Move blog posts to the posts/ directory.

We also have two other pages that are not generated from the blog posts
(reply.html and search.html).

It would be nice to be able to move them to markdown as well, but if we do
that it is necessary to differenciate between markdown files used to generate
blog posts, and the ones used to generate these pages.

In addition if the blog posts directory is named markdown, and that we have
other markdown files as well, it become confusing for contributors.

-title: Final days for the upstream Linux Allwinner VPU support crowdfunding campaign

-A [crowdfunding campaign][1] was launched over a month ago by [Bootlin][2] in
-order to fund the development of an [upstream Linux kernel driver for the
-Allwinner CedarX VPU][3]. The VPU (Video Processing Unit) is in charge of
-offloading video decoding and encoding to a dedicated hardware block,
-relieving the main CPU. While Replicant does not support Allwinner devices at
-this point, the project has acquired a number of Allwinner tablets a few years
-ago, that helped with the advancements of Allwinner platforms support in
-upstream projects such as the [U-Boot][4] bootloader and the [Linux
-kernel][5].
-
-Recently, Replicant was a candidate for the Google Summer of Code program and
-we came up with a [list of tasks for the occasion][6]. Although our
-application was not accepted, we are still interested in completing the tasks
-that we picked up. We put a deliberate focus on supporting mobile devices in
-mainline U-Boot and Linux, with a particular emphasis on Allwinner devices,
-the Optimus Black and the Kindle Fire (first generation). We believe that
-supporting mobile devices and using standard driver interfaces in the upstream
-Linux kernel is the only sustainable way for freedom on mobile devices.
-Instead of writing device-specific code specifically for Android for each of
-the supported devices, this would allow using generic Hardware Abstraction
-layers (HALs), reducing the amount of work for hardware support on the
-Replicant side in the long run. This also allows running other operating
-systems that integrate the upstream Linux kernel interfaces, such as standard
-GNU/Linux distributions.
-
-In spite of this, I have been dedicating more and more time to contributing to
-upstream projects such as [coreboot][7], [U-Boot][8] and [Linux][9] for
-supporting devices of various form factors, including mobile devices, laptops
-and single-board computers. Thus, I became less and less active on the
-technical side for Replicant, where Wolfgang and others have picked-up the
-work. There is still a lot of room for contributions and everyone is warmly
-encouraged to join-in and help with the upstreaming effort for devices,
-especially regarding the Optimus Black, Kindle Fire (first generation) and
-Allwinner devices.
-
-As a student approaching graduation, I have joined [Bootlin][2] (formerly Free
-Electrons) in Toulouse, France for an internship focused on supporting the
-[Allwinner VPU][10] in upstream Linux and userspace. It definitely fits
-perfectly with the logic behind focusing Replicant towards upstream Linux
-support. In order to accelerate the development of the driver, Bootlin has
-decided to start a [crowdfunding campaign][1] in order to fund Maxime Ripard,
-who has been working for the company and maintaining [Allwinner platforms in
-the Linux kernel][11] for a while.
-
-As the main goal of the campaign was reached within its first week, Maxime
-will be able to work with me on the VPU. His in-depth understanding of the
-[sun4i DRM video driver's innards][12] will also reveal very useful for
-accelerating the processing of the frames coming from the VPU (without
-unneeded copies of buffers) and implementing scaling in hardware. In order to
-support the VPU hardware efficiently, a number of changes have to be
-introduced to the Linux kernel. It currently lacks an interface to provide
-coherency between setting specific controls for the media stream and the
-input/output buffers that these controls are related to and should apply to.
-This API has been implemented by Alexandre Courbot (who's working at Google on
-the Chromium OS project) as the [V4L2 request API][13], that fits the
-requirements for the Allwinner VPU driver. Other VPU drivers, such as the
-[tegra-vde driver][14] that supports the Tegra 20 video decoder engine, also
-require this API in order to implement a proper [V4L2 mem2mem driver][15].
-
-The [crowdfunding campaign][1] still has 10 days to go and two stretch goals
-to meet (while the first stretch goal, about supporting newer Allwinner SoCs
-was already met):
-
-* H265 video decoding support
-
-* H264 encoding support
-
-> As I am not directly impacted by the funding received through the
-> crowdfunding campaign, we believe that there is no direct conflict of
-> interest writing this blog post on the Replicant blog.
