Some clean-up, style changes and changes that will reduce differences between this driver and other Host-PCI bridge drivers based on this one: - Make the code fit into 80 columns. - Make the code adhere style(9) (don't use function calls in initializers, use uintXX_t instead of u_intXX_t, add missing prototypes, ...). - Remove unused and superfluous struct declaration, softc member, casts, includes, etc. - Use FBSDID. - Sprinkle const. - Try to make comments and messages consistent in style throughout the driver. - Use convenience macros for the number of interrupts and ranges of the bridge. - Use __func__ instead of hardcoded function names in panic strings and error messages. Some of the hardcoded function names actually were outdated through moving code around. [1] - Rename softc members related to the PCI side of the bridge to sc_pci_* in order to make it clear which side of the bridge they refer to (so stuff like sc_bushandle vs. sc_bh is less confusing while reading the code).

o Revamp the sparc64 interrupt code in order to be able to interface with the INTR_FILTER-enabled MI code. Basically this consists of registering an interrupt controller (of which there can be multiple and optionally different ones either per host-to-foo bridge or shared amongst host-to-foo bridges in any one machine) along with an interrupt vector as specific argument for all the interrupt vectors used by a given host-to-foo bridge (roughly similar to registering interrupt sources on amd64 and i386), providing functions to enable, clear and disable the interrupts of the children beneath the bridge. This also includes: - No longer entering a critical section in tl0_intr() and tl1_intr() for executing interrupt handlers but rather let the handlers enter it themselves so in the case of intr_event_handle() we don't enter a nested critical section. - Adding infrastructure for binding delivery of interrupt vectors to specific CPUs which later on can be interfaced with the code from amd64/i386 for binding interrupts to specific CPUs. - Getting rid of the wrapper hack introduced along the lines of the API changes for INTR_FILTER which as a side-effect caused interrupts associated with ithread handlers only to get the elevated priority of those associated with filters ("fast handlers") (this removes the hack also in the non-INTR_FILTER case). - Disabling (by not clearing) an interrupt in the interrupt controller until all associated handlers have been executed, which is crucial for the typical locking strategy of NIC drivers in order to work correctly in case of shared interrupts. This was a more or less theoretical problem on sparc64 though, as shared interrupts are rather uncommon there except for the on-board SCCs and UARTs. Note that due to the behavior of at least of some of the interrupt controllers used on sparc64 an enable+EOI instead of a disable+EOI approach (as implied by the INTR_FILTER MI code and implemented on other architectures) is used as the latter can cause lost interrupts or in the worst case interrupt starvation. o Correct a typo in sbus_alloc_resource() which caused (pass-through) allocations to only work down to the grandchildren of the bus, which wasn't a real problem so far as we don't support any devices which are great-grandchildren or greater of a U2S bridge, yet. o In fhc(4) use bus_{read,write}_4() instead of bus_space_{read,write}_4() in order to get rid of sc_bh and sc_bt in the fhc_softc. Also get rid of some other unneeded members in fhc_softc. Reviewed by: marcel (earlier version) Approved by: re (kensmith)

Some clean-up, style changes and changes that will reduce differences between this driver and other Host-PCI bridge drivers based on this one: - Make the code fit into 80 columns. - Make the code adhere style(9) (don't use function calls in initializers, use uintXX_t instead of u_intXX_t, add missing prototypes, ...). - Remove unused and superfluous struct declaration, softc member, casts, includes, etc. - Use FBSDID. - Sprinkle const. - Try to make comments and messages consistent in style throughout the driver. - Use convenience macros for the number of interrupts and ranges of the bridge. - Use __func__ instead of hardcoded function names in panic strings and error messages. Some of the hardcoded function names actually were outdated through moving code around. [1] - Rename softc members related to the PCI side of the bridge to sc_pci_* in order to make it clear which side of the bridge they refer to (so stuff like sc_bushandle vs. sc_bh is less confusing while reading the code).

