returned resource information. No other resource information source is available for slots that are not below a standard P2P bridge so incorrect ranges are being allocated from e820 hole causing the bad result. This patch causes the kernel to use _CRS returned resource info. It is roughly based on a change provided by Matthew Wilcox for the ia64 kernel in 2005. Due to possible buggy BIOS factor and possible yet to be discovered kernel issues the function is disabled by default and can be enabled with pci=use_crs.
