fbcon_screen_pos() performs the same as the default implementation. The only difference in the default implementation is that is considers both vc->vc_origin and vc->vc_visible_origin. But given fbcon's softscroll code was already removed in commit 50145474f6ef (fbcon: remove soft scrollback code), both are always the same. So remove fbcon_screen_pos() too.

2024-01-28tty: vt: pass vc_resize_user as a parameterJiri Slaby (SUSE)1-1/+1
It is pretty unfortunate to set vc_data::vc_resize_user in two callers of vc_do_resize(). vc_resize_user is immediately reset there (while remembering it). So instead of this back and forth, pass 'from_user' as a parameter. Notes on 'int user': * The name changes from 'user' to 'from_user' on some places to be consistent. * The type is bool now as 'int user' might evoke user's uid or whatever. Provided vc_resize() is called on many places and they need not to care about this parameter, its prototype is kept unchanged. Instead, it is now an inline calling a new __vc_resize() which implements the above. This patch makes the situation much more obvious.

2024-01-12fbdev: flush deferred IO before closingNam Cao1-1/+1
When framebuffer gets closed, the queued deferred IO gets cancelled. This can cause some last display data to vanish. This is problematic for users who send a still image to the framebuffer, then close the file: the image may never appear. To ensure none of display data get lost, flush the queued deferred IO first before closing. Another possible solution is to delete the cancel_delayed_work_sync() instead. The difference is that the display may appear some time after closing. However, the clearing of page mapping after this needs to be removed too, because the page mapping is used by the deferred work. It is not completely obvious whether it is okay to not clear the page mapping. For a patch intended for stable trees, go with the simple and obvious solution.

2024-01-12fbdev: flush deferred work in fb_deferred_io_fsync()Nam Cao1-5/+1
The driver's fsync() is supposed to flush any pending operation to hardware. It is implemented in this driver by cancelling the queued deferred IO first, then schedule it for "immediate execution" by calling schedule_delayed_work() again with delay=0. However, setting delay=0 only means the work is scheduled immediately, it does not mean the work is executed immediately. There is no guarantee that the work is finished after schedule_delayed_work() returns. After this driver's fsync() returns, there can still be pending work. Furthermore, if close() is called by users immediately after fsync(), the pending work gets cancelled and fsync() may do nothing. To ensure that the deferred IO completes, use flush_delayed_work() instead. Write operations to this driver either write to the device directly, or invoke schedule_delayed_work(); so by flushing the workqueue, it can be guaranteed that all previous writes make it to the device.

2023-11-29fbdev: Push pgprot_decrypted() into mmap implementationsThomas Zimmermann2-5/+2
If a driver sets struct fb_ops.fb_mmap, the fbdev core automatically calls pgprot_decrypted(). But the default fb_mmap code doesn't handle pgprot_decrypted(). Move the call to pgprot_decrypted() into each drivers' fb_mmap function. This only concerns fb_mmap functions for system and DMA memory. For I/O memory, which is the default case, nothing changes. The fb_mmap for I/O-memory can later be moved into a helper as well. DRM's fbdev emulation handles pgprot_decrypted() internally via the Prime helpers. Fbdev doesn't have to do anything in this case. In cases where DRM uses deferred I/O, this patch updates fb_mmap correctly.

2023-09-18drm: fix up fbdev Kconfig defaultsArnd Bergmann1-1/+1
As a result of the recent Kconfig reworks, the default settings for the framebuffer interfaces changed in unexpected ways: Configurations that leave CONFIG_FB disabled but use DRM now get DRM_FBDEV_EMULATION by default. This also turns on the deprecated /dev/fb device nodes for machines that don't actually want it. In turn, configurations that previously had DRM_FBDEV_EMULATION enabled now only get the /dev/fb front-end but not the more useful framebuffer console, which is not selected any more. We had previously decided that any combination of the three frontends (FB_DEVICE, FRAMEBUFFER_CONSOLE and LOGO) should be selectable, but the new default settings mean that a lot of defconfig files would have to get adapted. Change the defaults back to what they were in Linux 6.5: - Leave DRM_FBDEV_EMULATION turned off unless CONFIG_FB is enabled. Previously this was a hard dependency but now the two are independent. However, configurations that enable CONFIG_FB probably also want to keep the emulation for DRM, while those without FB presumably did that intentionally in the past. - Leave FB_DEVICE turned off for FB=n. Following the same logic, the deprecated option should not automatically get enabled here, most users that had FB turned off in the past do not want it, even if they want the console - Turn the FRAMEBUFFER_CONSOLE option on if DRM_FBDEV_EMULATION is set to avoid having to change defconfig files that relied on it being selected unconditionally in the past. This also makes sense since both LOGO and FB_DEVICE are now disabled by default for builds without CONFIG_FB, but DRM_FBDEV_EMULATION would make no sense if all three are disabled.
