thorpej | branches: 1.27.8; Merge thorpej-cfargs branch:
Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments.
Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.)
Remove unnecessary or redundant interface attributes where they're not needed.
There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)
...and a sentinel value CFARG_EOL.
Add some extra sanity checking to ensure that interface attributes aren't ambiguous.
Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

dyoung | PCI_FLAGS_IO_ENABLED and PCI_FLAGS_MEM_ENABLED changed their functional role in NetBSD (drivers are no longer supposed to write these to pa_flags) without changing name. Correct that.
Rename PCI_FLAGS_IO_ENABLED to PCI_FLAGS_IO_OKAY and PCI_FLAGS_MEM_ENABLED to PCI_FLAGS_MEM_OKAY, thus making their names consistent with the other PCI flags and poisoning 3rd-party driver sources that use the flags in the old bad way.
This patch produces no binary changes in this set of PCI kernels when they are compiled w/o 'options DIAGNOSTIC' and w/ -V MKREPRO=yes:

chris | branches: 1.18.10; 1.18.18; 1.18.24; Fix for PR cats/18026.
cats was never able to dump a kernel core dump because reading from VGA addresses (0xb8000) was causing the system to hang.
To workaround this reprogram the footbridge to map the memory to appear on the PCI bus at 0x20000000, rather than at 0x0. Also configure the pci bus to have a DMA range so that data is mapped correctly.
Note that -current kernels seem to hang when unmounting the fs. This is a seperate issue, and appears to be because interrupts need to be enabled to unmount filesystems.
So using reboot 0x104 does work, as it does a sync without unmounting the filesystems.
Also arm savecore doesn't do anything with the memroy dump, as on arm we currently just dump the raw memory, there's no header block to indicate memory sizes or other useful information.

drochner | branches: 1.15.12; Phase out the use of a string as first "attach args" member to control which bustype should be attached with a specific call to config_found() (from a "mainbus" or a bus bridge). Do it for isa/eisa/mca and pci/agp for now. These buses all attach to an mi interface attribute "isabus", "eisabus" etc., and the autoconf framework now allows to specify an interface attribute on config_found() and config_search(), which limits the search of matching config data to these which attach to that specific attribute. So we basically have to call config_found_ia(..., "foobus", ...) where such a bus is attached. As a consequence, where a "mainbus" or alike also attaches other devices (eg CPUs) which do not attach to a specific attribute yet, we need at least pass an attribute name (different from "foobus") so that the foo bus is not found at these places. This made some minor changes necessary which are not obviously related to the mentioned buses.

fvdl | branches: 1.14.2; Handle 64bit DMA addresses on PCI for platforms that can (currently only enabled on amd64). Add a dmat64 field to various PCI attach structures, and pass it down where needed. Implement a simple new function called pci_dma64_available(pa) to test if 64bit DMA addresses may be used. This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>, and there is more than 4G of memory.

chris | Checkin new interrupt handling code for the footbridge. This is based upon Jason's work on xscale.
Most of the interrupt handling code is now written in C using an asm stub to call into the C code.
spl* now only updates a software mask, and does not update the hardware, this should be much faster.
The new code works well on cats, it's untested on netwinder, but should work.
The code implements generic soft interrupts.
More work is still required to bring the isa interrupt handling code upto scratch currently all isa interrupts are handled at IPL_BIO on the footbridge. This may cause isa interrupts to be handled later than they should be. I plan to fix this in the near future.

thorpej | * Add "pcitag_t *pba_bridgetag" to pci_attach_args. This is set to NULL for root PCI busses. For busses behind a bridge, it points to a persistent copy of the bridge's pcitag_t. This can be very useful for machine-dependent PCI bus enumeration code. * Implement a machine-dependent pci_enumerate_bus() for sparc64 which uses OFW device nodes to enumerate the bus. When a PCI bus that is behind a bridge is attached, pci_attach_hook() allocates a new PCI chipset tag for the new bus and sets it's "curnode" to the OFW node of the bridge. This is used as a starting point when enumerating that bus. Root busses get the OFW node of the host bridge (psycho). * Garbage-collect "ofpci" and "ofppb" from the sparc64 port.

chris | branches: 1.6.2; Implement a proper delay routine for footbridge based systems. Note that until the footbridge is attached we still have to rely on a loop. This uses TIMER_3 running at 100Hz. Sadly this doesn't appear to fix the tlp problems, which either means that this delay routine is not as accurate as it should/could be or tlp is still broken.

thorpej | Centralize ARM CPU configuration information by adding a new header file, <arm/cpuconf.h>, which pulls in "opt_cputypes.h" and then defines the following: * CPU_NTYPES -- now many CPU types are configured into the kernel. What you really want to know is "== 1" or "> 1". * Defines ARM_ARCH_2, ARM_ARCH_3, ARM_ARCH_4, ARM_ARCH_5, depending on which ARM architecture versions are configured (based on CPU_* options). Also defines ARM_NARCH to determins how many architecture versions are configured. * Defines ARM_MMU_MEMC, ARM_MMU_GENERIC, ARM_MMU_XSCALE depending on which classes of ARM MMUs are configured into the kernel, and ARM_NMMUS to determine how many MMU classes are configured.
Remove the needless inclusion of "opt_cputypes.h" in several places. Convert remaining users to <arm/cpuconf.h>.

chris | Initial check-in of reworked arm interrupt routines.
Main things to note on this branch: * spl routines are inlined, less complex, and small (kernel drops in size) * interrupts are handled in priority order (for most things it doesn't matter, but pending ipls are used to determine if there is any work to do) * arm_irqhandler.c is derived from footbridge_irqhandler.c, which was based on work by thorpej. * The code tries to touch hardware as little as possible. * spl masks are no longer tracked, as the system is based on pending ipls
The shared code uses global ipl lists to track which interrupt handlers are attached to which ipl (arm_iplq[]).
Interrupt sources register with the common code to indicate: * how many irq lines they have * a function to set the hardware mask. * call arm_intr_claim and arm_intr_disestablish to setup handlers
When an interrupt occurs the ipl is flagged as pending, in ipls_pending. If it can be handled at the current_ipl_level the code does so. If it can't be handled it's left until the current_ipl_level drops.
As the ipl level changes down a quick test is made of the new ipl level against the ipls_pending value. If an ipl is pending arm_intr_splx_lifter is called to handle the pending ipls.
It should be noted that all interrupts are left enabled at the hardware level, interrupts are only masked when they occur. They are only re-enabled after it's interrupt handler is called. Hardware masks are not changed at any other time.
Soft interrupts are treated the same as hardware interrupts, they register as a provider, and do not get treated specially. All the soft interrupt handlers are placed onto the relevant global ipl queue, the same as hard interrupts handlers.
At the moment only footbridge within a cats has been updated to use the new handling.
Todo: * change the handling of interrupts, so that the hardware doesn't register a routine to fetch the hardware status. Instead is makes a call which provides the mask. This removes the primary flag when registering an interrupt provider. It also makes more sense with multiple interrupt sources. * Arm v5 has the clz asm, which could be used instead of the carefully hand rolled arm_intr_fls function. * switch cats isa support to use this framework. * switch iomd and acorn32 to use this framework. * switch shark to use this framework. * port any other arm platforms that are interested * examine overlaps between this code and ppcoea-renovation branch. * add support for different trigger types (Edge, level, pulse, etc)
(note that iomd and shark currently touch hardware on every spl change, hence why they're targets to port)
