2021-10-04remoteproc: meson-mx-ao-arc: fix a bit testDan Carpenter
The MESON_AO_RPROC_SRAM_USABLE_BITS macro is used like this: if (priv->sram_pa & ~MESON_AO_RPROC_SRAM_USABLE_BITS) { dev_err(dev, "SRAM address contains unusable bits\n"); The problem is that "->sram_pa" is type phys_addr_t which is potentially 64 bits. That means the MESON_AO_RPROC_SRAM_USABLE_BITS macro needs to be a 64 bit type as well to ensure that high 32 bits are cleared.

2021-09-27remoteproc: meson-mx-ao-arc: Add a driver for the AO ARC remote procesorMartin Blumenstingl
Amlogic Meson6, Meson8, Meson8b and Meson8m2 embed an ARC core in the Always-On (AO) power-domain. This is typically used for waking up the ARM cores after system suspend. The configuration is spread across three different registers: - AO_REMAP_REG0 which must be programmed to zero, it's actual purpose is unknown. There is a second remap register which is not used in the vendor kernel (which served as reference for this driver). - AO_CPU_CNTL is used to start and stop the ARC core. - AO_SECURE_REG0 in the SECBUS2 register area with unknown purpose. To boot the ARC core we also need to enable it's gate clock and trigger a reset. The actual code for this ARC core can come from an ELF binary, for example by building the Zephyr RTOS for an ARC EM4 core and then taking "zephyr.elf" as firmware. This executable does not have any "rsc table" so we are skipping rproc_elf_load_rsc_table (rproc_ops.parse_fw) and rproc_elf_find_loaded_rsc_table (rproc_ops.find_loaded_rsc_table).

2021-09-27remoteproc: qcom: q6v5: Use qmp_send to update co-processor load stateSibi Sankar
The power domains exposed by the AOSS QMP driver control the load state resources linked to modem, adsp, cdsp remoteprocs. These are used to notify the Always on Subsystem (AOSS) that a particular co-processor is up/down. AOSS uses this information to wait for the co-processors to suspend before starting its sleep sequence. These co-processors enter low-power modes independent to that of the application processor and the load state resources linked to them are expected to remain unaltered across system suspend/resume cycles. To achieve this behavior lets stop using the power-domains exposed by the AOSS QMP node and replace them with generic qmp_send interface instead.

2021-09-27dt-bindings: remoteproc: qcom: pas: Add QMP propertySibi Sankar
The load state power-domain, used by the co-processors to notify the Always on Subsystem (AOSS) that a particular co-processor is up/down, suffers from the side-effect of changing states during suspend/resume. However the co-processors enter low-power modes independent to that of the application processor and their states are expected to remain unaltered across system suspend/resume cycles. To achieve this behavior let's drop the load state power-domain and replace them with the qmp property for all SoCs supporting low power mode signalling. Due to the current broken load state implementation, we can afford the binding breakage that ensues and the remoteproc functionality will remain the same when using newer kernels with older dtbs.

2021-09-11perf tools: Allow build-id with trailing zerosNamhyung Kim
Currently perf saves a build-id with size but old versions assumes the size of 20. In case the build-id is less than 20 (like for MD5), it'd fill the rest with 0s. I saw a problem when old version of perf record saved a binary in the build-id cache and new version of perf reads the data. The symbols should be read from the build-id cache (as the path no longer has the same binary) but it failed due to mismatch in the build-id. symsrc__init: build id mismatch for /home/namhyung/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf. The build-id event in the data has 20 byte build-ids, but it saw a different size (16) when it reads the build-id of the elf file in the build-id cache. $ readelf -n ~/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf Displaying notes found in: .note.gnu.build-id Owner Data size Description GNU 0x00000010 NT_GNU_BUILD_ID (unique build ID bitstring) Build ID: 53e4c2f42a4c61a2d632d92a72afa08f Let's fix this by allowing trailing zeros if the size is different.
