* x86: use NR_IRQS_LEGACY to replace 16Yinghai Lu2009-02-092-7/+5
| | | | | | | | | Impact: cleanup also could kill platform_legacy_irq Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | Impact: make nr_irqs depend more on cards used in a system depend on nr_irq_gsi more, and have a ratio for MSI. v2: make nr_irqs less than NR_VECTORS * nr_cpu_ids aka if only one cpu, we only can support nr_irqs = NR_VECTORS Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to recurring issues with DMAR support on certain platforms. There's a number of filesystem corruption incidents reported: https://bugzilla.redhat.com/show_bug.cgi?id=479996 http://bugzilla.kernel.org/show_bug.cgi?id=12578 Provide a Kconfig option to change whether it is enabled by default. If disabled, it can still be reenabled by passing intel_iommu=on to the kernel. Keep the .config option off by default.

| * x86: don't apply __supported_pte_mask to non-present ptesJeremy Fitzhardinge2009-02-052-7/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On an x86 system which doesn't support global mappings, __supported_pte_mask has _PAGE_GLOBAL clear, to make sure it never appears in the PTE. pfn_pte() and so on will enforce it with: static inline pte_t pfn_pte(unsigned long page_nr, pgprot_t pgprot) { return __pte((((phys_addr_t)page_nr << PAGE_SHIFT) | pgprot_val(pgprot)) & __supported_pte_mask); } However, we overload _PAGE_GLOBAL with _PAGE_PROTNONE on non-present ptes to distinguish them from swap entries. However, applying __supported_pte_mask indiscriminately will clear the bit and corrupt the pte. I guess the best fix is to only apply __supported_pte_mask to present ptes. This seems like the right solution to me, as it means we can completely ignore the issue of overlaps between the present pte bits and the non-present pte-as-swap entry use of the bits. __supported_pte_mask contains the set of flags we support on the current hardware. We also use bits in the pte for things like logically present ptes with no permissions, and swap entries for swapped out pages. We should only apply __supported_pte_mask to present ptes, because otherwise we may destroy other information being stored in the ptes.

Without this patch, the memory window BAR is left at whatever value happened to be loaded into the BAR when Linux was booted. Without this patch, memory could end up getting mapped at any of the 1G address boundaries instead of at '0' where Linux expects it. Similarly, this patch also ensures that the internally memory mapped registers (IMMR) are mapped to the correct PCI address range. Without this patch, PCI appears to work correctly until a PCI device is inserted which DMAs into memory.

The later two calls to rb532_gpio_set_{ilevel,istat}() are implicitly being done by the IRQ initialisation of pata-rb532-cf.

The mapped GPIOs support triggering on either level high or low. To achieve this, the set_type() function calls rb532_gpio_set_ilevel() for interrupts of the above mentioned group. As there is no way to alter the triggering characteristics of the other interrupts, accept level triggering on status high only. (This is just a guess; but as the system boots fine and interrupt-driven devices (e.g. serial console) work with no implications, it seems to be right.) To clear a GPIO mapped IRQ, the source has to be cleared (i.e., the interrupt status bit of the corresponding GPIO pin). This is done inside rb532_disable_irq(). After applying these changes I could undo most of my former "fixes" to pata-rb532-cf. Particularly all interrupt handling can be done generically via set_irq_type() as it was before.
