| 8 years 10 months | mmc: jz4740: prepare next dma transfer in parallel with current
transfer Make use of the MMC asynchronous request capability to prepare the next DMA transfer request in parallel with the current transfer. This is done by adding pre-request and post-request callbacks that are used by the MMC framework during an active data transfer. It should help reduce the impact of DMA preparation overhead on the SD card performance. Signed-off-by: Apelete Seketeli <apelete@seketeli.net> |
| 9 years 4 months | mmc: jz4740: add dma infrastructure for data transfers Until now the MMC driver for JZ4740 SoC was relying on PIO mode only for data transfers. This adds a DMA infrastructure for data trasnfers in addition to PIO mode by relying on DMA Engine. DMA tranfers performance might be further improved by taking advantage of the asynchronous request capability of the MMC framework. Signed-off-by: Apelete Seketeli <apelete@seketeli.net> |
| 9 years 22 days | dma: jz4740: complete descriptor before marking it null In order to call vchan_cookie_complete() on DMA descriptor, we need a valid address to be dereferenced. This fixes the sequence where descriptor is marked NULL before being dereferenced for completion, thus causing a kernel paging request fault. Signed-off-by: Apelete Seketeli <apelete@seketeli.net> |
| 9 years 1 month | mmc: jz4740: don't wait for PRG_DONE after stop command with R1
response As of commit bcc3e1726d ("mmc: block: Use R1 responses for stop cmds for read requests"), stop commands for reads do not have MMC_RSP_BUSY set. In this case we should not wait for a PRG_DONE IRQ after sending the stop command: it will not get raised when the busy flag is not set, causing the request to fail with a timeout.

| 12 years 9 months | Add defconfig for the Dingoo A320 This is the config from the jz-3.5 branch brought up to date for 3.6. |
| 12 years 2 days | OpenDingux: Add initrd The initrd contents are specified using initrd/tree.txt. The gen_init_cpio tool will parse that text file and generate a cpio archive. splashkill is a simple program that is meant to be launched directly by the kernel, before mininit. It forks itself and sleeps until the ENTER key is pressed; when it occurs, it enables the framebuffer console by writting to a file in /sys. This permits to 'kill' the kernel splash screen, in order to display the boot log. The source for the mininit and splashkill binaries can be found here: https://github.com/Ayla-/mininit |
| 11 years 4 months | OpenDingux: Add logo We have a full-screen logo that is used as a splash screen. |
| 12 years 2 months | MIPS: A320: Add Dingoo A320 board support This is a squashed version of the development done in the jz-3.5 branch. |
| 11 years 10 months | MIPS: A320: Add SoC sound support for Dingoo A320 |
| 10 years 11 months | MIPS: JZ4740: Work around fbcon logo crash with SLCD The logo data is in the init section. However, when using the SLCD driver, the fbcon code will try to fetch the logo data after the init section has already been freed, potentially crashing the kernel. This is a workaround because we have to release a stable kernel now. The root cause should be found and fixed later. |
| 11 years 11 months | MIPS: JZ4740: SLCD framebufer driver This driver sends the frame buffer to a smart LCD controller, that is a controller with its own video memory. It is a squashed version of development done in the jz-3.5 branch. |
| 11 years 11 months | MMC: JZ4740: Added support for CPU frequency changing The MSC device clock is stopped before the frequency change. After the change a new divider is computed and the clock is restarted. Also the frequency change is postponed if an I/O operation is in progress. |
| 12 years 2 months | MIPS: JZ4740: Add cpufreq support This is a squashed version of Uli's driver that was further developed in the qi-kernel repository. |
| 12 years 9 months | MIPS: JZ4740: Added setting of PLL rate and main dividers This functionality makes a cpufreq driver possible. Squashed version of the development done in the jz-2.6.39 branch. |
| 12 years 7 months | qi_lb60: Don't use 3-wire spi mode for the display for now The spi_gpio driver does not support 3-wire mode. |
