2020-04-03loop: Better discard support for block devicesEvan Green1-11/+31
If the backing device for a loop device is itself a block device, then mirror the "write zeroes" capabilities of the underlying block device into the loop device. Copy this capability into both max_write_zeroes_sectors and max_discard_sectors of the loop device. The reason for this is that REQ_OP_DISCARD on a loop device translates into blkdev_issue_zeroout(), rather than blkdev_issue_discard(). This presents a consistent interface for loop devices (that discarded data is zeroed), regardless of the backing device type of the loop device. There should be no behavior change for loop devices backed by regular files. This change fixes blktest block/003, and removes an extraneous error print in block/013 when testing on a loop device backed by a block device that does not support discard.

2020-04-03pwm: pca9685: Fix PWM/GPIO inter-operationSven Van Asbroeck1-37/+48
This driver allows pwms to be requested as gpios via gpiolib. Obviously, it should not be allowed to request a GPIO when its corresponding PWM is already requested (and vice versa). So it requires some exclusion code. Given that the PWMm and GPIO cores are not synchronized with respect to each other, this exclusion code will also require proper synchronization. Such a mechanism was in place, but was inadvertently removed by Uwe's clean-up in commit e926b12c611c ("pwm: Clear chip_data in pwm_put()"). Upon revisiting the synchronization mechanism, we found that theoretically, it could allow two threads to successfully request conflicting PWMs/GPIOs. Replace with a bitmap which tracks PWMs in-use, plus a mutex. As long as PWM and GPIO's respective request/free functions modify the in-use bitmap while holding the mutex, proper synchronization will be guaranteed.

Add support for the Kendryte K210 RISC-V SoC. For now, this support only provides a simple sysctl driver allowing to setup the CPU and uart clock. This support is enabled through the new Kconfig option SOC_KENDRYTE and defines the config option CONFIG_K210_SYSCTL to enable the K210 SoC sysctl driver compilation. The sysctl driver also registers an early SoC initialization function allowing enabling the general purpose use of the 2MB of SRAM normally reserved for the SoC AI engine. This initialization function is automatically called before the dt early initialization using the flat dt root node compatible property matching the value "kendryte,k210".

2020-04-03riscv: Add SOC early init supportDamien Le Moal5-0/+59
Add a mechanism for early SoC initialization for platforms that need additional hardware initialization not possible through the regular device tree and drivers mechanism. With this, a SoC specific initialization function can be called very early, before DTB parsing is done by parse_dtb() in Linux RISC-V kernel setup code. This can be very useful for early hardware initialization for No-MMU kernels booted directly in M-mode because it is quite likely that no other booting stage exist prior to the No-MMU kernel. Example use of a SoC early initialization is as follows: static void vendor_abc_early_init(const void *fdt) { /* * some early init code here that can use simple matches * against the flat device tree file. */ } SOC_EARLY_INIT_DECLARE("vendor,abc", abc_early_init); This early initialization function is executed only if the flat device tree for the board has a 'compatible = "vendor,abc"' entry; Signed-off-by: Damien Le Moal <[email protected]> Signed-off-by: Anup Patel <[email protected]> Signed-off-by: Palmer Dabbelt <[email protected]>

Add handlers for unaligned load and store traps that may be generated by applications. Code heavily inspired from the OpenSBI project. Handling of the unaligned access traps is suitable for applications compiled with or without compressed instructions and is independent of the kernel CONFIG_RISCV_ISA_C option value.

2020-04-03Revert "dm: always call blk_queue_split() in dm_process_bio()"Mike Snitzer1-2/+3
This reverts commit effd58c95f277744f75d6e08819ac859dbcbd351. blk_queue_split() is causing excessive IO splitting -- because blk_max_size_offset() depends on 'chunk_sectors' limit being set and if it isn't (as is the case for DM targets!) it falls back to splitting on a 'max_sectors' boundary regardless of offset. "Fix" this by reverting back to _not_ using blk_queue_split() in dm_process_bio() for normal IO (reads and writes). Long-term fix is still TBD but it should focus on training blk_max_size_offset() to call into a DM provided hook (to call DM's max_io_len()).

2020-04-03tracing: Do not allocate buffer in trace_find_next_entry() in atomicSteven Rostedt (VMware)1-1/+20
When dumping out the trace data in latency format, a check is made to peek at the next event to compare its timestamp to the current one, and if the delta is of a greater size, it will add a marker showing so. But to do this, it needs to save the current event otherwise peeking at the next event will remove the current event. To save the event, a temp buffer is used, and if the event is bigger than the temp buffer, the temp buffer is freed and a bigger buffer is allocated. This allocation is a problem when called in atomic context. The only way this gets called via atomic context is via ftrace_dump(). Thus, use a static buffer of 128 bytes (which covers most events), and if the event is bigger than that, simply return NULL. The callers of trace_find_next_entry() need to handle a NULL case, as that's what would happen if the allocation failed. Link: https://lore.kernel.org/r/20200326091256.GR11705@shao2-debian Fixes: ff895103a84ab ("tracing: Save off entry when peeking at next entry") Reported-by: kernel test robot <[email protected]> Signed-off-by: Steven Rostedt (VMware) <[email protected]>
2020-04-03KVM: SVM: Split svm_vcpu_run inline assembly to separate fileUros Bizjak3-90/+166
The compiler (GCC) does not like the situation, where there is inline assembly block that clobbers all available machine registers in the middle of the function. This situation can be found in function svm_vcpu_run in file kvm/svm.c and results in many register spills and fills to/from stack frame. This patch fixes the issue with the same approach as was done for VMX some time ago. The big inline assembly is moved to a separate assembly .S file, taking into account all ABI requirements. There are two main benefits of the above approach: * elimination of several register spills and fills to/from stack frame, and consequently smaller function .text size. The binary size of svm_vcpu_run is lowered from 2019 to 1626 bytes. * more efficient access to a register save array. Currently, register save array is accessed as: 7b00: 48 8b 98 28 02 00 00 mov 0x228(%rax),%rbx 7b07: 48 8b 88 18 02 00 00 mov 0x218(%rax),%rcx 7b0e: 48 8b 90 20 02 00 00 mov 0x220(%rax),%rdx and passing ia pointer to a register array as an argument to a function one gets: 12: 48 8b 48 08 mov 0x8(%rax),%rcx 16: 48 8b 50 10 mov 0x10(%rax),%rdx 1a: 48 8b 58 18 mov 0x18(%rax),%rbx As a result, the total size, considering that the new function size is 229 bytes, gets lowered by 164 bytes.
