Public bug reported:
chrome uses /proc/self/exe to fork render process.
Here a simple code to reproduce the issue. It's output parent then child but
failed with qemu: unknown option 'type=renderer'.
Maybe we can modify exec syscall to replace /proc/self/exe to the real
path.
//gcc -o self
Ok, thanks, since this was a regressin in Alpine, I'm marking the bug as
closed here.

The ARM, HPPA and RISC-V architectures don't declare any fw_cfg

Targets using the fw_cfg device might have architecture specific
keys. If so, they define the fw_cfg_arch_key_name() function.
The use of FW_CFG_MIPS is not MIPS-specific, it is simply the
architectural implementation. Rename it using the generic 'FW_CFG'
and move the Kconfig declaration in
Hi,
Quite a trivial series around fw_cfg:
- enforce the FW_CFG Kconfig symbol,
- add missing Kconfig dependencies,
- explicit machines using the fw_cfg device,
- allow targets not using the device to build without it.
Please review,
Phil.

Hi.
I'm working on a project where I want to have the linux qemu guest
communicate with another linux system via ethernet-over-usb (as far as the

This patch implements the PCIe Data Object Exchange (DOE) for PCIe 4.0/5.0
and later and CXL 2.0 "type-3" memory devices supporting the following
protocols:
1: PCIe DOE Discovery protocol
2: CXL DOE Compliance Mode protocol
3: CXL DOE CDAT protocol
Implementation is based on QEMU version
