Use DECLARE_DYNDBG_CLASSMAP across DRM: - in .c files, since macro defines/initializes a record - in drivers, $mod_{drv,drm,param}.c ie where param setup is done, since a classmap is param related - in drm/drm_print.c since existing __drm_debug param is defined there, and we ifdef it, and provide an elaborated alternative. - in drm_*_helper modules: dp/drm_dp - 1st item in makefile target drivers/gpu/drm/drm_crtc_helper.c - random pick iirc. Since these modules all use identical CLASSMAP declarations (ie: names and .class_id's) they will all respond together to "class DRM_UT_*" query-commands: :#> echo class DRM_UT_KMS +p > /proc/dynamic_debug/control NOTES: This changes __drm_debug from int to ulong, so BIT() is usable on it. DRM's enum drm_debug_category values need to sync with the index of their respective class-names here. Then .class_id == category, and dyndbg's class FOO mechanisms will enable drm_dbg(DRM_UT_KMS, ...). Though DRM needs consistent categories across all modules, thats not generally needed; modules X and Y could define FOO differently (ie a different NAME => class_id mapping), changes are made according to each module's private class-map. No callsites are actually selected by this patch, since none are class'd yet.

enum drm_debug_category has 10 categories, but is initialized with bitmasks which require 10 bits of underlying storage. By using natural enumeration, and moving the BIT(cat) into drm_debug_enabled(), the enum fits in 4 bits, allowing the category to be represented directly in pr_debug callsites, via the ddebug.class_id field. While this slightly pessimizes the bit-test in drm_debug_enabled(), using dyndbg with JUMP_LABEL will avoid the function entirely. NOTE: this change forecloses the possibility of doing: drm_dbg(DRM_UT_CORE|DRM_UT_KMS, "weird 2-cat experiment") but thats already strongly implied by the use of the enum itself; its not a normal enum if it can be 2 values simultaneously.

The entire file blames back to the start of git (minus whitespace from the RST translation and a typo fix): * there are changelog comments for March 1994 through to Linux 2.5.74 * struct tty_ldisc is two pointers nowadays, so naturally no magic * GDA_MAGIC is defined but unused, and it's been this way since start-of-git * M3_CARD_MAGIC isn't defined, because commit d56b9b9c ("[PATCH] The scheduled removal of some OSS drivers") removed the entire driver in 2006 * CS_CARD_MAGIC likewise since commit b5d425c9 ("more scheduled OSS driver removal") in 2007 * KMALLOC_MAGIC and VMALLOC_MAGIC were removed in commit e38e0cfa ("[ALSA] Remove kmalloc wrappers"), six months after start of git * SLAB_C_MAGIC has never even appeared in git (removed in 2.4.0-test3pre6) magic-number.rst is a low-value historial relic at best and misleading cruft at worst, so start with cleaning out ones that only appear therein Automated: grep MAGIC Documentation/process/magic-number.rst | while read -r mag _; do git grep -wF "$mag" | grep -vq '^Documentation.*magic-number.rst:' || sed -i "/^$mag/d" \ Documentation/{,translations/{zh_CN,zh_TW,it_IT}/}process/magic-number.rst done Signed-off-by: -

In following scenario(diagram), when one thread X running dev_coredumpm() adds devcd device to the framework which sends uevent notification to userspace and another thread Y reads this uevent and call to devcd_data_write() which eventually try to delete the queued timer that is not initialized/queued yet. So, debug object reports some warning and in the meantime, timer is initialized and queued from X path. and from Y path, it gets reinitialized again and timer->entry.pprev=NULL and try_to_grab_pending() stucks. To fix this, introduce mutex and a boolean flag to serialize the behaviour. cpu0(X) cpu1(Y) dev_coredump() uevent sent to user space device_add() ======================> user space process Y reads the uevents writes to devcd fd which results into writes to devcd_data_write() mod_delayed_work() try_to_grab_pending() del_timer() debug_assert_init() INIT_DELAYED_WORK() schedule_delayed_work() debug_object_fixup() timer_fixup_assert_init() timer_setup() do_init_timer() /* Above call reinitializes the timer to timer->entry.pprev=NULL and this will be checked later in timer_pending() call. */ timer_pending() !hlist_unhashed_lockless(&timer->entry) !h->pprev /* del_timer() checks h->pprev and finds it to be NULL due to which try_to_grab_pending() stucks. */ Link: https://lore.kernel.org/lkml/2e1f81e2-428c-f11f-ce92-eb11048cb271@quicinc.com/Signed-off-by:Mukesh Ojha <quic_mojha@quicinc.com> Link: https://lore.kernel.org/r/1663073424-13663-1-git-send-email-quic_mojha@quicinc.comSigned-off-by:

Pull driver core fixes from Greg KH: "Here are two tiny driver core fixes for 6.0-rc7 that resolve some oft-reported problems. The first is a revert of the "fw_devlink.strict=1" default option that we keep trying to enable, but we keep finding platforms that this just breaks everything on. So again, we need it reverted and hopefully it can be worked on in future releases. The second is a sysfs file-size bugfix that resolves an issue that many people are starting to hit as the fix it is fixing also was backported to stable kernels. The util-linux developers are starting to get bugreports about sysfs files that contain no data because of this problem, and this fix which has been in linux-next in the bitfield tree for a long time, resolves it. I'm submitting it here as it needs to be merged for 6.0-final, not for 6.1-rc1. Both of these have been in linux-next with no reported issues, only reports were that these fixed problems" * tag 'driver-core-6.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: drivers/base: Fix unsigned comparison to -1 in CPUMAP_FILE_MAX_BYTES Revert "driver core: Set fw_devlink.strict=1 by default"
