* [POWERPC] zImage: Cleanup and improve zImage entry pointDavid Gibson2007-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch re-organises the way the zImage wrapper code is entered, to allow more flexibility on platforms with unusual entry conditions. After this patch, a platform .o file has two options: 1) It can define a _zimage_start, in which case the platform code gets control from the very beginning of execution. In this case the platform code is responsible for relocating the zImage if necessary, clearing the BSS, performing any platform specific initialization, and finally calling start() to load and enter the kernel. 2) It can define platform_init(). In this case the generic crt0.S handles initial entry, and calls platform_init() before calling start(). The signature of platform_init() is changed, however, to take up to 5 parameters (in r3..r7) as they come from the platform's initial loader, instead of a fixed set of parameters based on OF's usage. When using the generic crt0.S, the platform .o can optionally supply a custom stack to use, using the BSS_STACK() macro. If this is not supplied, the crt0.S will assume that the loader has supplied a usable stack. In either case, the platform code communicates information to the generic code (specifically, a PROM pointer for OF systems, and/or an initrd image address supplied by the bootloader) via a global structure "loader_info". In addition the wrapper script is rearranged to ensure that the platform .o is always linked first. This means that platforms where the zImage entry point is at a fixed address or offset, rather than being encoded in the binary header can be supported using option (1).

* [POWERPC] zImage: Cleanup and improve prep_kernel()David Gibson2007-03-12
| | | | | | | | | | | | | | | | | | | | | | | This patch rewrites prep_kernel() in the zImage wrapper code to be clearer and more flexible. Notable changes: - Handling of the initrd image from prep_kernel() has moved into a new prep_initrd() function. - The address of the initrd image is now added as device tree properties, as the kernel expects. - We only copy a packaged initrd image to a new location if it is in danger of being clobbered when the kernel moves to its final location, instead of always. - By default we decompress the kernel directly to address 0, instead of requiring it to relocate itself. Platforms (such as OF) where doing this could clobber still-live firmware data structures can override the vmlinux_alloc hook to provide an alternate place to decompress the kernel. - We no longer pass lots of information between functions in global variables.

* [POWERPC] zImage: Add more flexible gunzip convenience functionsDavid Gibson2007-03-12
| | | | | | | | | | | | | | | | | | | | | | | At present, arch/powerpc/boot/main.c includes a gunzip() function which is a convenient wrapper around zlib. However, it doesn't conveniently allow decompressing part of an image to one location, then the remainder to a different address. This patch adds a new set of more flexible convenience wrappers around zlib, moving them to their own file, gunzip_util.c, in the process. These wrappers allow decompressing sections of the compressed image to different locations. In addition, they transparently handle uncompressed data, avoiding special case code to handle uncompressed vmlinux images. The patch also converts main.c to use the new wrappers, using the new flexibility to avoid decompressing the vmlinux's ELF header twice as we did previously. That in turn means we avoid extending our allocations for the vmlinux to allow space for the extra copy of the ELF header.

* [POWERPC] DMA 4GB boundary protectionJake Moilanen2007-03-08
| | | | | | | | | | | | | | | | | | | | There are many adapters which can not handle DMAing acrosss any 4 GB boundary. For instance the latest Emulex adapters. This normally is not an issue as firmware gives us dma-windows under 4gigs. However, some of the new System-P boxes have dma-windows above 4gigs, and this present a problem. I propose fixing it in the IOMMU allocation instead of making each driver protect against it as it is more efficient, and won't require changing every driver which has not considered this issue. This patch checks to see if the mapping spans a 4 gig boundary, and if it does, retries the allocation. It tries the next allocation at the start of the crossed 4 gig boundary.

* [POWERPC] Automatically lmb_reserve() initrdDavid Gibson2007-03-07
| | | | | | | | | | | | | | | 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().

* [POWERPC] Allow duplicate lmb_reserve() callsDavid Gibson2007-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [POWERPC] Harden validate_sp against stack corruptionPaul Mackerras2007-03-07
| | | | | | | | | | | | | | If something has overflowed or corrupted the stack and causes an oops, and we try to print a stack trace, that will call validate_sp, which can itself cause an oops if the cpu field of the thread_info struct at the bottom of the stack has been corrupted (if CONFIG_IRQSTACKS is set). This makes debugging harder. To avoid the second oops, this adds a check to make sure that the cpu number is reasonable before using it to check whether the stack is on the softirq or hardirq stack.

The old functions made wrong assumptions about kernel and user space when the kernel and user address spaces are switched (kernel in home space, user in primary/secondary space). Secondly the user process can switch to the accress register mode if it is running in primary or secondary mode. In addition it can load an arbitrary value to the access registers. If any other value than 0 for primary space or 1 for secondary space is loaded and memory is accessed using the base register related to the access register, the program should be terminated with a SIGSEGV. To achieve that the DUALD pointer in the DUCT and the PSALD pointer in the PASTE need to point to an array of 8 invalid access-list entries to get a ALEN-translation exception if an invalid alet is used.

The memory area for this header is also marked as a separate EFI memory descriptor on ia64. The separate EFI memory descriptor is at the moment of the type EFI_UNUSABLE_MEMORY. With such a type the secondary kernel skips over the entire memory granule (config option, 16M or 64M) when detecting memory. If we are lucky we will just lose some memory, but if we happen to have data in the same granule (such as an initramfs image), then this data will never get mapped and the kernel bombs out when trying to access it. So this is an attempt to fix this by changing the EFI memory descriptor type into EFI_LOADER_DATA. This type is the same type used for the kernel data and for initramfs. In the secondary kernel we then handle the ELF core header data the same way as we handle the initramfs image. This patch contains the kernel changes to make this happen. Pretty straightforward, we reserve the area in reserve_memory(). The address for the area comes from the kernel command line and the size comes from the specialized EFI parsing function vmcore_find_descriptor_size().
