[PATCH v2 1/4] drm/i915: Add support for panels with VESA backlights with PWM enable/disable

by Lyude Paul

This simply adds proper support for panel backlights that can be controlled via VESA's backlight control protocol, but which also require that we enable and disable the backlight via PWM instead of via the DPCD interface. We also enable this by default, in order to fix some people's backlights that were broken by not having this enabled. For reference, backlights that require this and use VESA's backlight interface tend to be laptops with hybrid GPUs, but this very well may change in the future.

[PATCH] drm/brdige: analogix_dp: Grab runtime PM reference for DP-AUX

by Brian Norris

If the display is not enable()d, then we aren't holding a runtime PM reference here. Thus, it's easy to accidentally cause a hang, if user space is poking around at /dev/drm_dp_aux0 at the "wrong" time. Let's get the panel and PM state right before trying to talk AUX.

[PATCH 11/13] PCI: aardvark: Fix link training

by Marek Behún

From: Pali Rohár <pali(a)kernel.org> Fix multiple link training issues in aardvark driver. The main reason of these issues was misunderstanding of what certain registers do, since their names and comments were misleading: before commit 96be36dbffac ("PCI: aardvark: Replace custom macros by standard linux/pci_regs.h macros"), the pci-aardvark.c driver used custom macros for accessing standard PCIe Root Bridge registers, and misleading comments did not help to understand what the code was really doing. After doing more tests and experiments I've come to the conclusion that the SPEED_GEN register in aardvark sets the PCIe revision / generation compliance and forces maximal link speed. Both GEN3 and GEN2 values set the read-only PCI_EXP_FLAGS_VERS bits (PCIe capabilities version of Root Bridge) to value 2, while GEN1 value sets PCI_EXP_FLAGS_VERS to 1, which matches with PCI Express specifications revisions 3, 2 and 1 respectively. Changing SPEED_GEN also sets the read-only bits PCI_EXP_LNKCAP_SLS and PCI_EXP_LNKCAP2_SLS to corresponding speed. (Note that PCI Express rev 1 specification does not define PCI_EXP_LNKCAP2 and PCI_EXP_LNKCTL2 registers and when SPEED_GEN is set to GEN1 (which also sets PCI_EXP_FLAGS_VERS set to 1), lspci cannot access PCI_EXP_LNKCAP2 and PCI_EXP_LNKCTL2 registers.) Changing PCIe link speed can be done via PCI_EXP_LNKCTL2_TLS bits of PCI_EXP_LNKCTL2 register. Armada 3700 Functional Specifications says that the default value of PCI_EXP_LNKCTL2_TLS is based on SPEED_GEN value, but tests showed that the default value is always 8.0 GT/s, independently of speed set by SPEED_GEN. So after setting SPEED_GEN, we must also set value in PCI_EXP_LNKCTL2 register via PCI_EXP_LNKCTL2_TLS bits. Triggering PCI_EXP_LNKCTL_RL bit immediately after setting LINK_TRAINING_EN bit actually doesn't do anything. Tests have shown that a delay is needed after enabling LINK_TRAINING_EN bit. As triggering PCI_EXP_LNKCTL_RL currently does nothing, remove it. Commit 43fc679ced18 ("PCI: aardvark: Improve link training") introduced code which sets SPEED_GEN register based on negotiated link speed from PCI_EXP_LNKSTA_CLS bits of PCI_EXP_LNKSTA register. This code was added to fix detection of Compex WLE900VX (Atheros QCA9880) WiFi GEN1 PCIe cards, as otherwise these cards were "invisible" on PCIe bus (probably because they crashed). But apparently more people reported the same issues with these cards also with other PCIe controllers [1] and I was able to reproduce this issue also with other "noname" WiFi cards based on Atheros QCA9890 chip (with the same PCI vendor/device ids as Atheros QCA9880). So this is not an issue in aardvark but rather an issue in Atheros QCA98xx chips. Also, this issue only exists if the kernel is compiled with PCIe ASPM support, and a generic workaround for this is to change PCIe Bridge to 2.5 GT/s link speed via PCI_EXP_LNKCTL2_TLS_2_5GT bits in PCI_EXP_LNKCTL2 register [2], before triggering PCI_EXP_LNKCTL_RL bit. This workaround also works when SPEED_GEN is set to value GEN2 (5 GT/s). So remove this hack completely in the aardvark driver and always set SPEED_GEN to value from 'max-link-speed' DT property. Fix