2024-07-04mei: vsc: Enhance SPI transfer of IVSC ROMWentong Wu1-1/+1
Before downloading firmware, a command response is required to identify the silicon. However, when downloading IVSC firmware, reading data from the SPI transfers with the IVSC ROM is not necessary. Therefore, the rx buffer of SPI transfer command is determined based on the specific request of the caller.

2024-07-03misc: fastrpc: Fix ownership reassignment of remote heapEkansh Gupta1-1/+3
Audio PD daemon will allocate memory for audio PD dynamic loading usage when it is attaching for the first time to audio PD. As part of this, the memory ownership is moved to the VM where audio PD can use it. In case daemon process is killed without any impact to DSP audio PD, the daemon process will retry to attach to audio PD and in this case memory won't be reallocated. If the invoke fails due to any reason, as part of err_invoke, the memory ownership is getting reassigned to HLOS even when the memory was not allocated. At this time the audio PD might still be using the memory and an attemp of ownership reassignment would result in memory issue.

When user is requesting for DSP capability, the process pd type is getting updated to USER_PD which is incorrect as DSP will assume the process which is making the request is a user PD and this will never get updated back to the original value. The actual PD type should not be updated for capability request and it should be serviced by the respective PD on DSP side. Don't change process's PD type for DSP capability request.

2024-07-03misc: fastrpc: Fix DSP capabilities requestEkansh Gupta1-3/+8
The DSP capability request call expects 2 arguments. First is the information about the total number of attributes to be copied from DSP and second is the information about the buffer where the DSP needs to copy the information. The current design is passing the information about the size to be copied from DSP which would be considered as a bad argument to the call by DSP causing a failure suggesting the same. The second argument carries the information about the buffer where the DSP needs to copy the capability information and the size to be copied. As the first entry of capability attribute is getting skipped, same should also be considered while sending the information to DSP. Add changes to pass proper arguments to DSP.

2024-06-04mei: vsc: Fix wrong invocation of ACPI SID methodHans de Goede1-1/+1
When using an initializer for a union only one of the union members must be initialized. The initializer for the acpi_object union variable passed as argument to the SID ACPI method was initializing both the type and the integer members of the union. Unfortunately rather then complaining about this gcc simply ignores the first initializer and only used the second integer.value = 1 initializer. Leaving type set to 0 which leads to the argument being skipped by acpi acpi_ns_evaluate() resulting in: ACPI Warning: \_SB.PC00.SPI1.SPFD.CVFD.SID: Insufficient arguments - Caller passed 0, method requires 1 (20240322/nsarguments-232) Fix this by initializing only the integer struct part of the union and initializing both members of the integer struct.

2024-06-04mei: vsc: Don't stop/restart mei device during system suspend/resumeWentong Wu1-24/+15
The dynamically created mei client device (mei csi) is used as one V4L2 sub device of the whole video pipeline, and the V4L2 connection graph is built by software node. The mei_stop() and mei_restart() will delete the old mei csi client device and create a new mei client device, which will cause the software node information saved in old mei csi device lost and the whole video pipeline will be broken. Removing mei_stop()/mei_restart() during system suspend/resume can fix the issue above and won't impact hardware actual power saving logic.

2024-06-04mei: demote client disconnect warning on suspend to debugAlexander Usyskin1-1/+1
Change level for the "not connected" client message in the write callback from error to debug. The MEI driver currently disconnects all clients upon system suspend. This behavior is by design and user-space applications with open connections before the suspend are expected to handle errors upon resume, by reopening their handles, reconnecting, and retrying their operations. However, the current driver implementation logs an error message every time a write operation is attempted on a disconnected client. Since this is a normal and expected flow after system resume logging this as an error can be misleading.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing cleanup from Steven Rostedt: "Remove second argument of __assign_str() The __assign_str() macro logic of the TRACE_EVENT() macro was optimized so that it no longer needs the second argument. The __assign_str() is always matched with __string() field that takes a field name and the source for that field: __string(field, source) The TRACE_EVENT() macro logic will save off the source value and then use that value to copy into the ring buffer via the __assign_str(). Before commit c1fa617caeb0 ("tracing: Rework __assign_str() and __string() to not duplicate getting the string"), the __assign_str() needed the second argument which would perform the same logic as the __string() source parameter did. Not only would this add overhead, but it was error prone as if the __assign_str() source produced something different, it may not have allocated enough for the string in the ring buffer (as the __string() source was used to determine how much to allocate) Now that the __assign_str() just uses the same string that was used in __string() it no longer needs the source parameter.

2024-05-23tracing/treewide: Remove second parameter of __assign_str()Steven Rostedt (Google)1-3/+3
With the rework of how the __string() handles dynamic strings where it saves off the source string in field in the helper structure[1], the assignment of that value to the trace event field is stored in the helper value and does not need to be passed in again. This means that with: __string(field, mystring) Which use to be assigned with __assign_str(field, mystring), no longer needs the second parameter and it is unused. With this, __assign_str() will now only get a single parameter. There's over 700 users of __assign_str() and because coccinelle does not handle the TRACE_EVENT() macro I ended up using the following sed script: git grep -l __assign_str | while read a ; do sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file; mv /tmp/test-file $a; done I then searched for __assign_str() that did not end with ';' as those were multi line assignments that the sed script above would fail to catch. Note, the same updates will need to be done for: __assign_str_len() __assign_rel_str() __assign_rel_str_len() I tested this with both an allmodconfig and an allyesconfig (build only for both).

2024-05-15misc: ntsync: mark driver as "broken" to prevent from buildingGreg Kroah-Hartman1-0/+1
The ntsync code is only partially enabled in the kernel at this point in time, creating the device node and that's about it. Don't confuse systems that expect to see a working ntsync interface by teasing it with this basic structure at this point in time, so mark the code as "broken" so that it is not built and enabled just yet. Once the rest of the code is accepted, this will be reverted so that the driver can be correctly built and used, but for now, this is the safest way forward.

2024-05-01lkdtm: Disable CFI checking for perms functionsKees Cook2-2/+2
The EXEC_RODATA test plays a lot of tricks to live in the .rodata section, and once again ran into objtool's (completely reasonable) assumptions that executable code should live in an executable section. However, this manifested only under CONFIG_CFI_CLANG=y, as one of the .cfi_sites was pointing into the .rodata section. Since we're testing non-CFI execution properties in perms.c (and rodata.c), we can disable CFI for the involved functions, and remove the CFI arguments from rodata.c entirely.
