* Adapt radeondrm_detach_kms() to struct drm_device being split fromjsg2019-04-201-1/+1
| | | | | | | drm softc. Avoids uvm_fault() when firmware is missing and radeondrm is forcibly detached. Reported by Mihai Popescu on misc@

* i2c reads are more reliable a byte at a time.dlg2019-04-161-13/+13
| | | | | | reading all 256 at a time was a nice idea, but meant page 0xa2 wasnt appearing like it should. this follows what freebsd does more closely too.
* make sff page reads work on little endian archs too. like amd64.dlg2019-04-161-7/+7
| | | | | | some modules seem to need more time when waiting for bytes while here. hrvoje popovski hit the endian issue

| | | | | | conditional timeout_barrier(9). OK kn@ dlg@
* implement SIOCGIFSFFPAGE so ifconfig can get transceiver info.dlg2019-04-151-6/+81
| | | | | | | | myx doesn't allow i2c writes, so you can only read whatever page the firmware is already pointing at on device 0xa0. if you try to read another page it will return ENXIO. tested on a 10G-PCIE-8A-R with an xfp module.

| | | | | | | | the list of commands is going to grow, but the thought of keeping the list in debug code up to date with it just makes me feel tired. this prints the command id number instead in the same format we represent it in the header.
* Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 tojsg2019-04-14654-86315/+167959
| | | | | | | | | | | | | | | | | | | 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.

* implement support for SIOCGIFSFFPAGEdlg2019-04-101-1/+142
| | | | | | | | | | | | | | | | | | this relies on some firmware commands for accessing the i2c bus that are not available until a relatively recent API version. our nics using API 1.4 and 1.5 don't handle the command, but the API 1.7 nic we have is happy to talk to the module that is plugged into it. xl710 cards (the 40g ones with a qsfp+ connector) can be split up into 4 functions that represent lanes on a single port. you can get qsfp+ to 4x sfp+ cables so you can use the different lanes/functions as completely independent interfaces. however, because each lane/ function is one port and therefore module, we need to serialise access to the module by at least the port. this is to prevent concurrent reads of different pages of the one module from stepping on each other. i took the easy path and made a single ixlsff lock, which is at least conservative.
* add support for SIOCGIFSFFPAGE so userland can read sfp module infodlg2019-04-103-3/+64
| | | | | | | | | access to the ioctl is serialised by a per ifp rwlock so userland reads of different pages in the same device address do not confuse each other. this was pretty straightforward because a lot of the plumbing for accessing the i2c bus was already in place.
* Handle missed service errors, specific to isochronous transfers.ratchov2019-04-101-1/+52
| | | | | | | | | After each MSE, ensuire usbd_complete_transfer() is called for each missed transfer, for which there's no transfer completion event. Fixes crashes and deadlocks in upper layers caused by the missing completion. ok deraadt, patrick; help from mpi, patrick, gmlocker
* Fix URE_WDT6_SET_MODE register definition.kevlo2019-04-101-2/+2

* Try to start playback after play buffer pointers are advanced.ratchov2019-04-051-4/+6
| | | | | | Allows playback to start automatically as soon as there's enough data, even if the AUDIO_START ioctl is not called. This is mainly useful to quickly test & debug low level drivers with simple shell commands.
* Make tpm(4) attach to MSFT0101 chips.edd2019-04-041-1/+2
| | | | | | | I found this chip in my Lenovo Thinkpad X1 (5th gen): tpm0 at acpi0: TPM_ addr 0xfed40000/0x5000: device 0x001b15d1 rev 0x10 "Yes, please commit this" deraadt@. Thanks.
* Simplify underruns handling: just copy silence produced by upper layer.ratchov2019-04-041-30/+7
| | | | | This makes the code less bug prone as the "rare" underruns conditions are handled by the main non-underrun code.

* Always copy data (if any) whenever a new bounce buffer is available.ratchov2019-04-031-1/+2
|
* Check for available space before copying data to the bounce buffers.ratchov2019-04-031-12/+6
| | | | | No behavior change as we don't call uaudio_pdata_copy() in situations when bounce buffers may not be available.
* Make the uaudio_stream->ubuf_xfer relative to current xfer number.ratchov2019-04-031-9/+35
| | | | | No behavior change. The new representation is equivalent but eases detection of overflows and underflows.

* Enable RF_KILL interrupts on resumekn2019-04-011-1/+4
| | | | | | | | | | | | | Like the interrupt handler, the resume path needs to check the register to update flags in order to propagate the hardware kill switch state, otherwise the driver would still consider the switch to be off after resume even though it may have changed while in S3. Fix the resume path by simply applying the same idiom already found in iwm_start_hw(). This will ensure seemless operation no matter which combination of switch toggling and suspend/resume users will follow. OK stsp
* Fix interrupt handler to set RUNNING flag when RF switch is enabledkn2019-04-011-6/+5
| | | | | | | | | | | | | | | | | | With an UP and RUNNING interface, turning off the hardware kill switch removes the RUNNING flag and powers down the device. Iff still UP, switching it back would not reset the flag accordingly. Fix this in analogy to sys/dev/pci/if_iwn.c revision 1.204 by scheduling iwm_init() unconditionally on both hardware kill switch edges; it'll take care of everything else. Tested with iwm0 at pci2 dev 0 function 0 "Intel Dual Band Wireless AC 7260" rev 0xbb, msi iwm0: hw rev 0x140, fw ver 16.242414.0 OK deraadt stsp
