commit 4dfd6486 "drm: Use vblank timestamps to guesstimate how many vblanks were missed" introduced in Linux 4.4-rc1 makes the drm core more fragile to drivers which don't update hw vblank counters and vblank timestamps in sync with firing of the vblank irq and essentially at leading edge of vblank. This exposed a problem with radeon-kms/amdgpu-kms which do not satisfy above requirements: The vblank irq fires a few scanlines before start of vblank, but programmed pageflips complete at start of vblank and vblank timestamps update at start of vblank, whereas the hw vblank counter increments only later, at start of vsync. This leads to problems like off by one errors for vblank counter updates, vblank counters apparently going backwards or vblank timestamps apparently having time going backwards. The net result is stuttering of graphics in games, or little hangs, as well as total failure of timing sensitive applications. See bug #93147 for an example of the regression on Linux 4.4-rc: https://bugs.freedesktop.org/show_bug.cgi?id=93147 This patch tries to align all above events better from the viewpoint of the drm core / of external callers to fix the problem: 1. The apparent start of vblank is shifted a few scanlines earlier, so the vblank irq now always happens after start of this extended vblank interval and thereby drm_update_vblank_count() always samples the updated vblank count and timestamp of the new vblank interval. To achieve this, the reporting of scanout positions by radeon_get_crtc_scanoutpos() now operates as if the vblank starts radeon_crtc->lb_vblank_lead_lines before the real start of the hw vblank interval. This means that the vblank timestamps which are based on these scanout positions will now update at this earlier start of vblank. 2. The driver->get_vblank_counter() function will bump the returned vblank count as read from the hw by +1 if the query happens after the shifted earlier start of the vblank, but before the real hw increment at start of vsync, so the counter appears to increment at start of vblank in sync with the timestamp update. 3. Calls from vblank irq-context and regular non-irq calls are now treated identical, always simulating the shifted vblank start, to avoid inconsistent results for queries happening from vblank irq vs. happening from drm_vblank_enable() or vblank_disable_fn(). 4. The radeon_flip_work_func will delay mmio programming a pageflip until the start of the real vblank iff it happens to execute inside the shifted earlier start of the vblank, so pageflips now also appear to execute at start of the shifted vblank, in sync with vblank counter and timestamp updates. This to avoid some races between updates of vblank count and timestamps that are used for swap scheduling and pageflip execution which could cause pageflips to execute before the scheduled target vblank. The lb_vblank_lead_lines "fudge" value is calculated as the size of the display controllers line buffer in scanlines for the given video mode: Vblank irq's are triggered by the line buffer logic when the line buffer refill for a video frame ends, ie. when the line buffer source read position enters the hw vblank. This means that a vblank irq could fire at most as many scanlines before the current reported scanout position of the crtc timing generator as the number of scanlines the line buffer can maximally hold for a given video mode. This patch has been successfully tested on a RV730 card with DCE-3 display engine and on a evergreen card with DCE-4 display engine, in single-display and dual-display configuration, with different video modes. A similar patch is needed for amdgpu-kms to fix the same problem. Limitations: - Line buffer sizes in pixels are hard-coded on < DCE-4 to a value i just guessed to be high enough to work ok, lacking info on the true sizes atm.

Release the event lock during waits to not delay other outputs in doing their stuff, as the waiting can last up to 200 usecs in some cases.

HPD signals on DVI ports can be fired off before the pins required for DDC probing actually make contact, due to the pins for HPD making contact first. This results in a HPD signal being asserted but DDC probing failing, resulting in hotplugging occasionally failing. This is somewhat rare on most cards (depending on what angle you plug the DVI connector in), but on some cards it happens constantly. The Radeon R5 on the machine used for testing this patch for instance, runs into this issue just about every time I try to hotplug a DVI monitor and as a result hotplugging almost never works. Rescheduling the hotplug work for a second when we run into an HPD signal with a failing DDC probe usually gives enough time for the rest of the connector's pins to make contact, and fixes this issue.

