nouveau_bo_init() is backed by ttm_bo_init() and ferries its return code back to the caller. On failures, ttm_bo_init() invokes the provided destructor which should de-initialize and free the memory. Thus, when nouveau_bo_init() returns an error the gem object has already been released and the memory freed by nouveau_bo_del_ttm().

The gbefb driver not only registers a driver but also the device for that driver. This is all well and good when run on the IP32 machines that are supported by the driver but since the driver supports building with COMPILE_TEST we might also be building on other platforms which do not have this hardware and will crash instantiating the driver. Add an IS_ENABLED() check so we compile out the device registration if we don't have the Kconfig option for the machine enabled.

Configurations with both CONFIG_FB_SIMPLE=y and CONFIG_DRM_SIMPLEDRM=m are allowed by Kconfig because the 'depends on !DRM_SIMPLEDRM' dependency does not disallow FB_SIMPLE as long as SIMPLEDRM is not built-in. This can however result in a build failure when cfb_fillrect() etc are then also in loadable modules: x86_64-linux-ld: drivers/video/fbdev/simplefb.o:(.rodata+0x1f8): undefined reference to `cfb_fillrect' x86_64-linux-ld: drivers/video/fbdev/simplefb.o:(.rodata+0x200): undefined reference to `cfb_copyarea' x86_64-linux-ld: drivers/video/fbdev/simplefb.o:(.rodata+0x208): undefined reference to `cfb_imageblit' To work around this, change FB_SIMPLE to be a 'tristate' symbol, which still allows both to be =m together, but not one of them to be =y if the other one is =m. If a distro kernel picks this configuration, it can be determined by local policy which of the two modules gets loaded. The 'of_chosen' export is needed as this is the first loadable module referencing it. Alternatively, the Kconfig dependency could be changed to 'depends on DRM_SIMPLEDRM=n', which would forbid the configuration with both drivers.

After commit 928f9e26 ("clk: fractional-divider: Hide clk_fractional_divider_ops from wide audience") was merged it appears that the DSI panel on my Odroid Go Advance stopped working. Upon closer examination of the problem, it looks like it was the fixup in the rockchip_drm_vop.c file was causing the issue. The changes made to the clk driver appear to change some assumptions made in the fixup. After debugging the working 5.14 kernel and the no-longer working 5.15 kernel, it looks like this was broken all along but still worked, whereas after the fractional clock change it stopped working despite the issue (it went from sort-of broken to very broken). In the 5.14 kernel the dclk_vopb_frac was being requested to be set to 17000999 on my board. The clock driver was taking the value of the parent clock and attempting to divide the requested value from it (17000000/17000999 = 0), then subtracting 1 from it (making it -1), and running it through fls_long to get 64. It would then subtract the value of fd->mwidth from it to get 48, and then bit shift 17000999 to the left by 48, coming up with a very large number of 7649082492112076800. This resulted in a numerator of 65535 and a denominator of 1 from the clk driver. The driver seemingly would try again and get a correct 1:1 value later, and then move on. Output from my 5.14 kernel (with some printfs for good measure): [ 2.830066] rockchip-drm display-subsystem: bound ff460000.vop (ops vop_component_ops) [ 2.839431] rockchip-drm display-subsystem: bound ff450000.dsi (ops dw_mipi_dsi_rockchip_ops) [ 2.855980] Clock is dclk_vopb_frac [ 2.856004] Scale 64, Rate 7649082492112076800, Oldrate 17000999, Parent Rate 17000000, Best Numerator 65535, Best Denominator 1, fd->mwidth 16 [ 2.903529] Clock is dclk_vopb_frac [ 2.903556] Scale 0, Rate 17000000, Oldrate 17000000, Parent Rate 17000000, Best Numerator 1, Best Denominator 1, fd->mwidth 16 [ 2.903579] Clock is dclk_vopb_frac [ 2.903583] Scale 0, Rate 17000000, Oldrate 17000000, Parent Rate 17000000, Best Numerator 1, Best Denominator 1, fd->mwidth 16 Contrast this with 5.15 after the clk change where the rate of 17000999 was getting passed and resulted in numerators/denomiators of 17001/ 17000. Output from my 5.15 kernel (with some printfs added for good measure): [ 2.817571] rockchip-drm display-subsystem: bound ff460000.vop (ops vop_component_ops) [ 2.826975] rockchip-drm display-subsystem: bound ff450000.dsi (ops dw_mipi_dsi_rockchip_ops) [ 2.843430] Rate 17000999, Parent Rate 17000000, Best Numerator 17018, Best Denominator 17017 [ 2.891073] Rate 17001000, Parent Rate 17000000, Best Numerator 17001, Best Denominator 17000 [ 2.891269] Rate 17001000, Parent Rate 17000000, Best Numerator 17001, Best Denominator 17000 [ 2.891281] Rate 17001000, Parent Rate 17000000, Best Numerator 17001, Best Denominator 17000 I have tested the change extensively on my Odroid Go Advance (Rockchip RK3326) and it appears to work well. However, this change will affect all Rockchip SoCs that use this driver so I believe further testing is warranted. Please note that without this change I can confirm at least all PX30s with DSI panels will stop working with the 5.15 kernel. Upon advice from Doug Anderson <dianders@chromium.org> it was decided that we would first check if the clock rate can be set exactly as requested, and only if it could not would we then add 999 to it and attempt the process again. This way we can preserve the behavior for clocks that still need it while resolving the specific issue for the PX30 and DSI panels (since it is using a fractional clock). Changes since v2: - Moved fixes to correct location. Changes since v1: - Made the addition of 999 conditional based on whether the clock subsystem can set the actual clock rate as requested. - Updated the notes in the fixup routine to reflect this new behavior. - Added reference to original commit, as this has technically been broken since then however only now is it an issue due to the clock changes.

