Subject: [PATCH] x86/xen: Calculate __max_logical_packages on PV domains
|
||||
|
||||
The kernel panics on PV domains because native_smp_cpus_done() is
|
||||
only called for HVM domains.
|
||||
|
||||
Calculate __max_logical_packages for PV domains.
|
||||
|
||||
Fixes: b4c0a7326f5d ("x86/smpboot: Fix __max_logical_packages estimate")

Synaptics devices reported it has Intertouch support,
|
||||
and it fails via PS/2 as following logs:
|
||||
|
||||
psmouse serio2: Failed to reset mouse on synaptics-pt/serio0
|
||||
psmouse serio2: Failed to enable mouse on synaptics-pt/serio0
|
||||
|
||||
Set these new devices to use SMBus to fix this issue,
|
||||
then they report SMBus version 3 is using,
|
||||
patch: https://patchwork.kernel.org/patch/9989547/ enabled SMBus ver 3 and
|
||||
makes synaptics devices work fine on SMBus mode.