As soon as we leave the spinlock after the job has been added to the job queue, we can no longer rely on the job's data to be available. I have seen a null-pointer dereference due to sched == NULL in amd_sched_wakeup via amd_sched_entity_push_job and amd_sched_ib_submit_kernel_helper. Since the latter initializes sched_job->sched with the address of the ring scheduler, which is guaranteed to be non-NULL, this race appears to be a likely culprit.

It's rare enough not to have hit during testing, since it requires both a device that rejects the first flush, and bad timing while it does that. But since someone did hit it, let's get the revert into 4.4-rc3 so we don't have a released rc with that known issue. Apart from that revert, three other fixes: - From Christoph, a fix for a missing unmap in NVMe request preparation. - An NVMe fix from Nishanth that fixes data corruption on powerpc. - Also from Christoph, fix a list_del() attempt on blk-mq that didn't have a matching list_add() at timer start" * 'for-linus' of git://git.kernel.dk/linux-block: Revert "blk-flush: Queue through IO scheduler when flush not required" block: fix blk_abort_request for blk-mq drivers nvme: add missing unmaps in nvme_queue_rq NVMe: default to 4k device page size

This reverts commit 1b2ff19e. Jan writes: -- Thanks for report! After some investigation I found out we allocate elevator specific data in __get_request() only for non-flush requests. And this is actually required since the flush machinery uses the space in struct request for something else. Doh. So my patch is just wrong and not easy to fix since at the time __get_request() is called we are not sure whether the flush machinery will be used in the end. Jens, please revert 1b2ff19e. Thanks! I'm somewhat surprised that you can reliably hit the race where flushing gets disabled for the device just while the request is in flight. But I guess during boot it makes some sense. -- So let's just revert it, we can fix the queue run manually after the fact. This race is rare enough that it didn't trigger in testing, it requires the specific disable-while-in-flight scenario to trigger.

This patch removes the vpid check when emulating nested invvpid instruction of type all-contexts invalidation. The existing code is incorrect because: (1) According to Intel SDM Vol 3, Section "INVVPID - Invalidate Translations Based on VPID", invvpid instruction does not check vpid in the invvpid descriptor when its type is all-contexts invalidation. (2) According to the same document, invvpid of type all-contexts invalidation does not require there is an active VMCS, so/and get_vmcs12() in the existing code may result in a NULL-pointer dereference. In practice, it can crash both KVM itself and L1 hypervisors that use invvpid (e.g. Xen). Signed-off-by: NHaozhong Zhang <haozhong.zhang@intel.com> Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

There's a few places where we need to access a GPC register from ucode, but outside of the falcon's io address space. To do this we need to calculate the offset based on which GPC we're executing on. This used to be done manually, but we've since found a "base" offset that can be added by the hardware. To use this, an extra bit needs to be set in the register address, which is what this macro achieves. There should be no functional change from this commit.

由 Nishanth Aravamudan 提交于
We received a bug report recently when DDW (64-bit direct DMA on Power) is not enabled for NVMe devices. In that case, we fall back to 32-bit DMA via the IOMMU, which is always done via 4K TCEs (Translation Control Entries). The NVMe device driver, though, assumes that the DMA alignment for the PRP entries will match the device's page size, and that the DMA aligment matches the kernel's page aligment. On Power, the the IOMMU page size, as mentioned above, can be 4K, while the device can have a page size of 8K, while the kernel has a page size of 64K. This eventually trips the BUG_ON in nvme_setup_prps(), as we have a 'dma_len' that is a multiple of 4K but not 8K (e.g., 0xF000). In this particular case of page sizes, we clearly want to use the IOMMU's page size in the driver. And generally, the NVMe driver in this function should be using the IOMMU's page size for the default device page size, rather than the kernel's page size. There is not currently an API to obtain the IOMMU's page size across all architectures and in the interest of a stop-gap fix to this functional issue, default the NVMe device page size to 4K, with the intent of adding such an API and implementation across all architectures in the next merge window. With the functionally equivalent v3 of this patch, our hardware test exerciser survives when using 32-bit DMA; without the patch, the kernel will BUG within a few minutes.
