* [SPARC64]: Warn user if cpu is ignored.David S. Miller2007-09-16
| | | | | | | | | When NR_CPUS is smaller than the cpu probed, let the user know that the cpu won't be used. Suggested by Al Viro. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix lockdep, particularly on SMP.David S. Miller2007-09-16
| | | | | | | | | | | | | | | | | | | | | | | As noted by Al Viro, when we try to call prom_set_trap_table() in the SMP trampoline code we try to take the PROM call spinlock which doesn't work because the current thread pointer isn't valid yet and lockdep depends upon that being correct. Furthermore, we cannot set the current thread pointer register because it can't be properly dereferenced until we return from prom_set_trap_table(). Kernel TLB misses only work after that call. So do the PROM call to set the trap table directly instead of going through the OBP library C code, and thus avoid the lock altogether. These calls are guarenteed to be serialized fully. Since there are now no calls to the prom_set_trap_table{_sun4v}() library functions, they can be deleted. Signed-off-by: David S. Miller <davem@davemloft.net>

* [SPARC64]: Fix booting on V100 systems.David S. Miller2007-09-12
| | | | | | | | | | | | | | On the root PCI bus, the OBP device tree lists device 3 twice. Once as 'pm' and once as 'lomp'. Everything goes downhill from there. Ignore the second instance to workaround this. Thanks to Kövedi_Krisztián for the bug report and testing the fix. Signed-off-by: David S. Miller <davem@davemloft.net>
* hugepage: fix broken check for offset alignment in hugepage mappingsDavid Gibson2007-08-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For hugepage mappings, the file offset, like the address and size, needs to be aligned to the size of a hugepage. In commit 68589bc353037f233fe510ad9ff432338c95db66, the check for this was moved into prepare_hugepage_range() along with the address and size checks. But since BenH's rework of the get_unmapped_area() paths leading up to commit 4b1d89290b62bb2db476c94c82cf7442aab440c8, prepare_hugepage_range() is only called for MAP_FIXED mappings, not for other mappings. This means we're no longer ever checking for an aligned offset - I've confirmed that mmap() will (apparently) succeed with a misaligned offset on both powerpc and i386 at least. This patch restores the check, removing it from prepare_hugepage_range() and putting it back into hugetlbfs_file_mmap(). I'm putting it there, rather than in the get_unmapped_area() path so it only needs to go in one place, than separately in the half-dozen or so arch-specific implementations of hugetlb_get_unmapped_area().

* [SPARC64]: Fix several bugs in MSI handling.David S. Miller2007-08-31
| | | | | | | | | | | | | | | | | | | | | 1) sun4{u,v}_build_msi() have improper return value handling. We should always return negative error codes, instead of using the magic value "0" which could in fact be a valid MSI number. 2) sun4{u,v}_build_msi() should return -ENOMEM instead of calling prom_prom() halt with kzalloc() of the interrupt data fails. 3) We 'remembered' the MSI number using a singleton in the struct device archdata area, this doesn't work for MSI-X which can cause multiple MSIs assosciated with one device. Delete that archdata member, and instead store the MSI number in the IRQ chip data area. Signed-off-by: David S. Miller <davem@davemloft.net>

* [SPARC64]: Fix memory leak when cpu hotplugging.David S. Miller2007-08-08
| | | | | | | | | | | Every time a cpu is added via hotplug, we allocate the per-cpu MONDO queues but we never free them up. Freeing isn't easy since the first cpu gets this memory from bootmem.

* [SPARC64]: Fix conflicts in SBUS/PCI/EBUS/ISA DMA handling.David S. Miller2007-07-30
| | | | | | | | | | | | | | | | | | | Fully unify all of the DMA ops so that subordinate bus types to the DMA operation providers (such as ebus, isa, of_device) can work transparently. Basically, we just make sure that for every system device we create, the dev->archdata 'iommu' and 'stc' fields are filled in. Then we have two platform variants of the DMA ops, one for SUN4U which actually programs the real hardware, and one for SUN4V which makes hypervisor calls. This also fixes the crashes in parport_pc on sparc64, reported by Meelis Roos. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | We can't mark the whole thing init because there are dependencies in bootloaders that assume that _start, or whatever the image entry value, is 2 instructions before the "HdrS" signature. In fact, TILO assumes this entry is always at 0x4000, yikes! Also, right after the bootloader info area there are OBP strings and values that get used later in the boot process, and those are not all provably .init yet. Signed-off-by: David S.

* [SPARC]: Fix serial console device detection.David S. Miller2007-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | The current scheme works on static interpretation of text names, which is wrong. The output-device setting, for example, must be resolved via an alias or similar to a full path name to the console device. Paths also contain an optional set of 'options', which starts with a colon at the end of the path. The option area is used to specify which of two serial ports ('a' or 'b') the path refers to when a device node drives multiple ports. 'a' is assumed if the option specification is missing. This was caught by the UltraSPARC-T1 simulator. The 'output-device' property was set to 'ttya' and we didn't pick upon the fact that this is an OBP alias set to '/virtual-devices/console'. Instead we saw it as the first serial console device, instead of the hypervisor console. The infrastructure is now there to take advantage of this to resolve the console correctly even in multi-head situations in fbcon too. Thanks to Greg Onufer for the bug report.

* | [SPARC64]: Fix two year old bug in early bootup asm.David S. Miller2007-07-20
| | | | | | | | | | | | | | | | | | We try to fetch the CIF entry pointer from %o4, but that can get clobbered by the early OBP calls. It is saved in %l7 already, so actually this "mov %o4, %l7" can just be completely removed with no other changes. Signed-off-by: David S. Miller <davem@davemloft.net>
