Note though I'm not entirely clear on this - on one of the machines where this issue was observed, I also noticed that we appeared to be rejecting the VBT defined backlight frequency in intel_dp_aux_vesa_calc_max_backlight(). It's noted in this function that: /* Use highest possible value of Pn for more granularity of brightness * adjustment while satifying the conditions below. * ... * - FxP is within 25% of desired value. * Note: 25% is arbitrary value and may need some tweak. */ So it's possible that this value might just need to be tweaked, but for now let's just disable the VESA backlight interface unless it's specified in the VBT just to be safe. We might be able to try enabling this again by default in the future.

I've managed to reproduce this without rebooting by doing: chvt 3; echo 1 > /sys/class/graphics/fb0/blank;\ echo 0 > /sys/class/graphics/fb0/blank Which rapidly turns the panel off and back on again. The vlv_dsi.c code uses an intel_dsi_msleep() helper for the various delays used for panel on/off, since starting with MIPI-sequences version >= 3 the delays are already included inside the MIPI-sequences. The problems exposed by the "Shut down displays gracefully on reboot" change, show that using this helper for the panel_pwr_cycle_delay is not the right thing to do. This has not been noticed until now because normally the panel never is cycled off and directly on again in quick succession. Change the msleep for the panel_pwr_cycle_delay to a normal msleep() call to avoid the panel staying black after a quick off + on cycle.

However, it got messed up at some point and mdev code was put in gvt.c and is pretending to be "generic" by masquerading as some generic attribute list: static MDEV_TYPE_ATTR_RO(description); But MDEV_TYPE attributes are only usable with mdev_device, nothing else. Ideally all of this would be moved to kvmgt.c, but it is entangled with the rest of the "generic" code in an odd way. Thus put in a kconfig dependency so we don't get randconfig failures when the next patch creates a link time dependency related to the use of MDEV_TYPE.

It stems from the root kobject method: ssize_t (*show)(struct kobject *kobj, struct kobj_attribute *attr,..) Each subclass of kobject should provide their own function with the same signature but more specific types, eg struct device uses: ssize_t (*show)(struct device *dev, struct device_attribute *attr,..) In this case the existing signature is: ssize_t (*show)(struct kobject *kobj, struct device *dev,..) Where kobj is a 'struct mdev_type *' and dev is 'mdev_type->parent->dev'. Change the mdev_type related sysfs attribute functions to: ssize_t (*show)(struct mdev_type *mtype, struct mdev_type_attribute *attr,..) In order to restore type safety and match the driver core standard There are no current users of 'attr', but if it is ever needed it would be hard to add in retroactively, so do it now.

The %llu will consume the "0" in "0x" of your input, and the hex value you think you're entering will always be 0. That is, a valid hex value can never be consumed. On the other hand, just entering a hex number without leading 0x will either be scanned as a string and not match, for instance FAB123, or the leading decimal portion is scanned as the %llu, for instance 123FAB will be scanned as 123, which is not correct. Thus remove the first %llu scan and leave only the %llx scan, removing the leading 0x since %llx can scan either. Addresses are usually always hex values, so this suffices.

The "bad_page_cnt_threshold" is a dynamically computed value. It depends on three things: the VRAM size; the size of the EEPROM (or the size allocated to the RAS table therein); and the "bad_page_threshold" module parameter. It is a dynamically computed value, when the amdgpu module is run, on which further parameters and logic depend, and as such it is helpful to see the dynamically computed value in debugfs.

In particular the driver should perform the link training sequence steps even in case of an AUX failure, as this sequence also includes port initialization steps. Not doing that can leave the port/pipe in a broken state and lead for instance to a flip done timeout. Fix this by continuing with link training (in a no-LTTPR mode) if the DPRX DPCD readout failed for some reason at the beginning of link training. After a successful connector detection we already have the DPCD read out and cached, so the failed repeated read for it should not cause a problem. Note that a partial AUX read could in theory partly overwrite the cached DPCD (and return error) but this overwrite should not happen if the returned values are corrupted (due to a timeout or some other IO error). Kudos to Ville to root cause the problem.

Both of them cause what seem to be valid warnings in the kernel, where we have array size mismatches in function arguments (that are no longer just silently converted to a pointer to element, but actually checked). This fixes most of the trivial ones, by making the function declaration match the function definition, and in the case of intel_pm.c, removing the over-specified array size from the argument declaration. At least one 'stringop-overread' warning remains in the i915 driver, but that one doesn't have the same obvious trivial fix, and may or may not actually be indicative of a bug.

However old logic was using: rate = pixel clock / (h * v / 1000). When the h/v total is invalid, like all 0, h * v / 1000 will be rounded to 0, which leads to a divided by 0 fault. 0 H/V are already checked above. Instead of divide after divide, refine the calculation to divide after multiply: "pixel clock * 1000 / (h * v)" Guest driver should guarantee the correctness of the timing regs' value.

If the userspace is not enabling the cursor, they can use multiple planes as they please. Nevertheless, we start to have constraints when userspace tries to enable hardware cursor with various planes. Basically, we cannot draw the cursor at the same size and position on two separated pipes since it uses extra bandwidth and DML only run with one cursor. For those reasons, when we enable hardware cursor and multiple planes, our driver should accept variations like the ones described below: +-------------+ +--------------+ | +---------+ | | | | |Primary | | | Primary | | | | | | Overlay | | +---------+ | | | |Overlay | | | +-------------+ +--------------+ In this scenario, we can have the desktop UI in the overlay and some other framebuffer attached to the primary plane (e.g., video). However, userspace needs to obey some rules and avoid scenarios like the ones described below (when enabling hw cursor): +--------+ |Overlay | +-------------+ +-----+-------+ +-| |--+ | +--------+ | +--------+ | | +--------+ | | |Overlay | | |Overlay | | | | | | | | | | | | | | +--------+ | +--------+ | | | | Primary | | Primary | | Primary | +-------------+ +-------------+ +-------------+ +-------------+ +-------------+ | +--------+ | Primary | | |Overlay | | | | | | | | | +--------+ | +--------+ | | Primary | | |Overlay | | +-------------+ +-| |--+ +--------+ If the userspace violates some of the above scenarios, our driver needs to reject the commit; otherwise, we can have unexpected behavior. Since we don't have a proper driver validation for the above case, we can see some problems like a duplicate cursor in applications that use multiple planes. This commit fixes the cursor issue and others by adding adequate verification for multiple planes. Change since V1 (Harry and Sean): - Remove cursor verification from the equation.

There is a TODO about DCC alignment, but it isn't worse than before and I'd need to dig a bunch into the specifics. Getting this out in a reasonable timeframe to make sure it gets the appropriate testing seemed more important. Finally as I've found that debugging addfb2 failures is a pita I was generous adding explicit error messages to every failure case.

I recently receive a patch to explicitly add a new one. Let's do treewide cleanups, otherwise some people follow the existing code and attempt to upstream their favoriate editor setups. It is even nicer if scripts/checkpatch.pl can check it. If we like to impose coding style in an editor-independent manner, I think editorconfig (patch [1]) is a saner solution.
