runqemu: fixes for slirp, network device and hostfwd

2017-01-23T12:05:22+00:00

Fixed: - Add QB_NETWORK_DEVICE to set network device, it will be used by both slirp and tap. - Set QB_NETWORK_DEVICE to "-device virtio-net-pci" in qemuboot.bbclass but runqemu will default to "-device e1000" when QB_NETWORK_DEVICE is not set, this is because oe-core's qemu targets support virtio-net-pci, but the one outside of oe-core may not, "-device e1000" is more common. - Set hostfwd by default: 2222 -> 22, 2323 -> 23, and it will choose a usable port when the one like 222 is being used. This can avoid conflicts when multilib slirp qemus are running. We can forward more ports by default if needed, and bsp.conf can custom it. - Use different mac sections for slirp and tap to fix conflicts when running both of them on the same host.

Use weak assignment for SERIAL_CONSOLES in qemu configuration files

2016-12-13T22:55:20+00:00

Use weak assignment for SERIAL_CONSOLES in qemu configuration files so that the value could serve as a default value and could be easily overridden in configuration files like local.conf. When using the default value for SERIAL_CONSOLES in qemux86-64,we would have annoying messages on console complaining about respawning getty on ttyS1. Although the value is set by purpose, at least we need to provide an easy way to override it.

machine/qemu*: Add comment regarding the reason for virtio-rng-pci

Bring across the comment that was in runqemu regarding why the virtio-rng-pci device was needed. This comment is added to each location where the virtio-rng-pci device is added. (From OE-Core rev: bc5d1fdea674e842e4b0c45b38782930ec133051) Signed-off-by: Nathan Rossi Signed-off-by: Richard Purdie

runqemu: Move virtio RNG to machine configuration

2016-09-23T13:56:39+00:00

Not all QEMU machines (outside of those available in OE-Core) are capable of using the virtio-rng-pci device due to various machine models not having a pci/virtio bus. This makes it such that the use of the '-device virtio-rng-pci' flag to QEMU is machine specific. This patch removes the general addition of the flag to all runqemu targets and adds the flag into the QB_OPT_APPEND for all the qemu* machines in OE-Core that support its use (which is all of them).

runqemu: Allow unique network interface MAC addresses

2016-09-09T11:07:32+00:00

Current qemu instances all share the same MAC address. This shouldn't be an issue as they are all on separate network interfaces, however on the slight chance this is causing problems, its easy enough to ensure we use unique MAC addresses based on the IP numbers we assign.

gcc, qemuppc: Explicitly disable forcing SPE flags

2016-01-31T13:29:48+00:00

G4 does not have SPE, so we make that explicit in the tune files and since we emulate G4 when building Qemu, we ensure it for qemuppc as well. GCC config for powerpc-linux is made to include SPE by default which is equivalent if the tripet was powerpc-linux*spe, this forces gcc to configure assembler to enable -mspe by default, when we do that then the kernel fails to compile with binutils 2.26, since newer assembler is smart to detect the tlbia instructions are not compatible with SPE and hence the kernel build breaks rightly. We configure the kernel for G4 as well where it enables tlbia instrucitons rightly so because it thinks its being configured for power4. So we keep the options but do not force -mspe down to assembler as default. (From OE-Core rev: 7a51776a830167e43cbd185505f62f328704e271) Signed-off-by: Khem Raj Signed-off-by: Richard Purdie

qemurunner: Use two serial ports and log console with a thread

2015-08-24T22:47:07+00:00

qemu can freeze and stop responding if the socket buffer connected to a tcp serial connection fills up. This happens of course when the reader of the serial data doesn't actually read it. This happened in the qemurunner code, because after checking for the "login:" sentinel, data was never again read from the serial connection. This patch solves the potential freeze by adding a thread to continuously read the data from the console and log it. So it also will give a full log of the console, rather than just up to the login prompt. To simplify this patch, another serial port was also added to use for the sole purpose of watching for the sentinel as well as being the interactive serial port. This will also prevent the possibility of lots of debug data on the console preventing the sentinel value from being seen due to interleaved text.
