* alc(4): disable MSI-X by default on Killer cardsLexi Winter2024-04-231-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | Several users with alc(4)-based "Killer" Ethernet cards have reported issues with this driver not passing traffic, which are solved by disabling MSI-X using the provided tunable. To work around this issue, disable MSI-X by default on this card. This is done by having msix_disable default to 2, which means "auto-detect". The user can still override this to either 0 or 1 as desired. Since these are slow (1Gbps) Ethernet ICs used in low-end systems, it's unlikely this will cause any practical performance issues; on the other hand, the card not working by default likely causes issues for many new FreeBSD users who find their network port doesn't work and have no idea why.

* wg: Add netmap supportMark Johnston2024-04-201-0/+14
| | | | | | | | | | | | | | | | | | | | | | | When in netmap (emulated) mode, wireguard interfaces prepend or strip a dummy ethernet header when interfacing with netmap. The netmap application thus sees unencrypted, de-encapsulated frames with a fixed header. In this mode, netmap hooks the if_input and if_transmit routines of the ifnet. Packets from the host TX ring are handled by wg_if_input(), which simply hands them to the netisr layer; packets which would otherwise be tunneled are intercepted in wg_output() and placed in the host RX ring. The "physical" TX ring is processed by wg_transmit(), which behaves identically to wg_output() when netmap is not enabled, and packets appear in the "physical" RX ring by hooking wg_deliver_in().

* sound: Implement asynchronous device detachChristos Margiolis2024-04-111-10/+1
| | | | | | | | | | | | | | | | | | | | | | | Hot-unplugging a sound device, such as a USB sound card, whilst being consumed by an application, results in an infinite loop until either the application closes the device's file descriptor, or the channel automatically times out after hw.snd.timeout seconds. In the case of a detach however, the timeout approach is still not ideal, since we want all resources to be released immediatelly, without waiting for N seconds until we can use the bus again. The timeout mechanism works by calling chn_sleep() in chn_read() and chn_write() (see pcm/channel.c) in order to send the thread to sleep, using cv_timedwait_sig(). Since chn_sleep() sets the CHN_F_SLEEPING flag while waiting for cv_timedwait_sig() to return, we can test this flag in pcm_unregister() (called during detach) and wakeup the sleeping thread(s) to immediately kill the channel(s) being consumed.

* sound: Get rid of snd_clone and use DEVFS_CDEVPRIV(9)Christos Margiolis2024-04-111-41/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the snd_clone framework creates device nodes on-demand for every channel, through the dsp_clone() callback, and is responsible for routing audio to the appropriate channel(s). This patch gets rid of the whole snd_clone framework (including any related sysctls) and instead uses DEVFS_CDEVPRIV(9) to handle device opening, channel allocation and audio routing. This results in a significant reduction in code size as well as complexity. Behavior that is preserved: - hw.snd.basename_clone. - Exclusive access of an audio device (i.e VCHANs disabled). - Multiple processes can read from/write to the device. - A device can only be opened as many times as the maximum allowed channel number (see SND_MAXHWCHAN in pcm/sound.h). - OSSv4 compatibility aliases are preserved. Behavior changes: Only one /dev/dspX device node is created (on attach) for each audio device, as opposed to the current /dev/dspX.Y devices created by snd_clone. According to the sound(4) man page, devices are not meant to be opened through /dev/dspX.Y anyway, so it is best if we do not create device nodes for them in the first place. As a result of this, modify dsp_oss_audioinfo() to print /dev/dspX in the "ai->devnode", instead of /dev/dspX.Y.

* periodic/daily/801.trim-zfs: Add a daily zfs trim scriptLexi Winter2024-04-091-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | As mentioned in zpoolprops(7), on some SSDs, it may not be desirable to use ZFS autotrim because a large number of trim requests can degrade disk performance; instead, the pool should be manually trimmed at regular intervals. Add a new daily periodic script for this purpose, 801.trim-zfs. If enabled (daily_trim_zfs_enable=YES; the default is NO), it will run a 'zpool trim' operation on all online pools, or on the pools listed in 'daily_trim_zfs_pools'. The trim is not started if the pool is degraded (which matches the behaviour of the existing 800.scrub-zfs script) or if a trim is already running on that pool. Having autotrim enabled does not inhibit the periodic trim; it's sometimes desirable to run periodic trims even with autotrim enabled, because autotrim can elide trims for very small regions.
