Subject: [PATCH 11/23] drm/xe/svm: implement functions to allocate and free device memory
Date: Wed, 17 Jan 2024 17:12:11 -0500 [thread overview]
Message-ID: <20240117221223.18540-12-oak.zeng@intel.com> (raw)
In-Reply-To: <20240117221223.18540-1-oak.zeng@intel.com>
Function xe_devm_alloc_pages allocate pages from drm buddy and perform
house keeping work for all the pages allocated, such as get a page
refcount, keep a bitmap of all pages to denote whether a page is in
use, put pages to a drm lru list for eviction purpose.
Function xe_devm_free_blocks return all memory blocks to drm buddy
allocator.
Function xe_devm_free_page is a call back function from hmm layer. It
is called whenever a page's refcount reaches to 1. This function clears
the bit of this page in the bitmap. If all the bits in the bitmap is
cleared, it means all the pages have been freed, we return all the pages
in this memory block back to drm buddy.
