2012-11-08usb-redir: Allow packets to have both data and an error-statusHans de Goede1-36/+20

2012-11-08usb: split packet result into actual_length + statusHans de Goede24-626/+610
Since with the ehci and xhci controllers a single packet can be larger then maxpacketsize, it is possible for the result of a single packet to be both having transferred some data as well as the transfer to have an error. An example would be an input transfer from a bulk endpoint successfully receiving 1 or more maxpacketsize packets from the device, followed by a packet signalling halt. While already touching all the devices and controllers handle_packet / handle_data / handle_control code, also change the return type of these functions to void, solely storing the status in the packet. To make the code paths for regular versus async packet handling more uniform. This patch unfortunately is somewhat invasive, since makeing the qemu usb core deal with this requires changes everywhere. This patch only prepares the usb core for this, all the hcd / device changes are done in such a way that there are no functional changes. This patch has been tested with uhci and ehci hcds, together with usb-audio, usb-hid and usb-storage devices, as well as with usb-redir redirection with a wide variety of real devices. Note that there is usually no need to directly set packet->actual_length form devices handle_data callback, as that is done by usb_packet_copy() Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-11-06tcg/ppc32: Use trampolines to trim the code size for mmu slow path accessorsmalc2-9/+25
mmu access looks something like: <check tlb> if miss goto slow_path <fast path> done: ... ; end of the TB slow_path: <pre process> mr r3, r27 ; move areg0 to r3 ; (r3 holds the first argument for all the PPC32 ABIs) <call mmu_helper> b $+8 .long done <post process> b done On ppc32 <call mmu_helper> is: (SysV and Darwin) mmu_helper is most likely not within direct branching distance from the call site, necessitating a. moving 32 bit offset of mmu_helper into a GPR ; 8 bytes b. moving GPR to CTR/LR ; 4 bytes c. (finally) branching to CTR/LR ; 4 bytes r3 setting - 4 bytes call - 16 bytes dummy jump over retaddr - 4 bytes embedded retaddr - 4 bytes Total overhead - 28 bytes (PowerOpen (AIX)) a. moving 32 bit offset of mmu_helper's TOC into a GPR1 ; 8 bytes b. loading 32 bit function pointer into GPR2 ; 4 bytes c. moving GPR2 to CTR/LR ; 4 bytes d. loading 32 bit small area pointer into R2 ; 4 bytes e. (finally) branching to CTR/LR ; 4 bytes r3 setting - 4 bytes call - 24 bytes dummy jump over retaddr - 4 bytes embedded retaddr - 4 bytes Total overhead - 36 bytes Following is done to trim the code size of slow path sections: In tcg_target_qemu_prologue trampolines are emitted that look like this: trampoline: mfspr r3, LR addi r3, 4 mtspr LR, r3 ; fixup LR to point over embedded retaddr mr r3, r27 <jump mmu_helper> ; tail call of sorts And slow path becomes: slow_path: <pre process> <call trampoline> .long done <post process> b done call - 4 bytes (trampoline is within code gen buffer and most likely accessible via direct branch) embedded retaddr - 4 bytes Total overhead - 8 bytes In the end the icache pressure is decreased by 20/28 bytes at the cost of an extra jump to trampoline and adjusting LR (to skip over embedded retaddr) once inside.

Register displaychangelistener last, after spice is fully initialized, otherwise we may hit NULL pointer dereferences when qemu starts calling our callbacks. Commit e250d949feb1334828f27f0d145c35f29c4b7639 triggers this bug. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-11-05qxl: call dpy_gfx_resize when entering vga modeGerd Hoffmann1-1/+1
When entering vga mode the display size likely changes, notify all displaychangelisteners about this. Probably went unnoticed for a while as one if the first things the guest does after leaving qxl native mode and entering qxl vga mode is to set the vga video mode. But there is still a small window where qemu can operate on stale data, leading to crashes now and then. https://bugzilla.redhat.com/show_bug.cgi?id=865767 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-11-05hw/qxl: guest bug on primary create with stride %4 != 0Alon Levy1-0/+12
Due to usage of pixman for rendering on all spice surfaces we have pixman's requirement that the stride be word aligned. A guest not honoring that can crash spice and qemu with it due to failure to create a surface (in spice-server). Avoid this early on in primary surface creation and offscreen surface creation. Recently windows guests got odd width support which triggers a non word aligned primary surface in 16bit color depth. Off screen surfaces have always been word aligned, but doesn't hurt to check them here too. Signed-off-by: Alon Levy <alevy@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-11-02vl: delay thread initialization after daemonizationPaolo Bonzini2-2/+3
Commit ac4119c (chardev: Use timer instead of bottom-half to postpone open event, 2012-10-12) moved the alarm timer initialization to an earlier point but failed to consider that it depends on qemu_init_main_loop. Later, commit 1c53786 (vl: init main loop earlier, 2012-10-30) fixed this, but left -daemonize in two different ways. First, timers need to be reinitialized after forking. Second, the global mutex was being held by the parent, and thus dropped after forking. The first is now fixed using pthread_atfork. For the second part, make sure that the global mutex is not taken before daemonization, and similarly delay qemu_thread_self.

This will never happen right now (the assertion would fail). The next patch will set the socket or pipe in non-blocking mode, thus enabling this part of the code. Coroutines can just stop whenever they want with qemu_coroutine_yield. As soon as select tells the main loop that the migration stream is readable, the coroutine is re-entered directly in qemu_get_buffer, where it will read more data and pass it to the loading routines.
