Hi Souradeep,

The mm subsystem currently provides no mechanism to map memory pages
to a specified virtual address range. A virtual address range can be
allocated using get_vm_area(), but the only function available for
mapping memory pages to a caller-specified address in that range is
io
From: Michael Kelley
With CoCo VM pages being marked not present when changing between
encrypted and decrypted, the order of updating the guest PTEs and
notifying the hypervisor doesn't matter. As such, only a single
hypervisor callback is needed, rather than one before and one after
the PTE upda
From: Michael Kelley
The functions set_memory_decrypted()/encrypted() may leave the input
memory range in an inconsistent state if an error occurs. Add comments
describing the situation and what callers must be aware of. Also add
comments in __set_memory_enc_dec() with more details on the issue
From: Michael Kelley
In preparation for temporarily marking pages not present during a
transition between encrypted and decrypted, use slow_virt_to_phys()
in the hypervisor callbacks. As long as the PFN is correct,
slow_virt_to_phys() works even if the leaf PTE is not present.
The existing functi

__set_memory_enc_pgtable() is only called from __set_memory_enc_dec()
after doing a simple validation check. Prior to commit 812b0597fb40,
__set_memory_enc_dec() did more complex checking, but now the code
can be simplified by collapsing the two functions.
No functional chan

In a CoCo VM when a page transitions from encrypted to decrypted, or vice
versa, attributes in the PTE must be updated *and* the hypervisor must
be notified of the change. Because there are two separate steps, there's
a window where the settings are inconsistent. Normally th

For SEV-SNP, the PVALIDATE instruction requires a valid virtual
address that it translates to the PFN that it operates on. Per
the spec, it translates the virtual address as if it were doing a
single byte read.
In transitioning a page between encrypted and decrypted, the di
From: Michael Kelley
The core function __change_page_attr() currently sets up a TLB flush if
a PTE is changed. But if the old value of the PTE doesn't include the
PRESENT flag, the PTE won't be in the TLB, so a flush isn't needed.
Avoid an unnecessary TLB flush by conditioning the flush on the o

Existing MANA design assigns IRQ to every CPUs, including sibling hyper-threads
in a core. This causes multiple IRQs to work on same CPU and may reduce the
network
performance with RSS.
Improve the performance by adhering the configuration for RSS, which assigns IRQ
on HT cores.
