Hi Umang, Thank you for the patch. s/Inlink/Inline/ in the subject line (same for 3/6). It looks like I wrote "inlinking" instead of "inlining" in my review of v3, sorry about that :-) On Thu, Mar 31, 2022 at 10:00:54PM +0530, Umang Jain via libcamera-devel wrote: > Since we have moved away from switch/case on the operation ID, > there's little reason to split the operation in two functions. > > Signed-off-by: Umang Jain <umang.jain@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> > --- > src/ipa/ipu3/ipu3.cpp | 47 +++++++++++++++++-------------------------- > 1 file changed, 18 insertions(+), 29 deletions(-) > > diff --git a/src/ipa/ipu3/ipu3.cpp b/src/ipa/ipu3/ipu3.cpp > index 7779ad58..23a9033e 100644 > --- a/src/ipa/ipu3/ipu3.cpp > +++ b/src/ipa/ipu3/ipu3.cpp > @@ -157,7 +157,6 @@ private: > ControlInfoMap *ipaControls); > void updateSessionConfiguration(const ControlInfoMap &sensorControls); > > - void fillParams(unsigned int frame, ipu3_uapi_params *params); > void parseStatistics(unsigned int frame, > int64_t frameTimestamp, > const ipu3_uapi_stats_3a *stats); > @@ -514,6 +513,9 @@ void IPAIPU3::unmapBuffers(const std::vector<unsigned int> &ids) > * \brief Fill and return a buffer with ISP processing parameters for a frame > * \param[in] frame The frame number > * \param[in] bufferId ID of the parameter buffer to fill > + * > + * Algorithms are expected to fill the IPU3 parameter buffer for the next > + * frame given their most recent processing of the ImgU statistics. > */ > void IPAIPU3::fillParamsBuffer(const uint32_t frame, const uint32_t bufferId) > { > @@ -527,7 +529,21 @@ void IPAIPU3::fillParamsBuffer(const uint32_t frame, const uint32_t bufferId) > ipu3_uapi_params *params = > reinterpret_cast<ipu3_uapi_params *>(mem.data()); > > - fillParams(frame, params); > + /* > + * The incoming params buffer may contain uninitialised data, or the > + * parameters of previously queued frames.

Since we have moved away from switch/case on the operation ID, there's little reason to split the operation in two functions.
