Makes many several improvements to (arm64) ptdump debugging, including: - support note_page on intermediate table entries - (arm64) print intermediate entries and add an array for their specific attributes - (arm64) adjust the entry ranges to remove the implicit exclusive upper bound - (arm64) indent page table by level while maintaining attribute alignment - (arm64) improve documentation clarity, detail, and precision Thank you again to the maintainers for their review of this patch. A comparison of the differences in output is provided here: github.com/maxwell-bland/linux-patch-data/tree/main/ptdump-non-leaf New in v4: - Inclusive upper bounds on range specifications - Splits commit into multiple smaller commits and separates cosmetic, documentation, and logic changes - Updates documentation more sensibly - Fixes bug in size computation and handles ULONG_MAX bound overflow v3: https://lore.kernel.org/all/fik5ys53dbkpkl22o4s7sw7cxi6dqjcpm2f3kno5tyms73jm5y@buo4jsktsnrt/ - Added tabulation to delineate entries - Fixed formatting issues with mailer and rebased to mm/linus v2: https://lore.kernel.org/r/20240423142307.495726312-1-mbland@xxxxxxxxxxxx - Rebased onto linux-next/akpm (the incorrect branch) v1: https://lore.kernel.org/all/20240423121820.874441838-1-mbland@xxxxxxxxxxxx/ Maxwell Bland (5): mm: add ARCH_SUPPORTS_NON_LEAF_PTDUMP arm64: non leaf ptdump support arm64: indent ptdump by level, aligning attributes arm64: exclusive upper bound for ptdump entries arm64: add attrs and format to ptdump document Documentation/arch/arm64/ptdump.rst | 126 ++++++++++++----------- arch/arm64/Kconfig | 1 + arch/arm64/mm/ptdump.c | 149 +++++++++++++++++++++++++--- mm/Kconfig.debug | 9 ++ mm/ptdump.c | 21 ++-- 5 files changed, 217 insertions(+), 89 deletions(-) -- 2.39.2
