* remoteproc: k3-c7x: Add support for C7xv DSP on AM62A SoCJai Luthra2023-01-131-0/+12
| | | | | | | | | | | | | | Add support to the K3 DSP remoteproc driver to configure the C7xv subsystem core on AM62A SoCs. The C7xv susbsytem is based on C71 DSP with anlytics engine for deep learning purposes. The remoteproc handling for device management is similar to the C66/C71 DSPs on K3 J7 family SoCs, even though there are additional hardware accelerators and IP updates to C7xv subsystem.

| | | | | | | | | | | | | | The TI AM62A SoCs have a C7xv DSP and Analytics engine for deep learning purposes. The DSP part is similar to the C71x DSP found on K3 J7 SoCs, but additional hardware accelerators and IP are added to the subsystem for deep learning. Compatible info is updated to match AM62A SoCs.

* remoteproc: pru: Add pru_rproc_set_ctable() functionRoger Quadros2023-01-062-0/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some firmwares expect the OS drivers to configure the CTABLE entries publishing dynamically allocated memory regions. For example, the PRU Ethernet firmwares use the C28 and C30 entries for retrieving the Shared RAM and System SRAM (OCMC) areas allocated by the PRU Ethernet client driver. Provide a way for users to do that through a new API, pru_rproc_set_ctable(). The API returns 0 on success and a negative value on error. NOTE: The programmable CTABLE entries are typically re-programmed by the PRU firmwares when dealing with a certain block of memory during block processing. This API provides an interface to the PRU client drivers to publish a dynamically allocated memory block with the PRU firmware using a CTABLE entry instead of a negotiated address in shared memory. Additional synchronization may be needed between the PRU client drivers and firmwares if different addresses needs to be published at run-time reusing the same CTABLE entry. CTABLE for stands for "constant table". Each CTable entry just holds the upper address bits so PRU can reference to external memory with larger address bits. For use case please see prueth_sw_emac_config() in "drivers/net/ethernet/ti/prueth_switch.c" /* Set in constant table C28 of PRUn to ICSS Shared memory */ pru_rproc_set_ctable(prueth->pru0, PRU_C28, sharedramaddr); pru_rproc_set_ctable(prueth->pru1, PRU_C28, sharedramaddr); /* Set in constant table C30 of PRUn to OCMC memory */ pru_rproc_set_ctable(prueth->pru0, PRU_C30, ocmcaddr); pru_rproc_set_ctable(prueth->pru1, PRU_C30, ocmcaddr); Signed-off-by: Andrew F.

* remoteproc: pru: Make sysfs entries read-only for PRU client driven bootsSuman Anna2023-01-061-0/+2
| | | | | | | | | | | | | | | | | | The PRU remoteproc driver is not configured for 'auto-boot' by default, and allows to be booted either by in-kernel PRU client drivers or by userspace using the generic remoteproc sysfs interfaces. The sysfs interfaces should not be permitted to change the remoteproc firmwares or states when a PRU is being managed by an in-kernel client driver. Use the newly introduced remoteproc generic 'sysfs_read_only' flag to provide these restrictions by setting and clearing it appropriately during the PRU acquire and release steps.

* remoteproc: pru: Add APIs to get and put the PRU coresMD Danish Anwar2023-01-062-2/+156
| | | | | | | | | | | | | | | | | | | | Add two new APIs, pru_rproc_get() and pru_rproc_put(), to the PRU driver to allow client drivers to acquire and release the remoteproc device associated with a PRU core. The PRU cores are treated as resources with only one client owning it at a time. The pru_rproc_get() function returns the rproc handle corresponding to a PRU core identified by the device tree "ti,prus" property under the client node. The pru_rproc_put() is the complementary function to pru_rproc_get().

* remoteproc/mtk_scp: Move clk ops outside send_lockChen-Yu Tsai2023-01-041-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | Clocks are properly reference counted and do not need to be inside the lock range. Right now this triggers a false-positive lockdep warning on MT8192 based Chromebooks, through a combination of mtk-scp that has a cros-ec-rpmsg sub-device, the (actual) cros-ec I2C adapter registration, I2C client (not on cros-ec) probe doing i2c transfers and enabling clocks. This is a false positive because the cros-ec-rpmsg under mtk-scp does not have an I2C adapter, and also each I2C adapter and cros-ec instance have their own mutex. Move the clk operations outside of the send_lock range.

| | | | | | | | | | | | | | | | | | | Currently, the notification like QCOM_SSR_BEFORE_SHUTDOWN is not exactly sent before starting shutdown activity on remote subsystem but it is getting sent after sysmon shutdown request to remote. On getting QCOM_SSR_BEFORE_SHUTDOWN, some client want remote subsystem to be alive to communicate but as sysmon shutdown request is getting sent to remote before QCOM_SSR_BEFORE_SHUTDOWN notification sent to kernel client due to which remote is not in a condition to communicate with kernel clients. Fixing the subdevice ordering will fix this as ssr subdevice will be first one to get triggered in shutdown/stop path.

| | | | | | | | | | | | | | | | | | | | | | | Some remote processors (e.g. QCS404 CDSP, SC7180 MPSS/MSS) can be brought to life using two different bindings: 1. PIL (Peripheral Image Loader) 2. PAS (Peripheral Authentication Service) They still describe the same hardware - firmware load for remote processor - but use different methods to communicate with that processor. For these SoCs, the qcom,adsp.yaml bindings were describing the PAS method, however for easier customization of board DTS, the bindings combined additional properties from PIL: reset lines, qcom,halt-regs and additional clocks. The devices and Linux kernel drivers, when instantiated as PAS, do not use these properties, so drop them from the bindings.

| | | | | | | | | | | | | | | | | | | | | | Add the compatible for MSS as found on the MSM8953 platform. The situation is similar to the existing bindings for MSM8974: there is an additional "mss" power domain that must be voted for while starting up the remote processor. The difference is that on MSM8974 the power domain is represented as a regulator (firmware expects specific voltage) while on MSM8953 it is represented as power domain (firmware expects performance state instead of voltage). Handle this difference by adding the "mss" power domain as optional third item, and then restrict it (and make it required) only when using the MSM8953 compatible.

| | | | | | | | | | | | | | | | | Port the initialization sequence necessary for booting the modem remote processor on the MSM8909 SoC from Qualcomm's msm-3.10 release [1].

To reuse the existing code just insert some if statements where needed and add a configuration similar to the one from MSM8916.

| | | | | | | | | | | | | | | | | | | | | qcom,q6v5.txt covers multiple SoCs with quite different binding requirements. Converting this into one DT schema would require several if statements, making the DT schema overall harder to read and understand. To avoid this, follow the example of SC7180/SC7280 and split "qcom,msm8916-mss-pil" (and the equivalent deprecated "qcom,q6v5-pil" compatible) into a separate DT schema. The schema is somewhat based on the one for SC7180/SC7280 but adjusted for the old platforms. Compared to the old plain text bindings, add missing documentation for the "bam-dmux" subnode and recommend one particular approach to specify the MBA/MPSS "memory-region" (the other one is marked as deprecated).

* treewide: Convert del_timer*() to timer_shutdown*()Steven Rostedt (Google)2022-12-2569-97/+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>
