| * char: ipmi: use DEVICE_ATTR helper macroDwaipayan Ray2021-08-121-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of open coding DEVICE_ATTR, use the helper macro DEVICE_ATTR_RO to replace DEVICE_ATTR with 0444 octal permissions. This was detected as a part of checkpatch evaluation investigating all reports of DEVICE_ATTR_RO warning type.

| * ipmi: rate limit ipmi smi_event failure messageWen Yang2021-08-121-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes we can't get a valid si_sm_data, and we print an error message accordingly. But the ipmi module seem to like retrying a lot, in which case we flood the kernel log with a lot of messages, eg: [46318019.164726] ipmi_si IPI0001:00: Could not set the global enables: 0xc1.

So far we are using that in arch_get_random_seed(), but it might be useful to expose the entropy through the /dev/hwrng device as well. This allows to assess the quality of the implementation, by using "rngtest" from the rng-tools package, for example. Add a simple platform driver implementing the hw_random interface. The corresponding platform device is created by the SMCCC core code, we just match it here by name and provide a module alias. Since the firmware takes care about serialisation, this can happily coexist with the arch_get_random_seed() bits.

To stay in this polling loop extend tpm_ibmvtpm_status() to return 'true' for as long as the vTPM is indicated as being busy in tpm_processing_cmd. Since the loop requires the TPM's timeouts, get them now using tpm_get_timeouts() after setting the TPM2 version flag on the chip.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dma-buf backed shared memory cannot be reliably freed and unregistered during a kexec operation even when tee_shm_free() is called on the shm from a .shutdown hook. The problem occurs because dma_buf_put() calls fput() which then uses task_work_add(), with the TWA_RESUME parameter, to queue tee_shm_release() to be called before the current task returns to user mode. However, the current task never returns to user mode before the kexec completes so the memory is never freed nor unregistered. Use tee_shm_alloc_kernel_buf() to avoid dma-buf backed shared memory allocation so that tee_shm_free() can directly call tee_shm_release(). This will ensure that the shm can be freed and unregistered during a kexec operation.

The new struct contains 'stopped' and 'tco_stopped' bools which used to be bits in a bitfield. The struct also contains the lock protecting them to potentially share the same cache line. Note that commit c545b66c6922b (tty: Serialize tcflow() with other tty flow control changes) added a padding to the original bitfield. It was for the bitfield to occupy a whole 64b word to avoid interferring stores on Alpha (cannot we evaporate this arch with weird implications to C code yet?). But it doesn't work as expected as the padding (tty_struct::unused) is aligned to a 8B boundary too and occupies some bytes from the next word. So make it reliable by: 1) setting __aligned of the struct -- that aligns the start, and 2) making 'unsigned long unused[0]' as the last member of the struct -- pads the end. This is also the perfect time to start the documentation of tty_struct where all this lives. So we start by documenting what these bools actually serve for. And why we do all the alignment dances. Only the few up-to-date information from the Theodore's comment made it into this new Kerneldoc comment. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: "David S.

Even though it presents a nearly identical API on the FPGA and host, it's almost a complete rewrite of the driver: The framework for exchanging data on a USB bus is fundamentally different from doing the same with a PCIe interface, which leaves very little in common between the existing driver and the new one for XillyUSB.

In order to share some code between the existing Xillybus driver and the one to be added, some functions are moved to xillybus_class.c XILLYBUS_CLASS is added to Kconfig and is common to all drivers in this group. The relation with the existing XILLYBUS symbol is "select" rather than "depends on" XILLYBUS_CLASS, or else "make olddefconfig" will silently turn off XILLYBUS, which is currently enabled in several distributions. XILLYBUS_CLASS doesn't depend on anything else, hence using it with "select" poses no risk for a broken configuration. After the future addition of the XillyUSB module, the tree of symbols will be as follows: XILLYBUS_CLASS --+-- XILLYBUS --+-- XILLYBUS_PCIE | | | +-- XILLYBUS_OF | +-- XILLYUSB XILLYBUS is for drivers based upon memory registers + DMA-based interfaces, and it's combined with XILLYBUS_PCIE and/or XILLYBUS_OF. XILLYUSB is for the USB variant only. Or a more detailed, bottom-up outline: * CONFIG_XILLYBUS_PCIE -> xillybus_pcie.c: Functions related to PCIe. * CONFIG_XILLYBUS_OF -> xillybus_of.c: Functions related to Xillybus as a peripheral on an FPGA / Processor combo chip. * CONFIG_XILLYBUS -> xillybus_core.c: Functions that are common to the two above, mainly access to the peripheral with memory-mapped registers and DMA. * CONFIG_XILLYUSB -> xillyusb.c: The driver for the USB variant, accesses the peripheral through the USB framework. * CONFIG_XILLYBUS_CLASS -> xillybus_class.c: The new module, which contains the class and API parts that would otherwise appear both in xillybus_core.c and xillyusb.c. Contains utility functions for the two latter. And since I'm at it, comments on the module names are added in the Kconfig's help part. The functions are exported with the non-GPL EXPORT_SYMBOL (a matter of taste).
