2021-05-27virtio-gpu: Add udmabuf helpersVivek Kasireddy3-0/+170
Add helper functions to create a dmabuf for a resource and mmap it. Also, introduce the fields blob and blob_size so that these helpers can start to use them but the full picture will emerge only after adding create_blob API in patch 8 of this series. To be able to create a dmabuf using the udmabuf driver, Qemu needs to be lauched with the memfd memory backend like this: qemu-system-x86_64 -m 8192m -object memory-backend-memfd,id=mem1,size=8192M -machine memory-backend=mem1 Based-on-patch-by: Gerd Hoffmann <kraxel@redhat.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Vivek Kasireddy <vivek.kasireddy@intel.com> Message-Id: <20210526231429.1045476-4-vivek.kasireddy@intel.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2021-05-26pckbd: correctly disable PS/2 communicationVolker Rümelin1-4/+47
Currently the PS/2 controller command KBD_CCMD_MOUSE_DISABLE doesn't disable the PS/2 mouse communication at all, and the PS/2 controller commands KBD_CCMD_KBD_DISABLE and KBD_CCMD_KBD_ENABLE only disable and enable the keyboard interrupt, which is very different from what a real PS/2 controller does. A guest may notice the difference. Mask out pending data on disabled queues to correctly disable the PS/2 controller communication.

2021-05-26pckbd: PS/2 keyboard throttleVolker Rümelin1-0/+61
Limit the keyboard data rate to the serial link speed. Some old DOS software relies on being able to read an incoming scan-code more than once. After reading keyboard data from the i8042 controller, the guest software has 1ms to read the same data again. Use -global i8042.kbd-throttle=on to enable this feature. To see how this patch works, start a FreeDOS 1.2 guest with the qemu option -global i8042.kbd-throttle=on and open a text file with the vim 7.3 32 bit for DOS executable. Then use the cursor keys (not the cursor keys on the numeric keypad) to move through the text. Without the kbd-throttle option enabled each keystroke will move the cursor two positions.

