2021-12-09Add GRALLOC_FRAMEBUFFER_NUM configurationYiMing Tseng
Add config to set the NUM_BUFFERS. Set NUM_BUFFERS to 1 can prevent page flipping and set it to a larger number can allow userspace to fill up the following frame earlier. Bug: 205917753 Change-Id: Ibf4a52a1e35f4a2404008a48b637cb82c4b46365
2019-10-15gralloc: Configure framebuffer mode according to requested image format.Peter Collingbourne
Previously we were ignoring the requested image format when mapping a graphics device via gralloc_alloc, and using the mode that the framebuffer started up in. This meant that on devices whose framebuffer starts up in a mode other than RGBA8888, we would map the framebuffer in the other mode and attempt to use it as an RGBA8888 framebuffer, which would lead to crashes or incorrecet rendering. This is the case in the ARM FVP, whose framebuffer starts up in RGB565 mode. Unfortunately there is no preferred image format passed in to fb_device_open, and we presumably cannot start passing one in for backwards compatibility reasons. Therefore, we set the image format to RGBA8888, which appears to be the only format that the platform ends up using. Bug: 142352330 Change-Id: I24000fd36910b4044ce7659605efc423e36cba00

2014-06-02gralloc: let target configure page flipping ioctlBernhard Rosenkraenzer
Let vendor choose which framebuffer ioctl (FBIOPUT_VSCREENINFO or FBIOPAN_DISPLAY) is best suited to do page-flip on its target platform. Neither API is well documented about their usage and most of the time it really depends on the respective framebuffer driver implementation. * Default ioctl to do page-flip is FBIOPUT_VSCREENINFO. * Set "TARGET_USE_PAN_DISPLAY=true" in board config file to use FBIOPAN_DISPLAY.

2011-01-17gralloc: Add support for 32-bit framebuffers.David 'Digit' Turner
Note: The code under hardware/libhardware/modules/gralloc/ is only used when running the system under the emulator. Change-Id: I022978aeaacc5137c9917cd2ef6952dd3897ece4
2011-01-15gralloc: Fix division-by-0 during system emulation.David 'Digit' Turner
This patch avoids a division-by-0 when the system is running under emulation (the kernel driver reports pixclock as 0, for some reason). Which results in a SIGFPE during the boot sequence. Change-Id: Idb6bcdd58999ea9231f2411481c25929d5d02f1d
2010-10-14Allow disabling page-flipping.Jean-Baptiste Queru
Some devices have low-level bugs in their page-flip. Disabling it at this level gives us more flexibility than trying to control it elsewhere. Bug: 3097357 Change-Id: Icc6ae172264e453bec0680e74a497a2b24299c4a
2009-12-15remove all references to pmem and simplify the lock/unlock hooksMathias Agopian
this gralloc module is only used on the emulator or without a h/w renderer. therefore there is no synchronization to do in lock/unlock and pmem buffers are not relevant. hopefully this will remove some of the confusion about how gralloc should be implemented and make it more obvious that this implementation is not intended to be used by h/w renderers.

2009-05-04lock will now return the vaddr of the buffer. map/umap are gone.Mathias Agopian
- make sure to return an error if a buffer is locked twice or unlocked while not locked. - added registerBuffer() and unregisterBuffer() to the gralloc module so that we can do some cleanup when a buffer is no longer needed. this became necessary after we removed map/unmap so we have a place to unmap buffers without the need of a kernel module. - change the constants for GRALLOC_USAGE_SW_{READ|WRITE}_NEVER to 0, so that NOT specifying them means "NEVER".
