ID. Issue Description Detailed Description Notes
1 GetSinkInfo EDID parsing error [Analysis] Missing array definition for parsing edid timing, causing parsing failure
[Modifications]
impl/hdmi
impl/hdmi/hal_common
interface/src/hdmi		 No impact on external interfaces
2 Division by zero error [Analysis] stFrmRate structure not initialized, sys did not call MI_VENC_PASS_OnInputPortFrcChanged
[Modifications]
impl/venc		 No impact on external interfaces
3 nvr_96_stream test, pulling all streams, result: occasional screen jitter [Analysis] disp and gop vsync do not arrive simultaneously, but wait vsync waits for disp vsync. If registers are configured immediately and trigged after waiting, the current frame configuration and previous frame configuration will be mixed, causing UI misalignment
[Modifications]
impl/fb
impl/rgn/hal_common
impl/rgn/hal_common/mhera
interface/include/rgn		 No impact on external interfaces
4 Memory leak in MI_FB_IMPL_Open when calling fb ioctl [Analysis] In some error paths, gp_stFbModDbgPams is not released causing memory leak; and when opening multiple fbs, the current code always mallocs new memory, gp_stFbModDbgPams pointer will be overwritten by new address, old ones cannot be found anymore, also causing memory leak
[Modifications]
impl/fb		 No impact on external interfaces
5 screen_0 set to 2560x1440, serial port prints RGN_ERR [Analysis] After change timing, cs gop's src stretch win is set to large resolution before change timing. When opening fb, ui gop's src stretch win will be updated but cs will not, so need to update cs gop's src stretch win in timing sync thread
[Modifications]
impl/fb		 No impact on external interfaces

7 sys module issue fix [Analysis] sys module related issue fixes
[Modifications]
impl/sys/hal_common		 No impact on external interfaces
8 roi case low probability md5 fail, and inconsistent md5 are all first frame or first frame after roi parameter change [Analysis] jpe hw didn't wait for miu done (didn't finish reading updated roi buffer), then decided whether it's roi area based on previous frame's residual roi information
[Modifications]
impl/venc		 No impact on external interfaces
9 BT1120 DISP1 HDMI+VGA DISP0, HDMI+VGA BT1120 cannot display normally [Analysis] HDMI+VGA not blocked, causing disp clock change

10 vdisp module issue fix [Analysis] vdisp module related issue fixes
[Modifications]
impl/vdisp		 No impact on external interfaces
11 Adjusting display sharpness has no effect [Analysis] PQ not enabled, PQ parameters not set correctly
[Modifications]
impl/disp/hal_common/mhera		 No impact on external interfaces
12 Serial port reports HAL_DISP_DMA_DoubleVsyncHandler [Analysis] high latency of MIU cause wdma double vsync
[Modifications]
impl/disp/hal_common/mhera		 No impact on external interfaces
13 When process exits abnormally, mmu callback shows CPU memory stomping [Analysis] When exiting abnormally, if app still has buf from mi sys get without putting back, arm64 sys doesn't flush related buf, causing memory stomping issue when buf is released but cache is flushed back
[Modifications]
interface/src/sys		 No impact on external interfaces
14 Mouse function test, when cursor moves to rightmost edge, screen lines are messy [Analysis] When mouse moves to edge, cropped gwin width is 0, actually cs gop hardware itself shouldn't set gwin w and h values less than 8
[Modifications]
impl/fb		 No impact on external interfaces
15 FB resolution switch error [Analysis] cmdq interface parameter usage error, use correct parameter instead
[Modifications]
impl/disp/hal_common/mhera		 No impact on external interfaces
