2024-09-03drm/i915/display: Add mechanism to use sink model when applying quirkJouni Högander
Currently there is no way to apply quirk on device only if certain panel model is installed. This patch implements such mechanism by adding new quirk type intel_dpcd_quirk which contains also sink_oui and sink_device_id fields and using also them to figure out if applying quirk is needed. New intel_init_dpcd_quirks is added and called after drm_dp_read_desc with proper sink device identity read from dpcdc. v3: - !mem_is_zero fixed to mem_is_zero v2: - instead of using struct intel_quirk add new struct intel_dpcd_quirk Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240902064241.1020965-2-jouni.hogander@intel.com (cherry picked from commit b3b91369908ac63be6f64905448b8ba5cd151875) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>

[Why] DCN IPS interoperates with other system idle power features, such as Zstates. On DCN35, there is a known issue where system Z8 + DCN IPS2 causes a hard hang. We observe this on systems where the SBIOS allows Z8. Though there is a SBIOS fix, there's no guarantee that users will get it any time soon, or even install it. A workaround is needed to prevent this from rearing its head in the wild. [How] For DCN35, check the pmfw version to determine whether the SBIOS has the fix. If not, set IPS1+RCG as the deepest possible state in all cases except for s0ix and display off (DPMS).

2024-09-02ACPI: CPPC: Fix MASK_VAL() usageClément Léger
MASK_VAL() was added as a way to handle bit_offset and bit_width for registers located in system memory address space. However, while suited for reading, it does not work for writing and result in corrupted registers when writing values with bit_offset > 0. Moreover, when a register is collocated with another one at the same address but with a different mask, the current code results in the other registers being overwritten with 0s. The write procedure for SYSTEM_MEMORY registers should actually read the value, mask it, update it and write it with the updated value. Moreover, since registers can be located in the same word, we must take care of locking the access before doing it. We should potentially use a global lock since we don't know in if register addresses aren't shared with another _CPC package but better not encourage vendors to do so. Assume that registers can use the same word inside a _CPC package and thus, use a per _CPC package lock.

2024-09-02drm/i915: Fix readout degamma_lut mismatch on ilk/snbVille Syrjälä
On ilk/snb the pipe may be configured to place the LUT before or after the CSC depending on various factors, but as there is only one LUT (no split mode like on IVB+) we only advertise a gamma_lut and no degamma_lut in the uapi to avoid confusing userspace. This can cause a problem during readout if the VBIOS/GOP enabled the LUT in the pre CSC configuration. The current code blindly assigns the results of the readout to the degamma_lut, which will cause a failure during the next atomic_check() as we aren't expecting anything to be in degamma_lut since it's not visible to userspace. Fix the problem by assigning whatever LUT we read out from the hardware into gamma_lut.

2024-09-02drm/i915: Do not attempt to load the GSC multiple timesDaniele Ceraolo Spurio
If the GSC FW fails to load the GSC HW hangs permanently; the only ways to recover it are FLR or D3cold entry, with the former only being supported on driver unload and the latter only on DGFX, for which we don't need to load the GSC. Therefore, if GSC fails to load there is no need to try again because the HW is stuck in the error state and the submission to load the FW would just hang the GSCCS. Note that, due to wa_14015076503, on MTL the GuC escalates all GSCCS hangs to full GT resets, which would trigger a new attempt to load the GSC FW in the post-reset HW re-init; this issue is also fixed by not attempting to load the GSC FW after an error.

2024-09-02pinctrl: qcom: x1e80100: Bypass PDC wakeup parent for nowStephan Gerhold
On X1E80100, GPIO interrupts for wakeup-capable pins have been broken since the introduction of the pinctrl driver. This prevents keyboard and touchpad from working on most of the X1E laptops. So far we have worked around this by manually building a kernel with the "wakeup-parent" removed from the pinctrl node in the device tree, but we cannot expect all users to do that. Implement a similar workaround in the driver by clearing the wakeirq_map for X1E80100. This avoids using the PDC wakeup parent for all GPIOs and handles the interrupts directly in the pinctrl driver instead. The PDC driver needs additional changes to support X1E80100 properly. Adding a workaround separately first allows to land the necessary PDC changes through the normal release cycle, while still solving the more critical problem with keyboard and touchpad on the current stable kernel versions. Bypassing the PDC is enough for now, because we have not yet enabled the deep idle states where using the PDC becomes necessary.

In tpm_set_next_event(delta), return -ETIME by wrong cast to int when delta is larger than INT_MAX. For example: tpm_set_next_event(delta = 0xffff_fffe) { ... next = tpm_read_counter(); // assume next is 0x10 next += delta; // next will 0xffff_fffe + 0x10 = 0x1_0000_000e now = tpm_read_counter(); // now is 0x10 ... return (int)(next - now) <= 0 ? -ETIME : 0; ^^^^^^^^^^ 0x1_0000_000e - 0x10 = 0xffff_fffe, which is -2 when cast to int. So return -ETIME. } To fix this, introduce a 'prev' variable and check if 'now - prev' is larger than delta.

Each condition binding to the same wait should be unique. AOAC code misused the wait of FW offload series and broke the above rule. It added another macro to generate wait condition of WoWLAN/AOAC, but the results conflict to the ones of FW offload series. It means that we might be completed wrongly in logic. We don't want things work/read like this and should have avoided this. Fix this by adding another wait which aims for WoWLAN functions.

2024-09-02wifi: rtw88: assign mac_id for vif/sta and update to TX descPing-Ke Shih
A mac_id as an instance in firmware has to be assigned for each station including AP and connected stations. Firmware will use the mac_id to control TX rate and do statistics. Assignment rule is to assign mac_id to each vif when adding vif. For station mode, sta->mac_id will reuse vif->mac_id. For AP mode, dynamically allocate an sta->mac_id to a station, and vif->mac_id is used to send broadcast/multicast packets which are not belong to a station. For example, vif->mac_id sta->mac_id vif0 (STA mode) 0 0 vif1 (AP mode) 1 2... By the way, remove unused RTW_BC_MC_MACID, which was planed to send broadcast/multicast packets on fixed mac_id.
