2022-03-21Use g_new() & friends where that makes obvious senseMarkus Armbruster
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T). Patch created mechanically with: $ spatch --in-place --sp-file scripts/coccinelle/use-g_new-etc.cocci \ --macro-file scripts/cocci-macro-file.h FILES...

In 2005 the author of commit daa579632d "PS2 mouse and keyboard separation (Paul Brook)" and 0e43e99c04 "PS2 mouse and keyboard separation (Paul Brook)" separated the PS/2 controller code and the PS/2 keyboard and mouse code.

2021-05-26pckbd: correctly disable PS/2 communicationVolker Rümelin
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 Rümelin
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 Rümelin
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>

Split stuff related to run state management into its own header sysemu/runstate.h. Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400 to 4200.

2017-05-23shutdown: Add source information to SHUTDOWN and RESETEric Blake
Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.

The i8042 device has outgouing IRQ line A20. Currently the IRQ is referenced by a pointer which normally is set during machine initialization. The pointer is never changed at runtime. So common GPIO model can be applied to A20 IRQ line. Note that checking for IRQ to be connected as in previous version of code is not required because qemu_set_irq will do it.

2015-01-03pckbd: set bits 2-3-6-7 of the output port by defaultPaolo Bonzini
OSes typically write 0xdd/0xdf to turn the A20 line off and on. This has bits 2-3-6-7 on, so that the output port subsection is migrated. Change the reset value and migration default to include those four bits, thus avoiding that the subsection is migrated. This strictly speaking changes guest ABI, but the long time during which we have not migrated the value means that the guests really do not care much; so the change is for all machine types.

2013-12-23qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster
In an ideal world, machines can be built by wiring devices together with configuration, not code. Unfortunately, that's not the world we live in right now. We still have quite a few devices that need to be wired up by code. If you try to device_add such a device, it'll fail in sometimes mysterious ways. If you're lucky, you get an unmysterious immediate crash. To protect users from such badness, DeviceClass member no_user used to make device models unavailable with -device / device_add, but that regressed in commit 18b6dad. The device model is still omitted from help, but is available anyway. Attempts to fix the regression have been rejected with the argument that the purpose of no_user isn't clear, and it's prone to misuse. This commit clarifies no_user's purpose. Anthony suggested to rename it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which I shorten somewhat to keep checkpatch happy. While there, make it bool. Every use of cannot_instantiate_with_device_add_yet gets a FIXME comment asking for rationale. The next few commits will clean them all up, either by providing a rationale, or by getting rid of the use. With that done, the regression fix is hopefully acceptable.
