* gpio: implement bus_setup_intr and bus_teardown_intrAhmad Khalifa2025-09-301-0/+4
| | | | | | | | | | | Implement bus_setup_intr and bus_teardown_intr as bus_generic_setup_intr and bus_generic_teardown_intr respectively for GPIO drivers that support interrupts. This allows children to setup interrupts. Reported by: Evgenii Ivanov <devivanov@proton.me> Reviewed by: imp MFC after: 1 day Differential Revision: https://reviews.freebsd.org/D52197
* gpio: remove gpiobus_attach_busAhmad Khalifa2025-08-131-1/+2
| | | | | | | | | | | | Since gpiobus_attach_bus can attach the gpiobus child along with its children in the same bus pass, the parent controller's reference to gpiobus might not be set by the time the children need it. Instead, drivers should use gpiobus_add_bus and explicitly call bus_attach_children.

* bus_generic_detach: Delete children after detaching themJohn Baldwin2025-01-021-2/+0
| | | | | | | | | | | | | | | | | This provides better semantics as a standalone DEVMETHOD for device_attach as bus drivers should remove child devices they created as part of detach cleanup. The implementation calls bus_detach_children() first to permit child devices an opportunity to veto the detach operation. If that succeeds, device_delete_children() is used to delete the child devices. This requires fixing various drivers that were deleting devices explicitly (via a device_t pointer cached in the softc) after calling bus_generic_detach to stop doing that and just rely on bus_generic_detach to remove child devices.

* Check for errors when detaching children first, not lastJohn Baldwin2024-11-059-9/+55
| | | | | | | | | | | | These detach routines in these drivers all ended with 'return (bus_generic_detach())' meaning that if any child device failed to detach, the parent driver was left in a mostly destroyed state, but still marked attached.

* uart(4): Honor hardware state of NS8250-class for tsw_busyMarius Strobl2024-01-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | In 9750d9e5, I brought the equivalent of the TS_BUSY flag back in a mostly hardware-agnostic way in order to fix tty_drain() and, thus, TIOCDRAIN for UARTs with TX FIFOs. This proved to be sufficient for fixing the regression reported. So in light of the release cycle of FreeBSD 10.3, I decided that this change was be good enough for the time being and opted to go with the smallest possible yet generic (for all UARTs driven by uart(4)) solution addressing the problem at hand. However, at least for the NS8250-class the above isn't a complete fix as these UARTs only trigger an interrupt when the TX FIFO became empty. At this point, there still can be an outstanding character left in the transmit shift register as indicated via the LSR. Thus, this change adds the 3rd (besides the tty(4) and generic uart(4) bits) part I had in my tree ever since, adding a uart_txbusy method to be queried in addition for tsw_busy and hooking it up as appropriate for the NS8250-class. As it turns out, the exact equivalent of this 3rd part later on was implemented for uftdi(4) in 9ad221a5. While at it, explain the rational behind the deliberately missing locking in uart_tty_busy() (also applying to the generic sc_txbusy testing already present).

* Avoid waiting on physical allocations that can't possibly be satisfiedJason A. Harmening2023-12-241-3/+6
| | | | | | | | | | | | | | | | | | | | | | | - Change vm_page_reclaim_contig[_domain] to return an errno instead of a boolean. 0 indicates a successful reclaim, ENOMEM indicates lack of available memory to reclaim, with any other error (currently only ERANGE) indicating that reclamation is impossible for the specified address range. Change all callers to only follow up with vm_page_wait* in the ENOMEM case. - Introduce vm_domainset_iter_ignore(), which marks the specified domain as unavailable for further use by the iterator. Use this function to ignore domains that can't possibly satisfy a physical allocation request. Since WAITOK allocations run the iterators repeatedly, this avoids the possibility of infinitely spinning in domain iteration if no available domain can satisfy the allocation request.
