9820da104d Don't abuse config_interrupts()'s first argument. Use kthread instead of 
config_interrupt(). OK'd by jmcneill and macallan.

ca99157187 ena(4): Add support for Amazon.com Elastic Network Adapter (ENA). 
Many people contributed to this so I set the developer to "netbsd", please
change if there is a better way to do this.

d02195817d It is not only the EXIT trap we need to check for when deciding no

01089dfb82 allow MSI-X if supported by the hardware, discussed with Manuel 2018-11-30 17:53:08 +00:00

7181fba082 simplify intr establish code - rely on pci_intr_alloc() to return 
interrupt types which are possible for pci_intr_establish(); remove
fallbacks to retry with MSI explicitly disabled

bge(4) specifically needs to disable MSI on some boards which are
known to have broken MSI support, so this can't use pci_intr_alloc()
with just NULL counts

discussed on tech-kern@, and specifically bge(4) with Manuel

also MSI-X, and to return interrupt types which are possible for
pci_intr_establish(); remove fallbacks to retry with MSI/MSI-X
explicitly disabled

b2711c17ca The SHOULDYIELD flag doesn't indicate that other LWPs could run but only 
that the current LWP was seen on two consecutive scheduler intervals.

There are currently at least 3 cases for calling preempt().
- always call preempt()
- check the SHOULDYIELD flag
- check the real ci_want_resched

So the forced check for SHOULDYIELD changed the scheduler timing. Revert
it for now.

02397a5780 Zfs_write() may hide write errors if uiomove() succeeds but a 
further dmu_tx_assign() fails because over quota or no space.

Use the emulated uiocopy() and uioskip() like illumos does.

Fix the uiocopy() emulation to not clobber the iovecs.

55fedabe00 The downstream port of PCIe switch is not a root port, so don't print 
root port related register. For example, Intel 63xxESB controller's
downstream port device was printed by pcictl(8) with this bug:
