* Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)Pawel Biernacki2020-02-261-1/+2
| | | | | | | | | | | | | | | | | | | r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags. Mark all obvious cases as MPSAFE. All entries that haven't been marked as MPSAFE before are by default marked as NEEDGIANT Approved by: kib (mentor, blanket) Commented by: kib, gallatin, melifaro Differential Revision: https://reviews.freebsd.org/D23718 Notes: svn path=/head/; revision=358333
* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255
* Fix device delete child function.Hans Petter Selasky2016-10-171-2/+1
| | | | | | | | | | | | | | | | | | | | | | | When detaching device trees parent devices must be detached prior to detaching its children. This is because parent devices can have pointers to the child devices in their softcs which are not invalidated by device_delete_child(). This can cause use after free issues and panic(). Device drivers implementing trees, must ensure its detach function detaches or deletes all its children before returning. While at it remove now redundant device_detach() calls before device_delete_child() and device_delete_children(), mostly in the USB controller drivers.

* Convert rman to use rman_res_t instead of u_longJustin Hibbits2016-01-271-4/+4
| | | | | | | | | | | | | | | | | | | | | | | Summary: Migrate to using the semi-opaque type rman_res_t to specify rman resources. For now, this is still compatible with u_long. This is step one in migrating rman to use uintmax_t for resources instead of u_long. Going forward, this could feasibly be used to specify architecture-specific definitions of resource ranges, rather than baking a specific integer type into the API. This change has been broken out to facilitate MFC'ing drivers back to 10 without breaking ABI.

| | | | | | | | | | | | | | | | | | The rewrite of the interrupt handler includes: o loop until all pending interrupts are handled. This closes a race condition. o count the number of interrupt sources we handled so that we can properly return FILTER_HANDLED or FILTER_STRAY when we break out of the loop. o When matching the interrupt source to the devices that have that source pending, check only from the set of devices we found to have a pending interrupt.

| | | | | | | | | | | | | | | | | | | | | | | o Properly use rman(9) to manage resources. This eliminates the need to puc-specific hacks to rman. It also allows devinfo(8) to be used to find out the specific assignment of resources to serial/parallel ports. o Compress the PCI device "database" by optimizing for the common case and to use a procedural interface to handle the exceptions. The procedural interface also generalizes the need to setup the hardware (program chipsets, program clock frequencies). o Eliminate the need for PUC_FASTINTR. Serdev devices are fast by default and non-serdev devices are handled by the bus. o Use the serdev I/F to collect interrupt status and to handle interrupts across ports in priority order. o Sync the PCI device configuration to include devices found in NetBSD and not yet merged to FreeBSD. o Add support for Quatech 2, 4 and 8 port UARTs. o Add support for a couple dozen Timedia serial cards as found in Linux.

| | | | | | | | | | | | | | | | | | | | Change fhc(4) to use IRQ numbers instead of RIDs for allocating the IRQs of children. This works similar to e.g. sbus(4), i.e. add the IRQ resources as fully specified to the resource lists of the children, allocate them like normal. When establishing the interrupt search the interrupt maps of the children for a matching INO to determine which map we need to write the fully specified interrupt number to and to enable the mapping (before the RID was used to indicate which interrupt map to use). - dev/puc/puc.c: Revert rev. 1.38, with the above change fhc(4) no longer needs special treatment for allocating IRQs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | o Introduce PUC_PORT_TYPE_UART so that we can attach to uart(4), o Introduce port sub-types (eg PUC_PORT_UART_NS8250, PUC_PORT_UART_Z8530) to handle different hardware and determine resource sizes. o Introduce two new IVARs: PUC_IVAR_SUBTYPE and PUC_IVAR_REGSHFT. Both are used by uart(4) to get sufficient information to talk to the HW. o Introduce PUC_FLAGS_ALTRES to tell puc(4) to try memory mapped I/O if I/O port space cannot be allocated, or vice versa. o Have ports of type PUC_PORT_TYPE_COM attach to uart(1) if attaching to sio(4) fails (due to not having the sio driver). o Put struct puc_device_description in struct puc_softc instead of having a pointer to a device description in the softc. This allows us to create device descriptions on the fly without having to use malloc() or otherwise have them staticly defined. o Move puc_find_description() from puc.c to puc_pci.c as it's specific to PCI. o Add EBUS and SBUS frontends for use on sparc64. Note that the P in puc stands for PCI, so we kinda mess things up here. It's too soon to worry about it though. We'll know what to do about it in time. NOTE: This commit changes the behaviour of puc(4) to not quieten the device probe and attach for child devices. The uart(4) driver provides additional device description that is valuable to have.
