2021-11-05i2c: aspeed: add buffer mode transfer supportJae Hyun Yoo3-54/+72
Byte mode currently this driver uses makes lots of interrupt call which isn't good for performance and it makes the driver very timing sensitive. To improve performance of the driver, this commit adds buffer mode transfer support which uses I2C SRAM buffer instead of using a single byte buffer. AST2400: It has 2 KBytes (256 Bytes x 8 pages) of I2C SRAM buffer pool from 0x1e78a800 to 0x1e78afff that can be used for all busses with buffer pool manipulation. To simplify implementation for supporting both AST2400 and AST2500, it assigns each 128 Bytes per bus without using buffer pool manipulation so total 1792 Bytes of I2C SRAM buffer will be used. AST2500: It has 16 Bytes of individual I2C SRAM buffer per each bus and its range is from 0x1e78a200 to 0x1e78a2df, so it doesn't have 'buffer page selection' bit field in the Function control register, and neither 'base address pointer' bit field in the Pool buffer control register it has. To simplify implementation for supporting both AST2400 and AST2500, it writes zeros on those register bit fields but it's okay because it does nothing in AST2500. It provides buffer based master and slave data transfer. Signed-off-by: Jae Hyun Yoo <jae.hyun.yoo@intel.com>

2021-11-05char: ipmi: Add clock control logic into Aspeed LPC KCS driverJae Hyun Yoo2-1/+9
If LPC KCS driver is registered ahead of lpc-ctrl module, LPC KCS block will be enabled without heart beating of LCLK until lpc-ctrl enables the LCLK. This issue causes improper handling on host interrupts when the host sends interrupt in that time frame. Then kernel eventually forcibly disables the interrupt with dumping stack and printing a 'nobody cared this irq' message out. To prevent this issue, all LPC sub-nodes should enable LCLK individually so this patch adds clock control logic into the LPC KCS driver.

2021-10-29riscv: Do not re-populate shadow memory with kasan_populate_early_shadowAlexandre Ghiti1-11/+0
When calling this function, all the shadow memory is already populated with kasan_early_shadow_pte which has PAGE_KERNEL protection. kasan_populate_early_shadow write-protects the mapping of the range of addresses passed in argument in zero_pte_populate, which actually write-protects all the shadow memory mapping since kasan_early_shadow_pte is used for all the shadow memory at this point. And then when using memblock API to populate the shadow memory, the first write access to the kernel stack triggers a trap. This becomes visible with the next commit that contains a fix for asan-stack. We already manually populate all the shadow memory in kasan_early_init and we write-protect kasan_early_shadow_pte at the end of kasan_init which makes the calls to kasan_populate_early_shadow superfluous so we can remove them.

2021-10-27ftrace/nds32: Update the proto for ftrace_trace_function to match ftrace_stubSteven Rostedt (VMware)1-1/+1
The ftrace callback prototype was changed to pass a special ftrace_regs instead of pt_regs as the last parameter, but the static ftrace for nds32 missed updating ftrace_trace_function and this caused a warning when compared to ftrace_stub: ../arch/nds32/kernel/ftrace.c: In function '_mcount': ../arch/nds32/kernel/ftrace.c:24:35: error: comparison of distinct pointer types lacks a cast [-Werror] 24 | if (ftrace_trace_function != ftrace_stub) | ^~ Link: https://lore.kernel.org/all/20211027055554.19372-1-rdunlap@infradead.org/ Link: https://lkml.kernel.org/r/20211027125101.33449969@gandalf.local.home Cc: Ingo Molnar <mingo@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Nick Hu <nickhu@andestech.com> Cc: Greentime Hu <green.hu@gmail.com> Cc: Vincent Chen <deanbo422@gmail.com> Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: stable@vger.kernel.org Fixes: d19ad0775dcd6 ("ftrace: Have the callbacks receive a struct ftrace_regs instead of pt_regs") Reported-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
2021-10-27KVM: SEV-ES: fix another issue with string I/O VMGEXITsPaolo Bonzini1-3/+12
If the guest requests string I/O from the hypervisor via VMGEXIT, SW_EXITINFO2 will contain the REP count. However, sev_es_string_io was incorrectly treating it as the size of the GHCB buffer in bytes. This fixes the "outsw" test in the experimental SEV tests of kvm-unit-tests.

2021-10-27nios2: Make NIOS2_DTB_SOURCE_BOOL depend on !COMPILE_TESTGuenter Roeck1-0/+1
nios2:allmodconfig builds fail with make[1]: *** No rule to make target 'arch/nios2/boot/dts/""', needed by 'arch/nios2/boot/dts/built-in.a'. Stop. make: [Makefile:1868: arch/nios2/boot/dts] Error 2 (ignored) This is seen with compile tests since those enable NIOS2_DTB_SOURCE_BOOL, which in turn enables NIOS2_DTB_SOURCE. This causes the build error because the default value for NIOS2_DTB_SOURCE is an empty string. Disable NIOS2_DTB_SOURCE_BOOL for compile tests to avoid the error.
