[PATCH 00/14] rtlwifi: remove duplicate C2H handlers

[PATCH 00/14] rtlwifi: remove duplicate C2H handlers

[pkshih]

From: Ping-Ke Shih <pkshih@realtek.com>

The goal of patch 1/14 and 2/14 is to use keep-alive mechanism in mac80211
stack that needs accurate TX ack status for null frame reported by firmware
through C2H.
The remaining patches are step by step to remove duplicate C2H handlers
that widely distributed in IC specific files. An example of calling flow
before this patchset is:
	_rtl_pci_rx_interrupt() -> 
	rtlpriv->cfg->ops->rx_command_packet() =
		rtl8723be_rx_command_packet() -->
	rtl8723be_c2h_packet_handler() -->
		case 1: rtl_c2hcmd_enqueue()
		case 2: rtl8723be_c2h_content_parsing()

	if case 1:
	rtl_c2hcmd_launcher() ->
	rtlpriv->cfg->ops->c2h_content_parsing() =
		rtl8723be_c2h_content_parsing()

This patchset remove two ops:
	rtlpriv->cfg->ops->rx_command_packet()
	rtlpriv->cfg->ops->c2h_content_parsing()

But a special C2H is still existing, so add one op for RA report:
	rtlpriv->cfg->ops->c2h_ra_report_handler()

Finally, calling flow becomes:
	_rtl_pci_rx_interrupt() -->
	rtl_c2hcmd_enqueue() -->
		case 1: enqueue
		case 2: rtl_c2h_content_parsing() if fast_cmd
	
	if case 1:
	rtl_c2hcmd_launcher() ->
	rtl_c2h_content_parsing() ->
	hal_ops->c2h_ra_report_handler() =
		rtl8821ae_c2h_ra_report_handler() if C2H_RA_RPT

[PATCH 01/14] rtlwifi: support accurate nullfunc frame tx ack report

[pkshih]

From: Tzu-En Huang <tehuang@realtek.com>

In order to realize the keep-alive mechanism in mac80211 stack, reporting
accurate tx ack status for nullfunc frame is added in this commit.

If current frame is nullfunc frame, we ask firmware to report by filling
TX report bit in TX descriptor. After this frame DMA done, TX interrupt is
triggered but TX status is unknown at this moment, so enqueue this skb
into tx_report->queue. Finally, C2H report will be received if the frame
is transmitted successfully or retried over, and then we report to mac80211
with IEEE80211_TX_STAT_ACK flag only if it's successful. Otherwise, if
failure or timeout (one second), we report to mac80211 without this flag.

[PATCH 04/14] rtlwifi: rename register-based C2H command IDs to V0

[pkshih]

From: Ping-Ke Shih <pkshih@realtek.com>

Current chips use packet-based C2H commands whose IDs differ from old
ones, so this commit simply gives C2H_V0_ as prefix of command IDs.

[PATCH 07/14] rtlwifi: remove dummy hal_op rx_command_packet from rtl8188ee and rtl8723ae

[pkshih]

From: Ping-Ke Shih <pkshih@realtek.com>

The caller of hal_op rx_command_packet will assert function pointer
before calling, so we can remove dummy functions safely.

[PATCH 08/14] rtlwifi: Add hal_op c2h_ra_report_handler for special process

[pkshih]

From: Ping-Ke Shih <pkshih@realtek.com>

We're going to merge C2H handler into one, but one special case is to
handle RA_REPORT that implements in individual IC folder. So this commit
adds a hal_op for caller in common code.

[PATCH 10/14] rtlwifi: remove hal_op rx_command_packet

[pkshih]

From: Ping-Ke Shih <pkshih@realtek.com>

Because the hal_op rx_command_packet does C2H handler if rx packet type
is C2H, and the handler have been moved to base.c so we can call the
handler directly.

[PATCH 11/14] rtlwifi: remove hal_op c2h_content_parsing

[pkshih]

From: Ping-Ke Shih <pkshih@realtek.com>

Similar to rx_command_packet, we can call rtl_c2h_content_parsing so the
hal_op isn't necessary.

[PATCH 12/14] rtlwifi: use sk_buff to queue C2H commands

[pkshih]

From: Ping-Ke Shih <pkshih@realtek.com>

We use 'struct rtl_c2hcmd' to store C2H commands originally, and the code
is slightly complex to enqueue and dequeue and also wastes time to
allocate and memcpy data. Since C2H commands are asynchronous events,
they can be processed in work queue, so RX ISR enqueues C2H result in
removal of rtl_c2h_packet_handler().

[PATCH 13/14] rtlwifi: access skb->data to get C2H data by macro

[pkshih]

From: Ping-Ke Shih <pkshih@realtek.com>

The format of C2H data is ID(1 byte) + Length(1 byte) + value, and it is
more readable to use macros to access C2H data.

[PATCH 14/14] rtlwifi: fix btmpinfo timeout while processing C2H_BT_INFO

[pkshih]

From: Ping-Ke Shih <pkshih@realtek.com>

In former patch, I enqueu all C2H commands and processed by a workqueue.
In case C2H_BT_INFO will issue a H2C command to set BT reg, and wait for
a C2H ack. But it is totally impossible that C2H workqueue waits for a
C2H command, so kernel log warn
	rtlwifi: :<0> btmpinfo wait (req_num=0) timeout

Since the C2H ack command C2H_BT_MP can be safely processed in interrupt
context, add a fast command path to deal with the command.

These macros are not really pretty, a proper static inline function
would be a much better choise. But I'm planning to apply this patch
anyway, I don't think it's a blocker but a good idea to cleanup later.

And rtlwifi really should get away with this foo[0] and foo[1] style of
buffers and switch to proper structs (foo->bar and foo->koo).

With u8 you don't need endian check, right? I would assume that with
both little and big endian bar and koo would be in the same place.

Earlier bitfields were disliked but nowadays they seem to be have become
more acceptable. But I think the preferred way still is something like
this (using u32 and 16 bit fields):

struct foo {
        __le32 koobar;
}

#define RTLWIFI_BAR_MASK GENMASK(15, 0)
#define RTLWIFI_KOO_MASK GENMASK(31, 16)

bar =3D FIELD_GET(RTLWIFI_BAR_MASK, __le32_to_cpu(foo->koobar));
koo =3D FIELD_GET(RTLWIFI_KOO_MASK, __le32_to_cpu(foo->koobar));

Of course there can be other good ways to do the same, others can chime
in about those, but this is how I would do it.

To me that does not make any sense, I have never heard about bit
endianness any of the devices I have worked on.

Unfortunately, the order in which these fields are laid out is different
between big and little endian, even when only dealing with u8.
That alone is a strong reason to avoid bitfields entirely for anything
shared between the host and something else.

Oh, didn't know that. Can you give some examples about endian problems
with u8 bitfields? Still not getting it. Not that it matters, just
curious.

Kalle,

By now, I think you understand that not only the byte order is different between 
BE and LE, but the bit order within a byte is different as well. In the normal 
situation where only byte-sized quantities are involved, then there need not be 
any concern. If you need to mask part of the byte, the mask itself will be in 
the correct endianess.

To me, the main advantage of using using bitfield notation is that the compiler 
does the work of generating the masks needed to extract a portion of the byte. I 
consider that to be slightly less likely to have errors that relying on the 
programmer to generate the mask. A secondary benefit is that the bitfield 
notation is self documenting.
