intel/display: replace intel_fbdev with drm/kms Fixes #4806 2023-03-24 15:01:48 +00:00			`PATCH_FILES := i915_irq.patch \`
lx_emul: update Linux port to 6.1.20 Fix genodelabs/genode#4798 2023-03-23 10:20:43 +00:00			`iwlwifi_enable_irq_before_pnvm.patch \`
iwlwifi: limit rx bufs to 2048 Recent devices are configured with 4096 RX pages that lead to an increased memory usage. For the moment lower the amount to 2048 and treat in potientially lower throughput for more conservative memory consumption. Fixes #4801. 2023-04-03 09:37:45 +00:00			`iwlwifi_limit_rx_bufs.patch \`
dde_linux: prevent scatter-gather in USB devio USB devio splits large transaction into 16 KiB buffers in scatter-gather lists. Unfortunately, this mechanism seems unreliable most certainly because of issue #4809 "DDE Linux struct page object aliasing". Issue #5036 2023-07-11 06:16:18 +00:00			`usb_host_devio_sg.patch \`
linux.port: lxip_checksum_32.patch CONFIG_X86_USE_PPRO_CHECKSUM is a 'def_bool y' and gets re-enabled by 'make olddefconfig'. The PPRO version contains text relocations which we cannot have in binaries (e.g., 'lea 45f(%ebx ...).'). issue #5104 2023-09-12 17:52:58 +00:00			`lxip_checksum_32.patch \`
linux.port: lxip_ip_config.patch The patch makes it possible to re-configure the IP settings via DHCP or static. issue #5104 2023-12-04 18:07:41 +00:00			`lxip_ip_config.patch \`
linux.port: add usb_net_pinephone.patch The PinePhone Modems' CDC Ethernet Interface does not respond if RX/TX queue size is greater 12 (experimentally determined), the default would be 60, meaning 60 RX Bulk URBs are sent at once to the device. issue #4958 2023-07-14 09:07:26 +00:00			`usb_net_pinephone.patch \`
linux.port: add usb_net_cdc_ncm.patch NCM tries to batch TX packets using timeouts (500us) and does not send packets before 3 packets are in the submit queue. Timeouts take milliseconds on dde_linux which leads to delayed ACKs and poor performance for the RX case. Therefore, we send small packets (<100 Bytes) immediately without batching (it might be an ACK or last packet of a larger transfer). issue #4958 2023-08-18 17:32:16 +00:00			`usb_net_cdc_ncm.patch \`

linux: allow more workers when scheduling works Workers are only summoned by the manager or when there are no workers on a work queue. In case a work in front of a work queue depends on a work behind it, a deadlock may occur. To solve this Linux spawns a rescue worker using timers. Timing of Linux based drivers is currently reworked and not reliable. Therefore, we increase the number of workers that are spawned from 1 to 3 per work queue in order to resolve possible deadlocks.
