| | | | | | | | | If an error occurs during attach after ofw_pcib_init() runs, the device is torn down, leaving the rmans embedded in the softc attached to the rman list, thus corrupting the rman list. Fix this by undoing everything that was done by this point. MFC after: 1 week

* 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.

| | | | | | | | | | | | 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. Instead, bus drivers should detach child drivers first and return errors before destroying driver state in the parent. Reviewed by: imp Differential Revision: https://reviews.freebsd.org/D47387

| | | | | | | | | | The CAM 'maxio' is a 'pessimized' size, assuming 4k pages and one page per segment.

* mpc85xx/pci: Conditionally reset PCI bridgesJustin Hibbits2022-07-301-12/+16
| | | | | | | | | Sometimes we need to reset a PCIe bus, but sometimes it breaks the downstream device(s). Since, from my testing, this is only needed for Radeon cards installed in the AmigaOne machines because the card was already initialized by firmware, make the reset dependent on a device hint (hint.pcib.X.reset=1). With this, AmigaOne X5000 machines can have other devices in the secondary PCIe slots.

* Make MAXPHYS tunable. Bump MAXPHYS to 1M.Konstantin Belousov2020-11-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace MAXPHYS by runtime variable maxphys. It is initialized from MAXPHYS by default, but can be also adjusted with the tunable kern.maxphys. Make b_pages[] array in struct buf flexible. Size b_pages[] for buffer cache buffers exactly to atop(maxbcachebuf) (currently it is sized to atop(MAXPHYS)), and b_pages[] for pbufs is sized to atop(maxphys) + 1. The +1 for pbufs allow several pbuf consumers, among them vmapbuf(), to use unaligned buffers still sized to maxphys, esp. when such buffers come from userspace (*). Overall, we save significant amount of otherwise wasted memory in b_pages[] for buffer cache buffers, while bumping MAXPHYS to desired high value. Eliminate all direct uses of the MAXPHYS constant in kernel and driver sources, except a place which initialize maxphys. Some random (and arguably weird) uses of MAXPHYS, e.g. in linuxolator, are converted straight. Some drivers, which use MAXPHYS to size embeded structures, get private MAXPHYS-like constant; their convertion is out of scope for this work.

There are 256 MSIs per MSI bank (32 per MSI IRQ, 8 IRQs per MSI bank). The P5020 has 3 banks, yielding up to 768 MSIs; older SoCs have only one bank. Notes: svn path=/head/; revision=354525

| | | | | | | | | | | | | | | | | | | | Summary: Due to bugs in the enumeration code, fsl_pcib_init() was not configuring sub-bridges properly, so devices hanging off a separate bridge would not be found. Since the generic PCI code already supports probing child buses, just delete this code and initialize only the device itself, letting the generic code handle all the additional probing and initializing. This also deletes setup for some PCI peripherals found on some MPC85XX evaluation boards. The code can be resurrected if needed, but overly complicated this code in the first place.
