QFPROM controller hardware requires 1.8V min for fuse blowing. So, this change sets the voltage to 1.8V, required to blow the fuse for qfprom-efuse controller. To disable fuse blowing, we set the voltage to 0V since this may be a shared rail and may be able to run at a lower rate when we're not blowing fuses. Fixes: 93b4e49f ("nvmem: qfprom: Add fuse blowing support") Reported-by:

This patch supports the DFL drivers be written in userspace. This is realized by exposing the userspace I/O device interfaces. The driver now only binds the ether group feature, which has no irq. So the irq support is not implemented yet. Reviewed-by:

Add support for pvpanic PCI device added in qemu [1]. At probe time, obtain the address where to read/write pvpanic events and pass it to the generic handling code. Will follow the same logic as pvpanic MMIO device driver. At remove time, unmap base address and disable PCI device.

Daniel Thompson authored
Currently kgdbts can get stuck waiting for do_sys_open() to be called in some of the current tests. This is because C compilers often automatically inline this function, which is a very thin wrapper around do_sys_openat2(), into some of its callers. gcc-10 does this on (at least) both x86 and arm64. We can fix the test suite by placing the breakpoints on do_sys_openat2() instead since that isn't (currently) inlined. However do_sys_openat2() is a static function so we cannot simply use an addressof. Since we are testing debug machinery it is acceptable to use kallsyms to lookup a suitable address because this is more or less what kdb does in the same circumstances. Re-implement lookup_addr() to be based on kallsyms rather than function pointers. Signed-off-by:

when interrupted by a signal, binder_wait_for_work currently returns -ERESTARTSYS. This error code isn't propagated to user space, but a way to handle interruption due to signals must be provided to code using this API.

Frozen tasks can't process binder transactions, so a way is required to inform transmitting ends of communication failures due to the frozen state of their receiving counterparts. Additionally, races are possible between transitions to frozen state and binder transactions enqueued to a specific process. Implement BINDER_FREEZE ioctl for user space to inform the binder driver about the intention to freeze or unfreeze a process. When the ioctl is called, block the caller until any pending binder transactions toward the target process are flushed. Return an error to transactions to processes marked as frozen. Co-developed-by:
