This is an updated patchset for megasas. Upon popular demand
I've split it into three parts, the header file, the emulation
itself, and a patch adding trace events to the emulation.
Changes since v16:
- Codingstyle fixes, reported by Alex Graf
Changes since v15:
- Move to new SCSI API
- Use generic trace functions for DCMDs
- Replace bitfields with defines
- Implement CFG_READ
- Fix enclosure ID reporting
Changes since v14:
- Rename MPTState to MegasasState
- Use bool type
- Enable 64 bit PCI accesses
- Replace raid mode string handling
- Use common function for requests handling
Changes since v13:
- Remove separate MSI-X BAR
- Simplify BAR allocation
Changes since v12:
- Fixup flag setting via properties
- Fixup MSI-X handling
- Disable MSI-X per default
Changes since v11:
- Remove unneeded variables
Changes since v10:
- Port to new device type API
- Include suggestion from Alex Graf:
- Remove 'inline' function declaration
- Queue setup and interrupt enablement needs to be treated
independently
- Always read in 64 bit context and just mask out the top
bits if required
Changes since v9:
- Split off trace events into a separate patch
- Do not check for max_luns in PD Info
- Update trace events
- Clarify license statement
- Fixup coding style issues
Changes since v8:
- Remove 'disable' keyword from trace definitions
- Convert hand-crafted debugging statements with trace
definitions
- Treat 'context' tag as little endian
Changes since v7:
- Port to new memory API
- Port to new PCI infrastructure
- Use fixed buffers for sense processing
- Update to updated SCSI infrastructure
Changes since v6:
- Preliminary patches pushed to Kevins block tree
- Implement 64bit contexts, required for Windows7
- Use iovecs for DCMD processing
- Add MSI-X support
Latest Linux driver now happily uses MSI-X.
- Static iovec allocation
We have a fixed upper number of iovecs, so we can
save us the allocation. Suggested by Alex Graf.
- Update MFI header
Latest Linux driver has some more definitions,
add them
- Fixup AEN handling
- Update tracing details
- Remove sdev pointer from megasas_cmd_t
Changes since v5:
- megasas: Use tracing infrastructure instead of DPRINTF
- megasas: Use new PCI infrastructure
- megasas: Check for iovec mapping failure
cpu_map_physical_memory() might fail, so we need to check for
it when mapping iovecs.
- megasas: Trace scsi buffer overflow
The transfer length as specified in the SCSI command might
disagree with the length of the iovec. We should be tracing
these issues.
- megasas: Reset frames after init firmware
When receiving an INIT FIRMWARE command we need reset all
frames, otherwise some frames might point to invalid memory.
Chances since v4:
- megasas: checkpatch.pl fixes and update to work with the
changed interface in scsi_req_new(). Also included the
suggested fixes from Alex.
Hannes Reinecke (3):
