This adds struct device argument to sba_alloc_range and ccio_alloc_range, a preparation for modifications to fix the IOMMU segment boundary problem. This change enables ccio_alloc_range to access to LLD's segment boundary limits.

Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

This means "DMA Read returns" can bypass "MMIO Writes". Violating the PCI specs in this case improves outbound DMA "flows" and is currently not required by any drivers. This is NOT a new behavior. Previous chipsets did this already and I believe ZX1 PDC was already setting this for hpux. I just want to further document the behavior.

Signed-off-by: NGrant Grundler <grundler@parisc-linux.org> 2.6.14-rc2-pa3 move "sync" outside the main loop that fills IO Pdir. Signed-off-by: NGrant Grundler <grundler@parisc-linux.org> remove explicit use of sr0 in fdc ops. Thanks to Joel Soete for reminding me were I added those... Signed-off-by: NGrant Grundler <grundler@parisc-linux.org> 2.6.14-rc2-pa2 - make SBA more anal about invalidating pdir entries Previous code cleared the valid flag a pdir entry but it did NOT guarantee this change was visible to the PDIR before writing the PCOM register. Ie the SBA could pick up a stale entry if the write happened to hit the SBA before the cacheline was flushed from the cache. Long term, I think I want to make this a compile time flag. Developement tree should enable anal pdir checking by default and Debian can disable it with either a CONFIG option or one-line patch. fdc/sync options can only negatively affect performance though I haven't measure how much yet. If someone can run netperf TCP_RR across gige and compare -pa1 and -pa2, that would be sufficient. Cleaned up the use of "fdc" to make sure it's using "kernel" space id (specify sr0 but maps to sr4-7). It seems a bit fragile to assume "sr1" gets loaded with KERNEL_SPACE which is how the code works today. Tested on 32 and 64-bit SMP kernels on j6k. Signed-off-by: NGrant Grundler <grundler@parisc-linux.org> remove PDC_NARROW from SBA and document history of PDC_NARROW a bit. It will still show up in an older kernel's .config file.

Signed-off-by: NGrant Grundler <grundler@parisc-linux.org> 2.6.12-rc4-pa2 fix 32-bit support for Astro platforms o Since my last SBA code change, SBA could allocate more than 1GB of IOVA space on Astro boxes with more than 1GB of RAM when running 32-bit kernel. This is bad since IOMMU can only talk to the first 1GB at most. Kudos to jejb for quickly spotting that bug. o jejb also noted SBA should *always* reject DMA masks > 32-bits since DMA-mapping.txt indicates caller should try again with 32-bits. o off-by-one error when comparing the mask to IOVA space size.

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!