- Improve the comment regarding the workaround for the E250 interrupt map bug by explaining what the problem is and how the workaround works. - Fix some cosmetics nits, mainly properly terminate sentences in comments, which I missed when backporting the style changes to psycho(4) in psycho.c rev. 1.54 due to lack of corresponding code. - The "USIIe version of the Sabre bridge" actually is termed "Hummingbird"; name it as such in comments and messages.

o Changes to psycho_attach(): [1] - Clear the PCI AFSR and status error bits as previous errors still might be indicated. - Set up the PCI control and diagnostic registers according to the capabilities, workarounds, etc of/for specific revisions of the supported bridges. This includes no longer setting Hummingbird-/ Sabre-specific bits in the PCI control register but preserving what the firmware has initialized them to like OpenSolaris does. Previously we were setting these bits according to the example in the Sabre documentation, which I doubt is appropriate for all Sabre based designs and especially not for Hummingbirds. This also includes not enabling bus parking unless the firmware tells us to. - Set the PCI latency timer register as this isn't always done by the firmware. o Remove a redundant argument from psycho_set_intr() and in this function check the return value of bus_setup_intr(). [2] o Let psycho_setup_intr() return ENOMEM instead of 0 when it can't allocate memory for the interrupt wrapper stub and EINVAL instead of 0 if it can't find the interrupt vector in the interrupt map. o Add a workaround for a bug of the Sabre-APB-combination where it doesn't drain DMA write data for devices behind additional PCI-PCI bridges underneath the APB PCI-PCI bridge. This workaround (do things necessary in order to achieve a manual drain when coherency is required) is currently implemented in psycho_setup_intr() and psycho_intr_stub() (for easy MFC'ing) and therefore is only applied for interrupt handlers. This should be moved to psycho(4)-specific bus_dma_tag_create() and bus_dmamap_sync() methods, respectively, once this driver is converted to make use of BUS_GET_DMA_TAG(), so the workaround is also applied for polling(4) callbacks.

The former is required to get some e450 models to boot; the latter fixes the repeated fifo underruns with hme(4)s and gem(4)s observed on some machines (and probably performance problems with other peripherals as well).

- Divorce the IOTSBs, which so far where handled via a global list instead of per IOMMU, so we no longer need to program all of them identically in systems having multiple IOMMUs. This continues the rototilling of the nexus(4) done about 5 months ago, which amongst others changed nexus(4) and the drivers for host-to-foo bridges to provide bus_get_dma_tag methods, allowing to handle DMA tags in a hierarchical way and to link them with devices. This still doesn't move the silicon bug workarounds for Sabre (and in the uncommitted schizo(4) for Tomatillo) bridges into special bus_dma_tag_create() and bus_dmamap_sync() methods though, as w/o fully newbus'ified bus_dma_tag_create() and bus_dma_tag_destroy() this still requires too much hackery, i.e. per-child parent DMA tags in the parent driver. - Let the host-to-foo drivers supply the maximum physical address of the IOMMU accompanying the bridges. Previously iommu(4) hard- coded an upper limit of 16GB, which actually only applies to the IOMMUs of the Hummingbird and Sabre bridges. The Psycho variants as well as the U2S in fact can can translate to up to 2TB, i.e. translate to 41-bit physical addresses. According to the recently available Tomatillo documentation these bridges even translate to 43-bit physical addresses and hints at the Schizo bridges doing 43 bits as well. This fixes the issue the FreeBSD 6.0 todo list item "Max RAM on sparc64" was refering to and pretty much obsoletes the lack of support for bounce buffers on sparc64. Thanks to Nathan Whitehorn for pointing me at the Tomatillo manual. Approved by: re (kensmith)

Some clean-up, style changes and changes that will reduce differences between this driver and other Host-PCI bridge drivers based on this one: - Make the code fit into 80 columns. - Make the code adhere style(9) (don't use function calls in initializers, use uintXX_t instead of u_intXX_t, add missing prototypes, ...). - Remove unused and superfluous struct declaration, softc member, casts, includes, etc. - Use FBSDID. - Sprinkle const. - Try to make comments and messages consistent in style throughout the driver. - Use convenience macros for the number of interrupts and ranges of the bridge. - Use __func__ instead of hardcoded function names in panic strings and error messages. Some of the hardcoded function names actually were outdated through moving code around. [1] - Rename softc members related to the PCI side of the bridge to sc_pci_* in order to make it clear which side of the bridge they refer to (so stuff like sc_bushandle vs. sc_bh is less confusing while reading the code).
