[PATCH net-next v2 0/4] add frag page support in page pool
by Yunsheng Lin
This patchset adds frag page support in page pool and
enable skb's page frag recycling based on page pool in
hns3 drvier.
V2:
1. resend based on the latest net-next.
V1:
1. avoid atomic_long_read() in case of freeing or draining
page frag, and drop RFC tag.
RFC v6:
1. Disable frag page support in system 32-bit arch and
64-bit DMA.
RFC v5:
1. Rename dma_addr[0] to pp_frag_count and adjust codes
according to the rename.
RFC v4:
1. Use the dma_addr[1] to store bias.
2. Default to a pagecnt_bias of PAGE_SIZE - 1.
3. other minor comment suggested by Alexander.
RFC v3:
1. Implement the semantic of "page recycling only wait for the
page pool user instead of all user of a page"
2. Support the frag allocation of different sizes
3. Merge patch 4 & 5 to one patch as it does not make sense to
use page_pool_dev_alloc_pages() API directly with elevated
refcnt.
4. other minor comment suggested by Alexander.
RFC v2:
1. Split patch 1 to more reviewable one.
2. Repurpose the lower 12 bits of the dma address to store the
pagecnt_bias as suggested by Alexander.
3. support recycling to pool->alloc for elevated refcnt case
too.
Yunsheng Lin (4):
page_pool: keep pp info as long as page pool owns the page
page_pool: add interface to manipulate frag count in page pool
page_pool: add frag page recycling support in page pool
net: hns3: support skb's frag page recycling based on page pool

Prezentacja
by Marek Onufrowicz
Dzień dobry!
Czy mógłbym przedstawić rozwiązanie, które umożliwia monitoring każdego auta w czasie rzeczywistym w tym jego pozycję, zużycie paliwa i przebieg?
Dodatkowo nasze narzędzie minimalizuje koszty utrzymania samochodów, skraca czas przejazdów, a także tworzenie planu tras czy dostaw.
Z naszej wiedzy i doświadczenia korzysta już ponad 49 tys. Klientów. Monitorujemy 809 000 pojazdów na całym świecie, co jest naszą najlepszą wizytówką.
Bardzo proszę o e-maila zwrotnego, jeśli moglibyśmy wspólnie omówić potencjał wykorzystania takiego rozwiązania w Państwa firmie.
Pozdrawiam,
Marek Onufrowicz
