- Hardware Compatibility
- -----------------------
- This is an informal test summary. It is not definitive as a reference work
- or guaranteed of any accuracy.
- Last updated for 2.4.19pre7-ac1
- Tested Hardware block config lan proc scsi
- -----------------------------------------------------------------------
- Current Release
- AMI MegaRAID[0] YES YES N/A YES N/A
- Previous Stable Release (2.4.18ac3)
- AMI MegaRAID[0] FAIL
- DPT Smartraid ------------ Use dpt_i2o module ------------
- Intel SCU RAID FAIL[2] ??? N/A ??? FAIL[2]
- Promise Supertrak100 YES[3] YES[3] N/A YES[3] N/A
- Promise SX6000 YES[3] YES[3] N/A YES[3] N/A
- Symbios FC920 YES YES[4] N/A YES YES
- [0] In I2O mode. For normal mode use the megaraid driver
- [1] Initialisation oddities and scsi failure. Use dpt_i2o module instead.
- [2] Card hangs under certain load patterns.
- [3] The driver works correctly. Certain values are misreported by this
- card but the results are only cosmetic. Firmware updates are required for some
- very early cards. Set the card into I2O not 'Linux' mode.
- [4] HTML configuration mode not available.
- Requirements
- ------------
- I2O 1.5 compliant hardware
- PCI bus interrupt driven I2O devices
- Devices in classes Block, Lan or SCSI.
- 32bit I2O messages supported
- Limitations
- -----------
- 64bit message formats are not supported (64bit I2O is basically a whole
- different driver variant)
- I2O Tape class is not supported (no known devices using this..)
- Currently only 32bit x86 platforms are supported.

- Credits
- --------
- This work was made possible by
- Red Hat
- Funding for the Building #3 part of the project
- Symbios Logic (Now LSI)
- Host adapters, hints, known to work platforms when I hit
- compatibility problems
- BoxHill Corporation
- Loan of initial FibreChannel disk array used for development work.
- European Comission
- Funding the work done by the University of Helsinki
- SysKonnect
- Loan of FDDI and Gigabit Ethernet cards
- ASUSTeK
- Loan of I2O motherboard
- Promise
- Providing a Supertrak 100 board and support info
- DPT (now Adaptec)
- Providing a DPT smartraid I2O card (use dpt_i2o for this
- board however)
- General:
- o Finish 64bit and big endian cleanup
- o Switch to new PCI mapping layer throughout
- o Hotswap of controllers
- o PCI IOP's without interrupts are not supported yet
- o Push FAIL handling into the core
- Block:
- o Multiple major numbers (problem goes away in 2.5)
- o Power management
- SCSI:
- Lan:
- o Performance tuning
- o Test Fibre Channel code
- Tape:
- o Anyone seen anything implementing this ?
