Instead of a pixel and +framebuffer format, it only accepts a color mode of vague semantics. Assuming +a linear framebuffer, the color mode gives an idea of the supported pixel +format. But userspace effectively has to guess the correct values. It really +only works reliably with framebuffers in XRGB8888. Userspace has begun to +workaround these limitations by computing arbitrary format's buffer sizes and +calculating their sizes in terms of XRGB8888 pixels. + +One possible solution is a new ioctl DUMB_CREATE2. It should accept a DRM +format and a format modifier to resolve the color mode's ambiguity. As +framebuffers can be multi-planar, the new ioctl has to return the buffer size, +pitch and GEM handle for each individual color plane. + +In the first step, the new ioctl can be limited to the current features of +the existing DUMB_CREATE. Individual drivers can then be extended to support +multi-planar formats. Rockchip might require this and would be a good candidate. + +It might also be helpful to userspace to query information about the size of +a potential buffer, if allocated. Userspace would supply geometry and format; +the kernel would return minimal allocation sizes and scanline pitch. There is +interest to allocate that memory from another device and provide it to the +DRM driver (say via dma-buf). + +Another requested feature is the ability to allocate a buffer by size, without +format. Accelators use this for their buffer allocation and it could likely be +generalized. + +In addition to the kernel implementation, there must be user-space support +for the new ioctl. There's code in Mesa that might be able to use the new +call. + +Contact: Thomas Zimmermann <tzimmermann@suse.de> + +Level: Advanced Better Testing ============== diff --git a/drivers/accel/amdxdna/Makefile b/drivers/accel/amdxdna/Makefile index 6797dac65efa..6344aaf523fa 100644 --- a/drivers/accel/amdxdna/Makefile +++ b/drivers/accel/amdxdna/Makefile @@ -14,6 +14,7 @@ amdxdna-y := \ amdxdna_mailbox.o \ amdxdna_mailbox_helper.o \ amdxdna_pci_drv.o \ + amdxdna_pm.o \ amdxdna_sysfs.o \ amdxdna_ubuf.o \ npu1_regs.o \ diff --git a/drivers/accel/amdxdna/aie2_ctx.c b/drivers/accel/amdxdna/aie2_ctx.c index e9f9b1fa5dc1..691fdb3b008f 100644 --- a/drivers/accel/amdxdna/aie2_ctx.c +++ b/drivers/accel/amdxdna/aie2_ctx.c @@ -21,6 +21,7 @@ #include "amdxdna_gem.h" #include "amdxdna_mailbox.h" #include "amdxdna_pci_drv.h" +#include "amdxdna_pm.h" static bool force_cmdlist; module_param(force_cmdlist, bool, 0600); @@ -88,7 +89,7 @@ static int aie2_hwctx_restart(struct amdxdna_dev *xdna, struct amdxdna_hwctx *hw goto out; } - ret = aie2_config_cu(hwctx); + ret = aie2_config_cu(hwctx, NULL); if (ret) { XDNA_ERR(xdna, "Config cu failed, ret %d", ret); goto out; @@ -167,14 +168,11 @@ static int aie2_hwctx_resume_cb(struct amdxdna_hwctx *hwctx, void *arg) int aie2_hwctx_resume(struct amdxdna_client *client) { - struct amdxdna_dev *xdna = client->xdna; - /* * The resume path cannot guarantee that mailbox channel can be * regenerated.
