* [POWERPC] Fix PowerPC 750CL and 750GX CPU featuresJosh Boyer2007-04-241-2/+2
| | | | | | | | | | | PowerPC 750CL has high BATs. The patch below adds a CPU_FTRS_750CL that includes that. Without it, the original firmware mappings in the high BATs aren't cleared which continue to override the linux translations. It also adds CPU_FTR_COMMON to CPU_FTRS_750GX for completeness.

* [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.

* [POWERPC] DMA 4GB boundary protectionJake Moilanen2007-04-131-1/+34
| | | | | | | | | | | | | | | | | | | | | 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.

* | [POWERPC] ibmebus: dynamic addition/removal of adapters, some code cleanupJoachim Fenkes2007-03-161-34/+133
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds two sysfs attributes to /sys/bus/ibmebus which can be used to notify the ebus driver of added / removed ebus devices in the OF device tree. Echoing the device's location code (as found in the OFDT "ibm,loc-code" property) into the "probe" attribute will notify ebus of addition of the device and cause the appropriate device driver's probe function to be called on the device. Likewise, echoing the location code into the "remove" attribute will cause the device to be removed from the system. The writes will block until the respective operation has finished and return an error code if the operation failed. In addition, two minor tidbits are fixed: - The fake root device used to provide a common parent for all ebus devices is now based on device instead of of_device - it had no associated devtree node. This saves several checks throughout the ebus driver. - The sysfs attributes are now generated automagically by device_register() instead of by the ibmebus code, which saves a few compiler warnings about unused return codes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present, when an initrd is passed to the kernel used flat device tree properties, the memory the initrd occupies must also be reserved in the flat tree's reserve map, or the kernel may overwrite it. That makes life more complicated than it could be for the bootwrapper. This patch makes the kernel automatically reserve the initrd's space. That in turn requires parsing the initrd parameters earlier than they are currently, in early_init_dt_scan_chosen() instead of check_for_initrd().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present calling lmb_reserve() (and hence lmb_add_region()) twice for exactly the same memory region will cause strange behaviour. This makes life difficult when booting from a flat device tree with memory reserve map. Which regions are automatically reserved by the kernel has changed over time, so it's quite possible a newer kernel could attempt to auto-reserve a region which is also explicitly listed in the device tree's reserve map, leading to trouble. This patch avoids the problem by making lmb_reserve() ignore a call to reserve a previously reserved region. It also removes a now redundant test designed to avoid one specific case of the problem noted above. At present, this patch deals only with duplicate reservations of an identical region. Attempting to reserve two different, but overlapping regions will still cause problems. I might post another patch later dealing with this case, but I'm avoiding it now since it is substantially more complicated to deal with, less likely to occur and more likely to indicate a genuine bug elsewhere if it does occur.

* [PATCH] msi: sanely support hardware level msi disablingEric W. Biederman2007-03-051-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases when we are not using msi we need a way to ensure that the hardware does not have an msi capability enabled. Currently the code has been calling disable_msi_mode to try and achieve that. However disable_msi_mode has several other side effects and is only available when msi support is compiled in so it isn't really appropriate. Instead this patch implements pci_msi_off which disables all msi and msix capabilities unconditionally with no additional side effects. pci_disable_device was redundantly clearing the bus master enable flag and clearing the msi enable bit. A device that is not allowed to perform bus mastering operations cannot generate intx or msi interrupt messages as those are essentially a special case of dma, and require bus mastering. So the call in pci_disable_device to disable msi capabilities was redundant. quirk_pcie_pxh also called disable_msi_mode and is updated to use pci_msi_off. Signed-off-by: Eric W.

Therefore add a global mutex to take care of serialisation for everyone, once and for all. Locking for get_brightness remains optional since most users don't need it.

| * Storage class should be before const qualifierTobias Klauser2007-02-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | The C99 specification states in section 6.11.5: The placement of a storage-class specifier other than at the beginning of the declaration specifiers in a declaration is an obsolescent feature.

* | [POWERPC] add of_get_mac_address and update fsl_soc.c to use itTimur Tabi2007-02-171-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add function of_get_mac_address(), which obtains the best MAC address to use from the device tree by checking various properties in order. The order is: 'mac-address', then 'local-mac-address', then 'address'. It skips properties that contain invalid MAC addresses, which were probably not initialized by U-Boot. Update gfar_of_init() and fs_enet_of_init() in fsl_soc.c to call of_get_mac_address(). Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
