From: Huang Ying With this patch, a THP (Transparent Huge Page) can be added/deleted to/from the swap cache as a set of (HPAGE_PMD_NR) sub-pages. This will be used for the THP (Transparent Huge Page) swap support. Where one THP may be added/delted to/from the swap cache. This will batch the swa

[PATCH -mm -v7 0/9] THP swap: Delay splitting THP during swapping out

From: Huang Ying Hi, Andrew, could you help me to check whether the overall design is reasonable? Hi, Hugh, Shaohua, Minchan and Rik, could you help me to review the swap part of the patchset? Especially [1/9], [3/9], [4/9], [5/9], [6/9], [9/9]. Hi, Andrea could you help me to review the THP p

[PATCH -mm -v7 9/9] mm, THP, swap: Delay splitting THP during swap out

From: Huang Ying In this patch, splitting huge page is delayed from almost the first step of swapping out to after allocating the swap space for the THP (Transparent Huge Page) and adding the THP into the swap cache. This will reduce lock acquiring/releasing for the locks used for the swap cache

[PATCH -mm -v7 3/9] mm, THP, swap: Add swap cluster allocate/free functions

From: Huang Ying The swap cluster allocation/free functions are added based on the existing swap cluster management mechanism for SSD. These functions don't work for the rotating hard disks because the existing swap cluster management mechanism doesn't work for them. The hard disks support may

[PATCH -mm -v7 5/9] mm, THP, swap: Support to clear SWAP_HAS_CACHE for huge page

From: Huang Ying __swapcache_free() is added to support to clear the SWAP_HAS_CACHE flag for the huge page. This will free the specified swap cluster now. Because now this function will be called only in the error path to free the swap cluster just allocated. So the corresponding swap_map[i] ==

From: Huang Ying Separates checking whether we can split the huge page from split_huge_page_to_list() into a function. This will help to check that before splitting the THP (Transparent Huge Page) really. This will be used for delaying splitting THP during swapping out. Where for a THP, we wil

[PATCH -mm -v7 1/9] mm, swap: Make swap cluster size same of THP size on x86_64

From: Huang Ying In this patch, the size of the swap cluster is changed to that of the THP (Transparent Huge Page) on x86_64 architecture (512). This is for the THP swap support on x86_64. Where one swap cluster will be used to hold the contents of each THP swapped out. And some information of

By moving these client drivers to use RPMSG instead of the direct SMD API we can reuse them ontop of the newly added GLINK wire-protocol support found in the 820 and 835 Qualcomm platforms. As the new (RPMSG-based) and old SMD implementations are mutually exclusive we have to change all client dri
