Test cases such as migrate_fault and migrate_multiple, were modified to

on that, get the proper returned results
In order to configure device coherent in test_hmm, two module parameters

The objective is to test device migration mechanism in pages marked

Device Coherent type uses device memory that is coherently accesible by

When CPU is connected throug XGMI, it has coherent
access to VRAM resource. In this case that resource
is taken from a table in the device gmc aperture base.
This resource is used along with the device type, which could
be DEVICE_PRIVATE or DEVICE_COHERENT to create the device
page map region.
is_device_coherent checker was added to is_pinnable_page and renamed
to is_longterm_pinnable_page. The reason is that device coherent
pages are not supported for longterm pinning.

Add two more parameters to set spm_addr_dev0 & spm_addr_dev1
addresses. These two parameters configure the start SP
addresses for each device in test_hmm driver.
Consequently, this configures zone device type as coherent.

This case is used to migrate pages from device memory, back to system
memory. Device coherent type memory is cache coherent from device and CPU
point of view.

migrate_vma_setup() checks that a valid vma is passed so that the page
tables can be walked to find the pfns associated with a given address
range. However in some cases the pfns are already known, such as when

From: Alistair Popple
Currently any attempts to pin a device coherent page will fail. This is
because device coherent pages need to be managed by a device driver, and
pinning them would prevent a driver from migrating them off the device.
However this is no reason to fail pinning of these
With DEVICE_COHERENT, we'll soon have vm_normal_pages() return
device-managed anonymous pages that are not LRU pages. Although they
behave like normal pages for purposes of mapping in CPU page, and for
COW. They do not support LRU lists, NUMA migration or THP.
We also introduced a FOLL_LRU flag
Device memory that is cache coherent from device and CPU point of view.
This is used on platforms that have an advanced system bus (like CAPI
or CXL). Any page of a process can be migrated to such memory. However,
no one should be allowed to pin such memory so that it can always be
evicted.
This is our MEMORY_DEVICE_COHERENT patch series rebased and updated
for current 5.19.0-rc4
Changes since the last version:
- Fixed problems with migration during long-term pinning in
get_user_pages
- Open coded vm_normal_lru_pages as suggested in previous code review
- Update hmm_gup_test with

It does not apply on top of 5.18.7 nor on top of 5.19-rc4.

This test will validate we can achieve actual frequency of RP0. Pcode
grants frequencies based on what GuC is requesting. However, thermal
throttling can limit what is being granted. Add a test to request for
max, but don't fail the test if RP0 is not granted due to throttle
reasons.

Like was done for read, provide the equivalent for write. Even if
current users are not in the hot path, this should future-proof it.

- Remove default from _Generic() - callers wanting to write more
than u64 should use iosys_map_memcpy_to()
- Add WRITE_ONCE() cases dereferencing the
Instead of always falling back to memcpy_fromio() for any size, prefer
using read{b,w,l}(). When reading struct members it's common to read
individual integer variables individually. Going through memcpy_fromio()
for each of them poses a high penalty.
