* [SPARC64]: Add sun4v_cpu_qconf() hypervisor call.David S. Miller2006-03-20
| | | | | | Call it from register_one_mondo(). Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: do_fptrap needs to load the thread reg into %g6.David S. Miller2006-03-20
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix bogus call to sun4v_mna in winfixup code.David S. Miller2006-03-20
| | | | | | The C function is named sun4v_do_mna not sun4v_mna. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix tl1 trap state capture/dump on SUN4V.David S. Miller2006-03-20
| | | | | | No trap levels above 2 in privileged mode on SUN4V. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64] PCI: Size TSB correctly on SUN4V.David S. Miller2006-03-20
| | | | | | | | | Forgot to multiply by 8 * 1024, oops. Correct the size constant when the virtual-dma arena is 2GB in size, it should bet 256 not 128. Finally, log some info about the TSB at probe time. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Don't use ASI_QUAD_LDD_PHYS on SUN4V.David S. Miller2006-03-20
| | | | | | Need to use ASI_QUAD_LDD_PHYS_4V instead. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Do not write garbage into %pstate in tsb_context_switch().David S. Miller2006-03-20
| | | | | | | | For SUN4V, we were clobbering %o5 to do the hypervisor call. This clobbers the saved %pstate value and we end up writing garbage into that register as a result. Oops. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix flush_tsb_user() on SUN4V.David S. Miller2006-03-20
| | | | | | Needs to use physical addressing just like cheetah_plus. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix comment typo in __flush_tlb_kernel_range.David S. Miller2006-03-20
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Decode virtual-devices interrupts correctly.David S. Miller2006-03-20
| | | | | | Need to translate through the interrupt-map{,-mask] properties. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Add prom_{start,stop}cpu_cpuid().David S. Miller2006-03-20
| | | | | | | | | Use prom_startcpu_cpuid() on SUN4V instead of prom_startcpu(). We should really test for "SUNW,start-cpu-by-cpuid" presence and use it if present even on SUN4U. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix pci_intmap_match().David S. Miller2006-03-20
| | | | | | | | | | When crawling up the PCI bus chain, stop at the first node that has an interrupt-map property before we hit the root. Also, if we use a bus interrupt-{map,mask} do not forget to update the 'intmask' pointer as we do for the 'intmap' pointer. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Two IRQ handling fixes.David S. Miller2006-03-20
| | | | | | | | | On SUN4V, force IRQ state to idle in enable_irq(). However, I'm still not sure this is %100 correct. Call add_interrupt_randomness() on SUN4V too. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Use different cache sizing defaults on SUN4V.David S. Miller2006-03-20
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Make lack of interrupt-map-* a fatal error on SUN4V.David S. Miller2006-03-20
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix sun4v_intr_setenabled() return value check in enable_irq().David S. Miller2006-03-20
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Explicitly init *nregs to 0 in find_device_prom_node().David S. Miller2006-03-20
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Restrict PCI bus scanning on SUN4V.David S. Miller2006-03-20
| | | | | | | | | | | | | On the PBM's first bus number, only allow device 0, function 0, to be poked at with PCI config space accesses. For some reason, this single device responds to all device numbers. Also, reduce the verbiage of the debugging log printk's for PCI cfg space accesses in the SUN4V PCI controller driver, so that it doesn't overwhelm the slow SUN4V hypervisor console. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix C-function name called by sun4v_mna trap code.David S. Miller2006-03-20
| | | | | | The trap code was calling itself :-) Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Don't printk() any messaages in sun4v_build_irq().David S. Miller2006-03-20
| | | | | | It just clutters up the log. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: INO is never fully specified already on SUN4V.David S. Miller2006-03-20
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Kill sun4v_register_fault_status() on SMP.David S. Miller2006-03-20
| | | | | | | That now gets done as a side effect of taking over the trap table from OBP. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: arch/sparc64/kernel/trampoline.S needs asm/cpudata.hDavid S. Miller2006-03-20
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Make error codes available from sun4v_intr_get*().David S. Miller2006-03-20
| | | | | | And check for errors at call sites. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Pass correct ino to sun4v_intr_*().David S. Miller2006-03-20
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Use TRAP_LOAD_IRQ_WORK() in sun4v device mondo handler.David S. Miller2006-03-20
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix IOMMU mapping on sun4v.David S. Miller2006-03-20
| | | | | | | | | | We should dynamically allocate the per-cpu pglist not use an in-kernel-image datum, since __pa() does not work on such addresses. Also, consistently use "u32" for devhandle. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Trim down sun4v IRQ translation kernel log message.David S. Miller2006-03-20
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64] sunhv: Bug fixes.David S. Miller2006-03-20
| | | | | | | | | | | | | | | Add udelay to polling console write loop, and increment the loop limit. Name the device "ttyHV" and pass that to add_preferred_console() when we're using hypervisor console. Kill sunhv_console_setup(), it's empty. Handle the case where we don't want to use hypervisor console. (ie. we have a head attached to a sun4v machine) Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Probe virtual-devices root node on sun4v.David S. Miller2006-03-20
| | | | | | | This is where we learn how to get the interrupts for things like the hypervisor console device. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Kill spurious semicolon in sun4v_pci_init().David S. Miller2006-03-20

