| | | | | | | | | | | | | | While a given ACPI device may have 0-N compatibility IDs, in practice most seem to have 0 or 1. If one is present, emit it as part of the PNP info string associated with a device. This could enable MODULE_PNP_INFO-based automatic kldload for ACPI drivers associated with a given _CID (but without a good _HID or _UID identifier).

Also avoid races by copying in the request structure to a temporary buffer before locking and modifying the device softc.

* Update owc_gpiobus (one-wire over gpio) to the modern gpio_pin interface.Ian Lepore2019-12-171-105/+88
| | | | | | | | | | | | | | | | | | It used to be required that a device be a child of gpiobus(4) to manipulate gpio pins. That requirement didn't work well for FDT-based systems with many cross-hierarchy users of gpio, so a more modern framework was created that removed the old hierarchy requirement. These changes adapt the owc_gpiobus driver to use the newer gpio_pin_* functions to acquire, release, and manipulate gpio pins. This allows a single driver to work for both hinted-attachment and fdt-based systems, and removes the requirement that any one-wire fdt nodes must appear at the root of the devicetree.

* kbd drivers: don't double register keyboard driversKyle Evans2019-12-166-0/+28
| | | | | | | | | | | | | | | | | | Keyboard drivers are generally registered via linker set. In these cases, they're also available as kmods which use KPI for registering/unregistering keyboard drivers outside of the linker set. For built-in modules, we still fire off MOD_LOAD and maybe even MOD_UNLOAD if an error occurs, leading to registration via linker set and at MOD_LOAD time. This is a minor optimization at best, but it keeps the internal kbd driver tidy as a future change will merge the linker set driver list into its internal keyboard_drivers list via SYSINIT and simplify driver lookup by removing the need to consult the linker set. Notes: svn path=/head/; revision=355806
* kbd: patch linker set methods, tooKyle Evans2019-12-161-0/+17
| | | | | | | | | | This is needed after r355796. Some double-registration of kbd drivers needs to be sorted out, then this sysinit will simply add these drivers into the normal list and kill off any other bits in the driver that are aware of the linker set, for simplicity. Notes: svn path=/head/; revision=355799
* kbd: remove kbdsw, store pointer to driver in each keyboard_tKyle Evans2019-12-162-92/+77
| | | | | | | | | | | | | | | | | | The previous implementation relied on a kbdsw array that mirrored the global keyboards array. This is fine, but also requires extra locking consideration when accessing to ensure that it's not being resized as new keyboards are added. The extra pointer costs little in a struct that there are relatively few of on any given system, and simplifies locking requirements ever-so-slightly as we only need to consider the locking requirements of whichever method is being invoked. __FreeBSD_version is bumped as any kbd modules will need rebuilt following this change.

* kbd: provide default implementations of get_fkeystr/diagKyle Evans2019-12-1610-20/+9

* kbd drivers: use kbdd_* indirection for diag invocationKyle Evans2019-12-163-3/+3
| | | | | | | | | | | These invocations were directly calling enkbd_diag(), rather than indirection back through kbdd_diag/kbdsw. While they're functionally equivent, invoking kbdd_diag where feasible (i.e. not in a diag implementation) makes it easier to visually identify locking needs in these other drivers.

* schedlock 4/4Jeff Roberson2019-12-152-4/+2
| | | | | | | | | | | | | | | | | | | | | Don't hold the scheduler lock while doing context switches. Instead we unlock after selecting the new thread and switch within a spinlock section leaving interrupts and preemption disabled to prevent local concurrency. This means that mi_switch() is entered with the thread locked but returns without. This dramatically simplifies scheduler locking because we will not hold the schedlock while spinning on blocked lock in switch. This change has not been made to 4BSD but in principle it would be more straightforward.

* Add a deferred free mechanism for freeing swap space that does not requireJeff Roberson2019-12-151-8/+2
| | | | | | | | | | | | | | | | | | | | | | an exclusive object lock. Previously swap space was freed on a best effort basis when a page that had valid swap was dirtied, thus invalidating the swap copy. This may be done inconsistently and requires the object lock which is not always convenient. Instead, track when swap space is present. The first dirty is responsible for deleting space or setting PGA_SWAP_FREE which will trigger background scans to free the swap space. Simplify the locking in vm_fault_dirty() now that we can reliably identify the first dirty.

Add a function that will detect if the card is present or not and that will attach/detach the mmc device. The function is either call on attach (as we won't have the interrupt fired) or from two taskqueues. The first taskqueue will directly call the function when the sdcard was present and is now removed and the other one will delay a bit the attach when we didn't had a card and now have one.