We don't currently have any kind of real acceleration on Ampere GPUs, but the TTM memcpy() fallback paths aren't really designed to handle copies between different devices, such as on Optimus systems, and result in a kernel OOPS. A few options were investigated to try and fix this, but didn't work out, and likely would have resulted in a very unpleasant experience for users anyway. This commit adds just enough support for setting up a single channel connected to a copy engine, which the kernel can use to accelerate the buffer copies between devices. Userspace has no access to this incomplete channel support, but it's suitable for TTM's needs. A more complete implementation of host(fifo) for Ampere GPUs is in the works, but the required changes are far too invasive that they would be unsuitable to backport to fix this issue on current kernels. v2: fix GPFIFO length in RAMFC (reported by Karol) Signed-off-by:

Recent rework, which made HDMI PHY driver a platform device, inadvertely reversed clock setup order. HW is very touchy about it. Proper way is to handle controllers resets and clocks first and HDMI PHYs second. Currently, without this fix, first mode set completely fails (nothing on HDMI monitor) on H3 era PHYs. On H6, it still somehow work. Move HDMI PHY reset & clocks handling to sun8i_hdmi_phy_init() which will assure that code is executed after controllers reset & clocks are handled. Additionally, add sun8i_hdmi_phy_deinit() which will deinit them at controllers driver unload. Tested on A64, H3, H6 and R40.

Looks like skl/bxt/derivatives also need the plane stride stretch w/a when using async flips and VT-d is enabled, or else we get corruption on screen.

The objtool warning that the kvm instruction emulation code triggered wasn't very useful: arch/x86/kvm/emulate.o: warning: objtool: __ex_table+0x4: don't know how to handle reloc symbol type: kvm_fastop_exception in that it helpfully tells you which symbol name it had trouble figuring out the relocation for, but it doesn't actually say what the unknown symbol type was that triggered it all. In this case it was because of missing type information (type 0, aka STT_NOTYPE), but on the whole it really should just have printed that out as part of the message. Because if this warning triggers, that's very much the first thing you want to know - why did reloc2sec_off() return failure for that symbol? So rather than just saying you can't handle some type of symbol without saying what the type _was_, just print out the type number too.

Linus Torvalds authored
The recent change to make objtool aware of more symbol relocation types (commit 24ff6525: "objtool: Teach get_alt_entry() about more relocation types") also added another check, and resulted in this objtool warning when building kvm on x86: arch/x86/kvm/emulate.o: warning: objtool: __ex_table+0x4: don't know how to handle reloc symbol type: kvm_fastop_exception The reason seems to be that kvm_fastop_exception() is marked as a global symbol, which causes the relocation to ke kept around for objtool. And at the same time, the kvm_fastop_exception definition (which is done as an inline asm statement) doesn't actually set the type of the global, which then makes objtool unhappy. The minimal fix is to just not mark kvm_fastop_exception as being a global symbol. It's only used in that one compilation unit anyway, so it was always pointless. That's how all the other local exception table labels are done. I'm not entirely happy about the kinds of games that the kvm code plays with doing its own exception handling, and the fact that it confused objtool is most definitely a symptom of the code being a bit too subtle and ad-hoc. But at least this trivial one-liner makes objtool no longer upset about what is going on.

Pull block fixes from Jens Axboe: "A few block fixes for this release: - Revert a BFQ commit that causes breakage for people. Unfortunately it was auto-selected for stable as well, so now 5.14.7 suffers from it too. Hopefully stable will pick up this revert quickly too, so we can remove the issue on that end as well. - Add a quirk for Apple NVMe controllers, which due to their non-compliance broke due to the introduction of command sequences (Keith) - Use shifts in nbd, fixing a __divdi3 issue (Nick)" * tag 'block-5.15-2021-10-01' of git://git.kernel.dk/linux-block: nbd: use shifts rather than multiplies Revert "block, bfq: honor already-setup queue merges" nvme: add command id quirk for apple controllers -

In cachefiles_mark_object_buried, the dentry in question may not have an owner, and thus our cachefiles_object pointer may be NULL when calling the tracepoint, in which case we will also not have a valid debug_id to print in the tracepoint. Check for NULL object in the tracepoint and if so, just set debug_id to MAX_UINT as was done in 2908f5e1 ("fscache: Add a cookie debug ID and use that in traces"). This fixes the following oops: FS-Cache: Cache "mycache" added (type cachefiles) CacheFiles: File cache on vdc registered ...

5.15-rc1 crashes with blank screen when booting up on two ThinkPads using i915. Bisections converge convincingly, but arrive at different and suprising "culprits", none of them the actual culprit. netconsole (with init_netconsole() hacked to call i915_init() when logging has started, instead of by module_init()) tells the story: kernel BUG at drivers/gpu/drm/i915/i915_sw_fence.c:245! with RSI: ffffffff814d408b pointing to sw_fence_dummy_notify(). I've been building with CONFIG_CC_OPTIMIZE_FOR_SIZE=y, and that function needs to be 4-byte aligned. Fixes: 62eaf0ae ("drm/i915/guc: Support request cancellation") Signed-off-by:
