2007-04-13[POWERPC] Allow drivers to map individual 4k pages to userspacePaul Mackerras4-14/+42
Some drivers have resources that they want to be able to map into userspace that are 4k in size. On a kernel configured with 64k pages we currently end up mapping the 4k we want plus another 60k of physical address space, which could contain anything. This can introduce security problems, for example in the case of an infiniband adaptor where the other 60k could contain registers that some other program is using for its communications. This patch adds a new function, remap_4k_pfn, which drivers can use to map a single 4k page to userspace regardless of whether the kernel is using a 4k or a 64k page size. Like remap_pfn_range, it would typically be called in a driver's mmap function. It only maps a single 4k page, which on a 64k page kernel appears replicated 16 times throughout a 64k page. On a 4k page kernel it reduces to a call to remap_pfn_range. The way this works on a 64k kernel is that a new bit, _PAGE_4K_PFN, gets set on the linux PTE. This alters the way that __hash_page_4K computes the real address to put in the HPTE. The RPN field of the linux PTE becomes the 4k RPN directly rather than being interpreted as a 64k RPN. Since the RPN field is 32 bits, this means that physical addresses being mapped with remap_4k_pfn have to be below 2^44, i.e. 0x100000000000. The patch also factors out the code in arch/powerpc/mm/hash_utils_64.c that deals with demoting a process to use 4k pages into one function that gets called in the various different places where we need to do that. There were some discrepancies between exactly what was done in the various places, such as a call to spu_flush_all_slbs in one case but not in others. Signed-off-by: Paul Mackerras <paulus@samba.org>

2007-04-13[POWERPC] Clean up zImage handling of the command lineDavid Gibson2-33/+21
This cleans up how the zImage code manipulates the kernel command line. Notable improvements from the old handling: - Command line manipulation is consolidated into a new prep_cmdline() function, rather than being scattered across start() and some helper functions - Less stack space use: we use just a single global command line buffer, which can be initialized by an external tool as before, we no longer need another command line sized buffer on the stack. - Easier to support platforms whose firmware passes a commandline, but not a device tree. Platform code can now point new loader_info fields to the firmware's command line, rather than having to do early manipulation of the /chosen bootargs property which may then be rewritten again by the core.

2007-04-13[POWERPC] Add device tree utility functions to zImageDavid Gibson4-17/+136
This patch adds a library of useful device tree manipulation functions to the zImage library, for use by platform code. These functions are based on the hooks already in dt_ops, so they're not dependent on a particular device tree implementation. This patch also slightly streamlines the code in main.c using these new functions. This is a consolidation of my work in this area with Scott Wood's patches to a very similar end.

2007-04-13[POWERPC] DMA 4GB boundary protectionJake Moilanen1-1/+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.

There is one significant difference between the behavior of root hubs (as embodied in host controller hardware) and external hubs: When a remote-wakeup signal is received, an external hub sends an interrupt message at the _end_ of the resume sequence but a root hub generates and interrupt at the _beginning_ of the resume sequence. The host system must poll for the end of the sequence. When ehci-hcd was converted to interrupt-driven operation instead of using polling, the remaining need for this particular poll was overlooked.
