2006-04-10IB: simplify static rate encodingJack Morgenstein
Push translation of static rate to HCA format into low-level drivers, where it belongs. For static rate encoding, use encoding of rate field from IB standard PathRecord, with addition of value 0, for backwards compatibility with current usage. The changes are: - Add enum ib_rate to midlayer includes. - Get rid of static rate translation in IPoIB; just use static rate directly from Path and MulticastGroup records. - Update mthca driver to translate absolute static rate into the format used by hardware. This also fixes mthca's static rate handling for HCAs that are capable of 4X DDR. Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-04-02IB/mthca: Always build debugging code unless CONFIG_EMBEDDED=yRoland Dreier
Change the mthca debugging trace output code so that it can enabled and disabled at runtime with the debug_level module parameter in sysfs. Also, don't allow CONFIG_INFINIBAND_MTHCA_DEBUG to be disabled unless CONFIG_EMBEDDED is selected. We want users (and especially distros) to have this turned on unless they really need to save space, because by the time we want debugging output, it's usually too late to rebuild a kernel.

2006-03-20IB/mthca: Optimize large messages on Sinai HCAsEli Cohen
Sinai (one-port PCI Express) HCAs get improved throughput for messages bigger than 80 KB in DDR mode if memory keys are formatted in a specific way. The enhancement only works if the memory key table is smaller than 2^24 entries. For larger tables, the enhancement is off and a warning is printed (to avoid silent performance loss).

2006-01-30IB/mthca: Relax UAR size checkMichael S. Tsirkin
There are some cards around that have UAR (user access region) size different from 8 MB.

2005-11-10[IB] uverbs: have kernel return QP capabilitiesJack Morgenstein
Move the computation of QP capabilities (max scatter/gather entries, max inline data, etc) into the kernel, and have the uverbs module return the values as part of the create QP response. This keeps precise knowledge of device limits in the low-level kernel driver. This requires an ABI bump, so while we're making changes, get rid of the max_sge parameter for the modify SRQ command -- it's not used and shouldn't be there.

2005-11-02[IB] mthca: fix format of FW versionRoland Dreier
Mellanox has decided that the components of the firmware version are really meant to be displayed in decimal, e.g. 0x000400070190 is version 4.7.400. Change the format we use from "%x.%x.%x" to "%d.%d.%d" to match this convention. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2005-08-26[PATCH] IB/mthca: Use correct port width capability valueRoland Dreier
When we call the INIT_IB firmware command to bring up a port, use the actual port width capability returned by the QUERY_DEV_LIM command instead of always trying to enable both 1X and 4X. This fixes breakage seen when the firmware is build to allow 4X only. Signed-off-by: Roland Dreier <rolandd@cisco.com>

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.

2005-04-16Linux-2.6.12-rc2v2.6.12-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!
