* [IA64] Add mapping table between irq and vectorYasuaki Ishimatsu2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | Add mapping tables between irqs and vectors, and its management code. This is necessary for supporting multiple vector domain because 1:1 mapping between irq and vector will be changed to n:1. The irq == vector relationship between irqs and vectors is explicitly remained for percpu interrupts, platform interrupts, isa IRQs and vectors assigned using assign_irq_vector() because some programs might depend on it. And I should consider the following problem. When pci drivers enabled/disabled devices dynamically, its irq number is changed to the different one. Therefore, suspend/resume code may happen problem. To fix this problem, I bound gsi to irq.

| | * [POWERPC] Make the debugfs "powerpc" dir globally accessibleMichael Ellerman2007-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The prom.c debugging code creates a "powerpc" directory in debugfs, which is nice, but doesn't allow any other debugging code to stick things under "powerpc" in debugfs.

| | * [POWERPC] Add a warning to help trackdown device_node refcounting bugsMichael Ellerman2007-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the refcount for a device node goes to 0, we call the destructor - of_node_release(). This should only happen if we've already detached the node from the device tree. So add a flag OF_DETACHED which tracks detached-ness, and if we find ourselves in of_node_release() without it set, issue a warning and don't free the device_node. To avoid warning continuously reinitialise the kref to a sane value. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

To cope with the code that should be hooked inside driver, but is really board specific (like set_voltage), global structure mpc8xx_pcmcia_ops holds necessary function pointers that are filled in the BSP code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Freescale PCI-e controllers have an issue in that they use the PCI_PRIMARY_BUS register in the virtual P2P bridge to determine which bus number to match on when generating a type 0 config cycle. The issue is if we are renumbering bus numbers to match Linux we will try setting the PCI_PRIMARY_BUS and will not know which bus number to use for generating type 0 config cycles. We surpress writing the register in the P2P bridge and always keep it at zero. In the future when proper PCI domain support is working we should be able to remove this.

It seems the reason for doing this is to ensure a resaonable time delta after time_init(). On current kernels (with udev), this call is made 40-60 seconds into the boot process, by moving it to a late initcall it is called approximately 5 seconds after time_init() is called.

| | * [POWERPC] Fix Kexec/Kdump for power6Sachin P. Sant2007-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Power machines supporting VRMA, Kexec/Kdump does not work. VRMA (virtual real-mode area) means that accesses with IR/DR = 0 (i.e. the MMU "off") actually still go through the hash table, using entries put there by the hypervisor. This means that when we clear out the hash table on kexec, we need to make sure these entries are left untouched. This also adds plpar_pte_read_raw() on the lines of plpar_pte_remove_raw().

| | * [POWERPC] Fix stolen time for SMT without LPARMichael Neuling2007-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For POWERPC, stolen time accounts for cycles lost to the hypervisor or PURR cycles attributed to the other SMT thread. Hence, when a PURR is available, we should still calculate stolen time, irrespective of being virtualised.

| | * [POWERPC] Add irq_create_direct_mapping()Michael Ellerman2007-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds irq_create_direct_mapping(). This routine is an alternative to irq_create_mapping(), for irq controllers that can use linux virq numbers directly as hardware numbers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Uninline virq_to_hw and export it so modules can use it. The alternative would be to export the irq_map array instead, but it's an infrequently called function, and keeping the array unexported seems considerably cleaner.

| | * [POWERPC] Merge CPU features pertaining to icache coherencyDavid Gibson2007-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the powerpc kernel has a 64-bit only feature, COHERENT_ICACHE used for those CPUS which maintain icache/dcache coherency in hardware (POWER5, essentially). It also has a feature, SPLIT_ID_CACHE, which is used on CPUs which have separate i and d-caches, which is to say everything except 601 and Freescale E200. In nearly all the places we check the SPLIT_ID_CACHE, what we actually care about is whether the i and d-caches are coherent (which they will be, trivially, if they're the same cache). This tries to clarify the situation a little. The COHERENT_ICACHE feature becomes availble on 32-bit and is set for all CPUs where i and d-cache are effectively coherent, whether this is due to special logic (POWER5) or because they're unified. We check this, instead of SPLIT_ID_CACHE nearly everywhere. The SPLIT_ID_CACHE feature itself is replaced by a UNIFIED_ID_CACHE feature with reversed sense, set only on 601 and Freescale E200. In the two places (one Freescale BookE specific) where we really care whether it's a unified cache, not whether they're coherent, we check this feature. The CPUs with unified cache are so few, we could consider replacing this feature bit with explicit checks against the PVR. This will make unifying the 32-bit and 64-bit cache flush code a little more straightforward. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
