2020-11-24firmware: xilinx: Use hash-table for api feature checkAmit Sunil Dhamne
Currently array of fix length PM_API_MAX is used to cache the pm_api version (valid or invalid). However ATF based PM APIs values are much higher then PM_API_MAX. So to include ATF based PM APIs also, use hash-table to store the pm_api version status.

2020-11-21x86/mce, cper: Pass x86 CPER through the MCA handling chainSmita Koralahalli
The kernel uses ACPI Boot Error Record Table (BERT) to report fatal errors that occurred in a previous boot. The MCA errors in the BERT are reported using the x86 Processor Error Common Platform Error Record (CPER) format. Currently, the record prints out the raw MSR values and AMD relies on the raw record to provide MCA information. Extract the raw MSR values of MCA registers from the BERT and feed them into mce_log() to decode them properly. The implementation is SMCA-specific as the raw MCA register values are given in the register offset order of the SMCA address space.

2020-11-20crypto: sha - split sha.h into sha1.h and sha2.hEric Biggers
Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

2020-11-16firmware: imx-dsp: Export functions to request/free channelsDaniel Baluta
In order to save power, we only need to request a channel when the communication with the DSP active. For this we export the following functions: - imx_dsp_request_channel, gets a channel with a given index - imx_dsp_free_channel, frees a channel with a given index Notice that we still request channels at probe to support devices that do not have PM callbacks implemented. More explanations about why requesting a channel has an effect on power savings: - requesting an mailbox channel will call mailbox's startup function. - startup function calls pm_runtime_get_sync which increments device usage count and will keep the device active. Specifically, mailbox clock will be always ON when a mailbox channel is requested.

2020-11-09firmware: gsmi: Drop the use of dma_pool_* API functionsFurquan Shaikh
GSMI driver uses dma_pool_* API functions for buffer allocation because it requires that the SMI buffers are allocated within 32-bit physical address space. However, this does not work well with IOMMU since there is no real device and hence no domain associated with the device. Since this is not a real device, it does not require any device address(IOVA) for the buffer allocations. The only requirement is to ensure that the physical address allocated to the buffer is within 32-bit physical address space. This is because the buffers have nothing to do with DMA at all. It is required for communication with firmware executing in SMI mode which has access only to the bottom 4GiB of memory. Hence, this change switches to using a SLAB cache created with SLAB_CACHE_DMA32 that guarantees that the allocation happens from the DMA32 memory zone. All calls to dma_pool_* are replaced with kmem_cache_*. In addition to that, all the code for managing the dma_pool for GSMI platform device is dropped.

Also, the IMA code will switch to this version in a future patch, and it does not incorporate the MokSbState exception in the first place.

2020-10-14firmware: arm_scmi: Fix locking in notificationsCristian Marussi
When a protocol registers its events, the notification core takes care to rescan the hashtable of pending event handlers and activate all the possibly existent handlers referring to any of the events that are just registered by the new protocol. When a pending handler becomes active the core requests and enables the corresponding events in the SCMI firmware. If, for whatever reason, the enable fails, such invalid event handler must be finally removed and freed. Let us ensure to use the scmi_put_active_handler() helper which handles properly the needed additional locking. Failing to properly acquire all the needed mutexes exposes a race that leads to the following splat being observed: WARNING: CPU: 0 PID: 388 at lib/refcount.c:28 refcount_warn_saturate+0xf8/0x148 Hardware name: ARM LTD ARM Juno Development Platform/ARM Juno Development Platform, BIOS EDK II Jun 30 2020 pstate: 40000005 (nZcv daif -PAN -UAO BTYPE=--) pc : refcount_warn_saturate+0xf8/0x148 lr : refcount_warn_saturate+0xf8/0x148 Call trace: refcount_warn_saturate+0xf8/0x148 scmi_put_handler_unlocked.isra.10+0x204/0x208 scmi_put_handler+0x50/0xa0 scmi_unregister_notifier+0x1bc/0x240 scmi_notify_tester_remove+0x4c/0x68 [dummy_scmi_consumer] scmi_dev_remove+0x54/0x68 device_release_driver_internal+0x114/0x1e8 driver_detach+0x58/0xe8 bus_remove_driver+0x88/0xe0 driver_unregister+0x38/0x68 scmi_driver_unregister+0x1c/0x28 scmi_drv_exit+0x1c/0xae0 [dummy_scmi_consumer] __arm64_sys_delete_module+0x1a4/0x268 el0_svc_common.constprop.3+0x94/0x178 do_el0_svc+0x2c/0x98 el0_sync_handler+0x148/0x1a8 el0_sync+0x158/0x180 Link: https://lore.kernel.org/r/20201013133109.49821-1-cristian.marussi@arm.com Fixes: e7c215f358a35 ("firmware: arm_scmi: Add notification callbacks-registration") Signed-off-by: Cristian Marussi <cristian.marussi@arm.com> Signed-off-by: Sudeep Holla <sudeep.holla@arm.com>

2020-10-13firmware: arm_scmi: Add missing Rx size re-initialisationSudeep Holla
Few commands provide the list of description partially and require to be called consecutively until all the descriptors are fetched completely. In such cases, we don't release the buffers and reuse them for consecutive transmits. However, currently we don't reset the Rx size which will be set as per the response for the last transmit. This may result in incorrect response size being interpretted as the firmware may repond with size greater than the one set but we read only upto the size set by previous response. Let us reset the receive buffer size to max possible in such cases as we don't know the exact size of the response.
