Commit Message

Mina Almasry May 10, 2024, 11:21 p.m. UTC
Abstrace the memory type from the page_pool so we can later add support
for new memory types. Convert the page_pool to use the new netmem type
abstraction, rather than use struct page directly.

As of this patch the netmem type is a no-op abstraction: it's always a
struct page underneath. All the page pool internals are converted to
use struct netmem instead of struct page, and the page pool now exports
2 APIs:

1. The existing struct page API.
2. The new struct netmem API.

Keeping the existing API is transitional; we do not want to refactor all
the current drivers using the page pool at once.

The netmem abstraction is currently a no-op. The page_pool uses
page_to_netmem() to convert allocated pages to netmem, and uses
netmem_to_page() to convert the netmem back to pages to pass to mm APIs,

Follow up patches to this series add non-paged netmem support to the
page_pool. This change is factored out on its own to limit the code
churn to this 1 patch, for ease of code review.

Signed-off-by: Mina Almasry <almasrymina@google.com>

---

v9:
- Fix sparse error (Simon).

v8:
- Fix napi_pp_put_page() taking netmem instead of page to fix
  patch-by-patch build error.
- Add net/netmem.h include in this patch to fix patch-by-patch build
  error.

v6:

- Rebased on top of the merged netmem_ref type.
