[LV] TURBOchannel support -- success!
by Maciej W. Rozycki 09 Jun '07

09 Jun '07

Hello, The list seems to have been rather silent recently. But in case there are still readers out there I am pleased to announce initial success with porting TURBOchannel support to the VAXstation 4000/90 equipped with the DWCTX adapter. A moderately easy addition of this support has been enabled by the recent rewrite of the TURBOchannel bus support to the driver model which is as of 2.6.21-rc1 available upstream now. Here is a bootstrap log from my system using a PMAD-A Ethernet adapter for the interface used for NFS-root. This board uses PIO transactions only, but my experiments with some other boards show DMA works correctly as well. Unfortunately the DMA API is currently unsupported, so using a card like one of the DEFTA variations is not possible out of the box. Comments are welcome, especially ones to provide incentive for more work in this area. ;-) Maciej >>> show config KA49-A V1.0-006-V4.0 08-00-2B-30-96-D8 128MB DEVNBR DEVNAM INFO ------ -------- -------------------------- 1 NVR OK 2 LCSPX OK Highres 72Hz - 8 Plane 4Mpixel FB - V1.0 3 DZ OK 4 CACHE OK 5 MEM OK 128MB 0A,0B,0C,0D=16MB, 1E,1F,1G,1H=16MB 6 FPU OK 7 IT OK 8 SYS OK 9 NI OK 10 SCSI OK 6-INITR 11 AUD OK 13 TCA OK OPT PRS V1.0 >>> boot eza0 -EZA0 * ** Welcome to Linux on VAX ** * CPU type: KA49 SID: 0x13000202 SIDEX: 0x04010002 Boot Head.S loaded at address 0x00006600 rpb/bootr5/ap/sp 0x00000000 0x00000000 0x00000EC0 0x00006400 relocated at phys address 0x0010028A Starting VM Early console enabled Linux/VAX <linux-vax(a)pergamentum.com> RPB info: .l_pfncnt=0x0003fd6d, .l_vmb_version=0x13000100, .l_badpgs=0x00000000 Physical memory: 0x0003fd6d HW pagelets, 0x00007fad pages (130742KB) CPU type: KA49, SID: 0x13000202, SIDEX: 0x04010002 VM: mapped physical from 0x80000000 to 0x87fada00, iomap from 87fae000 VM: vmalloc from 0x8ffae000 to 0x903ae000 VM: ptemap from 0x903ae000 to 0x928ae000 for 64 processes Calling start_kernel()...

[LV] [PATCH 2.6.18] dz: Remove devfs + dynamic dev fix
by Maciej W. Rozycki 27 Feb '07

27 Feb '07

This is a set of changes to update the driver now that the devfs support has been removed. Also the TTY_DRIVER_DYNAMIC_DEV flag is added so that tty_register_device() may be called directly. Signed-off-by: Maciej W. Rozycki <macro(a)linux-mips.org> --- Of course the two dz drivers should be merged eventually -- the other one has already been moved to the serial subsystem. I have a DECstation 2100 machine promised, which uses the other one, so I'll have a look at the issue once I get the system. But for now, please apply.
