2023-01-19dt-bindings: arm: qcom,ids: Add a bunch of older SoCsStephan Gerhold1-0/+74
Sync the SoC IDs in qcom,ids.h with relevant entries from Qualcomm's LK bootloader [1] that is used for almost all older Qualcomm SoCs. Several of these are already supported, e.g.: - MSM8960 -> APQ8060, MSM8260, ... - MSM8976 -> APQ8076 - MSM8956 -> APQ8056 Others are currently being worked on, e.g.: - MSM8909(W) -> APQ8009(W), MSM8905, MSM8209, ... - MSM8939 -> MSM8239, ... And even all remaining ones added are close enough to what is already supported so that future support is realistic (if someone steps up to do the work). Add all of them at once to avoid having to add them one by one in the future. This will also benefit other projects making use of the same dt-bindings, e.g. bootloaders where adding support for all these SoCs is a bit easier than on Linux.

The SCM VMIDs represent predefined mappings that come from the irreplaceable and non-omittable firmware that comes with every Qualcomm SoC (unless you steal engineering samples from the factory) and help clarify otherwise totally magic numbers which we are required to pass to the secure world for some parts of the SoC to work at all (with modem being the prime example).

2022-12-28soc: qcom: dcc: Add driver support for Data Capture and Compare unit(DCC)Souradeep Chowdhury4-0/+1406
The DCC is a DMA Engine designed to capture and store data during system crash or software triggers. The DCC operates based on user inputs via the debugfs interface. The user gives addresses as inputs and these addresses are stored in the dcc sram. In case of a system crash or a manual software trigger by the user through the debugfs interface, the dcc captures and stores the values at these addresses. This patch contains the driver which has all the methods pertaining to the debugfs interface, auxiliary functions to support all the four fundamental operations of dcc namely read, write, read/modify/write and loop. The probe method here instantiates all the resources necessary for dcc to operate mainly the dedicated dcc sram where it stores the values. The DCC driver can be used for debugging purposes without going for a reboot since it can perform software triggers as well based on user inputs. Also add the documentation for debugfs entries which explains the functionalities of each debugfs file that has been created for dcc. The following is the justification of using debugfs interface over the other alternatives like sysfs/ioctls i) As can be seen from the debugfs attribute descriptions, some of the debugfs attribute files here contains multiple arguments which needs to be accepted from the user. This goes against the design style of sysfs. ii) The user input patterns have been made simple and convenient in this case with the use of debugfs interface as user doesn't need to shuffle between different files to execute one instruction as was the case on using other alternatives.

2022-12-26treewide: Convert del_timer*() to timer_shutdown*()Steven Rostedt (Google)69-97/+97
Due to several bugs caused by timers being re-armed after they are shutdown and just before they are freed, a new state of timers was added called "shutdown". After a timer is set to this state, then it can no longer be re-armed. The following script was run to find all the trivial locations where del_timer() or del_timer_sync() is called in the same function that the object holding the timer is freed. It also ignores any locations where the timer->function is modified between the del_timer*() and the free(), as that is not considered a "trivial" case. This was created by using a coccinelle script and the following commands: $ cat timer.cocci @@ expression ptr, slab; identifier timer, rfield; @@ ( - del_timer(&ptr->timer); + timer_shutdown(&ptr->timer); | - del_timer_sync(&ptr->timer); + timer_shutdown_sync(&ptr->timer); ) ... when strict when != ptr->timer ( kfree_rcu(ptr, rfield); | kmem_cache_free(slab, ptr); | kfree(ptr); ) $ spatch timer.cocci . > /tmp/t.patch $ patch -p1 < /tmp/t.patch Link: https://lore.kernel.org/lkml/20221123201306.823305113@linutronix.de/ Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org> Acked-by: Pavel Machek <pavel@ucw.cz> [ LED ] Acked-by: Kalle Valo <kvalo@kernel.org> [ wireless ] Acked-by: Paolo Abeni <pabeni@redhat.com> [ networking ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2022-12-23pstore: Properly assign mem_type propertyLuca Stefani1-1/+1
If mem-type is specified in the device tree it would end up overriding the record_size field instead of populating mem_type. As record_size is currently parsed after the improper assignment with default size 0 it continued to work as expected regardless of the value found in the device tree. Simply changing the target field of the struct is enough to get mem-type working as expected.

2022-12-23pstore: Make sure CONFIG_PSTORE_PMSG selects CONFIG_RT_MUTEXESJohn Stultz1-0/+1
In commit 76d62f24db07 ("pstore: Switch pmsg_lock to an rt_mutex to avoid priority inversion") I changed a lock to an rt_mutex. However, its possible that CONFIG_RT_MUTEXES is not enabled, which then results in a build failure, as the 0day bot detected: https://lore.kernel.org/linux-mm/202212211244.TwzWZD3H-lkp@intel.com/ Thus this patch changes CONFIG_PSTORE_PMSG to select CONFIG_RT_MUTEXES, which ensures the build will not fail.

2022-12-23cfi: Fix CFI failure with KASANSami Tolvanen1-3/+0
When CFI_CLANG and KASAN are both enabled, LLVM doesn't generate a CFI type hash for asan.module_ctor functions in translation units where CFI is disabled, which leads to a CFI failure during boot when do_ctors calls the affected constructors: CFI failure at do_basic_setup+0x64/0x90 (target: asan.module_ctor+0x0/0x28; expected type: 0xa540670c) Specifically, this happens because CFI is disabled for kernel/cfi.c. There's no reason to keep CFI disabled here anymore, so fix the failure by not filtering out CC_FLAGS_CFI for the file. Note that https://reviews.llvm.org/rG3b14862f0a96 fixed the issue where LLVM didn't emit CFI type hashes for any sanitizer constructors, but now type hashes are emitted correctly for TUs that use CFI.
