Also remove the error return value. That's all errors for either driver bugs (trying to unbind something that isn't bound), or errors of the new driver that will take over. There's nothing the outgoing driver can do about this anyway, so switch over to void. Signed-off-by:

Ever since commit c47747fd Author: Linus Torvalds <torvalds@linux-foundation.org> Date: Wed May 11 14:58:34 2011 -0700 fbmem: make read/write/ioctl use the frame buffer at open time fbdev has gained proper refcounting for the fbinfo attached to any open files, which means that the backing driver (stored in fb_info->fbops) cannot untimely disappear anymore. The only thing that can happen is that the entire device just outright disappears and gets unregistered, but file_fb_info does check for that. Except that it's racy - it only checks once at the start of a file_ops, there's no guarantee that the underlying fbdev won't untimely disappear. Aside: A proper way to fix that race is probably to replicate the srcu trickery we've rolled out in drm. But given that this race has existed since forever it's probably not one we need to fix right away. do_unregister_framebuffer also nowhere clears fb_info->fbops, hence the check in lock_fb_info can't possible catch a disappearing fbdev later on. Long story short: Ever since the above commit the fb_info->fbops checks have essentially become dead code. Remove this all. Aside from the file_ops callbacks, and stuff called from there there's only register/unregister code left. If that goes wrong a driver managed to register/unregister a device instance twice or in the wrong order. That's just a driver bug. v2: - fb_mmap had an open-coded version of the fbinfo->fops check, because it doesn't need the fbinfo->lock. Delete that too. - Use the wrapper function in fb_open/release now, since no difference anymore. Signed-off-by:

Simply because olpc never unregisters the damn thing. It also registers the framebuffer directly by poking around in fbdev core internals, so it's all around rather broken. Signed-off-by:

With commit 6104c370 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Aug 1 17:32:07 2017 +0200 fbcon: Make fbcon a built-time depency for fbdev we have a static dependency between fbcon and fbdev, and we can replace the indirection through the notifier chain with a function call. v2: Sam Ravnborg noticed that mach-pxa/am200epd.c has a notifier too, and listens to this. ... Looking at the code it seems to wait for some fb to show up, so that it can get the framebuffer base address from the fb_info struct. I suspect his is some firmware fbdev. Then it uses that information to let the real fbdev driver (metronomefb.c by the looks) get at the framebuffer memory. This doesn't looke like it's easy to fix (except by deleting the entire thing, seems untouched since 2008, we might be able to get away with that), so let's just stuff a few #ifdef into fb.h and fbmem.c and cry over them for a bit.

This is unused code since commit 6104c370 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Aug 1 17:32:07 2017 +0200 fbcon: Make fbcon a built-time depency for fbdev when fbcon was made a compile-time static dependency of fbdev. We can't exit fbcon anymore without exiting fbdev first, which only works if all fbdev drivers have unloaded already. Hence this is all dead code. v2: I missed that fbcon_exit is also called from con_deinit stuff, and there fbcon_has_exited prevents double-cleanup. But we can fix that by properly resetting con2fb_map[] to all -1, which is used everywhere else to indicate "no fb_info allocate to this console". With that change the double-cleanup (which resulted in a module refcount underflow, among other things) is prevented. Aside: con2fb_map is a signed char, so don't register more than 128 fb_info or hilarity will ensue. v3: CI showed me that I still didn't fully understand what's going on here. The leaked references in con2fb_map have been used upon rebinding the fb console in fbcon_init. It worked because fbdev unregistering still cleaned out con2fb_map, and reset it to info_idx. If the last fbdev driver unregistered, then it also reset info_idx, and unregistered the fbcon driver. Imo that's all a bit fragile, so let's keep the con2fb_map reset to -1, and in fbcon_init pick info_idx if we're starting fresh. That means unbinding and rebinding will cleanse the mapping, but why are you doing that if you want to retain the mapping, so should be fine. Also, I think info_idx == -1 is impossible in fbcon_init - we unregister the fbcon in that case. So catch&warn about that. v4: Drop unecessary assignment - I forgot to delete the first assignment of info in fbcon_init. Cc: Sam Ravnborg <sam@ravnborg.org> Reviewed-by:

I honestly have no idea what the subtle differences between con_is_visible, con_is_fg (internal to vt.c) and con_is_bound are. But it looks like both vc->vc_display_fg and con_driver_map are protected by the console_lock, so probably better if we hold that when checking this. To do that I had to deinline the con_is_visible function. Signed-off-by:

This driver does not support reading more than 255 bytes at once because the register for storing the number of bytes to read is only 8 bits. Add a max_read_len quirk to enforce this. This was found when using this driver with the SFP driver, which was previously reading all 256 bytes in the SFP EEPROM in one transaction. This caused a bunch of hard-to-debug errors in the xiic driver since the driver/logic was treating the number of bytes to read as zero. Rejecting transactions that aren't supported at least allows the problem to be diagnosed more easily. Signed-off-by:

The lockref cmpxchg loop is unbound as long as the spinlock is not taken. Depending on the hardware implementation of compare-and-swap a high number of loop retries might happen. Add an upper bound to the loop to force the fallback to spinlocks after some time. A retry value of 100 should not impact any hardware that does not have this issue. With the retry limit the performance of an open-close testcase improved between 60-70% on ThunderX2. Suggested-by:
