From: Arjan van de Ven <arjan@xxxxxxxxxxxxxxx> The stack buffer for IPC messages was 16 bytes, limiting messages to a size of 4 (each message is 32 bit). However, the touch screen driver is trying to send messages of size 5.... (AC: Set to 20 bytes having checked the max size allowed) Signed-off-by: Arjan van de Ven <arjan@xxxxxxxxxxxxxxx> Signed-off-by: Alan Cox <alan@xxxxxxxxxxxxxxx> --- drivers/platform/x86/intel_scu_ipc.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/platform/x86/intel_scu_ipc.c b/drivers/platform/x86/intel_scu_ipc.c index 5258749..1b0d0d5 100644 --- a/drivers/platform/x86/intel_scu_ipc.c +++ b/drivers/platform/x86/intel_scu_ipc.c @@ -58,8 +58,8 @@ #define IPC_BASE_ADDR 0xFF11C000 /* IPC1 base register address */ #define IPC_MAX_ADDR 0x100 /* Maximum IPC regisers */ -#define IPC_WWBUF_SIZE 16 /* IPC Write buffer Size */ -#define IPC_RWBUF_SIZE 16 /* IPC Read buffer Size */ +#define IPC_WWBUF_SIZE 20 /* IPC Write buffer Size */ +#define IPC_RWBUF_SIZE 20 /* IPC Read buffer Size */ #define IPC_I2C_BASE 0xFF12B000 /* I2C control register base address */ #define IPC_I2C_MAX_ADDR 0x10 /* Maximum I2C regisers */ -- To unsubscribe from this list: send the line "unsubscribe platform-driver-x86" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
