* Let drm(4) allocate memory without constraints if the hardware supportskettenis2019-06-091-12/+13
| | | | | | | | | 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@
* Move a function used as a callback out of a header so there will only bejsg2019-06-041-60/+2

* add amdgpu from linux 4.19.44 for recent AMD Radeon partsjsg2019-05-211-0/+2
| | | | | | | committing now so this can be worked on in tree Thanks to the OpenBSD Foundation for sponsoring this work and kettenis@ for helping.
* add in_irq() in_interrupt() in_task()jsg2019-05-131-0/+14
| | | | | | | 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)kettenis2019-05-041-6/+5
| | | | | | | | | | | | | | | | 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@
* Avoid using an expression which resolves to an int in a bool contextjsg2019-05-011-2/+2
| | | | | when a nested macro is called with an expression argument. Prompted by -Wint-in-bool-context with gcc 8. ok kettenis@
* 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. Discussed with and OK dlg@, OK mpi@

* Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 tojsg2019-04-14270-0/+35385
linux 4.19.34. Adds support for more Intel hardware: Broxton/Apollo Lake (was is_preliminary in 4.4) Amber Lake (another Kaby Lake refresh) Gemini Lake Coffee Lake Whiskey Lake Cannon Lake (though no hardware with Intel graphics ever shipped) Ice Lake (alpha support, hardware not released) This does not add support for new radeon hardware on the AMD side as newer radeons have a different kernel driver (amdgpu). Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for helping and a bunch of other developers for testing.
