[PATCH] docs:remove cxl3 device size

[PATCH] docs:remove cxl3 device size

[Raghu H]

cxl device typ3 size is read from the memory backend device, removing the
size option specified in cxl sample command.

Updating sample command to reflect target architecture as x86_64.

A few minor comments for v2.


A better title might be

cxl-type3 memory size is read directly from the provided memory backed end device.
Remove non existent size option.

There are two changes in here.  Please split it into two patches and
add a minimal cover letter (mostly as it gives a place for people to
respond to both of them with tags etc).

Minimize the change (and definitely don't tell people to use kvm as that's broken for
some usecases - instructions in CXL memory).

+ qemu-system-x86_64 -M q35,cxl=on -m 4G,maxmem=8G,slots=8 \
is probably the right combination (I tidied up the g / G mix whilst touching the line.

[PATCH v1 0/2] Update CXL documentation

[Raghu H]

Thanks Jonathan for quick review/comments on earlier patch, as suggested
splitting into two separate patches
https://www.mail-archive.com/qemu-devel@nongnu.org/msg952999.html

Removed the unsupported size option for cxl-type3 device, Qemu reads
the device size directly from the backend memory device config.

Currently the Qemu CXL emulation for AARCH64 is not available and its
only supported on x86_64 platform emulations. Removing the incorrect
information and populating with supported x86_64 sample command to
emulate cxl devices.

The document will be updated when the AARCH64 support is mainlined.
