fbdev: Add initializer macros for struct fb_ops

2023-06-01T10:26:45Z

For framebuffers in I/O and system memory, add macros that set struct fb_ops to the respective callback functions. For deferred I/O, add macros that generate callback functions with damage handling. Add initializer macros that set struct fb_ops to the generated callbacks. These macros can remove a lot boilerplate code from fbdev drivers. The drivers are supposed to use the macro that is required for its framebuffer. Each macro is split into smaller helpers, so that drivers with non-standard callbacks can pick and customize callbacks as needed. There are individual helper macros for read/write, mmap and drawing. v5: * fix whitespace errors (Jingfeng) Signed-off-by: Thomas Zimmermann Reviewed-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20230530151228.22979-3-tzimmermann@suse.de

fbdev: Move framebuffer I/O helpers into

2023-05-18T09:07:25Z

Implement framebuffer I/O helpers, such as fb_read*() and fb_write*(), in the architecture's header file or the generic one. The common case has been the use of regular I/O functions, such as __raw_readb() or memset_io(). A few architectures used plain system- memory reads and writes. Sparc used helpers for its SBus. The architectures that used special cases provide the same code in their __raw_*() I/O helpers. So the patch replaces this code with the __raw_*() functions and moves it to for all architectures. v8: * remove garbage after commit-message tags v6: * fix fb_readq()/fb_writeq() on 64-bit mips (kernel test robot) v5: * include in ; fix s390 build v4: * ia64, loongarch, sparc64: add fb_mem*() to arch headers to keep current semantics (Arnd) v3: * implement all architectures with generic helpers * support reordering and native byte order (Geert, Arnd) Signed-off-by: Thomas Zimmermann Tested-by: Sui Jingfeng Reviewed-by: Arnd Bergmann Link: https://patchwork.freedesktop.org/patch/msgid/20230512102444.5438-7-tzimmermann@suse.de

fbdev: Move I/O read and write code into helper functions

2023-05-08T13:28:34Z

Move the existing I/O read and write code for I/O memory into the new helpers fb_cfb_read() and fb_cfb_write(). Make them the default fp_ops. No functional changes. In the near term, the new functions will be useful to the DRM subsystem, which currently provides it's own implementation. It can then use the shared code. In the longer term, it might make sense to revise the I/O helper's default status and make them opt-in by the driver. Systems that don't use them would not contain the code any longer. v2: * add detailed commit message (Javier) * rename fb_cfb_() to fb_io_() (Geert) * add fixes that got lost while moving the code (Geert) Signed-off-by: Thomas Zimmermann Tested-by: Sui Jingfeng Reviewed-by: Javier Martinez Canillas Acked-by: Helge Deller Reviewed-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20230428122452.4856-19-tzimmermann@suse.de

fbdev: Fix incorrect page mapping clearance at fb_deferred_io_release()

2023-03-10T13:13:02Z

The recent fix for the deferred I/O by the commit 3efc61d95259 ("fbdev: Fix invalid page access after closing deferred I/O devices") caused a regression when the same fb device is opened/closed while it's being used. It resulted in a frozen screen even if something is redrawn there after the close. The breakage is because the patch was made under a wrong assumption of a single open; in the current code, fb_deferred_io_release() cleans up the page mapping of the pageref list and it calls cancel_delayed_work_sync() unconditionally, where both are no correct behavior for multiple opens. This patch adds a refcount for the opens of the device, and applies the cleanup only when all files get closed. As both fb_deferred_io_open() and _close() are called always in the fb_info lock (mutex), it's safe to use the normal int for the refcounting. Also, a useless BUG_ON() is dropped.
