| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The simscsi code at present overflows an int if it's given a large disk image. The attached patch increases the possible size to 128G. While it's unlikely that anyone will want to use SKI with such a large drive, the same framework is currently being used for various virtualisation experiments.

| | * [IA64] more robust zx1/sx1000 machvec supportAlex Williamson2005-09-142-15/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Machine vector selection has always been a bit of a hack given how early in system boot it needs to be done. Services like ACPI namespace are not available and there are non-trivial problems to moving them to early boot. However, there's no reason we can't change to a different machvec later in boot when the services we need are available. By adding a entry point for later initialization of the swiotlb, we can add an error path for the hpzx1 machevec initialization and fall back to the DIG machine vector if IOMMU hardware isn't found in the system. Since ia64 uses 4GB for zone DMA (no ISA support), it's trivial to allocate a contiguous range from the slab for bounce buffer usage.

* / [IA64] Fix simscsi for new SCSI midlayerPeter Chubb2005-09-221-6/+23
|/ | | | | | | | | | | | | | | The sd driver now uses scsi_execute_req() for almost everything. scsi_execute_req() converts requests into scatterlists. Fix the HP SCSI disk simulator to understand scatterlists for more commands. Without this patch the current kernel will not boot on the simulator (the disks are always detected as having no sectors, and so cannot be mounted).

* [IA64] Fix simulator boot (for real this time).Peter Chubb2005-08-231-1/+1
| | | | | | | | | | | | Thanks to Stephane, we've now worked out the real cause of the `Linux will not boot on simulator' problem. Turns out it's a stack overflow because the stack pointer wasn't being initialised properly in boot_head.S (it was being initialised to the lowest instead of the highest address of the stack, so the first push started to overwrite data in the BSS).

* [IA64] Simulator bootloader fails with gcc 4Ian Wienand2005-08-181-1/+5
| | | | | | | | | | | | | | | | | | After building a fresh tree with gcc 4 I can't boot the simulator as the bootloader loader dies with loading /home/ianw/kerntest/kerncomp//build/sim_defconfig/vmlinux... failed to read phdr After some investigation I believe this is do with differences between the alignment of variables on the stack between gcc 3 and 4 and the ski simulator. If you trace through with the simulator you can see that the disk_stat structure value returned from the SSC_WAIT_COMPLETION call seems to be only half loaded. I guess it doesn't like the alignment of the input. Signed-off-by: Ian Wienand <ianw@gelato.unsw.edu.au> Signed-off-by: Tony Luck <tony.luck@intel.com>
* [IA64] assign_irq_vector() should not panicKenji Kaneshige2005-07-112-4/+9
| | | | | | | | | | | | | | | | | | Current assign_irq_vector() will panic if interrupt vectors is running out. But I think how to handle the case of lack of interrupt vectors should be handled by the caller of this function. For example, some PCI devices can raise the interrupt signal via both MSI and I/O APIC. So even if the driver for these device fails to allocate a vector for MSI, the driver still has a chance to use I/O APIC based interrupt. But currently there is no chance for these driver to use I/O APIC based interrupt because kernel will panic when assign_irq_vector() fails to allocate interrupt vector. The following patch changes assign_irq_vector() for ia64 to return -ENOSPC on error instead of panic (as i386 and x86_64 versions do).

* [IA64] sba_iommu bug fixesAlex Williamson2005-04-251-40/+56
| | | | | | | | | | | | | | | | | | | This fixes a couple of bugs in the zx1/sx1000 sba_iommu. These are all pretty low likelihood of hitting. The first problem is a simple off by one, deep in the sba_alloc_range() error path. Surrounding that was a lock ordering problem that could have potentially deadlocked with the order the locks are grabbed in sba_unmap_single(). I moved the resource locking into sba_search_bitmap() to prevent this. Finally, there's a potential race between unmapping pdir entries and marking incoming DMA pages clean. If you see any oddities, please let me know, but I've tested it pretty thoroughly here. Tony, please apply. Thanks, BTW, many of the options in this driver not on by default are becoming more and more broken. I'll be working on some patches to clean them out, but I wanted to get this bug fix out first.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-1623-0/+5404
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
