* [Mini-OS] Make bind_virq return the portKeir Fraser2007-11-231-1/+1
| | | | | | | Make bind_virq() return the port bound to the irq, which is useful e.g. for masking/unmasking it. Signed-off-by: Samuel Thibault <samuel.thibault@citrix.com>
* [Mini-OS] Fix x86 arch_switch_threadKeir Fraser2007-11-232-0/+38
| | | | | | | | | Fix x86 arch_switch_thread by making it pure assembly. There were missing general register clobbers for x86_64, and BP should theorically be clobbered too, but gcc does not believe that, so the only simple safe solution is to use pure assembly.

* [Mini-OS] Fix stack closuresKeir Fraser2007-11-232-0/+5
| | | | | | | | So as to make backtracing tools happy, correctly close x86 stacks for new threads as well as on callback in the x86_32 case since there is no unwind marker. Signed-off-by: Samuel Thibault <samuel.thibault@citrix.com>
* [Mini-OS] Fix x86 initial stack alignmentKeir Fraser2007-11-233-4/+6
| | | | | | | | | This fixes the initial stack alignment for x86, which is required for current to return a fine NULL instead of a random value or possibly crash during initialization. Signed-off-by: Grzegorz Milos <gm281@cam.ac.uk> Signed-off-by: Samuel Thibault <samuel.thibault@citrix.com>
