Therefore the max/min private members in IPAIPU3 class for exposure/gain serve no use except setting initial values of exposure_ and gain_ members. Drop the max/min private members from IPAIPU3 class and set initial gain_ and exposure_ in IPAIPU3::updateSessionConfiguration(). Signed-off-by: Umang Jain Reviewed-by: Kieran Bingham --- Changes in v2: - Split into separate patch - Prepped over "v4 ipa: ipu3: Misc clean up" - Don't include max/min exposure/gain members in IPASessionConfiguration, as they aren't used anywhere. --- src/ipa/ipu3/ipu3.cpp | 26 ++------------------------ 1 file changed, 2 insertions(+), 24 deletions(-) diff --git a/src/ipa/ipu3/ipu3.cpp b/src/ipa/ipu3/ipu3.cpp index 17324616..4b6852a7 100644 --- a/src/ipa/ipu3/ipu3.cpp +++ b/src/ipa/ipu3/ipu3.cpp @@ -167,11 +167,7 @@ private: /* Camera sensor controls. */ uint32_t defVBlank_; uint32_t exposure_; - uint32_t minExposure_; - uint32_t maxExposure_; uint32_t gain_; - uint32_t minGain_; - uint32_t maxGain_; /* Interface to the Camera Helper */ std::unique_ptr camHelper_; @@ -192,10 +188,12 @@ void IPAIPU3::updateSessionConfiguration(const ControlInfoMap &sensorControls) const ControlInfo &v4l2Exposure = sensorControls.find(V4L2_CID_EXPOSURE)->second; int32_t minExposure = v4l2Exposure.min().get(); int32_t maxExposure = v4l2Exposure.max().get(); + exposure_ = minExposure; const ControlInfo &v4l2Gain = sensorControls.find(V4L2_CID_ANALOGUE_GAIN)->second; int32_t minGain = v4l2Gain.min().get(); int32_t maxGain = v4l2Gain.max().get(); + gain_ = minGain; /* * When the AGC computes the new exposure values for a frame, it needs @@ -429,32 +427,12 @@ int IPAIPU3::configure(const IPAConfigInfo &configInfo, */ ctrls_ = configInfo.sensorControls; - const auto itExp = ctrls_.find(V4L2_CID_EXPOSURE); - if (itExp == ctrls_.end()) { - LOG(IPAIPU3, Error) << "Can't find exposure control"; - return -EINVAL; - } - - const auto itGain = ctrls_.find(V4L2_CID_ANALOGUE_GAIN); - if (itGain == ctrls_.end()) { - LOG(IPAIPU3, Error) << "Can't find gain control"; - return -EINVAL; - } - const auto itVBlank = ctrls_.find(V4L2_CID_VBLANK); if (itVBlank == ctrls_.end()) { LOG(IPAIPU3, Error) << "Can't find VBLANK control"; return -EINVAL; } - minExposure_ = itExp->second.min().get(); - maxExposure_ = itExp->second.max().get(); - exposure_ = minExposure_; - - minGain_ = itGain->second.min().get(); - maxGain_ = itGain->second.max().get(); - gain_ = minGain_; - defVBlank_ = itVBlank->second.def().get(); calculateBdsGrid(configInfo.bdsOutputSize);
