2020-03-16remoteproc: clean up notification configAlex Elder
Rearrange the config files for remoteproc and IPA to fix their interdependencies. First, have CONFIG_QCOM_Q6V5_MSS select QCOM_Q6V5_IPA_NOTIFY so the notification code is built regardless of whether IPA needs it. Next, represent QCOM_IPA as being dependent on QCOM_Q6V5_MSS rather than setting its value to match QCOM_Q6V5_COMMON (which is selected by QCOM_Q6V5_MSS). Drop all dependencies from QCOM_Q6V5_IPA_NOTIFY. The notification code will be built whenever QCOM_Q6V5_MSS is set, and it has no other dependencies.

2020-03-08remoteproc: add IPA notification to q6v5 driverAlex Elder
Set up a subdev in the q6v5 modem remoteproc driver that generates event notifications for the IPA driver to use for initialization and recovery following a modem shutdown or crash. A pair of new functions provides a way for the IPA driver to register and deregister a notification callback function that will be called whenever modem events (about to boot, running, about to shut down, etc.) occur. A void pointer value (provided by the IPA driver at registration time) and an event type are supplied to the callback function. One event, MODEM_REMOVING, is signaled whenever the q6v5 driver is about to remove the notification subdevice. It requires the IPA driver de-register its callback. This sub-device is only used by the modem subsystem (MSS) driver, so the code that adds the new subdev and allows registration and deregistration of the notifier is found in "qcom_q6v6_mss.c".

2020-01-20remoteproc: use struct_size() helperGustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct fw_rsc_vdev { ... struct fw_rsc_vdev_vring vring[0]; } __packed; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*rsc) + rsc->num_of_vrings * sizeof(struct fw_rsc_vdev_vring) with: struct_size(rsc, vring, rsc->num_of_vrings) This code was detected with the help of Coccinelle.

2020-01-20remoteproc: Initialize rproc_class before useBrandon Maier
The remoteproc_core and remoteproc drivers all initialize with module_init(). However remoteproc drivers need the rproc_class during their probe. If one of the remoteproc drivers runs init and gets through probe before remoteproc_init() runs, a NULL pointer access of rproc_class's `glue_dirs` spinlock occurs. > Unable to handle kernel NULL pointer dereference at virtual address 000000dc > pgd = c0004000 > [000000dc] *pgd=00000000 > Internal error: Oops: 5 [#1] PREEMPT ARM > Modules linked in: > CPU: 0 PID: 1 Comm: swapper Tainted: G W 4.14.106-rt56 #1 > Hardware name: Generic OMAP36xx (Flattened Device Tree) > task: c6050000 task.stack: c604a000 > PC is at rt_spin_lock+0x40/0x6c > LR is at rt_spin_lock+0x28/0x6c > pc : [<c0523c90>] lr : [<c0523c78>] psr: 60000013 > sp : c604bdc0 ip : 00000000 fp : 00000000 > r10: 00000000 r9 : c61c7c10 r8 : c6269c20 > r7 : c0905888 r6 : c6269c20 r5 : 00000000 r4 : 000000d4 > r3 : 000000dc r2 : c6050000 r1 : 00000002 r0 : 000000d4 > Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none ... > [<c0523c90>] (rt_spin_lock) from [<c03b65a4>] (get_device_parent+0x54/0x17c) > [<c03b65a4>] (get_device_parent) from [<c03b6bec>] (device_add+0xe0/0x5b4) > [<c03b6bec>] (device_add) from [<c042adf4>] (rproc_add+0x18/0xd8) > [<c042adf4>] (rproc_add) from [<c01110e4>] (my_rproc_probe+0x158/0x204) > [<c01110e4>] (my_rproc_probe) from [<c03bb6b8>] (platform_drv_probe+0x34/0x70) > [<c03bb6b8>] (platform_drv_probe) from [<c03b9dd4>] (driver_probe_device+0x2c8/0x420) > [<c03b9dd4>] (driver_probe_device) from [<c03ba02c>] (__driver_attach+0x100/0x11c) > [<c03ba02c>] (__driver_attach) from [<c03b7d08>] (bus_for_each_dev+0x7c/0xc0) > [<c03b7d08>] (bus_for_each_dev) from [<c03b910c>] (bus_add_driver+0x1cc/0x264) > [<c03b910c>] (bus_add_driver) from [<c03ba714>] (driver_register+0x78/0xf8) > [<c03ba714>] (driver_register) from [<c010181c>] (do_one_initcall+0x100/0x190) > [<c010181c>] (do_one_initcall) from [<c0800de8>] (kernel_init_freeable+0x130/0x1d0) > [<c0800de8>] (kernel_init_freeable) from [<c051eee8>] (kernel_init+0x8/0x114) > [<c051eee8>] (kernel_init) from [<c01175b0>] (ret_from_fork+0x14/0x24) > Code: e2843008 e3c2203f f5d3f000 e5922010 (e193cf9f) > ---[ end trace 0000000000000002 ]--- Signed-off-by: Brandon Maier <brandon.maier@rockwellcollins.com> Link: https://lore.kernel.org/r/20190530225223.136420-1-brandon.maier@rockwellcollins.com Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

Remoteproc started using dma_declare_coherent_memory recently, which is a bad idea from drivers, and the maintainers agreed to fix that. But until that is fixed only allow building the driver built in so that we can remove the dma_declare_coherent_memory export and prevent other drivers from "accidentally" using it like remoteproc. Note that the driver would also leak the declared coherent memory on unload if it actually was built as a module at the moment.

2019-07-24remoteproc: qcom: Move glink_ssr notification after stopBjorn Andersson
glink_ssr is used to signal a remote processor "A" about the stopping of another remote processor "B", so that in the event that remote processor B is ever booted again the fifos of the glink channel between A and B is in a known state. But if remote processor A receives this notification before B is actually stopped the newly reset fifo indices will be interpreted as there being "data" on the channel and either side of the channel will enter a fatal error handler. Move the glink_ssr notification to the "unprepare" state of the rproc_subdev to avoid this issue. This has the side effect of us not notifying the dying remote processor itself about its fate, which has been seen to block in certain resource constraint scenarios.

In some software releases the firmware images are not split up with each loadable segment in it's own file. Check the size of the loaded firmware to see if it still contains each segment to be loaded, before falling back to the split-out segments.

2019-06-29remoteproc: Use struct_size() helperGustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct resource_table { ... u32 offset[0]; } __packed; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: table->num * sizeof(table->offset[0]) + sizeof(struct resource_table) with: struct_size(table, offset, table->num) This code was detected with the help of Coccinelle.

2019-06-29remoteproc: add vendor resources handlingClement Leger
In order to allow rproc backend to handle vendor resources such as in OpenAMP, add a handle_rsc hook. This hook allow the rproc backends to handle vendor resources as they like. The hook will be called only for vendor resources and should return RSC_HANDLED on successful resource handling, RSC_IGNORED if resource was ignored, or a negative value on error.

Move the clock list to adsp_pil_data, make the pdc_reset optional and make the driver directly enable the xo, sleep and core clocks. The three clocks are previously toggled through the clock controller, but that means the same hardware block needs to be mapped in both drivers. Making the remoteproc driver enable the clocks is a nop when using the clock controller, but allow us to remove the clocks from the clock controller.
