[PATCH v8 0/6] arm64: KGDB Support

by vijay.kilari＠gmail.com

From: Vijaya Kumar K <Vijaya.Kumar(a)caviumnetworks.com> Based on the step-handler and break-handler hooks patch from Sandeepa, KGDB debugging support is added for EL1 debug in AArch64 mode. In first patch, PSTATE.D is set correctly In second patch,register layout is updated to be inline with GDB tool. Basic GDB connection, break point set/clear and info commands are supported except step/next debugging With second patch, step/next debugging support is added, where in pc is updated to point to the instruction to be stepped and stopped. With third patch, the compile time breakpoint instruction reordering is fixed by making kgbd_breakpoint() as noinline Tested with ARM64 simulator v8: - fixed comments on local_dbg_{save,restore} macros - instruction_pointer() macro to return unsigned long to fix compilation warnings v7: - Changes made to set PSTATE.D properly - Performed KGDB boot tests - Fixed compilation warnings in driver/misc/kgbdts.c Results: kgdb boot test: [32927.237895] Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled [32927.266066] kgdb: Registered I/O driver kgdbts.

[PATCH] ASoC: codecs: Make OF supported CODECs visible in Kconfig

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> Now that we have a generic card driver we can't rely on the card driver selecting the CODECs for us so make the CODECs that can be enabled with OF directly selectable in Kconfig. For the platforms not using OF it's not clear that we don't still want to have some board specific selection since the kernel needs to contain code to register the devices; ACPI could provide this from firmware does not yet support any kind of generic card. It may also be desirable to hide these if OF is not enabled to reduce noise.

[PATCH] spi/pl022: Unprepare clocks while suspended

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> When the driver was converted to clk_prepare() the suspend path didn't have any changes made so the clock remains prepared throughout the runtime of the driver. Unprepare it when suspended so that any savings that can be made as a result are made.

[PATCH v7 0/6] arm64: KGDB Support

by vijay.kilari＠gmail.com

From: Vijaya Kumar K <Vijaya.Kumar(a)caviumnetworks.com> Based on the step-handler and break-handler hooks patch from Sandeepa, KGDB debugging support is added for EL1 debug in AArch64 mode. In first patch, PSTATE.D is set correctly In second patch,register layout is updated to be inline with GDB tool. Basic GDB connection, break point set/clear and info commands are supported except step/next debugging With second patch, step/next debugging support is added, where in pc is updated to point to the instruction to be stepped and stopped. With third patch, the compile time breakpoint instruction reordering is fixed by making kgbd_breakpoint() as noinline Tested with ARM64 simulator v7: - Changes made to set PSTATE.D properly - Performed KGDB boot tests - Fixed compilation warnings in driver/misc/kgbdts.c Results: kgdb boot test: [32927.237895] Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled [32927.266066] kgdb: Registered I/O driver kgdbts.
