* Fix the interrupt code, broken 7 months ago. The interrupt frameworkMarcel Moolenaar2011-01-291-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | already supported nested PICs, but was limited to having a nested AT-PIC only. With G5 support the need for nested OpenPIC controllers needed to be added. This was done the wrong way and broke the MPC8555 eval system in the process. OFW, as well as FDT, describe the interrupt routing in terms of a controller and an interrupt pin on it. This needs to be mapped to a flat and global resource: the IRQ. The IRQ is the same as the PCI intline and as such needs to be representable in 8 bits. Secondly, ISA support pretty much dictates that IRQ 0-15 should be reserved for ISA interrupts, because of the internal workins of south bridges. Both were broken. This change reverts revision 209298 for a big part and re-implements it simpler. In particular: o The id() method of the PIC I/F is removed again. It's not needed. o The openpic_attach() function has been changed to take the OFW or FDT phandle of the controller as a second argument. All bus attachments that previously used openpic_attach() as the attach method of the device I/F now implement as bus-specific method and pass the phandle_t to the renamed openpic_attach(). o Change powerpc_register_pic() to take a few more arguments. In particular: - Pass the number of IPIs specificly. The number of IRQs carved out for a PIC is the sum of the number of int. pins and IPIs. - Pass a flag indicating whether the PIC is an AT-PIC or not. This tells the interrupt framework whether to assign IRQ 0-15 or some other range. o Until we implement proper multi-pass bus enumeration, we have to handle the case where we need to map from PIC+pin to IRQ *before* the PIC gets registered. This is done in a similar way as before, but rather than carving out 256 IRQs per PIC, we carve out 128 IRQs (124 pins + 4 IPIs). This is supposed to handle the G5 case, but should really be fixed properly using multiple passes. o Have the interrupt framework set root_pic in most cases and not put that burden in PIC drivers (for the most part). o Remove powerpc_ign_lookup() and replace it with powerpc_get_irq(). Remove IGN_SHIFT, INTR_INTLINE and INTR_IGN. Related to the above, fix the Freescale PCI controller driver, broken by the FDT code. Besides not attaching properly, bus numbers were assigned improperly and enumeration was broken in general. This prevented the AT PIC from being discovered and interrupt routing to work properly. Consequently, the ata(4) controller stopped functioning. Fix the driver, and FDT PCI support, enough to get the MPC8555CDS going again. The FDT PCI code needs a whole lot more work. No breakages are expected, but lackiong G5 hardware, it's possible that there are unpleasant side-effects. At least MPC85xx support is back to where it was 7 months ago -- it's amazing how badly support can be broken in just 7 months...

* MFp4:Alexander Motin2009-12-061-6/+4
| | | | | | | | | | | | | | | | | | | | | Introduce ATA_CAM kernel option, turning ata(4) controller drivers into cam(4) interface modules. When enabled, this options deprecates all ata(4) peripheral drivers (ad, acd, ...) and interfaces and allows cam(4) drivers (ada, cd, ...) and interfaces to be natively used instead. As side effect of this, ata(4) mode setting code was completely rewritten to make controller API more strict and permit above change. While doing this, SATA revision was separated from PATA mode. It allows DMA-incapable SATA devices to operate and makes hw.ata.atapi_dma tunable work again. Also allow ata(4) controller drivers (except some specific or broken ones) to handle larger data transfers. Previous constraint of 64K was artificial and is not really required by PCI ATA BM specification or hardware. Submitted by: nwitehorn (powerpc part) Notes: svn path=/head/; revision=200171

* Redefine bus_space_tag_t on PowerPC from a 32-bit integral toMarcel Moolenaar2007-12-191-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | a pointer to struct bus_space. The structure contains function pointers that do the actual bus space access. The reason for this change is that previously all bus space accesses were little endian (i.e. had an explicit byte-swap for multi-byte accesses), because all busses on Macs are little endian. The upcoming support for Book E, and in particular the E500 core, requires support for big-endian busses because all embedded peripherals are in the native byte-order. With this change, there's no distinction between I/O port space and memory mapped I/O. PowerPC doesn't have I/O port space. Busses assign tags based on the byte-order only. For that purpose, two global structures exist (bs_be_tag and bs_le_tag), of which the address can be taken to get a valid tag. Obtained from: Juniper, Semihalf Notes: svn path=/head/; revision=174782
* Revamp the interrupt handling in support of INTR_FILTER. This includes:Marcel Moolenaar2007-08-111-128/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | o Revamp the PIC I/F to only abstract the PIC hardware. The resource handling has been moved to nexus, where it belongs. o Include EOI and MASK+EOI methods to the PIC I/F in support of INTR_FILTER. o With the allocation of interrupt resources and setup of interrupt handlers in the common platform code we can delay talking to the PIC hardware after enumeration of all devices. Introduce a call to powerpc_intr_enable() in configure_final() to achieve that and have powerpc_setup_intr() only program the PIC when !cold. o As a consequence of the above, remove all early_attach() glue from the OpenPIC and Heathrow PIC drivers and have them register themselves when they're found during enumeration. o Decouple the interrupt vector from the interrupt request line. Allocate vectors increasingly so that they can be used for the intrcnt index as well. Extend the Heathrow PIC driver to translate between IRQ and vector. The OpenPIC driver already has the support for vectors in hardware. Approved by: re (blanket) Notes: svn path=/head/; revision=171805
