Now that map_pages_to_xen() has been extended to support 2MB mappings,
we can replace the create_mappings() calls by map_pages_to_xen() calls.
The mapping can also be marked read-only has Xen as no business to
modify the host Device Tree.

Very good! :-)
I have a small preference for making the change to PAGE_HYPERVISOR_RO in
a separate patch because it would make it easier to revert in the
future if we need so (e.g. overlays...). But it is OK either way.
The mapping is only used for early boot. For runtime we are relocating
the FDT and it is writable.
That said, I don't think the FDT should ever be writable. The size of
the FDT is bounded and therefore you will likely not be able to add a
new property/node without relocating it.
I haven't looked at latest DT overlay series. But in the previous
version I was under the impression that only the unflatten version would
be touched. IOW, the flatten version would be untouched. Can you confirm
this is still the case?

Now that xen_pt_update_entry() is able to deal with different mapping

As the function is not meant to fail, a BUG_ON() is added to check the

Am I right that we are actually destroying the mapping, which usually is
done by calling destroy_xen_mappings, but we cannot call
destroy_xen_mappings in this case because it doesn't take a flags
parameter?
You are right.
If so, then I would add a flags parameter to destroy_xen_mappings
instead of calling modify_xen_mappings just to pass _PAGE_BLOCK.
But I don't feel strongly about it so if you don't feel like making the
change to destroy_xen_mappings, you can add my acked-by here anyway.
destroy_xen_mappings() is a function used by common code. This is the
only place so far where I need to pass _PAGE_BLOCK and I don't expect it
to be used by the common code any time soon.
So I am not in favor to add an extra parameter for destroy_xen_mappings().
Would you prefer if I open-code the call to xen_pt_update?

Re: [PATCH v3 06/19] xen/arm: mm: Avoid flushing the TLBs when mapping are inserted
Hi Stefano,

From: Julien Grall
Currently, the function xen_pt_update() will flush the TLBs even when
the mappings are inserted. This is a bit wasteful because we don't
allow mapping replacement. Even if we were, the flush would need to
happen earlier because mapping replacement should use Break-Before-Make
when updating the entry.
A single call to xen_pt_update() can perform a single action. IOW, it
is not possible to, for instance, mix inserting and removing mappings.
Therefore, we can use `flags` to determine what action is performed.
This change will be particularly help to limit the impact of switching
boot time mapping to use xen_pt_update().

I am trying to think of a care where the following wouldn't be enough
but I cannot come up with one:
if ( mfn_eq(mfn, INVALID_MFN) )
flush_xen_tlb_range_va(virt, PAGE_SIZE * nr_mfns);
_PAGE_PRESENT is not set for two cases: when removing a page or
populating page-tables for a region. Both of them will expect an
INVALID_MFN (see the two asserts in xen_pt_check_entry()).
Therefore your solution should work. However, technically the 'mfn' is
ignored in both situation (hence why this is an ASSERT() rather than a
prod check).
Also, I feel it is better to flush more than less (missing a flush could
have catastrophic result). So I chose to be explicit in which case the
flush can be skipped.
Maybe it would be clearer if I write:
!((flags & _PAGE_PRESENT) && !mfn_eq(mfn, INVALID_MFN))

Here is an optional idea to make the code simpler. We could move the
flags changes (adding/removing _PAGE_CONTIG) to xen_pt_check_contig.
That way, we could remove the inner loop.
xen_pt_check_contig could check if _PAGE_CONTIG is already set and based
on alignment, it should be able to figure out when it needs to be
disabled.
My initial attempt was to do everything in a loop. But this didn't pan
out as I wanted (I felt the code was complex) and there are extra work
to be done for the next 31 entries (assuming 4KB granularity).
Hence the two loops. Unfortunately, I didn't keep my first attempt. So I
can't realy show what I wrote.

Why const? nr_mfns is an unsigned long so it is passed as value: it

Because nr_mfns is used to flush the TLBs. In the original I made the
mistake to decrement the variable and only discovered later on when the
TLB contained the wrong entry.
Such bug tends to be very subtle and it is hard to find the root cause.
So better mark the variable const to avoid any surprise.

NIT: I know we don't have vfn_to_vaddr at the moment and there is no
widespread usage of vfn in Xen anyway, but it looks off to use
pfn_to_paddr on a vfn parameter. Maybe open-code pfn_to_paddr instead?
Or introduce vfn_to_vaddr locally in this file?
To avoid inconsistency with mfn_to_maddr() and gfn_to_gaddr(), I don't
want ot introduce vfn_to_vaddr() withtout the typesafe part. I think
this is a bit over the top for now.
So I will open-code pfn_to_paddr().

Nothing very good will ensue. > Oh,,, that's a thousand true. If the free static region is the buddy of the about-to-be-free chunk, current code will merge the static region to the heap, which is unacceptable. I'll fix it in this patch serie too and I'm also preferring option 1~ And for unpopulating memory on runtime, I'll do what Jan suggests, adding a new logic of moving the page from d->page_list to d->resv_page_list in arch_free_heap_page() for reserved pages. > Technically, this is already a bug in the already merged implementation of the > static memory allocator. > > I can see two ways to fix it: >1) Update free_heap_pages() to check whether the page has PGC_reserved > set. >2) Use a different state for pages used by the static allocator. > > So far my preference is leaning towards 1.

For the whole series of patch, I tested that the series will not break
current arm64 boot of Xen with and without the CONFIG_HAS_IMX_LPUART.
Unfortunately I cannot test the functionality as I do not have the board :))
So, for this series:
