From 1d92e1854c19c06c553243d29170bb4d1a9e3863 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 9 May 2023 02:57:30 +0200 Subject: [PATCH 1/2] wayland: Switch to custom timer tick The OE LVGL is configured to obtain timer tick from system timer instead of using ad-hoc mechanisms to emulate timer tick using threads or such. Use system timer to provide the tick. The tick handling implementation comes from: https://github.com/lvgl/lv_port_linux_frame_buffer.git as of commit adf2c4490e17a1b9ec1902cc412a24b3b8235c8e Upstream-Status: Inappropriate [Upstream repo is archived] Signed-off-by: Marek Vasut --- src/drivers/wayland.c | 24 ++++++++++++++++-------- 1 file changed, 16 insertions(+), 8 deletions(-) diff --git a/src/drivers/wayland.c b/src/drivers/wayland.c index 633dc18..bcebf4d 100644 --- a/src/drivers/wayland.c +++ b/src/drivers/wayland.c @@ -6,6 +6,7 @@ #if defined(USE_WAYLAND) && USE_WAYLAND #include +#include #include #include @@ -18,13 +19,22 @@ #define WAYLAND_VER_RES 320 #endif -static void * tick_thread(void * data) +uint32_t custom_tick_get(void) { - (void) data; - while(true) { - usleep(5 * 1000); - lv_tick_inc(5); - } + static uint64_t start_ms = 0; + if(start_ms == 0) { + struct timeval tv_start; + gettimeofday(&tv_start, NULL); + start_ms = (tv_start.tv_sec * 1000000 + tv_start.tv_usec) / 1000; + } + + struct timeval tv_now; + gettimeofday(&tv_now, NULL); + uint64_t now_ms; + now_ms = (tv_now.tv_sec * 1000000 + tv_now.tv_usec) / 1000; + + uint32_t time_ms = now_ms - start_ms; + return time_ms; } @@ -47,8 +57,6 @@ void hal_init(void) lv_group_t * g = lv_group_create(); lv_group_set_default(g); - static pthread_t hal_thread; - pthread_create(&hal_thread, NULL, tick_thread, NULL); } #endif -- 2.39.2
