Marc-André Lureau	1b21518f73	char: rename CharBackend->CharFrontend The actual backend is "Chardev", CharBackend is the frontend side of it (whatever talks to the backend), let's rename it for readability.

Helge Deller	644ce5df2e	target/hppa: Implement space register hashing for 64-bit HP-UX The Linux kernel turns space-register hashing off unconditionally at bootup. That code was provided by HP at the beginning of the PA-RISC Linux porting effort, and I don't know why it was decided then why Linux should not use space register hashing. 32-bit HP-UX versions seem to not use space register hashing either. But for 64-bit HP-UX versions, Sven Schnelle noticed that space register hashing needs to be enabled and is required, otherwise the HP-UX kernel will crash badly. On 64-bit CPUs space register hashing is controlled by a bit in diagnose register %dr2. Since we want to support Linux and 32- and 64-bit HP-UX, we need to fully emulate the diagnose registers and handle specifically the bit in %dr2. This patch adds the code to calculate the gva memory mask based on the space-register hashing bit in %dr2 and the PSW_W (64-bit) flag. The value is cached in the gva_offset_mask variable in CPUArchState and recalculated at every modification of the CPU PSW or %dr2.

Philippe Mathieu-Daudé	32cad1ffb8	include: Rename sysemu/ -> system/ Headers in include/sysemu/ are not only related to system emulation, they are also used by virtualization. Rename as system/ which is clearer. Files renamed manually then mechanical change using sed tool.

Helge Deller	dbca083513	target/hppa: Add "diag 0x101" for console output support For debugging purposes at the early stage of the bootup process, the SeaBIOS-hppa firmware sometimes needs to output characters to the serial console. Note that the serial console is the default output method for parisc machines. At this stage PCI busses and other devices haven't been initialized yet. So, SeaBIOS-hppa will not be able to find the correct I/O ports for the serial ports yet. Instead, add an emulation for the "diag 0x101" opcode to assist here. Without any other dependencies, SeaBIOS-hppa can then load the character to be printed in register %r26 and issue the diag assembly instruction. The qemu diag_console_output() helper function will then print that character to the first serial port.
