this fixes PCI interrupts on some systems (eg. HP XW9400) and we suspect that
the problems which led to the original change were caused by buggy early
implementations of ACPI, which are now ignored by date.
In ehci_get_ownership(), don't explicitly clear EHCI_LEG_HC_BIOS_OWNED
semaphore bit in the driver before asking BIOS to give up ownership.
The EHCI spec implies that the semaphore should not be changed by
the other agent and actually the previous one (introduced in rev 1.53
after 5.x) caused hangup during probe on at least two HP machines
as mentioned in the PR. Analyzed and patch provided by Ryo ONODERA.
Should be pulled up to netbsd-6 (fatal hangup during boot).
but add a second argument to it to indicate whether the TLB/caches need to be
flushed. Default cortex to pmap_needs_fixup = 1. But check the MMFR3 field
to see if the fixed can be skipped.
Use a cf_flag bit 0 to indicate whether the A9 L2 cache should disable (bit 0 = 1)
or enabeld (bit = 0).
With these changes, the A9 MMU can use traverse caches to do MMU tablewalks
Also, make sure all memory has the shareable bit for the A9.
- Change the synching order of descriptors. First, sync descriptors except
first and then sync the first descriptor.
- To recover from an race condition, reduce the if_timer from 5 to 1 and
when timeout occur write MVGBE_TQC_ENQ bit again.
been lightly tested with unmodified networking applications with both
the client and server on a 64bit le host. Unlike the standard Linux
compat libs where args and syscalls are swizzled around, this compat
lib only massages the arg data types due to the assumption that syscall
numbers come from librumpclient (via librumphijack) and therefore match
the native NetBSD numbers.
to the controller. This is compatible with the linux and FreeBSD
implementations.
Add the needed conversion for mfi ioctls in COMPAT_LINUX
Allocate a character major number, and create /dev/mfi0 by default
on amd64 and i386.
This allows (along with a hand-created /emul/linux/proc/devices file)
to run the MegaCLI linux binary provided by LSI.
