* serial: define FIXED_PORT flag for serial_coreDavid Gibson2007-05-071-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | At present, the serial core always allows setserial in userspace to change the port address, irq and base clock of any serial port. That makes sense for legacy ISA ports, but not for (say) embedded ns16550 compatible serial ports at peculiar addresses. In these cases, the kernel code configuring the ports must know exactly where they are, and their clocking arrangements (which can be unusual on embedded boards). It doesn't make sense for userspace to change these settings. Therefore, this patch defines a UPF_FIXED_PORT flag for the uart_port structure. If this flag is set when the serial port is configured, any attempts to alter the port's type, io address, irq or base clock with setserial are ignored. In addition this patch uses the new flag for on-chip serial ports probed in arch/powerpc/kernel/legacy_serial.c, and for other hard-wired serial ports probed by drivers/serial/of_serial.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o __pa() should be used only on kernel linearly mapped virtual addresses and not on kernel text and data addresses. o Hibernation code needs to determine the physical address associated with kernel symbol to mark a section boundary which contains pages which don't have to be saved and restored during hibernate/resume operation. o Move this piece of code in arch dependent section. So that architectures which don't have kernel text/data mapped into kernel linearly mapped region can come up with their own ways of determining physical addresses associated with a kernel text.

* | [POWERPC] ibmebus: change probe/remove interface from using loc-code to DT pathJoachim Fenkes2007-04-131-55/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases, multiple OFDT nodes might share the same location code, so the location code is not a unique identifier for an OFDT node. Changed the ibmebus probe/remove interface to use the DT path of the device node instead of the location code. The DT path must be written into probe/remove right as it would appear in the "devspec" attribute of the ebus device: relative to the DT root, with a leading slash and without a trailing slash. One trailing newline will not hurt; multiple newlines will (like perl's chomp()). Example: Add a device "/proc/device-tree/foo@12345678" to ibmebus like this: echo /foo@12345678 > /sys/bus/ibmebus/probe Remove the device like this: echo /foo@12345678 > /sys/bus/ibmebus/remove Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* | [POWERPC] Make tlb flush batch use lazy MMU modeBenjamin Herrenschmidt2007-04-132-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current tlb flush code on powerpc 64 bits has a subtle race since we lost the page table lock due to the possible faulting in of new PTEs after a previous one has been removed but before the corresponding hash entry has been evicted, which can leads to all sort of fatal problems. This patch reworks the batch code completely. It doesn't use the mmu_gather stuff anymore. Instead, we use the lazy mmu hooks that were added by the paravirt code. They have the nice property that the enter/leave lazy mmu mode pair is always fully contained by the PTE lock for a given range of PTEs. Thus we can guarantee that all batches are flushed on a given CPU before it drops that lock. We also generalize batching for any PTE update that require a flush. Batching is now enabled on a CPU by arch_enter_lazy_mmu_mode() and disabled by arch_leave_lazy_mmu_mode(). The code epects that this is always contained within a PTE lock section so no preemption can happen and no PTE insertion in that range from another CPU. When batching is enabled on a CPU, every PTE updates that need a hash flush will use the batch for that flush.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are many adapters which cannot handle DMAing across any 4 GB boundary. For instance, the latest Emulex adapters. This normally is not an issue as firmware gives dma-windows under 4gigs. However, some of the new System-P boxes have dma-windows above 4gigs, and this present a problem. During initialization of the IOMMU tables, the last entry at each 4GB boundary is marked as used. Thus no mappings can cross the boundary. If a table ends at a 4GB boundary, the entry is not marked as used. A boot option to remove this 4GB protection is given w/ protect4gb=off. This exposes the potential issue for driver and hardware development purposes.
