2009-06-12lguest: optimize by coding restore_flags and irq_enable in assembler.Rusty Russell
The downside of the last patch which made restore_flags and irq_enable check interrupts is that they are now too big to be patched directly into the callsites, so the C versions are always used. But the C versions go via PV_CALLEE_SAVE_REGS_THUNK which saves all the registers. In fact, we don't need any registers in the fast path, so we can do better than this if we actually code them in assembler. The results are in the noise, but since it's about the same amount of code, it's worth applying. 1GB Guest->Host: input(suppressed),output(suppressed) Before: Seconds: 0:16.53 Packets: 377268,753673 Interrupts: 22461,24297 Notifications: 1(5245),21303(732370) Net IRQs triggered: 377023(245),42578(711095) After: Seconds: 0:16.48 Packets: 377289,753673 Interrupts: 22281,24465 Notifications: 1(5245),21296(732377) Net IRQs triggered: 377060(229),42564(711109) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-06-12lguest: improve interrupt handling, speed up stream networkingRusty Russell
lguest never checked for pending interrupts when enabling interrupts, and things still worked. However, it makes a significant difference to TCP performance, so it's time we fixed it by introducing a pending_irq flag and checking it on irq_restore and irq_enable. These two routines are now too big to patch into the 8/10 bytes patch space, so we drop that code. Note: The high latency on interrupt delivery had a very curious effect: once everything else was optimized, networking without GSO was faster than networking with GSO, since more interrupts were sent and hence a greater chance of one getting through to the Guest! Note2: (Almost) Closing the same loophole for iret doesn't have any measurable effect, so I'm leaving that patch for the moment.

2009-06-12module: trim exception table on init free.Rusty Russell
It's theoretically possible that there are exception table entries which point into the (freed) init text of modules. These could cause future problems if other modules get loaded into that memory and cause an exception as we'd see the wrong fixup. The only case I know of is kvm-intel.ko (when CONFIG_CC_OPTIMIZE_FOR_SIZE=n). Amerigo fixed this long-standing FIXME in the x86 version, but this patch is more general. This implements trim_init_extable(); most archs are simple since they use the standard lib/extable.c sort code. Alpha and IA64 use relative addresses in their fixups, so thier trimming is a slight variation. Sparc32 is unique; it doesn't seem to define ARCH_HAS_SORT_EXTABLE, yet it defines its own sort_extable() which overrides the one in lib. It doesn't sort, so we have to mark deleted entries instead of actually trimming them.

The sparseirq changes (d7e51e66) played poorly with the Blackfin irqchip implementation as we're still using the old hardirq method.

2009-06-12Blackfin: push access_ok() L1 attribute downMike Frysinger
There is no need for the L1 attribute to be on the prototype of the access_ok() function as all consumers of the function do not care where it lives -- they'll always use pcrel calls to get to it.

2009-06-12Blackfin: override default uClinux MTD addr/sizeMike Frysinger
Due to a processor anomaly (05000263 to be exact), most Blackfin parts cannot keep the embedded filesystem image directly after the kernel in RAM. Instead, the filesystem needs to be relocated to the end of memory. As such, we need to tweak the map addr/size during boot for Blackfin systems. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-06-12Blackfin: make deferred hardware errors more exactRobin Getz
Hardware errors on the Blackfin architecture are queued by nature of the hardware design. Things that could generate a hardware level queue up at the system interface and might not process until much later, at which point the system would send a notification back to the core. As such, it is possible for user space code to do something that would trigger a hardware error, but have it delay long enough for the process context to switch. So when the hardware error does signal, we mistakenly evaluate it as a different process or as kernel context and panic (erp!). This makes it pretty difficult to find the offending context. But wait, there is good news somewhere. By forcing a SSYNC in the interrupt entry, we force all pending queues at the system level to be processed and all hardware errors to be signaled. Then we check the current interrupt state to see if the hardware error is now signaled. If so, we re-queue the current interrupt and return thus allowing the higher priority hardware error interrupt to process properly. Since we haven't done any other context processing yet, the right context will be selected and killed. There is still the possibility that the exact offending instruction will be unknown, but at least we'll have a much better idea of where to look. The downside of course is that this causes system-wide syncs at every interrupt point which results in significant performance degradation. Since this situation should not occur in any properly configured system (as hardware errors are triggered by things like bad pointers), make it a debug configuration option and disable it by default.
