Author: jhb Date: Thu Jun 25 18:13:46 2009 New Revision: 194985 URL: http://svn.freebsd.org/changeset/base/194985Log: - Restore the behavior of pre-allocating IDT vectors for MSI interrupts. This is mostly important for the multiple MSI message case where the IDT vectors for the entire group need to be allocated together. This also restores the assumptions made by the PCI bus code that it could invoke PCIB_MAP_MSI() once MSI vectors were allocated. - To avoid whiplash with CPU assignments, change the way that CPUs are assigned to interrupt sources on activation. Instead of assigning the CPU via pic_assign_cpu() before calling enable_intr(), allow the different interrupt source drivers to ask the MD interrupt code which CPU to use when they allocate an IDT vector. I/O APIC interrupt pins do this in their pic_enable_intr() routines giving the same behavior as before. MSI sources do it when the IDT vectors are allocated during msi_alloc() and msix_alloc(). - Change the intr_table_lock from an sx lock to a mutex.Tested by: rnoland
It seems also fixed previously not working multi-vector MSI mode of AHCI on my less lucky laptop. Thanks.
