2009-09-09qdev/scsi: add scsi bus support to qdev, convert drivers.Gerd Hoffmann
* Add SCSIBus. * Add SCSIDeviceInfo, move device callbacks here. * add qdev/scsi helper functions. * convert drivers. Adding scsi disks via -device works now, i.e. you can do: -drive id=sda,if=none,... -device lsi -device scsi-disk,drive=sda legacy command lines (-drive if=scsi,...) continue to work.

2009-08-27qdev: add return value to init() callbacks.Gerd Hoffmann
Sorry folks, but it has to be. One more of these invasive qdev patches. We have a serious design bug in the qdev interface: device init callbacks can't signal failure because the init() callback has no return value. This patch fixes it. We have already one case in-tree where this is needed: Try -device virtio-blk-pci (without drive= specified) and watch qemu segfault. This patch fixes it. With usb+scsi being converted to qdev we'll get more devices where the init callback can fail for various reasons.

2008-12-10Add 64-bit Block Move support (Direct & Table Indirect) (Ryan Harper)aliguori
This patch adds support for 64-bit Block Move instructions. There are multiple modes for 64-bit Block moves, direct, indirect, and table indirect. This patch implements Direct and Table indirect moves which are needed by 64-bit windows and SYM_CONF_DMA_ADDRESSING_MODE=2 for the Linux sym53c8xx_2 driver respectively. Two helper functions are included to check which mode the guest is using. For 64-bit direct moves, we fetch a 3rd DWORD and store the value in the DBMS register. For Table Indirect moves, we look into the table for which register contains the upper 32-bits of the 64-bit address. This selector value indicates which register to pull the value from and into dnad64 register. Finally, lsi_do_dma is updated to use the approriate register to build a 64-bit DMA address if required. With this patch, Windows XP x64, 2003 SP2 x64, can now install to scsi devices. Linux SYM_CONF_DMA_ADDRESSING_MODE=2 need a quirk fixup in Patch 4 to function properly.

2008-12-07LSI53C895A: Handle empty SCRIPTS opcode (Justin Chevrier)balrog
Basically after each DMA transfer the Openserver driver would issue an empty (0) SCRIPTS opcode. As the opcode is essentially a NOP it has no second DWORD and therefore the DSP should only be incremented by 4 bytes instead of the 8 bytes we currently do. Here's a snippet of the log: lsi_scsi: Data ready tag=0x100d9 len=16384 ... lsi_scsi: SCRIPTS dsp=068c5e50 opcode 01000400 arg 07a09000 lsi_scsi: DMA addr=0x07a09000 len=1024 lsi_scsi: SCRIPTS dsp=068c5e58 opcode 00000000 arg 01000400 lsi_scsi: Wrong phase got 1 expected 0 Note the 2nd DWORD after the empty opcode; the next opcode in the DMA transfer sequence. As can be expected the address after that has the next DMA address to use. After the attached patch the DMA transfer is able to complete successfully: lsi_scsi: SCRIPTS dsp=068c5e50 opcode 01000400 arg 07a0d000 lsi_scsi: DMA addr=0x07a0d000 len=1024 lsi_scsi: SCRIPTS dsp=068c5e5c opcode 01000400 arg 07a0d400 lsi_scsi: DMA addr=0x07a0d400 len=1024 ...

2008-11-12Implement LSI53C895A quirks exposed by OpenServer (Justin Chevrier).balrog
After going through the debug log and scratching my head for quite some time. I found the following: The problem was with this block move: lsi_scsi: SCRIPTS dsp=0fae8e50 opcode 01000028 arg 00f63c40 lsi_scsi: DMA addr=0x00f63c40 len=36 The number of bytes to be transferred (len) should be 40 which corresponds to the block transfer of length 0x28 (from opcode 01000028). Instead we have a length of 36 (0x24). The code responsible for this is (in 'lsi_do_dma'): if (count > s->current_dma_len) count = s->current_dma_len; Basically we're overwriting the length 40 with the value 36 which I think we just left over in that variable from an earlier transfer. In my patch below I initialize s->current_dma_len to s->dbc before we begin the DMA transfer during Data In phase. The attached patch gets Openserver 5.0.5 past the hardware detection (and it lists the hard drive to boot, woohoo). It appears to stop a little while later (doesn't seem SCSI related), but it's been so long since I've booted Openserver I'm not sure what's supposted to happen after the HW detection using the boot/root disks. Props go to Craig Ringer for the initial post and the code that he posted some of which is in this patch. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5706 c046a42c-6fe2-441c-8c8c-71466251a162

2008-09-22LSI SCSI: raise UDC on infinite loop (Marcelo Tosatti)aliguori
Raise UDC (Unexpected Disconnect) when a large enough number of instructions has been executed by the SCRIPTS processor. This "solution" is much simpler than temporarily interrupting execution. This remedies the situation with Windows which downloads SCRIPTS code that busy loops on guest main memory. Their drivers _do_ handle UDC appropriately (at least XP and 2003). It would be nicer to actually detect infinite loops, but until then, this bandaid seems acceptable. Since the situation seems to be rare enough, raise the number of instructions to 10000 (previously 1000). Three people other than myself had success with this patch.