* [SPARC64]: Program IRQ registers correctly on sun4v.David S. Miller2006-03-20
| | | | | | | Need to use hypervisor calls instead of direct register accesses. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Generic sun4v_build_irq().David S. Miller2006-03-20
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: More SUN4V PCI work.David S. Miller2006-03-20
| | | | | | | | | | | Get bus range from child of PCI controller root nexus. This is actually a hack, but the PCI-E bridge sitting at the top of the PCI tree responds to PCI config cycles for every device number, so best to just ignore it for now. Preliminary PCI irq routing, needs lots of work. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Log faulting vaddr when bogus kernel PC detected.David S. Miller2006-03-20

* [SPARC64]: Move devino_to_sysino out of pci_sun4v_asm.SDavid S. Miller2006-03-20
| | | | | | It is not PCI specific, it is for all system interrupts. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Range check bus number in SUN4V PCI controller driver.David S. Miller2006-03-20
| | | | | | | It has to be somewhere in the range from pbm->pci_first_busno to pbm->pci_last_busno, inclusive. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Missing 'return' statement in sun4v_pci_init().David S. Miller2006-03-20

* [SPARC64]: PCI-SUN4V fixes.David S. Miller2006-03-20
| | | | | | | | | Clear top 8-bits of physical addresses in "ranges" property. This gives the actual physical address. Detect PBM-A vs. PBM-B by checking bit 0x40 of the devhandle. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Use inline patching for critical PTE operations.David S. Miller2006-03-20
| | | | | | | This handles the SUN4U vs SUN4V PTE layout differences with near zero performance cost. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Move PTE field definitions back into asm/pgtable.hDavid S. Miller2006-03-20
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Don't expect cfg space in PCI PBM ranges on SUN4V.David S. Miller2006-03-20
| | | | | | | PCI cfg space is accessed transparently through the Hypervisor and not through direct cpu PIO operations. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix branch signedness bug in all code patching.David S. Miller2006-03-20
| | | | | | | The bug that hit SUN4V TLB patching exists elsewhere. Make sure we cure all such cases. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Recognize "virtual-console" as input and output console device.David S. Miller2006-03-20
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Do not try to synchronize %stick registers on SUN4V.David S. Miller2006-03-20
| | | | | | Writes by privileged code are not allowed. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Do not try to write to %tick or %stick on SUN4V.David S. Miller2006-03-20
| | | | | | | Writes by privileged code are disallowed. The hypervisor manages the non-privileged bit. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix mondo queue allocations.David S. Miller2006-03-20
| | | | | | | | | | We have to use bootmem during init_IRQ and page alloc for sibling cpu calls. Also, fix incorrect hypervisor call return value checks in the hypervisor SMP cpu mondo send code. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Deal with PTE layout differences in SUN4V.David S. Miller2006-03-20
| | | | | | | | | | Yes, you heard it right, they changed the PTE layout for SUN4V. Ho hum... This is the simple and inefficient way to support this. It'll get optimized, don't worry. Signed-off-by: David S. Miller <davem@davemloft.net>
