2008-09-23scsi-generic: decode correctly SCSI tape commands (Laurent Vivier)aliguori
This patch allows to use a "real" SCSI tape with qemu using "-drive /dev/sgX,if=scsi". It allows to decode correctly transfer length when the type of the device is a tape. Some issues remain when the application reading the tape tries to go beyond the end of the stream (but they must be corrected at the SCSI controller level).

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.

2008-09-1716550A UART: RHR irq enable bit also masks the Rx timeout irq.balrog
The "Rx timeout" (aka. Character Timeout Indication) has no separate mask bit in the IER register and according to the specs reading RHR is the only way to reset the irq. However on the hardware (tested on OMAP2 UART which is an extended 16550A) the RHR_IT bit in IER disables the irc, too.

2008-09-14usb: Support for removing device by host addr, improved auto filter syntax ↵aliguori
(Max Krasnyansky) This patch adds support for removing USB devices by host address. Which is usefull for things like libvirtd because there is no easy way to find guest USB address of the host device. In other words you can now do: usb_add host:3.5 ... usb_del host:3.5 Before the patch 'usb_del' did not support 'host:' notation. ---- Syntax for specifying auto connect filters has been improved. Old syntax was host:bus.dev host:pid:vid New syntax is host:auto:bus.dev[:pid:vid] In both the cases any attribute can be set to "*". New syntax is more flexible and lets you do things like host:3.*:5533:* /* grab any device on bus 3 with vendor id 5533 */ It's now possible to remove auto filters. For example: usb_del host:auto:3.*:5533:* Active filters are printed after all host devices in 'info usb' output. Which now looks like this: Device 1.1, speed 480 Mb/s Hub: USB device 1d6b:0002, EHCI Host Controller Device 1.4, speed 480 Mb/s Class 00: USB device 1058:0704, External HDD Auto filters: Device 3.* ID *:* Signed-off-by: Max Krasnyansky <maxk@kernel.org> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5205 c046a42c-6fe2-441c-8c8c-71466251a162
2008-09-11uhci: Change default transaction lifetime to 32 frames (Max Krasnyansky)aliguori
Transaction lifetime was originally set to 10 frames. That was an arbitrary number I picked without much thinking :). I'm changing that to 32 frames because things like interrupt transfers and such are scheduled at that rate. It seems like 1/32 is accepted as lowest supported rate. OHCI, for example, defines exactly 32 interrupt heads. While testing USB webcam under XP I noticed that interrupt transactions were being canceled and then resubmitted on a regular basis, which works but is a waste of CPU cycles. This change fixes that. All other devices I have are not affected.

Trivial patch adding CPU listing and the ability to do per-subtype CVR/PVR/PRR values. Presently SH7750R and SH7751R definitions are provided, as these are the ones in present use in-tree. The CVR value for SH7751R is intentionally restricted so the kernel boots, though this will want to be switched to the proper CVR value once system emulation has sufficiently stabilized. This also makes it trivial to abstract subtype specific registers like MMU_PTEA and to set up feature bits in line with the kernel probing for things like conditionalizing FPU/DSP context.

2008-08-22uhci: improved TD matching, working ISOC transfersaurel32
While trying to make VX-3000 camera work on XP under KVM I realized that we do not necessarily have to find original TD address. All we care about is the token which identifies the transfer rather well (direction, endpoint, size, etc). This is especially important for the isochronous transfers because otherwise they are being canceled left and right and we do not make much progress. With this patch all devices that used bulk transfers that I've tried so far continue to work just as well. And now my USB web cammera (isoc transfers) is working well tool. It's not as smooth as native Windows but it's pretty darn smooth. The cool thing is that new USB code (both usb-uhci and usb-linux) is totaly generic and does not need any special logic for ISOC.

The direction bit in the control register should not be directly set using PPWCONTROL. The kernel gives the following debug message. parport0 (ppdev0): use data_reverse for this! More over setting the data pins to forward mode does not work, perhaps a bug in the Linux PP driver. The right way to do this is to use PPDATADIR to set the direction. The patch checks if the user is toggling the direction bit, and invokes PPDATADIR to do the job.
