[PATCH v3 0/1] Add support for sun4i HDMI audio
by Stefan Mavrodiev 25 Feb '20

25 Feb '20

This patch series add support for HDMI audio for sun4i HDMI encored. The code uses some parts from the Allwinners's BSP kernel. In the previous patch series there was additional patch enabling the cyclic DMA transfers. It was accepted, so it's omitted here. The patch is tested on A20 chip. For the other chips, only the addresses of the registers are checked. Changes for v3: - Dropped the patch which enable the cyclic DMA transfers - In v2, a separate platform_driver was created. However this is not practical and the idea is dropped. - Since this module depends on SND_SOC, a new Kconfig entry is added. When SND_SOC is not enabled, the audio part is not initialized. - The "big" issue with v1 was that snd_soc_register_card() overwrites the driver_data pointer. To resolve this issue, the original pointer is stored as drvdata of the card. Then before card unregistering, the pointer is restored. This is done by calling additional destroy function. Changes for v2: - Create a new platform driver instead of using the HDMI encoder - Expose a new kcontrol to the userspace holding the ELD data - Wrap all macro arguments in parentheses Stefan Mavrodiev (1): drm: sun4i: hdmi: Add support for sun4i HDMI encoder audio drivers/gpu/drm/sun4i/Kconfig | 11 + drivers/gpu/drm/sun4i/Makefile | 3 + drivers/gpu/drm/sun4i/sun4i_hdmi.h | 37 ++ drivers/gpu/drm/sun4i/sun4i_hdmi_audio.c | 450 +++++++++++++++++++++++ drivers/gpu/drm/sun4i/sun4i_hdmi_enc.c | 14 + 5 files changed, 515 insertions(+) create mode 100644 drivers/gpu/drm/sun4i/sun4i_hdmi_audio.c -- 2.17.1

[RFC PATCH 0/3] KVM: x86: honor guest memory type
by Chia-I Wu 25 Feb '20

25 Feb '20

Hi, Host GPU drivers like to give userspace WC mapping. When the userspace makes the mapping available to a guest, it also tells the guest to create a WC mapping. However, even when the guest kernel picks the correct memory type, it gets ignored because of VMX_EPT_IPAT_BIT on Intel. This series adds a new flag to KVM_SET_USER_MEMORY_REGION, which tells the host kernel to honor the guest memory type for the memslot. An alternative fix is for KVM to unconditionally honor the guest memory type (unless it is MMIO, to avoid MCEs on Intel). I believe the alternative fix is how things are on ARM, and probably also how things are on AMD. I am new to KVM and HW virtualization technologies. This series is meant as an RFC.
