xtensa: fix kconfig unmet dependency warning for HAVE_FUTEX_CMPXCHG

2021-09-22T09:41:16Z

commit ed5aacc81cd41efc4d561e14af408d1003f7b855 upstream. XTENSA should only select HAVE_FUTEX_CMPXCHG when FUTEX is set/enabled. This prevents a kconfig warning. WARNING: unmet direct dependencies detected for HAVE_FUTEX_CMPXCHG Depends on [n]: FUTEX [=n] Selected by [y]: - XTENSA [=y] && !MMU [=n] Fixes: d951ba21b959 ("xtensa: nommu: select HAVE_FUTEX_CMPXCHG") Signed-off-by: Randy Dunlap Cc: Max Filippov Cc: Chris Zankel Cc: linux-xtensa@linux-xtensa.org Message-Id: <20210526070337.28130-1-rdunlap@infradead.org> Signed-off-by: Max Filippov Signed-off-by: Greg Kroah-Hartman

xtensa: add FORCE_MAX_ZONEORDER to Kconfig

2015-11-03T14:19:37Z

Make maximal memory allocation order configurable, so that drivers could allocate huge buffers when they need to. Signed-off-by: Max Filippov

xtensa: nommu: select HAVE_FUTEX_CMPXCHG

2015-11-02T15:03:07Z

Not having HAVE_FUTEX_CMPXCHG makes futex_detect_cmpxchg probe cmpxchg_futex_value_locked with NULL address. It's not guaranteed to fault without MMU, instead it locks up on Xtensa when there's no RAM at address 0. Select HAVE_FUTEX_CMPXCHG in noMMU Xtensa configurations. Signed-off-by: Max Filippov

xtensa: nommu: fix default memory start address

2015-11-02T15:03:05Z

RAM starts at 0x60000000 on noMMU cores, not at 0x40000000. Fix the default. Signed-off-by: Max Filippov

xtensa: implement counting and sampling perf events

2015-08-17T04:33:30Z

Xtensa Performance Monitor Module has up to 8 32 bit wide performance counters. Each counter may be enabled independently and can count any single type of hardware performance events. Event counting may be enabled and disabled globally (per PMM). Each counter has status register with bits indicating if the counter has been overflown and may be programmed to raise profiling IRQ on overflow. This IRQ is used to rewind counters and allow for counting more than 2^32 samples for counting events and to report samples for sampling events. For more details see Tensilica Debug User's Guide, chapter 8 "Performance monitor module".

xtensa: reimplement DMA API using common helpers

2015-08-17T04:31:00Z

- keep existing functionality: don't handle attributes, don't support high memory; - implement scatterlist primitives (map/unmap/sync); - enable DMA API debug. Signed-off-by: Max Filippov
