2008-12-07Some cleanups after dyngen removalaurel32
this patch removes some now unused things after dyngen removal. 1. dyngen-exec.h: op_param, op _jmp and some associated macros are now unused; 2. Makefile.target: tcg-dyngen is not needed anymore 2. tcg/tcg-op.h, tcg/tcg-opc.h: gen-op.h is dead 3. tcg.c: - INDEX_op_end is now the first op - CONFIG_DYNGEN_OP is never defined 4. tcg.h: dyngen_op not needed anymore 5. exec-all.h: remove some ASM macros.

2008-12-07SCSI: Handle inquiry commands of varying length (Justin Chevrier).balrog
Openserver 5.0.5 sends an Inquiry command to the emulated SCSI disk expecting a response length of 40 bytes. Currently the response to an Inquiry command is hardcoded to 36 bytes. When receiving a response of length 36 instead of 40 Openserver panics. Modifications to original patch based on feedback from Ryan Harper and Paul Brook. Thanks guys.

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 ...

For backward operations, dstpitch and srcpitch can be negative. This leads BLTUNSAFE macro into an overflow, and as a result, it avoids performing operations that are perfectly valid.

2008-12-04Use writeback caching by default with qcow2aliguori
qcow2 writes a cluster reference count on every cluster update. This causes performance to crater when using anything but cache=writeback. This is most noticeable when using savevm. Right now, qcow2 isn't a reliable format regardless of the type of cache your using because metadata is not updated in the correct order. Considering this, I think it's somewhat reasonable to use writeback caching by default with qcow2 files. It at least avoids the massive performance regression for users until we sort out the issues in qcow2.
