2022-07-15hw/nvme: fix example serial in documentationNiklas Cassel
The serial prop on the controller is actually describing the nvme subsystem serial, which has to be identical for all controllers within the same nvme subsystem. This is enforced since commit a859eb9f8f64 ("hw/nvme: enforce common serial per subsystem"). Fix the documentation, so that people copying the qemu command line example won't get an error on qemu start.

2022-06-09hw/cxl: Make the CXL fixed memory window setup a machine parameter.Jonathan Cameron
Paolo Bonzini requested this change to simplify the ongoing effort to allow machine setup entirely via RPC. Includes shortening the command line form cxl-fixed-memory-window to cxl-fmw as the command lines are extremely long even with this change. The json change is needed to ensure that there is a CXLFixedMemoryWindowOptionsList even though the actual element in the json is never used. Similar to existing SgxEpcProperties. Update qemu-options.hx to reflect that this is now a -machine parameter. The bulk of -M / -machine parameters are documented under machine, so use that in preference to M. Update cxl-test and bios-tables-test to reflect new parameters.

2022-05-13docs/cxl: Add initial Compute eXpress Link (CXL) documentation.Jonathan Cameron
Provide an introduction to the main components of a CXL system, with detailed explanation of memory interleaving, example command lines and kernel configuration. This was a challenging document to write due to the need to extract only that subset of CXL information which is relevant to either users of QEMU emulation of CXL or to those interested in the implementation. Much of CXL is concerned with specific elements of the protocol, management of memory pooling etc which is simply not relevant to what is currently planned for CXL emulation in QEMU.
