2012-04-21target-xtensa: fix LOOPNEZ/LOOPGTZ translationMax Filippov
Translation of LOOP instructions used to call LEND SR write handler to update LEND and invalidate relevant TBs. Now that LEND SR write handler ends TB, LOOPNEZ and LOOPGTZ generate wrong code (same as for simple LOOP). Fix it by calling wsr_lend helper directly.

2012-04-18qxl: set default values of vram*_size_mb to -1Alon Levy
The addition of those values caused a regression where not specifying any value for the vram bar size would result in a 4096 _byte_ surface area. This is ok for the windows driver but causes the X driver to be unusable. Also, it's a regression. This patch returns the default behavior of having a 64 megabyte vram BAR.

2012-04-17usb-ehci: drop assert()Gerd Hoffmann
Not sure what the purpose of the assert() was, in any case it is bogous. We can arrive there if transfer descriptors passed to us from the guest failed to pass sanity checks, i.e. it is guest-triggerable. We deal with that case by resetting the host controller. Everything is ok, no need to throw a core dump here. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-04-17usb-host: rewrite usb_linux_update_endp_tableGerd Hoffmann
This patch carries a complete rewrite of the usb descriptor parser. Changes / improvements: * We are using the USBDescriptor struct instead of hard-coded offsets now to access descriptor data. * (debug) printfs are all gone, tracepoints have been added instead. * We don't try (and fail) to skip over unneeded descriptors. We parse them all one by one. We keep track of which configuration, interface and altsetting we are looking at and use this information to figure which desciptors are in use and which we can ignore. * On parse errors we clear all endpoint information, which will disallow any communication with the device, except control endpoint messages. This makes sure we don't end up with a silly device state where half of the endpoints got enabled and the other half was left disabled. * Some sanity checks have been added. The new parser is more robust and also leaves complete device information in the trace log if you enable the ush_host_parse_* tracepoints. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-04-17usb-ehci: frindex always is a 14 bits counterHans de Goede
frindex always is a 14 bits counter, and not a 13 bits one as we were emulating. There are some subtle hints to this in the spec, first of all "Table 2-12. FRINDEX - Frame Index Register" says: "Bit 13:0 Frame Index. The value in this register increments at the end of each time frame (e.g. micro-frame). Bits [N:3] are used for the Frame List current index. This means that each location of the frame list is accessed 8 times (frames or micro-frames) before moving to the next index. The following illustrates values of N based on the value of the Frame List Size field in the USBCMD register. USBCMD[Frame List Size] Number Elements N 00b 1024 12 01b 512 11 10b 256 10 11b Reserved" Notice how the text talks about "Bits [N:3]" are used ..., it does NOT say that when N == 12 (our case) the counter will wrap from 8191 to 0, or in otherwords that it is a 13 bits counter (bits 0 - 12). The other hint is in "Table 2-10. USBSTS USB Status Register Bit Definitions": "Bit 3 Frame List Rollover - R/WC. The Host Controller sets this bit to a one when the Frame List Index (see Section 2.3.4) rolls over from its maximum value to zero. The exact value at which the rollover occurs depends on the frame list size. For example, if the frame list size (as programmed in the Frame List Size field of the USBCMD register) is 1024, the Frame Index Register rolls over every time FRINDEX[13] toggles. Similarly, if the size is 512, the Host Controller sets this bit to a one every time FRINDEX[12] toggles." Notice how this text talks about setting bit 3 when bit 13 of frindex toggles (when there are 1024 entries, so our case), so this indicates that frindex has a bit 13 making it a 14 bit counter. Besides these clear hints the real proof is in the pudding. Before this patch I could not stream data from a USB2 webcam under Windows XP, after this cam using a USB2 webcam under Windows XP works fine, and no regressions with other operating systems were seen.

2012-04-17usb-ehci: fix ehci_child_detachGerd Hoffmann
Looks like a cut+paste bug from ehci_detach. When the device itself is detached from a ehci port (ehci_detach op) we have to clear the device pointer for the companion port too. When a device gets removed from a downstream port of a usb hub (ehci_child_detach op) the ehci port where the usb hub is plugged in is not affected. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-04-17usb_packet_set_state: handle p->ep == NULLGerd Hoffmann
usb_packet_set_state can be called with p->ep = NULL. The tracepoint there tries to log endpoint information, which leads to a segfault. This patch makes usb_packet_set_state handle the NULL pointer properly. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-04-17usb-uhci: queuing fixGerd Hoffmann
When we queue up usb packets we may happen to find a already queued packet, which also might be finished at that point already. We don't want continue processing the packet at this point though, so lets just signal back we've found a in-flight packet when in queuing mode. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-04-17usb-uhci: stop queue filling when we find a in-flight tdGerd Hoffmann
Not only QHs can form rings, but TDs too. With the new queuing/pipelining support we are following TD chains and can actually walk in circles. An assert() prevents us from entering an endless loop then. Fix is easy: Just stop queuing when we figure the TD we are about to queue up is in flight already. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-04-17usb/vmstate: add parent dev pathGerd Hoffmann
... to make vmstate id string truely unique with multiple host controllers, i.e. move from "1/usb-ptr" to "0000:00:01.3/1/usb-ptr" (usb tabled connected to piix3 uhci). This obviously breaks migration. To handle this the usb bus property "full-path" is added. When setting this to false old behavior is maintained. This way current qemu will be compatible with old versions when started using '-M pc-$oldversion'. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-04-16qemu-timer.c: Remove 250us timeoutsPeter Portante
Basically, the main wait loop calls qemu_run_all_timers() unconditionally. The first thing this routine used to do is to see if a timer had been serviced, and then reset the loop timeout to the next deadline. However, the new deadlines had not been calculated at that point, as qemu_run_timers() had not been called yet for each of the clocks. So qemu_rearm_alarm_timer() would end up with a negative or zero deadline, and default to setting a 250us timeout for the loop. As qemu_run_timers() is called for each clock, the real deadlines would be put in place, but because a loop timeout was already set, the loop timeout would not be changed. Once that 250us timeout fired, the real deadline would be used for the subsequent timeout. For idle VMs, this effectively doubles the number of times through the loop, doubling the number of select() system calls, timer calls, etc. putting added scheduling pressure on the kernel. And under cgroups, this really causes a big problem because the cgroup code does not scale well. By simply running the timers before trying to rearm the timer, we always rearm with a non-zero deadline, effectively halving the number of system calls.
