Sat, 21 Feb 2026 07:14:46 +0100

chore: replace {0, 0} with {DEV,KOBJ}METHOD_ENDBoth of the aforementioned macros have been present in FreeBSDfor well over a decade: 2009 for `KOBJMETHOD_END`; 2011 for`DEVMETHOD_END`.Adapt all hardcoded references of `{0, 0}` with `DEVMETHOD_END`and `KOBJMETHOD_END` as appropriate. This helps ensure thatfuture adaptations to drivers following patterns documentedin driver(9) can be made more easily/without issue.MFC after: 1 weekDifferential Revision: https://reviews.freebsd.org/D55414 List of files: /freebsd/sys/dev/ppc/ppc_puc.c

718cf2ccb9956613756ab15d7a0e28f2c8e91cab - sys/dev: further adoption of SPDX licensing ID tags.

Mon, 27 Nov 2017 15:52:40 +0100

sys/dev: further adoption of SPDX licensing ID tags.Mainly focus on files that use BSD 2-Clause license, however the tool Iwas using misidentified many licenses so this was mostly a manual - errorprone - task.The Software Package Data Exchange (SPDX) group provides a specificationto make it easier for automated tools to detect and summarize well knownopensource licenses. We are gradually adopting the specification, notingthat the tags are considered only advisory and do not, in any way,superceed or replace the license texts.

2067d312d40c5e179c240a796d047fe4c8e276ee - Add locking to ppc and ppbus and mark the whole lot MPSAFE:

Thu, 22 Jan 2009 00:10:06 +0100

Add locking to ppc and ppbus and mark the whole lot MPSAFE:- To avoid having a bunch of locks that end up always getting acquired as a group, give each ppc(4) device a mutex which it shares with all the child devices including ppbus(4), lpt(4), plip(4), etc. This mutex is then used for all the locking.- Rework the interrupt handling stuff yet again. Now ppbus drivers setup their interrupt handler during attach and tear it down during detach like most other drivers. ppbus(4) only invokes the interrupt handler of the device that currently owns the bus (if any) when an interrupt occurs, however. Also, interrupt handlers in general now accept their softc pointers as their argument rather than the device_t. Another feature of the ppbus interrupt handlers is that they are called with the parent ppc device's lock already held. This minimizes the number of lock operations during an interrupt.- Mark plip(4), lpt(4), pcfclock(4), ppi(4), vpo(4) MPSAFE.- lpbb(4) uses the ppc lock instead of Giant.- Other plip(4) changes: - Add a mutex to protect the global tables in plip(4) and free them on module unload. - Add a detach routine. - Split out the init/stop code from the ioctl routine into separate functions.- Other lpt(4) changes: - Use device_printf(). - Use a dedicated callout for the lptout timer. - Allocate the I/O buffers at attach and detach rather than during open and close as this simplifies the locking at the cost of 1024+32 bytes when the driver is attached.- Other ppi(4) changes: - Use an sx lock to serialize open and close. - Remove unused HADBUS flag. - Add a detach routine. - Use a malloc'd buffer for each read and write to avoid races with concurrent read/write.- Other pps(4) changes: - Use a callout rather than a callout handle with timeout(). - Conform to the new ppbus requirements (regular mutex, non-filter interrupt handler). pps(4) is probably going to have to become a standalone driver that doesn't use ppbus(4) to satisfy it's requirements for low latency as a result. - Use an sx lock to serialize open and close.- Other vpo(4) changes: - Use the parent ppc device's lock to create the CAM sim instead of Giant.- Other ppc(4) changes: - Fix ppc_isa's detach method to detach instead of calling attach.Tested by: no one :-( List of files: /freebsd/sys/dev/ppc/ppc_puc.c

ca3d37955c7c41e64a80c97b3f1c1fa4e9ff4897 - Rework the handling of interrupt handlers for children of ppc and ppbus:

Tue, 16 Sep 2008 00:26:32 +0200

Rework the handling of interrupt handlers for children of ppc and ppbus:- Retire IVARs for passing IRQs around. Instead, ppbus and ppc now allow child devices to access the interrupt by via a rid 0 IRQ resource using bus_alloc_resource_any().- ppc creates its own interrupt event to manage the interrupt handlers of child devices. ppc does not allow child devices to use filters. It could allow this if needed, but none of the current drivers use them and it adds a good bit of complication. It uses intr_event_execute_handlers() to fire the child device interrupt handlers from its threaded interrupt handler.- Remove the ppbus_dummy_intr() hack. Now the ppc device always has an interrupt handler registered and we no longer bounce all the way up to nexus to manage adding/removing ppbus child interrupt handlers. Instead, the child handlers are added and removed to the private interrupt event in the ppc device. List of files: /freebsd/sys/dev/ppc/ppc_puc.c

64220a7e28f7124b98734c60dbd17a13a3e22822 - Rewrite of puc(4). Significant changes are:

Fri, 28 Apr 2006 23:21:53 +0200

Rewrite of puc(4). Significant changes are: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.

Tue, 25 Apr 2006 01:31:51 +0200

o Move ISA specific code from ppc.c to ppc_isa.c -- a bus front- end for isa(4).o Add a seperate bus frontend for acpi(4) and allow ISA DMA for it when ISA is configured in the kernel. This allows acpi(4) attachments in non-ISA configurations, as is possible for ia64.o Add a seperate bus frontend for pci(4) and detect known single port parallel cards.o Merge PC98 specific changes under pc98/cbus into the MI driver. The changes are minor enough for conditional compilation and in this form invites better abstraction.o Have ppc(4) usabled on all platforms, now that ISA specifics are untangled enough.
