linux.git/scripts/gdb/linux, branch v6.6.132 Clone of https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git scripts/gdb: fix interrupts.py after maple tree conversion 2025-07-17T16:35:15+00:00 Florian Fainelli florian.fainelli@broadcom.com 2025-06-25T02:10:20+00:00 f64046ae340159f31dc8fb5fcfd1ebeccc04fef3 commit a02b0cde8ee515ee0c8efd33e7fbe6830c282e69 upstream. In commit 721255b9826b ("genirq: Use a maple tree for interrupt descriptor management"), the irq_desc_tree was replaced with a sparse_irqs tree using a maple tree structure. Since the script looked for the irq_desc_tree symbol which is no longer available, no interrupts would be printed and the script output would not be useful anymore. In addition to looking up the correct symbol (sparse_irqs), a new module (mapletree.py) is added whose mtree_load() implementation is largely copied after the C version and uses the same variable and intermediate function names wherever possible to ensure that both the C and Python version be updated in the future. This restores the scripts' output to match that of /proc/interrupts.

commit a02b0cde8ee515ee0c8efd33e7fbe6830c282e69 upstream.

In commit 721255b9826b ("genirq: Use a maple tree for interrupt descriptor
management"), the irq_desc_tree was replaced with a sparse_irqs tree using
a maple tree structure.  Since the script looked for the irq_desc_tree
symbol which is no longer available, no interrupts would be printed and
the script output would not be useful anymore.

In addition to looking up the correct symbol (sparse_irqs), a new module
(mapletree.py) is added whose mtree_load() implementation is largely
copied after the C version and uses the same variable and intermediate
function names wherever possible to ensure that both the C and Python
version be updated in the future.

This restores the scripts' output to match that of /proc/interrupts.

commit 50f4d2ba26d5c3a4687ae0569be3bbf1c8f0cbed upstream.

The per-CPU MCE interrupts are looked up by reference and need to be
de-referenced before printing, otherwise we print the addresses of the
variables instead of their contents:

MCE: 18379471554386948492   Machine check exceptions

The corrected output looks like this instead now:
