Some of the virtio devices have the same frontend name, but actually implement different devices behind the scenes through aliases. The indicator which device type to use is the architecture. On s390, we want s390 virtio devices. On everything else, we want PCI devices. Reflect this in the alias selection code. This way we fix commands like -device virtio-blk on s390x which with this patch applied select the correct virtio-blk-s390 device rather than virtio-blk-pci. Reported-by:

Commit ff71f2e8 prevent the possible crash during initialization of linux driver by checking the operating mode.This seems too strict as: - the real card could still work in mode other than normal - some buggy driver who does not set correct opmode after eeprom access So, considering rx ring address were reset to zero (which could be safely trated as an address not intened to DMA to), in order to both letting old guest work and preventing the unexpected DMA to guest, we can forbid packet receiving when rx ring address is zero.

The autoclear feature bits can be used for qcow2 file format features that are safe to "drop" by old programs that do not understand the feature. Upon opening the image file unknown autoclear feature bits are cleared and the image file header is rewritten, but this was happening too early in the code when critical header fields were not yet loaded. Process autoclear feature bits after all necessary header information has been loaded. Signed-off-by:

While looking into hot-plugging bridges, I can create a qemu segfault via: $ device_add pci-bridge Bridge chassis not specified. Each bridge is required to be assigned a unique chassis id > 0. ** ERROR:qom/object.c:389:object_delete: assertion failed: (obj->ref == 0) I'm proposing to fix this by adding a call to 'object_unparent()', before the call to qdev_free(). I see there is already a precedent for this usage pattern as seen in qdev_simple_unplug_cb(): /* can be used as ->unplug() callback for the simple cases */ int qdev_simple_unplug_cb(DeviceState *dev) { /* just zap it */ object_unparent(OBJECT(dev)); qdev_free(dev); return 0; } Signed-off-by: -

Some drivers (Linux' 8139too among them) rely on the NIC injecting an interrupt in the event of a receive buffer overflow and, accordingly, set the RxOverflow bit in the interrupt mask. Unfortunately rtl8139's can_receive method ignores the RxOverflow flag, which may lead to a situation where rtl8139 stops receiving packets (can_receive returns 0) when the receive buffer becomes full. If the driver eventually read from the receive buffer or reset the card the emulator could recover from this situation. However some implementations only do this upon receiving an interrupt with either RxOK or RxOverflow set in the ISR; interrupt that will never come because QEMU's flow control mechanisms would prevent rtl8139 from receiving any packet. Letting packets go through when the overflow interrupt is enabled makes the QEMU emulator compliant to the spec and solves the problem. This patch should fix a relatively common (in our experience) network stall observed when running enterprise distros with rtl8139 as the NIC; in some cases the 8139too device driver gets loaded and when under heavy load the network eventually stops working.

Due to a offset between the clock used to generate the in-kernel count_load_time (CLOCK_MONOTONIC) and the clock used for processing this in userspace (vm_clock), reading back the output of PIT channel 2 via port 0x61 was broken. One use cases that suffered from it was the CPU frequency calibration of SeaBIOS, which also affected IDE/AHCI timeouts. This fixes it by calibrating the offset between both clocks on kvm_pit_get and adjusting the kernel value before saving it in the userspace state. As the calibration only works while the vm_clock is running, we cache the in-kernel state across stopped phases. Signed-off-by:

tb_invalidate_phys_addr has to be called with the exact physical address of the breakpoint we add/remove, not just the page's base address. Otherwise we easily fail to flush the right TB. This breakage was introduced by the commit f3705d53 "memory: make phys_page_find() return an unadjusted". This appeared to work for some guest architectures because their cpu_get_phys_page_debug implementation returns full translated physical address, not just the base of the TARGET_PAGE_SIZE-sized page.

Currently the sector value for the geometry is masked, even if the user usesa command line parameter that explicitely gives a number. This breaks dasd devices on s390. A dasd device can have a physical block size of 4096 (== same for logical block size) and a typcial geometry of 15 heads and 12 sectors per cyl. The ibm partition detection relies on a correct geometry reported by the device. Unfortunately the current code changes 12 to 8. This would be necessary if the total size is not a multiple of logical sector size, but for dasd this is not the case. This patch checks the device size and only applies sector mask if necessary.
