This GDB script shows the vmallocinfo for user to analyze the vmalloc memory usage. Example output: 0xffff800008000000-0xffff800008009000 36864 <start_kernel+372> pages=8 vmalloc 0xffff800008009000-0xffff80000800b000 8192 <gicv2m_init_one+400> phys=0x8020000 ioremap 0xffff80000800b000-0xffff80000800d000 8192 <bpf_prog_alloc_no_stats+72> pages=1 vmalloc 0xffff80000800d000-0xffff80000800f000 8192 <bpf_jit_alloc_exec+16> pages=1 vmalloc 0xffff800008010000-0xffff80000ad30000 47316992 <paging_init+452> phys=0x40210000 vmap 0xffff80000ad30000-0xffff80000c1c0000 21561344 <paging_init+556> phys=0x42f30000 vmap 0xffff80000c1c0000-0xffff80000c370000 1769472 <paging_init+592> phys=0x443c0000 vmap 0xffff80000c370000-0xffff80000de90000 28442624 <paging_init+692> phys=0x44570000 vmap 0xffff80000de90000-0xffff80000f4c1000 23269376 <paging_init+788> phys=0x46090000 vmap 0xffff80000f4c1000-0xffff80000f4c3000 8192 <gen_pool_add_owner+112> pages=1 vmalloc 0xffff80000f4c3000-0xffff80000f4c5000 8192 <gen_pool_add_owner+112> pages=1 vmalloc 0xffff80000f4c5000-0xffff80000f4c7000 8192 <gen_pool_add_owner+112> pages=1 vmalloc Link: https://lkml.kernel.org/r/20230808083020.22254-9-Kuan-Ying.Lee@mediatek.com Signed-off-by: Kuan-Ying Lee <Kuan-Ying.Lee@mediatek.com> Cc: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Cc: Chinwen Chang <chinwen.chang@mediatek.com> Cc: Matthias Brugger <matthias.bgg@gmail.com> Cc: Qun-Wei Lin <qun-wei.lin@mediatek.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