2021-05-26pckbd: don't update OBF flags if KBD_STAT_OBF is setVolker Rümelin2-20/+84
Don't update the OBF flags in the status register and the cor- responding IRQ lines if KBD_STAT_OBF is set. Otherwise this may change the PS/2 event type. If the guest ISR was already scheduled, the changed event type will be rather surprising for the guest. This fixes a mouse event stream corruption. To reproduce the problem start a FreeDOS 1.2 guest with -machine pc,accel=kvm and -display gtk. The KVM in-kernel irqchip has to be enabled. Now open a text file with edit.exe in the guest and hold down the cursor right key and at the same time move the mouse around. You will quickly notice erratic mouse movements and unexpected mouse clicks. A trace file shows the mouse event stream corruption. Guest rip 0xce93 (f000:ce93) is the in al,0x60 instruction in the seabios mouse ISR, guest rip 0xceca (f000:ceca) is the in al,0x60 instruction in the seabios keyboard ISR. qemu-system-x86-5659 [007] .... 280.971116: tracing_mark_write: pckbd_kbd_update_irq kbd=0 aux=1 # gtk queues a mouse event qemu-system-x86-5665 [000] .... 280.971121: kvm_exit: reason EXTERNAL_INTERRUPT rip 0x22da info 0 800000fd qemu-system-x86-5665 [000] d..1 280.971122: kvm_entry: vcpu 0, rip 0x22da qemu-system-x86-5665 [000] .... 280.971123: kvm_exit: reason EXTERNAL_INTERRUPT rip 0x22da info 0 800000fd qemu-system-x86-5665 [000] d..1 280.971124: kvm_entry: vcpu 0, rip 0x22da qemu-system-x86-5665 [000] .... 280.971126: kvm_exit: reason IO_INSTRUCTION rip 0x110c8c info 640008 0 qemu-system-x86-5665 [000] .... 280.971176: tracing_mark_write: pckbd_kbd_read_status 0x3d # KBD_STAT_OBF and KBD_STAT_MOUSE_OBF set, the mouse ISR will # read data from the PS/2 controller. qemu-system-x86-5665 [000] d..1 280.971180: kvm_entry: vcpu 0, rip 0x110c8d qemu-system-x86-5665 [000] .... 280.971191: kvm_exit: reason EXTERNAL_INTERRUPT rip 0x110c8d info 0 800000f6 qemu-system-x86-5665 [000] d..1 280.971191: kvm_entry: vcpu 0, rip 0x110c8d qemu-system-x86-5665 [000] .... 280.971193: kvm_exit: reason IO_INSTRUCTION rip 0xce93 info 600048 0 # the mouse ISR wants to read data from the PS/2 controller qemu-system-x86-5659 [007] .... 280.971231: tracing_mark_write: pckbd_kbd_update_irq kbd=1 aux=0 qemu-system-x86-5659 [007] .... 280.971238: tracing_mark_write: pckbd_kbd_update_irq kbd=1 aux=0 # gtk queues a keyboard event 0xe0 0x4d (key right) qemu-system-x86-5665 [000] .... 280.971257: tracing_mark_write: pckbd_kbd_update_irq kbd=0 aux=1 qemu-system-x86-5665 [000] .... 280.971262: tracing_mark_write: pckbd_kbd_update_irq kbd=1 aux=0 # ps2_read_data() deasserts and reasserts the keyboard IRQ qemu-system-x86-5665 [000] .... 280.971266: tracing_mark_write: pckbd_kbd_read_data 0xe0 kbd # -> the mouse ISR receives keyboard data qemu-system-x86-5665 [000] d..1 280.971268: kvm_entry: vcpu 0, rip 0xce95 qemu-system-x86-5665 [000] .... 280.971269: kvm_exit: reason IO_INSTRUCTION rip 0xe828 info a00040 0 qemu-system-x86-5665 [000] .... 280.971270: kvm_ack_irq: irqchip PIC slave pin 12 qemu-system-x86-5665 [000] d..1 280.971270: kvm_entry: vcpu 0, rip 0xe82a qemu-system-x86-5665 [000] .... 280.971271: kvm_exit: reason IO_INSTRUCTION rip 0xe82a info 200040 0 qemu-system-x86-5665 [000] .... 280.971271: kvm_ack_irq: irqchip PIC master pin 2 qemu-system-x86-5665 [000] d..1 280.971271: kvm_entry: vcpu 0, rip 0xe82c qemu-system-x86-5665 [000] .... 280.971272: kvm_exit: reason PENDING_INTERRUPT rip 0x22da info 0 0 qemu-system-x86-5665 [000] d..1 280.971273: kvm_entry: vcpu 0, rip 0x22da qemu-system-x86-5665 [000] .... 280.971274: kvm_exit: reason IO_INSTRUCTION rip 0x110c8c info 640008 0 qemu-system-x86-5665 [000] .... 280.971275: tracing_mark_write: pckbd_kbd_read_status 0x1d qemu-system-x86-5665 [000] d..1 280.971276: kvm_entry: vcpu 0, rip 0x110c8d qemu-system-x86-5665 [000] .... 280.971277: kvm_exit: reason IO_INSTRUCTION rip 0xceca info 600048 0 # the keyboard ISR wants to read data from the PS/2 controller qemu-system-x86-5665 [000] .... 280.971279: tracing_mark_write: pckbd_kbd_update_irq kbd=0 aux=1 qemu-system-x86-5665 [000] .... 280.971282: tracing_mark_write: pckbd_kbd_read_data 0x4d kbd # the keyboard ISR receives the second byte of the keyboard event Signed-off-by: Volker Rümelin <vr_qemu@t-online.de> Message-Id: <20210525181441.27768-5-vr_qemu@t-online.de> [ kraxel: add missing include ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2021-05-26ps2: don't raise an interrupt if queue is fullVolker Rümelin1-0/+4
ps2_queue() behaves differently than the very similar functions ps2_queue_2() to ps2_queue_4(). The first one calls update_irq() even if the queue is full, the others don't. Change ps2_queue() to be consistent with the others.

2021-05-26ps2: fix mouse stream corruptionVolker Rümelin1-1/+2
Commit 7abe7eb294 "ps2: Fix mouse stream corruption due to lost data" added code to avoid mouse stream corruptions but the calculation of the needed free queue size was wrong. Fix this. To reproduce, open a text file with the vim 7.3 32 bit for DOS exe- cutable in a FreeDOS client started with -display sdl and move the mouse around for a few seconds. You will quickly see erratic mouse movements and unexpected mouse clicks. CuteMouse (ctmouse.exe) in FreeDOS doesn't try to re-sync the mouse stream.

2021-05-25gitlab: add special rule for the hexagon containerAlex Bennée2-1/+32
The hexagon container is always manually built but of course not everyone will be building it themselves and pushing to their registries. We still need to create a "local" registry copy for the actual gitlab tests to run. We don't build it in this case, just pull it across from the upstream registry. We disable this rule from running on the qemu-project itself so it doesn't accidentally wipe out our master copy.
