| * | | [PARISC] Fix show_stack() when we can't kmallocMatthew Wilcox2007-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | show_stack() was calling kzalloc() to allocate a struct pt_regs. This meant that *really* early stack dumps would cause a null pointer dereference. x86_64 allocates its pt_regs on the stack, so do the same. Kyle actually committed this exact patch to CVS on Wed Jul 26 14:32:39 2006 UTC, and never moved it across to git. Bad Kyle.

This extension is currently implemented by 4KS[CD] CPUs. Basically it saves/restores ACX register, which is part of the SMARTMIPS ASE, when needed. This patch does *not* add any support for Smartmips MMU features. Futhermore this patch does not add explicit support for 4KS[CD] CPUs since they are respectively mips32 and mips32r2 compliant. So with the current processor configuration, a platform that has such CPUs needs to select both configs: CPU_HAS_SMARTMIPS SYS_HAS_CPU_MIPS32_R[12] This is due to the processor configuration which is mixing up all the architecture variants and the processor types. The drawback of this, is that we currently pass '-march=mips32' option to gcc when building a kernel instead of '-march=4ksc' for 4KSC case. This can lead to a kernel image a little bit bigger than required. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* | | | | | [PATCH] x86_64 irq: Safely cleanup an irq after moving it.Eric W. Biederman2007-02-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem: After moving an interrupt when is it safe to teardown the data structures for receiving the interrupt at the old location? With a normal pci device it is possible to issue a read to a device to flush all posted writes. This does not work for the oldest ioapics because they are on a 3-wire apic bus which is a completely different data path. For some more modern ioapics when everything is using front side bus delivery you can flush interrupts by simply issuing a read to the ioapic. For other modern ioapics emperical testing has shown that this does not work. So it appears the only reliable way to know the last of the irqs from an ioapic have been received from before the ioapic was reprogrammed is to received the first irq from the ioapic from after it was reprogrammed. Once we know the last irq message has been received from an ioapic into a local apic we then need to know that irq message has been processed through the local apics. Signed-off-by: Eric W.

Which makes for a lot of arguments to pass/return and confusion as to what to do if you need the status but you aren't calling assign_irq_vector. This patch stops returning values from assign_irq_vector that can be retrieved just as easily by examining irq_cfg, and modifies the callers to retrive those values from irq_cfg when they need them.

The parallel arrays make the code harder to maintain and make it difficult to remove the static limits on the number of the number of irqs.
