| | | | | | | | | 64-bit DMA. Should reduce the pressure on DMA-reachable memory, which is important since there are still cases where the pagedaemon ends up being triggered continuously if we run out of DMA-reachable memory but have plenty of memory left. ok jsg@

| | | | | | | in_irq() uses ci_idepth on archs that have it in_interrupt() is the same as in_irq() for now, linux has in_irq() for hard interrupt context and in_interrupt() is also for soft interrupt and nmi context.

* Improve the interaction between efifb(4), inteldrm(4) and radeondrm(4)kettenis2019-05-047-33/+74
| | | | | | | | | | | | | | | | when we have a serial console by introducing the notion of a "primary" graphics device. The primary graphics device is the one set up and used by firmware (BIOS, UEFI). The goal is to make sure that wsdisplay0 and drm0 reliably attach to the primary graphics device such that X works out of the box even if you have multiple cards or if you are using a serial console. This also fixes the situation where inteldrm(4) or radeondrm(4) would take over the console on UEFI systems even if the kernel was booted with a serial console. ok jsg@

* Since we now have an attachhook, the actual interrupt handler is installedkettenis2019-04-251-1/+4
| | | | | | | | | | late, after we enable interrupts. If the interrupt pin used for inteldrm(4) is shared with another device, we may end up being called before the actual interrup handler is installed resulting in a null-pointer dereference. Fix this by adding an explicit check that the interrupt handler function pointer has been set. ok matthieu@, jsg@
* Remove file name and line number output from witness(4)visa2019-04-233-51/+33
| | | | | | | | | | | | | Reduce code clutter by removing the file name and line number output from witness(4). Typically it is easy enough to locate offending locks using the stack traces that are shown in lock order conflict reports. Tricky cases can be tracked using sysctl kern.witness.locktrace=1 . This patch additionally removes the witness(4) wrapper for mutexes. Now each mutex implementation has to invoke the WITNESS_*() macros in order to utilize the checker.
