Remove the autotools configure.ac and cleanup the .gitignore file. While on it update the README.rst to include the required compile steps and provide a version bump. Signed-off-by: LI Qingwu <Qing-wu.Li@leica-geosystems.com.cn> Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>

Move struct modeset_dev declaration to the file top to make it easier to find it. This aligns the code more to the kernel coding style. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
Introduce struct platsch_ctx to bundle the required state. At the moment it is just an container for the modeset_dev list but it will be extended in the upcoming commits. This commit also drops the usage of the gloabl modeset_list variable usage. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
Save the drmfd file descriptor within the platsch_ctx and make use of it. This prepares the code base for the upcoming application/library split. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
Store the dir path and base name within the platsch_ctx. The strdup() is not needed at the moment but prepares the code for the application/library split too. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>

Add platsch_create_ctx() to bundle the initialization. This prepares the code base for the upcoming application/library split. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
Add platsch_draw() to bundle the draw step. This prepares the code base for the upcoming application/library split. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
Add platsch_destroy_ctx() to bundle the final step. While on it add the missing modeset_dev free which is important once we split this part into a library. This prepares the code base for the upcoming application/library split. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
Move the default value handling out of the application main() function into platsch_init_ctx(). This prepares the code base for the upcoming application/library split. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
Use calloc which set the memory automatically to zero to remove the memset() call. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>

You're creating a shared library here, right? In that case, we should probably export symbols properly.

Yes, I addressed this with the latest version. Can you please check if my implementation is what you had in mind?

Split the single platsch.c into platsch.c and libplatsch.c. The later can be used by other projects to build custom bootsplash applications once we support building the library. During the split no changes are made except for making: struct platsch_ctx *platsch_create_ctx(const char *dir, const char *base); void platsch_destroy_ctx(struct platsch_ctx *ctx); void platsch_draw(struct platsch_ctx *ctx); public. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
This adds the support for building platsch and libplatsch. Platsch uses the static library to not cause any performance regression. By this commit the conversion from a standalone application into an application and library is complete. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
Add drmIsMaster() before dropping the master to not cause confusion due to the error message print. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
The platsch_create_ctx() allocates and init the ctx in one call but sometimes applications need to add custom data in between both steps. Therefore add platsch_alloc_ctx and platsch_init_ctx. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
This adds the support to register a custom draw operation callback which will be called during platsch_draw(). The callback has all the necessary information about the framebuffer and a reference to the framebuffer itself to update content. The information will be freed after the callback has finished, therfore the content needs to be copied by the application. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
Disable the setmode flag once it was set succefully since all further platsch_draw() calls only need an page flip operation. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
Rename the function to platsch_draw_buffer and align the function params to make it identical to the platsch_custom_draw_buffer function. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
Pass the whole contect to the helper function to align it with the code base. No functional change. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>
At the moment we rely on the 'default' visibility which was okay since all global functions are API functions. This is error prone as one could expose symbols by accident. Therefore change the behavior by setting the default visibility to 'hidden' and introducing a new macro to export selected API functions. Signed-off-by: Marco Felsch <m.felsch@pengutronix.de>

Hi,
this splits the single application into an application and library. It is based on the leica patch but is more traceable and don't expose internals to the library users instead a cookie solution is implemented.
