2020-06-23add intrmap_one, some temp code to help us write pci_intr_establish_cpu.David Gwynne
it means we can do quick hacks to existing drivers to test interrupts on multiple cpus. emphasis on quick and hacks. ok jmatthew@, who will also ok the removal of it at the right time.
2020-06-23Implement pci_intr_establish_cpu() for pyro(4) and vpci(4) based sparc64Jonathan Matthew
systems. MSIs on these systems are delivered to event queues, which trigger interrupts when non-empty. The interrupt handler dequeues the MSIs and converts them into soft interrupts, which run on the same cpu as the event queue interrupt. To target pci device interrupts to different cpus, we set up an event queue per cpu in the system, or as many as we can, if there are fewer event queues available. For now, we don't have a way to feed this information back to intrmap, so instead we just map interrupts for cpus that don't have an event queue to another cpu that does have one. Tested on V215 (pyro), T5120, T4-1, S7-2 (vpci). dlg@ got the pyro side of it working for me. ok dlg@ kettenis@
2020-06-22timecounting: add gettime(9), getuptime(9)cheloha
time_second and time_uptime are used widely in the tree. This is a problem on 32-bit platforms because time_t is 64-bit, so there is a potential split-read whenever they are used at or below IPL_CLOCK. Here are two replacement interfaces: gettime(9) and getuptime(9). The "get" prefix signifies that they do not read the hardware timecounter, i.e. they are fast and low-res. The lack of a unit (e.g. micro, nano) signifies that they yield a plain time_t. As an optimization on LP64 platforms we can just return time_second or time_uptime, as a single read is atomic. On 32-bit platforms we need to do the lockless read loop and get the values from the timecounter. In a subsequent diff these will be substituted for time_second and time_uptime almost everywhere in the kernel. With input from visa@ and dlg@. ok kettenis@

2020-06-22inittodr(9): introduce dedicated flag to enable writes from resettodr(9)cheloha
We don't want resettodr(9) to write the RTC until inittodr(9) has actually run. Until inittodr(9) calls tc_setclock() the system UTC clock will contain a meaningless value and there's no sense in overwriting a good value with a value we know is nonsense. This is not an uncommon problem if you're debugging a problem in early boot, e.g. a panic that occurs prior to inittodr(9). Currently we use the following logic in resettodr(9) to inhibit writes: if (time_second == 1) return; ... this is too magical. A better way to accomplish the same thing is to introduce a dedicated flag set from inittodr(9). Hence, "inittodr_done". Suggested by visa@. ok kettenis@
2020-06-22Enable interrupts when they were enabled before the trap (except when weMark Kettenis
are handling "genuine" interrupts like the decrementer and hypervisor virtualization interrupts).

2020-06-22Make return-to-user and kernel re-entry work. This adds a per-pmap SLBMark Kettenis
cache. We might want to turn that in a per-proc cache at some point, but this gets us to the point where we can sucessfully have init(1) do its first system call.

2020-06-22Some connectors attach late when the drm driver is registers. ForMark Kettenis
that reason we have to delay attaching Backlight properties to those connectors until after drm driver registration. However the drm midlayer code now warns about attaching new properties to connectors after driver registration. So add some workarounds to suppress these warning messages.

This filter, already implemented in macOS and Dragonfly BSD, returns exceptional conditions like the reception of out-of-band data.

2020-06-22The interface if_ioctl routine must be called with the NET_LOCK() held.Claudio Jeker
For example the bridge_ioctl() function calls NET_UNLOCK() unconditionally and so calling if_ioctl() without netlock will trigger an assert because of not holding the netlock. Make sure the ioctl handlers are called with the netlock held and drop the lock for the wg(4) specific ioctls in the wg_ioctl handler. This fixes a panic in bridge_ioctl() triggered by ifconfig(8) issuing a SIOCGWG ioctl against bridge(4). This is just a workaround this needs more cleanup but at least this way the panic can not be triggered anymore. OK stsp@, tested by semarie@

2020-06-22Fix two iwx(4) TX_CMD_OFFLD macros.Stefan Sperling
The IP_HDR and MH_SIZE fields represent byte offsets into the frame, rather than flags. Make these macros require a parameter to prevent them from being misunderstood as flag bits. In iwlwifi these are defined via an enum, with most values being used as parameters to BIT(). Yet these IP and MH ones are actually used to shift length values to particular positions within the offloading parameters of the Tx command. Fortunately, these macros aren't used yet in our version of the driver.
2020-06-22Prepare for newer iwx(4) firmware scan command versions.Stefan Sperling
Add declarations of "version 2" scan flags from iwlwifi and prepare the iwx_scan_channel_cfg_umac struct for life beyond version 1. None of this is needed yet. But we will need this at some point and I've already written the diff, hoping it would prevent firmware errors (which of course it didn't).
2020-06-22Update definition of the iwx_ac_to_tx_fifo map.Stefan Sperling
Compared to iwm(4) devices the BE and BK fifo numbers have been swapped in iwx(4) hardware. This has no real consequences for us since we send all frames at the same access category, but I'm fixing the mapping anyway.
2020-06-22Enable critical temperature detection in iwx(4) firmware.Stefan Sperling
The driver will turn the device off and print a message to dmesg if the firmware signals critical temperature. It looks like the firmware will also make use of a Tx-backoff mechanism to regulate device temperature.
