2005-05-25[PATCH] IB: fix endianness of path record MTU fieldRoland Dreier
Make MTU field in SA PathRecord and MCMemberRecord a u8 rather than an enum to avoid complications with endianness. Signed-off-by: Roland Dreier <roland@topspin.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-05-25[PATCH] IB: allow NULL sa_query callbacksRoland Dreier
Check if a client passes a NULL callback into an SA query, and if so, never call back. This fixes an oops if someone unloads ib_ipoib and ib_sa in rapid succession. ib_ipoib does an MCMember delete with a NULL callback and 0 timeout on unload, which is usually fine since the delete completes successfully. However, if ib_sa is unloaded immediately afterwards, the delete will be canceled and ib_sa will try to call the (now already unloaded) ib_ipoib module back with the cancel completion, which triggers the oops.

2005-04-16[PATCH] IB/mthca: add support for new MT25204 HCARoland Dreier
Decouple table of HCA features from exact HCA device type. Add a current FW version field so we can warn when someone is using old FW. Add support for new MT25204 HCA. Remove the warning about mem-free support, since it should be pretty solid at this point.

2005-04-16[PATCH] IB/mthca: add fast memory region implementationMichael S. Tsirkin
Implement fast memory regions (FMRs), where the driver writes directly into the HCA's translation tables rather than requiring a firmware command. For Tavor, MTTs for FMR are separate from regular MTTs, and are reserved at driver initialization. This is done to limit the amount of virtual memory needed to map the MTTs. For Arbel, there's no such limitation, and all MTTs and MPTs may be used for FMR or for regular MR. Signed-off-by: Michael S.

2005-04-16[PATCH] IB/mthca: fix MTT allocation in mem-free modeRoland Dreier
Fix bug in MTT allocation in mem-free mode. I misunderstood the MTT size value returned by the firmware -- it is really the size of a single MTT entry, since mem-free mode does not segment the MTT as the original firmware did. This meant that our MTT addresses ended up being off by a factor of 8. This meant that our MTT allocations might overlap, and so we could overwrite and corrupt earlier memory regions when writing new MTT entries. We fix this by always using our 64-byte MTT segment size. This allows some simplification of the code as well, since there's no reason to put the MTT segment size in a variable -- we can always use our enum value directly.

Correct and simplify calculation of static rate. We need to round up the quotient of (local_rate - path_rate) / path_rate.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