for Atheros QCA98xx chips is handled separately by patch [2]. These two things (code for triggering PCI_EXP_LNKCTL_RL bit and changing SPEED_GEN value) also explain why commit 6964494582f5 ("PCI: aardvark: Train link immediately after enabling training") somehow fixed detection of those problematic Compex cards with Atheros chips: if triggering link retraining (via PCI_EXP_LNKCTL_RL bit) was done immediately after enabling link training (via LINK_TRAINING_EN), it did nothing. If there was a specific delay, aardvark HW already initialized PCIe link and therefore triggering link retraining caused the above issue. Compex cards triggered link down event and disappeared from the PCIe bus. Commit f4c7d053d7f7 ("PCI: aardvark: Wait for endpoint to be ready before training link") added 100ms sleep before calling 'Start link training' command and explained that it is a requirement of PCI Express specification. But the code after this 100ms sleep was not doing 'Start link training', rather it triggered PCI_EXP_LNKCTL_RL bit via PCIe Root Bridge to put link into Recovery state. The required delay after fundamental reset is already done in function advk_pcie_wait_for_link() which also checks whether PCIe link is up. So after removing the code which triggers PCI_EXP_LNKCTL_RL bit on PCIe Root Bridge, there is no need to wait 100ms again. Remove the extra msleep() call and update comment about the delay required by the PCI Express specification. According to Marvell Armada 3700 Functional Specifications, Link training should be enabled via aardvark register LINK_TRAINING_EN after selecting PCIe generation and x1 lane. There is no need to disable it prior resetting card via PERST# signal. This disabling code was introduced in commit 5169a9851daa ("PCI: aardvark: Issue PERST via GPIO") as a workaround for some Atheros cards. It turns out that this also is Atheros specific issue and affects any PCIe controller, not only aardvark. Moreover this Atheros issue was triggered by juggling with PCI_EXP_LNKCTL_RL, LINK_TRAINING_EN and SPEED_GEN bits interleaved with sleeps. Now, after removing triggering PCI_EXP_LNKCTL_RL, there is no need to explicitly disable LINK_TRAINING_EN bit. So remove this code too. The problematic Compex cards described in previous git commits are correctly detected in advk_pcie_train_link() function even after applying all these changes. Note that with this patch, and also prior this patch, some NVMe disks which support PCIe GEN3 with 8 GT/s speed are negotiated only at the lowest link speed 2.5 GT/s, independently of SPEED_GEN value. After manually triggering PCI_EXP_LNKCTL_RL bit (e.g. from userspace via setpci), these NVMe disks change link speed to 5 GT/s when SPEED_GEN was configured to GEN2. This issue first needs to be properly investigated. I will send a fix in the future. On the other hand, some other GEN2 PCIe cards with 5 GT/s speed are autonomously by HW autonegotiated at full 5 GT/s speed without need of any software interaction. Armada 3700 Functional Specifications describes the following steps for link training: set SPEED_GEN to GEN2, enable LINK_TRAINING_EN, poll until link training is complete, trigger PCI_EXP_LNKCTL_RL, poll until signal rate is 5 GT/s, poll until link training is complete, enable ASPM L0s. The requirement for triggering PCI_EXP_LNKCTL_RL can be explained by the need to achieve 5 GT/s speed (as changing link speed is done by throw to recovery state entered by PCI_EXP_LNKCTL_RL) or maybe as a part of enabling ASPM L0s (but in this case ASPM L0s should have been enabled prior PCI_EXP_LNKCTL_RL). It is unknown why the original pci-aardvark.c driver was triggering PCI_EXP_LNKCTL_RL bit before waiting for the link to be up. This does not align with neither PCIe base specifications nor with Armada 3700 Functional Specification. (Note that in older versions of aardvark, this bit was called incorrectly PCIE_CORE_LINK_TRAINING, so this may be the reason.) It is also unknown why Armada 3700 Functional Specification says that it is needed to trigger PCI_EXP_LNKCTL_RL for GEN2 mode, as according to PCIe base specification 5 GT/s speed negotiation is supposed to be entirely autonomous, even if initial speed is 2.5 GT/s.

