* drm/amd/pm: parse pp_handle under appropriate conditionsGuchun Chen2023-05-171-7/+13
| | | | | | | | | | | | | | | | | | | | commit 58d9b9a14b47c2a3da6effcbb01607ad7edc0275 upstream. amdgpu_dpm_is_overdrive_supported is a common API across all asics, so we should cast pp_handle into correct structure under different power frameworks. v2: using return directly to simplify code v3: SI asic does not carry od_enabled member in pp_handle, and update Fixes tag Link: https://gitlab.freedesktop.org/drm/amd/-/issues/2541 Fixes: eb4900aa4c49 ("drm/amdgpu: Fix kernel NULL pointer dereference in dpm functions") Suggested-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Guchun Chen <guchun.chen@amd.com> Reviewed-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* drm/amd/display: Enforce 60us prefetch for 200Mhz DCFCLK modesAlvin Lee2023-05-172-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | commit b504f99ccaa64da364443431e388ecf30b604e38 upstream. [Description] - Due to bandwidth / arbitration issues at 200Mhz DCFCLK, we want to enforce minimum 60us of prefetch to avoid intermittent underflow issues - Since 60us prefetch is already enforced for UCLK DPM0, and many DCFCLK's > 200Mhz are mapped to UCLK DPM1, in theory there should not be any UCLK DPM regressions by enforcing greater prefetch Reviewed-by: Nevenko Stupar <Nevenko.Stupar@amd.com> Reviewed-by: Jun Lei <Jun.Lei@amd.com> Cc: Mario Limonciello <mario.limonciello@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org Acked-by: Alex Hung <alex.hung@amd.com> Signed-off-by: Alvin Lee <Alvin.Lee2@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This is because the DPPCLK is stopped during the middle of an optimize_bandwidth sequence during commit_minimal_transition without going through plane power down/power up. [How] The intent of a 0Hz DPP clock through update_clocks is to disable the DTO. This differs from the behavior of stopping the DPPCLK entirely (utilizing a 0Hz clock on some ASIC) so it's better to move this logic to reside next to plane power up/power down where we gate the HUBP/DPP DOMAIN. The new sequence should be: Power down: PG enabled -> RCO on Power up: RCO off -> PG disabled Rename power_on_plane to power_on_plane_resources to reflect the actual operation that's occurring.

* irqchip/loongson-eiointc: Fix returned value on parsing MADTJianmin Lv2023-05-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | commit 112eaa8fec5ea75f1be003ec55760b09a86799f8 upstream. In pch_pic_parse_madt(), a NULL parent pointer will be returned from acpi_get_vec_parent() for second pch-pic domain related to second bridge while calling eiointc_acpi_init() at first time, where the parent of it has not been initialized yet, and will be initialized during second time calling eiointc_acpi_init(). So, it's reasonable to return zero so that failure of acpi_table_parse_madt() will be avoided, or else acpi_cascade_irqdomain_init() will return and initialization of followed pch_msi domain will be skipped. Although it does not matter when pch_msi_parse_madt() returns -EINVAL if no invalid parent is found, it's also reasonable to return zero for that.

| | | | | | | | | | | | | | | | commit c84efbba46901b187994558ee0edb15f7076c9a7 upstream. When support suspend/resume for loongson-pch-pic, the syscore_ops is registered twice in dual-bridges machines where there are two pch-pic IRQ domains. Repeated registration of an same syscore_ops broke syscore_ops_list, so the patch will corret it.

* irqchip/loongson-pch-pic: Fix pch_pic_acpi_init callingJianmin Lv2023-05-171-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 48ce2d722f7f108f27bedddf54bee3423a57ce57 upstream. For dual-bridges scenario, pch_pic_acpi_init() will be called in following path: cpuintc_acpi_init acpi_cascade_irqdomain_init(in cpuintc driver) acpi_table_parse_madt eiointc_parse_madt eiointc_acpi_init /* this will be called two times correspondingto parsing two eiointc entries in MADT under dual-bridges scenario*/ acpi_cascade_irqdomain_init(in eiointc driver) acpi_table_parse_madt pch_pic_parse_madt pch_pic_acpi_init /* this will be called depend on valid parent IRQ domain handle for one or two times corresponding to parsing two pchpic entries in MADT druring calling eiointc_acpi_init() under dual-bridges scenario*/ During the first eiointc_acpi_init() calling, the pch_pic_acpi_init() will be called just one time since only one valid parent IRQ domain handle will be found for current eiointc IRQ domain. During the second eiointc_acpi_init() calling, the pch_pic_acpi_init() will be called two times since two valid parent IRQ domain handles will be found. So in pch_pic_acpi_init(), we must have a reasonable way to prevent from creating second same pch_pic IRQ domain. The patch matches gsi base information in created pch_pic IRQ domains to check if the target domain has been created to avoid the bug mentioned above.

* drm/i915/dsi: Use unconditional msleep() instead of intel_dsi_msleep()Hans de Goede2023-05-174-30/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit c8c2969bfcba5fcba3a5b078315c1b586d927d9f upstream. The intel_dsi_msleep() helper skips sleeping if the MIPI-sequences have a version of 3 or newer and the panel is in vid-mode. This is based on the big comment around line 730 which starts with "Panel enable/disable sequences from the VBT spec.", where the "v3 video mode seq" column does not have any wait t# entries. Checking the Windows driver shows that it does always honor the VBT delays independent of the version of the VBT sequences. Commit 6fdb335f1c9c ("drm/i915/dsi: Use unconditional msleep for the panel_on_delay when there is no reset-deassert MIPI-sequence") switched to a direct msleep() instead of intel_dsi_msleep() when there is no MIPI_SEQ_DEASSERT_RESET sequence, to fix the panel on an Acer Aspire Switch 10 E SW3-016 not turning on. And now testing on a Nextbook Ares 8A shows that panel_on_delay must always be honored otherwise the panel will not turn on. Instead of only always using regular msleep() for panel_on_delay do as Windows does and always use regular msleep() everywhere were intel_dsi_msleep() is used and drop the intel_dsi_msleep() helper.

Might not be 100% accurate, but should at least be safe. We can refine the limits later if we discover that recent hw is less restricted.

| | | | | | | | | | | | | commit 6c950c20da38debf1ed531e0b972bd8b53d1c11f upstream. The WM8960 Linux driver expects the clock to be named "mclk". Otherwise the clock will be ignored and not prepared/enabled by the driver.

While I'm not aware of any problems that have occurred running these at 100 MHz, the official word from ASRock is that 50 MHz is the correct speed to use, so let's be safe and use that instead.

| | | | | | | | | | | | | | | | | | | | commit 228b09de936395ddd740df3522ea35ae934830d8 upstream. Relatively new docs which I added which hinted the base directories needed to be created before is wrong, remove that incorrect comment. This has been hinted before by Eric twice already [0] [1], I had just not verified that until now. Now that I've verified that updates the docs to relax the context described.
