* Reapply, with minor tweaks, r338025, from the original commit:Warner Losh2018-09-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove unused and easy to misuse PNP macro parameter Inspired by r338025, just remove the element size parameter to the MODULE_PNP_INFO macro entirely. The 'table' parameter is now required to have correct pointer (or array) type. Since all invocations of the macro already had this property and the emitted PNP data continues to include the element size, there is no functional change. Mostly done with the coccinelle 'spatch' tool: $ cat modpnpsize0.cocci @normaltables@ identifier b,c; expression a,d,e; declarer MODULE_PNP_INFO; @@ MODULE_PNP_INFO(a,b,c,d, -sizeof(d[0]), e); @singletons@ identifier b,c,d; expression a; declarer MODULE_PNP_INFO; @@ MODULE_PNP_INFO(a,b,c,&d, -sizeof(d), 1); $ rg -l MODULE_PNP_INFO -- sys | \ xargs spatch --in-place --sp-file modpnpsize0.cocci (Note that coccinelle invokes diff(1) via a PATH search and expects diff to tolerate the -B flag, which BSD diff does not. So I had to link gdiff into PATH as diff to use spatch.) Tinderbox'd (-DMAKE_JUST_KERNELS). Approved by: re (glen) Notes: svn path=/head/; revision=338948

* 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

* Extend the meaning of the CTLFLAG_TUN flag to automatically check ifHans Petter Selasky2014-06-271-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | there is an environment variable which shall initialize the SYSCTL during early boot. This works for all SYSCTL types both statically and dynamically created ones, except for the SYSCTL NODE type and SYSCTLs which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to be used in the case a tunable sysctl has a custom initialisation function allowing the sysctl to still be marked as a tunable. The kernel SYSCTL API is mostly the same, with a few exceptions for some special operations like iterating childrens of a static/extern SYSCTL node. This operation should probably be made into a factored out common macro, hence some device drivers use this. The reason for changing the SYSCTL API was the need for a SYSCTL parent OID pointer and not only the SYSCTL parent OID list pointer in order to quickly generate the sysctl path. The motivation behind this patch is to avoid parameter loading cludges inside the OFED driver subsystem. Instead of adding special code to the OFED driver subsystem to post-load tunables into dynamically created sysctls, we generalize this in the kernel. Other changes: - Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask" to "hw.pcic.intr_mask". - Removed redundant TUNABLE statements throughout the kernel. - Some minor code rewrites in connection to removing not needed TUNABLE statements. - Added a missing SYSCTL_DECL(). - Wrapped two very long lines. - Avoid malloc()/free() inside sysctl string handling, in case it is called to initialize a sysctl from a tunable, hence malloc()/free() is not ready when sysctls from the sysctl dataset are registered. - Bumped FreeBSD version to indicate SYSCTL API change.

* Add MSI support to puc(9)Ryan Stone2014-03-131-2/+53
| | | | | | | | | | | | | | Add support for MSI interrupts in the puc(9) driver. By default the driver will prefer MSI interrupts to legacy interrupts. A tunable, hw.puc.msi_disable, has been added to force the allocation of legacy interrupts. Reviewed by: jhb@ MFC after: 2 weeks Sponsored by: Sandvine Inc. Notes: svn path=/head/; revision=263109

Interestingly, these are actually the default for quite some time (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9) since r52045) but even recently added device drivers do this unnecessarily.

* Rewrite of puc(4). Significant changes are:Marcel Moolenaar2006-04-281-182/+33
| | | | | | | | | | | | | | | | | | | | | | | 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.

* Enhance puc(4) to support uart(4). This includes:Marcel Moolenaar2003-09-061-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | Don't expect all RIDs to be PCI rids. The previous code made at least 1 mistake, even for PCI. Give the card definitions a chance to specify a init function. Use this instead of the gross superio hack. Move the win877 init function to puc_pci.c where it belongs. RIDs can actually be zero, don't set badmuxed if so. Set a less incorrect end for the construct SYS_RES_IOPORT entries, I guess both sio and lpt happen to use 8 IO ports, but that shouldn't really be hardcoded this way. Fixup puc_pccard.c to match.