[PATCH 05/13] PCI: aardvark: Fix configuring Reference clock

by Marek Behún

From: Pali Rohár <pali(a)kernel.org> Commit 366697018c9a ("PCI: aardvark: Add PHY support") introduced configuration of PCIe Reference clock via PCIE_CORE_REF_CLK_REG register, but did it incorrectly. PCIe Reference clock differential pair is routed from system board to endpoint card, so on CPU side it has output direction. Therefore it is required to enable transmitting and disable receiving. Default configuration according to Armada 3700 Functional Specifications is enabled receiver part and disabled transmitter. We need this change because otherwise PCIe Reference clock is configured to some undefined state when differential pair is used for both transmitting and receiving. Fix this by disabling receiver part.

[PATCH] drm/msm: Avoid potential overflow in timeout_to_jiffies()

by Marek Vasut

The return type of ktime_divns() is s64. The timeout_to_jiffies() currently assigns the result of this ktime_divns() to unsigned long, which on 32 bit systems may overflow. Furthermore, the result of this function is sometimes also passed to functions which expect signed long, dma_fence_wait_timeout() is one such example. Fix this by adjusting the type of remaining_jiffies to s64, so we do not suffer overflow there, and return a value limited to range of 0..INT_MAX, which is safe for all usecases of this timeout. The above overflow can be triggered if userspace passes in too large timeout value, larger than INT_MAX / HZ seconds. The kernel detects it and complains about "schedule_timeout: wrong timeout value %lx" and generates a warning backtrace. Note that this fixes commit 6cedb8b377bb ("drm/msm: avoid using 'timespec'"), because the previously used timespec_to_jiffies() function returned unsigned long instead of s64: static inline unsigned long timespec_to_jiffies(const struct timespec *value) Fixes: 6cedb8b377bb ("drm/msm: avoid using 'timespec'") Signed-off-by: Marek Vasut <marex(a)denx.de> Cc: Arnd Bergmann <arnd(a)arndb.de> Cc: Jordan Crouse <jcrouse(a)codeaurora.org> Cc: Rob Clark <robdclark(a)chromium.org> Cc: stable(a)vger.kernel.org # 5.6+ --- NOTE: This is related to Mesa MR https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/12886 --- drivers/gpu/drm/msm/msm_drv.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/msm/msm_drv.h b/drivers/gpu/drm/msm/msm_drv.h index 0b2686b060c73..d96b254b8aa46 100644 --- a/drivers/gpu/drm/msm/msm_drv.h +++ b/drivers/gpu/drm/msm/msm_drv.h @@ -543,7 +543,7 @@ static inline int align_pitch(int width, int bpp) static inline unsigned long timeout_to_jiffies(const ktime_t *timeout) { ktime_t now = ktime_get(); - unsigned long remaining_jiffies; + s64 remaining_jiffies; if (ktime_compare(*timeout, now) < 0) { remaining_jiffies = 0; @@ -552,7 +552,7 @@ static inline unsigned long timeout_to_jiffies(const ktime_t *timeout) remaining_jiffies = ktime_divns(rem, NSEC_PER_SEC / HZ); } - return remaining_jiffies; + return clamp(remaining_jiffies, 0LL, (s64)INT_MAX); } #endif /* __MSM_DRV_H__ */ -- 2.33.0

[PATCH] binder: use cred instead of task for selinux checks

by Todd Kjos

Save the struct cred associated with a binder process at initial open to avoid potential race conditions when converting to a security ID. Since binder was integrated with selinux, it has passed 'struct task_struct' associated with the binder_proc to represent the source and target of transactions. The conversion of task to SID was then done in the hook implementations. It turns out that there are race conditions which can result in an incorrect security context being used. Fix by saving the 'struct cred' during binder_open and pass it to the selinux subsystem. Fixes: 79af73079d75 ("Add security hooks to binder and implement the hooks for SELinux.")
