* ata_kauai: Fix support for "shasta" controllers.John Baldwin2022-05-131-14/+10
| | | | | | | | | | | | | | | | | | | | | The probe routine was setting a value in the softc, but since the probe routine was not returning zero, this value was lost since the softc was reallocated (and re-zeroed) when the device was attached. This is similar in nature to the fixes from 965205eb66cae3fd5de75a70a3aef2f014f98020. To fix, move the code to set the 'shasta' flag to the start of attach along with related code to set an IRQ resource on some non-shasta devices. The IRQ resource still "worked" being in the probe routine as the IRQ resource persisted after probe returned, but it is cleaner to go ahead and move it to attach after setting the 'shasta' flag. I have no way to test this, but noticed this while reading the code.

* Extract eventfilter declarations to sys/_eventfilter.hConrad Meyer2019-05-205-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h" in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header pollution substantially. EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c files into appropriate headers (e.g., sys/proc.h, powernv/opal.h). As a side effect of reduced header pollution, many .c files and headers no longer contain needed definitions. The remainder of the patch addresses adding appropriate includes to fix those files. LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by sys/mutex.h since r326106 (but silently protected by header pollution prior to this change). No functional change (intended). Of course, any out of tree modules that relied on header pollution for sys/eventhandler.h, sys/lock.h, or sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.

* powerpc/powermac: Fix macgpio(4) child interrupt resource handlingJustin Hibbits2018-12-061-4/+4
| | | | | | | | | | | | | | | | The 'interrupts' property is actually 2 words, not one, on macgpio child nodes. Open Firmware's getprop function might be returning the value copied, not the total size of the property, but FDT's returns the total size. Prior to this patch, this would cause the SYS_RES_IRQ resource list to not be populated when running with the 'usefdt' loader variable set, to convert the OFW device tree to a FDT. Since the property is always 2 words, read both words, and ignore the second. Tested by: Dennis Clarke (previous attempt) MFC after: 2 weeks Notes: svn path=/head/; revision=341614

| | | | | | | | | | | | | | | | Mark some buses as BUS_PASS_BUS, and some resources as BUS_PASS_RESOURCE. This also decouples some resource attachment orderings from being races by device tree ordering, instead relying on the bus pass to provide the ordering. This was originally intended to support multipass suspend/resume, but it's also needed on PowerMacs when using fdt, as the device tree seems to get created in reverse of the OFW tree.

* Clean up OF_getprop_alloc APIOleksandr Tymoshenko2018-04-082-7/+7
| | | | | | | | | | | | | | | | | | | | OF_getprop_alloc takes element size argument and returns number of elements in the property. There are valid use cases for such behavior but mostly API consumers pass 1 as element size to get string properties. What API users would expect from OF_getprop_alloc is to be a combination of malloc + OF_getprop with the same semantic of return value. This patch modifies API signature to match these expectations. For the valid use cases with element size != 1 and to reduce modification scope new OF_getprop_alloc_multi function has been introduced that behaves the same way OF_getprop_alloc behaved prior to this patch.

* Use uintmax_t (typedef'd to rman_res_t type) for rman ranges.Justin Hibbits2016-03-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some architectures, u_long isn't large enough for resource definitions. Particularly, powerpc and arm allow 36-bit (or larger) physical addresses, but type `long' is only 32-bit. This extends rman's resources to uintmax_t. With this change, any resource can feasibly be placed anywhere in physical memory (within the constraints of the driver). Why uintmax_t and not something machine dependent, or uint64_t? Though it's possible for uintmax_t to grow, it's highly unlikely it will become 128-bit on 32-bit architectures. 64-bit architectures should have plenty of RAM to absorb the increase on resource sizes if and when this occurs, and the number of resources on memory-constrained systems should be sufficiently small as to not pose a drastic overhead. That being said, uintmax_t was chosen for source clarity. If it's specified as uint64_t, all printf()-like calls would either need casts to uintmax_t, or be littered with PRI*64 macros. Casts to uintmax_t aren't horrible, but it would also bake into the API for resource_list_print_type() either a hidden assumption that entries get cast to uintmax_t for printing, or these calls would need the PRI*64 macros. Since source code is meant to be read more often than written, I chose the clearest path of simply using uintmax_t. Tested on a PowerPC p5020-based board, which places all device resources in 0xfxxxxxxxx, and has 8GB RAM.

| | | | | | | | | | | | | | | | | | | | | | | 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.
