potential crash. This must have somehow been working by magic. Fruther cleanup of QoS support in this driver is very much needed. ok mpi@

2015-10-06Make sure that tx_buffer->next_eop is properly set before we bump the numberkettenis1-7/+13
of available descriptors, such that the interrupt handler doesn't attempt to complete partially initialized descriptors. Seems to fix the watchdog timeouts reported by various people. Tested by Mattieu Baptiste and Gregor Best. ok mikeb@

ok mpi@
2015-10-05Simplify iwm(4) newstate task by only queuing one state transitionstsp2-53/+26
at a time. The newstate task now always transitions to the most recently requested state, rather than hopping along with every request. This allows us get rid of the silly newstate generation counter, and we can now task_del() a pending transition when the interface goes down. While several issues with this driver remain, I believe this change does not introduce new problems. Tested by myself, jasper@, and zhuk@

2015-09-30Run the tx completion path without the kernel held. This makes thekettenis2-47/+29
"fast path" through the interrupt handler not grab the kernel lock anymore. This removes the code that attempts to reclaim tx descriptors from em_start(). Keeping that code would have complicated the locking. The need to reclaim tx descriptors that way should have largely disappeared now that the interrupt handler doesn't have to wait on the kernel lock. ok mpi@ tested by many
2015-09-30I missed an #ifdef notyet when enabling the aliasing ppgtt code.kettenis1-3/+1
Hopefully this fixes the stability problems people have been seeing on sandybridge and up after the ppgtt code got enabled.

ok mikeb@
2015-09-29get rid of the mutex between access to the status block and myx_downdlg1-65/+44
myx is unusual in that it has an explicit command to shut down the chip that gets an interrupt when it's done. so myx_down sends the command and has to sleep until it gets that interrupt. this moves to using a single int to represent that state (so loads and stores are atomic), and sleep_setup/sleep_finish in myx_down to wait for it to change. this has been running in production at work for a few months now tested by chris@

2015-09-28In low-level suspend routines, set cold=2. In tsleep(), use this toderaadt1-2/+2
spit out a ddb trace to console. This should allow us to find suspend or resume routines which break the rules. It depends on the console output function being non-sleeping.... but that's another codepath which should try to be safe when cold is set. ok kettenis
2015-09-28The Linux code that handles the DPMS mode for inteldrm(4) can sleep now.kettenis2-8/+26
Adopt the approach taken by radeondrm(4) and hand the "burner" work off to a task. Avoids the panic reported by Gerald Hanuer, who also tested this fix.
2015-09-28remove duplicate entry caused by the "Quanta Transcode" devicejsg1-1/+0
2015-09-28Remove the "Quanta Transcode" device from the list of supported hardware.kettenis1-12/+1
It's only supposed to match certain subvendor/subdevice IDs, but our code doesn't check those. The result is that it (incorrectly) overrides the generic match for the HD Graphics P4000 as found on some Xeon E3 CPUs. This device is supposedly a castrated version of that device with the display output parts fused off. According to the original Linux commit it is "some HW being used for a demo", and there have been proposals to remove it from the Linux tree as well. It is unlikely that OpenBSD will ever run on this particular hardware.
2015-09-27Enable monitor hot plugging for the framebuffer console.kettenis4-37/+25
Tested on the VGA port of a Radeon 7500 and Radeon 9250 (aka 9200 PRO). Hopefully this works on Intel Graphics as well.
2015-09-27Fix bsd.rd upgrades over iwm(4), and fix `ifconfig iwm0 lladdr random`.stsp1-6/+18
The bsd.rd problems happened because of the net80211 detach/attach hack which ran when the firmware is loaded for the first time. Do the minimum of what needs to be done instead. To fix lladdr random pick up a changing MAC address in the ioctl handler and don't overwrite a custom MAC address while loading the firmware. ok kettenis@

2015-09-26Try a little bit harder to clean up if attaching inteldrm(4) fails.kettenis3-50/+87
The crucial bit is that we now clear dev->dev_priv, which prevents the X server from opening /dev/drmN and crashing the kernel because the driver isn't fully initialized. While there, try a little bit harder to print error messages the proper way. Things will still look ugly though if the failure is somewhere in the Linux code.
2015-09-26Update drm_irq.c to the version from Linux 3.14.52.kettenis9-362/+451
Disable the DRM_IOCTL_IRQ_BUSID and DRM_IOCTL_CONTROL ioctls. These are legacy ioctls for DRI1 support, which we no longer support on OpenBSD.

2015-09-26Make the PPGTT code work. Seems to fix the caching issues on Broadwell.kettenis4-16/+151
Comments on some of the later Broadwell-related commits in the Linux tree seem to say that the PPAT flags in for the (global) GTT are simply broken in the hardware.
