| Subject: habanalabs: fix mmu node address resolution in debugfs |
| |
| From: Yuri Nudelman <ynudelman@habana.ai> |
| |
| [ Upstream commit 09ae43043c748423a5dcdc7bb1e63e4dcabe9bd6 ] |
| |
| The address resolution via debugfs was not taking into consideration the |
| page offset, resulting in a wrong address. |
